Solved: Lock ups due to DHCP / network card issue?

Q: Solved: Lock ups due to DHCP / network card issue?

I have a problem with my pc randomly locking up and having to be rebooted. I believe it has to do with the wireless card accessing my network, but I canít figure out how to troubleshoot it. (If this is the wrong forum, please let me know!)

I have a desktop, two laptops, and a printer on a wireless network. All of them have been working fine. Then, about a month ago, I loaded a new game on my desktop, which worked entirely fine for roughly three weeks. Then last week, I tried setting up a server in the game. On my first attempt, it locked up my pc at the setup server stage, and I had to reboot. On my second attempt, I tried a slightly different configuration, and it created a local server and worked just fine.

Everything seemed okay for a couple of days, and then the game started to lag after a few minutes of play. After two or three more rounds of play, the lag was then accompanied by the pc locking up. Couldn't figure out why, so I stopped playing it.

Within a day or two, my desktop would randomly freeze without warning, with no clear connection to any specific application or time of day. This has continued to today. Sometimes the lock up is preceded by erratic behavior, such as the wireless keyboard freezing up though the companion wireless mouse will work (or vice versa) and an occasional USB connecting-then-disconnecting sound, though nothing had been touched. Sometimes the lock up is for 10 seconds or so. Most of the time, though, there are no warnings, and it just hangs and requires a reboot.

By hangs, I mean mouse and keyboard have no effect. Strangely enough, I can often see traffic on the ZoneAlarm bar even though the pc seems immobilized.

The only clue I have thus far comes from the Event Viewer. Just before a lock up, there are multiple incidents of the same warning: ďYour computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address [pcís physical address]. The following error occurred: The operation was canceled by the user. . Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.Ē There are never any error messages, just the warnings.

I access my network through a USB wireless adapter, which has worked fine for about 5 months and connects just fine until things freeze. Iíve checked and re-checked the IP configuration and canít find anything thatís wrong. I've checked device manager, and nothing is out of whack. The only way to avoid the lock ups thus far has been to disconnect my USB wireless adapter Ė not an acceptable solution obviously.

Iíve run complete virus scans and multiple spyware apps. Everything checks out clean. Iíve doublechecked to make sure that Iíve not installed anything near or after the time the problems first started. I even checked the date of the last XP SP3 download to see if it took place near the start of the problems, but no. The driver on the wireless adapter is current.

Iím stumped! Any advice?

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

Having trouble with my Windows 7 Ultimate (64-bit) wired LAN connection. Yesterday evening everything was fine, I was connected and doing some remote work into the office - I was playing with OpenVPN connections. I left the machine for a few hours logged on, came back and now the NIC appears dead.

I have restored windows to the point just before i installed Open VPN.

I get "Unidentified network" and "no internet connection" for my LAN connection in Network Centre. There's no gateway or ip assigned looking at ipconfig /all, just the self assigned 169.* ip

The ethernet cable is connected directly into my cable modem (note, not a router).

I have googled a lot and have tried (not necessarily in this order):

1. Ensured its not the WAN/RJ-45 cable - have connected successfully with an older laptop's LAN NIC. When switching machines i turn off both the machine and the modem for 30 secs, and typically tun network troubleshooter to reset the LAN.
2. Tested the internal NIC by pinging, loopback successful.
3. Uninstalled the LAN NIC and reinstalled it.
4. Removed all clients & protocols from the NIC's properties bar IPv4 and Microsoft Client for windows i.e. specifically removed IPv6.
5. Reset TCP/IP using netsh int ip reset c:\resetlog.txt.
6. Have removed the wireless adapter. The only network connection is the internal NIC.

All forums I've scoured suggest one or more of these things, so I'm exhasuted of ideas.

A:DHCP Server using (1) Network card

Read other 10 answers

I warmly welcome

I have a problem with configuring network cards

WIFI comes nicely with DHCP pool 192.168.0 .*

I have a virtual network adapter "Microsoft Loopback Adapter"
in it I have to have a static IP address
and set it manually (IPv4)

the problem is that the WiFi card is still changing my IP address of the virtual card

how to prevent it?

I wanted to wifi card automatically collects the IP address
but did not interfere in the virtual adapter's IP

A:Wifi DHCP - the second network card on a fixed IP

I quote (from ):

Microsoft Loopback Adapter is a dummy network card, no hardware is involved. It is used as a testing tool for a virtual network environment where network access is not available. Also, you must use the Loopback adapter if there are conflicts with a network adapter or with a network adapter driver. You can bind network clients, protocols, and other network configuration items to the Loopback adapter, and you can install the network adapter driver or network adapter later while retaining the network configuration information.

Given that, there is no way your wi-fi card can "change" the IP address of your fake network adapter. If you set a static IP for ANY adapter, it WILL stay that way, regardless if one adapter is set to release and renew based on DHCP and one is not.

I even tried it myself. I installed the loopback adapter, set an IP and all that for it, released ALL DHCP'd IPs and renewed them. the static IP for the loopback adapter didn't change.

Take a look at your settings again, make sure you didn't miss something.

Hello All, My company has been buying the M910Z systems since last year and I have noticed that the NIC card on these things will just randomly not pick up an IP address via DHCP when the PC is first powered on or when a network cable is unplugged. This doesnt happen everytime, but there are instances when the PCs go to sleep and the user is unable to connect back to the network due to the PC dropping the network connection. To resolve the issue, i have to either shut the PC down and then boot it back up or go into the control panel, diable/enable the NIC card in hopes for it to grab an IP. Is there a fix to this issue because im assuming its either a BIOS or NIC driver issue because I have isolated the issue down to these PCs and i wanted to see if the community could help me out here.

Lightening fast network speed has slowed to a crawl. The machine has two wireless network cards:
-TP-Link 450 Mbps Wireless N adaptor
-Ralink RT61 Turbo

With the "Local Area Connection Status" window open I could see the computer receiving a good volume of download and then it would stop. Sometimes it might recover briefly, other times not. To complete a download, I had to disable/enable the network card and then a burst of good download activity before it stalled again. This is a Win7/64 machine. Another Win7/64 machine on the same network is having no problem.

Checked that the latest drivers are installed. Disabled both cards in Device Manager. Enabled the Ralink card when it came active it also brought along "Microsoft Virtual WiFi miniport adaptor." No clue why this popped up. I have an internet connection (a very slow one - 0.5-1 Mbps download with a 50Mbps connection to the ISP - Verizon FIOS). Although I have a connection, in the system tray there is a big red "X" on the wireless icon. Don't know if that is a clue or a quirk

Physically removed the NIC cards, removed the power cord, powered on without the cord to drain any residual memory. Reinstalled one at a time. No change, except Windows is complaining about the driver on the TP-Link card. Will try to find a fresh copy of that driver that was originally downloaded from the Internet.

Have scanned for spyware, virusus, malicious software, System Mechanic - no change.

My friend and I are currently working on setting up a network in his new office to open soon.

I have run into a situation that we both do not understand how to fix.

There are 3 computers:
1 laptop (access Internet through wireless router)
1 desktop (access Internet through wired)
1 small buisness server 2k3 (used mainly for a client/server program used towards his occupation)

We setup the server today, it came preconfigured with windows 2k3 small buisness server. After installation was all complete, we then created a domain (NWSRV) and obviously the server was the DC.

At first, we did not install/configure DHCP on the server, bc we thought just to let the router provide this. (We later figured this is where the problem started) So then the server was provided with a IP from the router, and could access the internet. But yet, none of the PC's could connect to the domain - the desktop keeps coming up with an error along the lines of "DNS name for the DC not found."

The setup:
Comcast provides DSL internet connection to a modem, which then plugs into a netgear wireless/wired router. The router then has the desktop and server plugged into it.

The server is obtaining its IP through the netgear router i believed, so i went into the router and configured the router to "NOT act as a DHCP server." In hope that this would rectify the situation, yet then none of the computer could access the Internet and still no joining of the domain.

We have over 50 XP computers on our network. Most get their IP's via DHCP (From a MS DC)...
I have one computer that is assigned it's IP statically but every-time it reboots or the network is disconnected and re-connected the DHCP address leases shows a dynamic IP assigned to the MAC address of the NIC.
This makes it so when pinging the computer name it generally responds with the dynamic IP. But when on the actual system itself it is assigned a static IP!
This system with the static IP is Windows XP, we do have many other XP based machines with static IP's that are NOT also getting dynamic IP's.
I've tried a few different static IP's
drivers are fully up to date
tried disabling the dhcp service and rebooting, but still no luck.

I'm not sure where else to try looking. About the only thing I haven't done is replace the NIC...

I am setting up a linux box for a server on my home network which is DHCP, I don't want to change the entire network, I just need this server to have a static IP (so that I can get port forwarding to work). I don't even know if this is possible, if I were to give the server a static IP can my router deal with it, even though everything else is DHCP? My router is a linksys WRT54GS if that helps any.
An answer to this would be much appreciated. ^_^ Thanks

A:Solved: Is it possible to have one computer with Static IP on a DHCP Network?

Yes just make sure it sits outside of your DHCP scope so if DHCP starts at and has 100 seats then make the machine be or lower or and higher and it would be fine. Make sure to copy all other items from what DHCP would give you. E.G. DNS, Subnet mask and gateway.

When logging onto the company network via a RAS server, the DHCP active leases is not being updated with the IP address assigned to me. This is the case both when the RAS server is configured to give an IP address from a fixed pool, or when configured to obtain IP address from DHCP. As a result, I'm experiencing problems if an existing lan device has an IP address assigned and the dialed in device grabs that address. Whats going on ?

A:{Solved} - DHCP active leases not being updated when dialing into network via RAS server


There should be a clear distinction between the IP adresses available for the network, and those available for the Dial up users. Do not make them part of the same IP group.

The reason is that Dial-up IP addresses should have a lease time of a few hours, and the LAN lease time should be that of a few days. This is obviously not compatible, so they need to be seperate.

Hope this helps

I'm running a simple network at home with a Linksys BEFSR41 router. I have two computers hooked up wired and a wireless router acting like an access point that I use for my laptop occasionally. Until this weekend I've been having no problems but I shut down the computers due to weather and now one of them is not able to communicate with any others on the network. The problem computer will get an address supplied to it by the router (DHCP server) but once it has it I cannot get any other connectivity. Of course this is hindering internet access on this computer. I can ping the loopback and assigned IP addresses w/o problems but when I ping the default gateway (router) and/or the other computer I get "Request timed out." I initially thought it was the NIC so I bought another one but still get the same issue. I've moved the cards to different PCI slots but no luck. I tested the cable running from the computer and the router but found no problems. I even tried resetting the TCP/IP stack but still didn't work. The computer in question is running WinXP SP2 with the original NIC being a Linksys LNE100TX and the new one being a D-Link DFE-530TX+.

Any clues on this? If more info is needed let me know--it's been a while since I've posted. Thanks in advance.

Okay, I got a new client a few weeks ago. What a mess...anyway, they had bought a new Dell with SBS 2K3 on it, and for some reason they have a wired firewall (Linksys), a wireless router (Linksys) and a small switch. After examining the setup of the network, I found the wireless router giving out IP addresses in the 192.168.1.X range, the SBS being what it is, was going to be the DNS/DHCP/DC, on and on, etc. I turned off the DHCP on the wireless router. Yesterday they called and had a machine that I wasn't aware of that couldn't connect, it's a proprietary machine for X-Rays, and all I could do was really look at it, and do a few things, like change the IP if needed, but it's set to DHCP, and it's getting 192.168.1.X addressing, when umm, it can't be. I did ipconfig /release then /renew, nothing, still the old address, with as the DCHP and gateway. I statically set it to the 192.168.0.X settings and nothing, can't ping in or out or see the network. I set it back to DCHP reboot, and it still gets 192.168.1.X address, but there is no DHCP server serving up these address, so ummm, anyone? Oh, the X-Ray comp is plugged directly into the firewall now wich is on the 192.168.0.X network on the inside.......

When my wife tries to log in to her computer, it gives her a message stating that her caps lock key is on, but she can't turn it off...I'm nowhere near the laptop so I'm relaying this info second hand. There is a triangle with an exclamation mark and it says "Caps lock is on." She says when she clicks the message, it tells her to access the on-screen keyboard, but using the mouse to turn of caps lock there doesn't work either.

She also just informed me that the caps lock key is on for everything...firefox, word, notepad etc, so I assume it's a keyboard issue, not a log in issue. When she presses shift, it goes to lower case. I had her go to control panel, region and language, keyboards and languages, hit the change languages button to open text services, opened the advanced key settings, and the "press the CAPS LOCK key" choice was in fact selected, so I don't know what to try next. Maybe to enter safe mode to see if the problem exists there too? But I don't know how to get into safe mode on her computer, and neither does she, apparently. F2 seems to be the bios from her description and F12 seems to be the boot menu, but no safe mode selections...only drive choices. Her laptop is an Acer Aspire 5534...that's all I know...for now.

Hey guys. I work in an IT department at a rather large facility doing desktop support. Recently myself and a couple of the other guys in the department have come across 10-15 machines that all are sharing this problem. The network cards are working fine one day, then the next day they are showing up under the "Unknown Device" category in the Device Manager. The interesting thing is that the name of the card still shows up fine, it is just under the Unknown Device category with the exclamation next to it. We have tried everything we can think of with no luck. We uninstalled and reinstalled the device, swapped in new NIC cards under different PCI slots, ran spybot and ad aware, all of the machines are protected by Trend Antivirus and are not showing any viruses, we even did Windows repairs and its not working. This is happening on both 2000 and XP machines that are fully patched. The only way we have been able to fix this and get connectivity back to the machines is by doing over the top windows installs or formatting and starting over completely. Has anyone else ran across this and know of a better fix?

So, I recently replaced my motherboard in my A75-S226 Toshiba laptop. The board didn't come with a wireless card, so I used the one from my old motherboard. When I booted up for the first time, I received a "Network resource conflict" error, citing Slot 3, Bus 2, Device 3, Function 0 as the source of the problem. After I booted, neither the wireless or wired network function worked. In Device Manager, it recognizes a "Unknown PCI device" in that same resource location (Slot 3, Bus 2, Device 3, Function 0). Is this just a matter of re-installing the drivers from a Windows CD? Or do I have to modify something?

hi guys I've been a long time reader here at techspot and I've got to say i love the website. Now for the most part i consider myself pretty familiar with computers and i can handle just about anything as far as computer problems go. However this one has me stumped, so i figured i could turn to the most knowledgeable computer gurus around. So my problem is Windows seems to be dedicating a little over 2 gigs of ram for my wireless card. Now this is odd because I've never heard of a wireless card needing memory dedicated for it let alone 2 gigs worth. i can tell it is using it for the wifi card because whenever i have it hooked up to the computer, windows tells me i only have 1.99 gigs of ram available. I also know the card works because I've hooked it up to my brother's rig and he has windows vista 64-bit and it works fine with no memory being dedicated for it. I also notice when the card is connected my computer seems to hang doing just about anything even something as simple as just moving the mouse. So any help with this would be much appreciated as it has me baffled so far. I'll List a few specs below and i can always provide more if necessary.

I've already tried updating to the latest drivers and that hasn't helped at all. I also had this problem with a linksys wmp600n adapter as well.

Did ipconfig /release - /renew and restarted laptop just in case. The output is still the same and I can see in my taskbar wifi icon instead of LAN:

and cmd output also shows the same metrics as it was before changes were made?:

I have tried every PCI slot and have the problem in all slots (I reset BIOS each time). I have confirmed there is no IRQ issues. I have even disabled all on board perripherals (sound, FDD, USB ports, etc.) and problem still present.

Is this network card just not compatible with the Gigabyte MB or is there something else I can try before replacing the network card? Both FA311 cards worked fine on older version Gigabyte MB's. Since I have the problem with BIOS, I assume the OS isn't applicable (XP). I have the latest version BIOS installed on the MB (F6). Any idea's? Please let me know and Thanks!

Hi guys,

I will try and explain my situation as clearly as possible from the get go so there isn't a ton of probing questions that need to be asked.

My computer specs are:
Operating System: Windows 7 Ultimate 64-Bit (6.1, Build 7601)
System Manufacturer: Gigabyte Technology Co., Ltd.
System Model: GA-770TA-UD3
BIOS: Award Modular BIOS v6.00PG
Processor: AMD Phenom(tm) II X4 955 Processor (4 CPUs), ~3.2GHz
Memory: 4096MB RAM
Display: ATI Radeon 5670, 2805MB
Network Card: D-Link Xtreme N Desktop PCI Adapter DWA-552 w/ latest driver v. 1.70

My Situation:
Right now, everything works great. But, every time I restart my PC; my network card wont connect to the router. The SSID is displayed with full bars, however when I try to connect I recieve "limited connectivity" and get the error
"Windows is unable to connect" - http://img14.imageshack.us/img14/6835/step1h.jpg

From here I need to re-install my network card.

Here's the weird part:
As I'm uninstalling the network card, my connection is quickly restored to perfect functionality for 5-10 seconds until the un-installation completes. When I re-install everything it works great... until I reboot my PC.

Side note:
- When I formatted my computer, this issue wasn't happening. I began installing all my windows updates then it started again.

This makes me wonder if there's a Windows Update that is interfering with your network card driver. It's a pain, but you could start uninstalling the networking-related updates one-by-one ("Programs and Features/View Installed Updates") (reboot after uninstalling each one to check the issue). If it's an update, the issue will be resolved after you've uninstalled the right one(s). Or you could format/reinstall again and then update one-by-one, rebooting in between each, and see which one breaks it and uninstall that one.

Caps lock and Num lock reversed

On my new Gateway ML6720, the caps lock and num lock are OFF, but my caps lock and num lock lights are on. And vice versa. I don't remember it being that way this morning when I first turned it on.

Why are the lights reversed from what I expected?

I discovered this forum recently and it seems to be a good place to seek advice. So here is my problem:

I installed Windows 7 on a Dell Inspiron 530.

After a reboot everything works fine until I put the computer to sleep.

After resuming from sleep the cpu usage is extremely high even when the computer should be idle. Task Manager shows that the System (PID 4) process is using some cpu. Resource Monitor shows that a lot of time is spent in System Interrupts - Deferred Procedure Calls and Interrupt Service Routines.

My conclusions at this time is that the integrated network card (Intel 82562V-2) does not properly resume from sleep and creates a lot of system interrupts. Note that disabling the network card makes the problem go away right away, and the problem comes back right away after re-enabling it.

Tried upgrading BIOS of computer and driver of network card but that did not help.

Any suggestions? Somebody else tried Windows 7 on a Inspiron 530?

i have just set up a physcial server using server 2012 and i am running a few virtual machines on it using hyper v the issue the vms are all joined to the domain, however the issue i am having is when i log into these virtual machines they take forever to log in i belive this is due to the fact the dhcp is still coming from my superhub.

What i did i was i turned off my dhcp on the superhub and set up the dhcp on the server but after doing that my wireless devices at home did not connect where have i gone wrong

Also my server is not always going to be on so is it possible to have 2 dhcp servers on a network.
The dhcp on the superhub will serve the wireless devices and one physcial desktop
and the dhcp server on the server can serve the vms?

Unless you have some sort of layer 2 isolation between the two DHCP servers (either through having them physically separate or through logical isolation--VLAN), you cannot have two DHCP servers operating on the same layer 2 network.

Hi Gurus

Today I saw a peculiar problem in our network.

We are following DHCP based IP addressing for all the systems and we also follow VLAN based networking.

Few systems in a particular VLAN say VLAN 192.168.11.x was showing a different IP address as gateway, DHCP server etc and was unable to connect to network.

The IP was This system what I found was a ordinary XP machine in our network.

There is no alternate DHCP server running in that machine.

Then why some systems took this machines IP as the gateway, DHCP address etc...

But when I disabled and enabled the NIC card or released and renewed the IP , correct IP for gateway etc.were assigned and the systems started to connect to network..

Can anybody say where is the problem?

One of my officemates asked me to try fix her laptop because she was the only one who can't connect to our office router (wireless). Her unit is an HP-pavilion dv4-111 4nr entertainment notebook pc operating on windows vista home premium.

As I browsed on her unit, I saw that her DHCP client is turned off, and I believe that is the reason why her laptop computer cannot connect to the office router. I already tried checking the TCP/IP setting and check the "automatically obtain address" option on both ipv4 and ipv6 but still nothing happened.

How can I turn the DHCP on? I already tried searching through the internet for various solutions to the issue but none of the results I found gave a direct answer on how to simply turn on the DHCP.

Hoping someone can help me out on this one.

Thanks in advance.

A:Ongoing issue with apparent rootkit and/or virus attached to network card

I don't mean to "bump" this but since I've posted this message some other strange things have been happening that I really think is important for the person who hopefully is able to help me out with this issue.
1. When I go to virustotal.com to upload a file to check for potential virus's and click "upload" in firefox, upon browsing to c:\windows\system32\drivers, only 2 files are listed!  All the other files in this directory are missing. I've tried starting the browser and administrator, I've tried typing in *.* <enter> to make sure, and nothing.  When I browse to this same directory in windows explorer, all the files are there.  Even when I just blindly type the path to a file in this directory that is there, it does not see it or find it in firefox. 
2. I have had strange things dealing with "Hewlett packard" pop up from time to time. My computer is a dell. My daughter has a very old hewlett packard in her room though.  I never did clean her computer after my initial rootkit.
3. One of the most telling signs oddly enough of my original rootkit that I found in my network card was that my wireless mouse would every so often twitch and do curly motions without me doing antyhing but just move it.  This went away but now it is back.  The rootkit that tdskiller wound up finding originally was called:
c:\program files\broadcom\\MgmtAgent\brcmMgmtAgent and

I recently reformatted my computer and reinstalled Vista to it. I installed all the necessary drivers etc. and rebooted. But it still says "You are not connected to any networks" when the light on my router says that i am connected to the home network. It keeps saying to insert a network cable.
In the devices manager, the network card driver seems to be functioning normally.

Is there a fix for this?

The network card is a Realtek RTL 8111C on-board chip.

Also, ive read somewhere else that USB & 1394 drivers having conflicting effects with lan drivers. I installed an "Intel INF Configuration patch" which contained a crapload of USB Drivers which supposedly "configured properly" the intel motherboard chipsets, but im not so sure about that.

IEEE 802.11b and IEEE 802.11g,her linksys router is about same age too and am sure they both need updating, especially as she is moving to area where broadband speed check shows it will be even slower than where she lives now...

Question is :-

Can I upgrade to IEEE 802.11n, and if so, do I have to change the old internal card, or can I buy and insert an external network card adaptor, and then change BIOS settings to disable internal one and enable new one.Just want easiest solution please.
Will also upgrade her router.

I am currently using a Motorola SBG900 Wireless Cable Gateway Modem. As of two days ago, my internet would have issues with obtaining a DHCP lease. Right as the the lease ended I would lose connection for a minute or two until the connection would pick the IP address/lease up.

Now the DHCP lease renewal time was set to 1 hour, but seeing how being DC'ed every hour can interupt my online gaming I changed it to 99,999 seconds (max time). I don't know the consequence of my actions yet (if there are anything.), but the moral of the story is that I need a solution.

I've disabled KIS and gonna see if the other computers on the network are affected also, but so far I can only pinpoint the problem to the DHCP lease renewal. Shouldn't the connection be able to renew without dropping the connection?

So, I am not sure where to start, but I guess I'll start from what I am trying to accomplish. We currently have two ADSL lines at our office and just received our new phone system which are Polycom VoIP phones. It is a hosted solution. With our two ADSL lines, I want to use one for data and one for the voice. We currently have the the data line hooked to a VPN firewall and our Cisco switch is hooked to the firewall. I am only using 9 ports and my 9th is plugged in to our EdgeWater device, the VoIP router, which is plugged to the second ADSL line.

I set up a VLAN for the voice traffic to flow out of port 9, to what I thought worked anyways. I used MAC Address Grouping and Grouping to VLAN to do so. When I hook the phone up, it immediately receives an DHCP address and works perfectly. Problem is, when I assign the VLAN ID to the phone, it can no longer retrieve a DHCP address.

Ideas on what is causing the issue?

A:VLANs - DHCP Issue

Is your Cisco switch an actual Cisco switch or a Linksys switch? If it is a Cisco switch, what model switch is it? I am not familiar with MAC Address Grouping and Grouping to VLAN nor see how this applies to a VoIP configuration. The standard setup I've seen is to setup a voice port configuration on the switch called a multi-VLAN access port (MVAP.) In the configuration you set up a configuration assigning the port to a data VLAN as a normal access port. Traffic egressing from the port under this VLAN are non tagged. You then add a voice configuration to the same port which states VoIP traffic is going to be riding over a designated voice VLAN. Traffic eggressing from the port would be 802.1q tagged. This creates a pseudo trunk setup which allows a port to carry both types of traffic without being a full up trunk port. The VoIP phone is plugged into this port which now allows normal data communication to be broken out at the phone (if the VoIP phone is equipped with a data port. This helps shrink the number of drops needed at each desk as the person's PC would be plugged into the data port on the VoIP phone.

One night my desktop just couldn't connect to the network via wired LAN. Yellow warning sign with no internet connectivity, 169.254.xxx.xxx windows automatic IP, cannot get IP from DHCP. Here's some info:

- I used a pci wireless adapter on the same computer and connects to the network fine.
- All other computers connected to the network via wireless fine.
- Used the same port and cable and connected to another computer, connects just fine (not a cable issue or router issue)
- Used ipconfig, reset router/modem, deleted and reinstalled NIC, disabled NIC and restarted NIC, restarted DHCP in services, did Winsock reset, manually assigned an IP, system restored, in depth antivirus/spyware scan, updated every networking associated device/software. None of these methods worked.
Here is what temporarily worked.....

I used the same cable/port connected to the router via wired LAN to another computer which detects network and connects just fine. Right after, I plug it back into my main computer and it finally detects the network and connects to the internet. This only works when I have a manually assigned IP so it won't get the 169.254.xxx.xxx. However after awhile, it goes back to the same issue again and cannot detect the network or has no internet connectivity. That happens randomly. I would have to redo this process everytime in order to get it working.

Anyone have any ideas or how to fix this permanently?
