Wifi DHCP - the second network card on a fixed IP

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

I warmly welcome

I have a problem with configuring network cards

WIFI comes nicely with DHCP pool 192.168.0 .*
but

I have a virtual network adapter "Microsoft Loopback Adapter"
in it I have to have a static IP address 2.0.0.5
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

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.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

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

I quote (from ):






Quote:
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.

Hi All,

I have read through a lot of other posts but can't find a solution related to my issue.

I have a Dell XPS laptop with Windows 7 Ultimate I want to use for bridging the Ethernet connection to it's WiFi connection. WiFi connects perfectly to the net. I enabled ICS on the WiFi and then bridged the WiFi and Ethernet connections.

WiFi still connects to the net fine on the XPS, but when I connected another PC to the laptop via Ethernet, it only shows a 169.254.116.152 IP address on the PC and throws a Network Error "Windows has detected an IP address conflict." It looks like for some reason DHCP on the XPS is not assigning an IP to the PC to bridge the Ethernet connection to the WiFi on the XPS.

When I do "ipconfig /renew" on the PC it says "An error occurred while renewing interface local area connection... The DHCP client has obtained an IP Address that is already in use on the network... "

I am a fairly technical person having built computers and network for the last 20 years, I've been trying multiple solutions for hours and reading everything I can, but this one has me stumped.

Thanks in advance for any assistance

Hello Everyone,

We our setting up a Training Company to assist unemployed IT people in the Silicon Valley area of California. Our group is very small and having a hard time even getting our network here started. Here is the problem: We have Windows 2003 Server Enterprise 180-day usage disc (from a book we bought to learn). We have 5 static IP addresses leased from DSL carrier. They are for example: 65.123.141.10 thru 65.123.141.14 with a gateway of 65.123.141.9 [these are only IP numbers used for example to prevent hacking] my subnet mask is 255.255.255.248 We tried and tried for 2 weeks now and still can not get the complete network to work. We need: Step1.) The server to be secure with a firewall (but willing to forgo that and add later) Step2.) the server to issue Ip addresses from a pool of 192.168.0.10 thru 12 to 3 workstations running XP(we decided to make the server 192.168.0.5, subnet mask is 255.255.255.0 and gateway 192.168.0.1 Step3.) Have access to the internet on all workstations and the server too. All we have succeeded to do is get the dhcp to issue out addressses to the workstations and even that i think we got lucky. We think the problem is somewhere you need to tell the (maybe iprouting?) setup that the Public ip address is the 65.123.141.10 and gateway, subnet info and to route to the server PRIVATE ip address 192.168.0.5

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.

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 127.0.0.1, 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.

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 can’t 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 ... Read more

I have access to an ftp server via guildftpd (as suggested in this thread http://forums.techguy.org/t273868.html ) and has been working very well. However, he has had to change ISP's and routers.
Previously he had the PC with guildftpd connected via a router but the ISP provided 5 fixed IP for him to use.
Now he has dhcp for his PC's, and the isp does not supply fixed IP's

we have looked at portforward and think that all we need to do is give his PC with guildftpd one of the top range IP as a fixed IP, and forward port21 to that IP - but not sure how this will work with dhcp on the router as we do not seem to be able to switch dhcp off or have a fixed range of IP's

Working on Win7 Pro x64 for years with same network settings - gigabit wired IPv4, fixed IP, fixed DNS, etc. Lot of other comps, network printers, APs - everything works fine. Suddenly last week my machine (only one) refused to connect - sometimes with yellow exclamation triangle on network icon, sometimes w/o it. But even if it tells "connected to internet" it does not connect to anything, even gateway. Few times it was resolved by reconnecting network cable. Trying various solutions without success. Then I noticed, that changing IP settings to DHCP solves problem - connection is back. Reverting to old fixed IP "disables" connection. I didn't install any new hardware or soft, only periodical software updates. Restoring system from "working" image made nothing. Have no idea - what's going on? Any way to fix or check what is a cause?

A:Can't connect with fixed IP, only DHCP works

As strange as it may sound, some Access Points (AP/router combo) will not allow devices with static IP addresses to connect* if the IP address of the device is outside of the DHCP range. They claim it is a security feature. The AP/router can tie the IP address to a MAC address - thus making it like a static IP assignment - but within the DHCP range. That IP won't be assigned to any other device.

*connect can mean different things. The computer is in the router's list of connected devices, but the computer is not allowed to connect to the internet or any local network assets.
I mention the above info so that I can ask if the firmware in the network device handling DHCP might have automatically updated and started enforcing that type of "security". Or, perhaps the DHCP range got changed and this one computer is now outside of the DHCP range.

Also, what happens if you assign the problematic computer a different static IP address?

Hi,
I hope someone can help me with this.
I want to setup a wireless router on a network with around 40 pc's (winxp pro) and 4 existing routers.
I'm running server2003sp2.
I've got most of the wireless stuff worked out until I get to connecting to the DHCP.
I think I have to use a fixed IP address and enter the subnet mask.
No problem so far.
I'm confident I can work out how to find where my address range is stored within the DHCP on the server.
What I'm not certain about is how I find out what the address's are that already have been fixed (i.e. ones I shouldn't touch ).

Does anyone know how to query the server to get it to divulge what address's are fixed and which are available on a win2k3 server?
I thought this wouldn't be hard but somebody I respect has told me that there is no way to find out from the server.
Anyone with more knowledge?

Regards
Matt

Hi there, I recently installed Windows 10 on my desktop which was previously running Linux Mint (without issues with networking, using the same router, same cable same everything). Since installation W10, when I boot up I get the 169.x.x.x IP, meaning my pc isn't receiving the IP. When I do a soft reboot on router, my PC gets an IP from DHCP fine. The DHCP pool is big enough and I don't have this issue over Wi-Fi with any of my devices (laptop, phones) nor did I have this issue when I was running Linux mint.

I need some trouble shooting tips to help me figure out whats wrong. First of all this is a Toshiba P755-S5120 laptop Windows 7 64 bit

I have been having trouble with a weak wifi signal and poor connectivity. Here is a test I did: My back bedroom is about 3 rooms away from my router in the back of the house. In my room I have this laptop I'll call #1 and another laptop also I'll call #2

Both laptops used to get full bars/excellent signal strength, now #1 has 3 bars and fair strength and very poor speed and connectivity while #2 still has a great signal and does great on speedtest.net getting 45-50 Mbps download which is great.

If I run the speed test on #1 it is variable from 3-20 Mbps download and sometimes looses connectivity and won't even complete the test. The problem has been getting worse over time.

If I take my lappy next to the router it is much improved but still doesn't get the speeds that it should. I also tried plugging in a network cable directly into the router (no wifi) and it still is impaired.

Do I need a new wifi card in my lappy? Would this effect it also when it's plugged in with a network cable?

P.S. I have already reinstalled the correct driver for the wifi and that did nothing for it

Hi, Iv'e been looking at a laptop recently - Dell Inspiron 1501 - At one stage it was picking up all the networks and now it won't pick up any. I have done many tests which says the wireless card is functioning normally and the WIFI indicater is swiched on (Fn + F2).

I have changed it from windows vista to XP and still the problem remains. I'm suspecting it would be that the radio signal is jamming somehow but I don't understand how it could happen.

Would it be something wrong with the network card even though all tests says that it is working properly?
Or could it be something like a driver or software that could be causing the issue even though I'm after switching the Operating Systems?

I would like to know before I go and purchase a new network card everything seems to be working fine only for the radio part of it.

Thanks in advance
 

A:WIFI - Network card

First, you need a way to verify the networks are available. You can't just assume a wireless network is available. So you need another PC or other hardware to verify the wireless network is working. Assuming it is working, the wireless card would appear to be faulty. As you've used two OS's, you've very likely ruled out an OS and driver issue.

I am working on a friends hp dv6338se which had a bad hard drive when he brought it to me which I replaced.

My friend tells me that it worked before the hard drive crashed though he was running windows vista. I have tried everything I can think of to get it to work. I even disconnected it and reconnected it and the computer still does not find the device. All the drivers are installed on the computer and doesn't show that any are missing. Under network adapters in the device manager it just shows the wired LAN card. I tried installing the broadcom driver and the HP wireless agent thinking it might make a difference but didnt. Should I assume that the card is bad and go after a new one? Or is there something that I am missing because I installed Windows 7 on it? He very much wants windows 7 and I would rather not reformat it and reinstall vista if it is not needed. Only thing I can think of is that it is a hardware issue. Any input would be greatly appreciated!

these are generally the series of hp laptops that had a manufacturing problem where the heat would separate the connections from the motherboard and you no longer have wireless internet ... or in some cases the computer would not boot up at all.

I'll explain quickly.

- I bought a D-Link DWA-547 Pci wifi card, believing my old card was dead. (I tried it on a older computer with XP it runs perfectly).
- I installed the new card, no problem.
- now the card is activated in the "network connections" tab (it is even green just like seeing a few wifi networks). but I cannot see any wifi networks, and there are a lot nearby.
- I have tried to unistall/reinstall my new card. no luck.
- I have connected myself to Internet by RJ-45 to put everything up-to-date, no luck.
- I have tried to desactivate/reactivate my card.
- i uninstall "bonjour" as I read somewhere this could be the problem. still no luck.

- furthermore, when activated when i'm using the command line ipconfig/all, the wifi card does not appear in this command line.
- I tried the ipconfig/renew it says "the operation has failed because no card has the autorised status for this operation" (i'm translating it from french, so maybe it's not the exact words).

maybe a clean install would be THE solution, but I really would try not to do that.

please help!!

Welcome to Seven Forums,

I'd verify from your computer's BIOS if LAN and WLAN support are both enabled.

Depending on the Model of your computer, when you retart it you may either select F1 or F2 to go the BIOS setup.

My wife got a HP17-g121 laptop and when trying to connect to our 5g dual band router I realized the adapter does not work with 5g and I want to replace it, what make and model will work best in doing so? Also, for some reason the 2.4g band will barely get me 25Mps download speeds where on my HP the 5g gets me closer to the 150Mps I am suppose to be getting, any reason for that?

Hi,

My computer has recently started to drop the WiFi connection, reconnect after a while and at times, not even detect my WiFi connection for a while. Then repeats the process for no apparent reason, I'm not sure when exactly thus problem started as I had been using Ethernet cable up until last week. I am certain that this is not related to my router as 3-4 other devices in my house can access the internet perfectly fine.

I have tried doing a power cycle of the router, restarting the notebook, re-installing/updating drivers and cmd ipocnfig /refresh (and other commands along those lines)

My notebook model is the hp pavilion 3132tx- windows 7 64bit, intel I7, 8gb ram and uses a ralink RT3090 network card.

Ps: the problem appears to be alright if I use older versions of the driver (have tried 3.1.18.0 and the default one which came with the notebook [which is older than it]) however, I would prefer not to have to use the older versions as task manager says that its link speed is only 39 mbps whereas versions 5.0.5.0+ would show 79 mbps

Thankyou in advance.

A:Notebook drops wifi connection randomly- Ralink network card

It sounds to me like a signal problem. A competing signal drowning out your wireless signal can cause these kinds of random losses.

To test for this try this program:
inSSIDer for Home – Discover The Wi-Fi Around You | MetaGeek
It will tell you if you have a stronger signal in your area that is interfering with the channel.

Debating on going wireless or not: Have an Asus M4A87TD EVO that has RTL8111E PCIe Gigabit LAN controller featuring AI NET2. So Gigabit, Im thinking at least 100/1000. I am wire into my router which puts out high speed and low ping to wireless. Standard Ethernet cables supply the data pipeline, not sure what the transfer speed is on them, If anyone can let me know that would be great.
I have been eyeballing the super speed ethernet cables, but not sure if it would solve the ping issues I have with desktop, (being too high), and the cost for a 15' line.
Tried finding a wireless card that handles N+network and 5.0Ghz for my dual band.

1. What is the standard ethernet cable speed?
2. Can the standard ethernet cable from router to computer be causing high ping? (have second computer with 3' cable, same issue)
3. Would it be better to go wireless and forego the wired ethernet cable?
4. What wireless card would you recommend?

A:Network speed and ethernet cable questions with wifi card question

UGH

1- what kind of cable? cat 5, cat5 E, cat 6?

2-Yes if cheap, old, or not shielded.

3-Not if you are transfering large amounts of data on your internal LAN

4-An 802.11 "N" card

I have a fairly old - 8 years - Internet radio (Magic Box is the brand) and I've not used it for a few months. When I tried to connect it to the network I got a message "DHCP failure or incorrect code". I am sure the code is correct - any idea what is meant by DHCP failure or how I could resolve it. I have a laptop and iPad working on the network without a problem. I tried switching both off as I thought it might be too many devices but still no radio connection. Thanks.

I recently upgraded two Dell laptops, (an XPS M1330 and XPS M1530), from Vista Home Premium to Windows 8 Pro.

Other than a few minor glitches, everything went pretty smooth except for both WLAN cards slowing from a fairly consistent WiFi speed of 270 Mbps down to 54 Mbps.

I have a Netgear WNDR3300 Router and it's working fine. After the installs, I could insert a USB Wireless-N Dual Band adapter in to either computer and get the 270 Mbps speeds back with no problem.

I pretty much gave up on finding a solution thinking that a driver update or something would eventually come along as a fix.

However, after reading that WEP is not the best way to secure a home WiFi network, this evening I decided to change the security setting on my router from WEP to WPA2-PSK [AES]. That change not only made my router and home network more secure, but also returned the faster 270 Mbps WiFi speeds!

I found various possible solutions (and tried a few), when originally researching this problem, but this is the one that worked for me. If you're here looking for a solution like I was a week ago, I highly recommend making this one of the possible fixes to consider.

Good luck!

Given that there will be no antenna inside the system for bluetooth, you're better off with one of these:

Hi there (again),

I'm having an issue with the Microsoft Virtual WiFi Adapter. Since I had to uninstall Connectify (it prevented my computer from entering standby or hibernation), I started to use the Virtual WiFi Function manually (netsh wlan start hostednetwork). It works absolutely wonderful with Windows 7 clients, it works well with Windows XP clients (slightly slower, but I guess that's normal), but it fails for my iPhone and other Apple mobile devices. I have no idea why, but I know that Connectify had the same issue and fixed it with version 2.0.
The iPhone connects to the network (showing a checkmark next to the network's name), but doesn't show the WiFi-Icon, and I cannot access the internet or local ressources.
This seems to be a DHCP problem, as manually setting an IP address, setting the Subnet to 255.255.255.0, and entering my laptop's IP-address as the Router and DNS server solves the problem (at least sometimes, it's not that reliable). But as I'm a perfectionist (and want others to be able to use my network), I really would like to see DHCP working there.

Is there anything that I could do to fix this problem?

Thank you so much for your help!
With kind regards,
Felix Freiberger

Hello, I have virtual wifi miniport active through nesth, I use it to share internet to my Nintendo 3ds but I can not share it with my Nintendo Ds, after reading and found that the virtual miniport wifi dhcp not active, I wonder if there is any way to enable the miniport dhcp, I have been sharing internet through mac OS x Snow Leopard but I work on both Windows and Mac OS, while I like to play while completing the build process.

Any help is truly appreciated.

A:Virtual Wifi Miniport, dhcp question.

You should be able to turn on DHCP the same way that you can on a regular NIC. Go to the Network and Sharing Center, then look left to "Change Adaptor Settings" and click that, highlight and right click the Virtual adaptor and choose properties, then right click TCP/IPv4, choose properties again, make sure that the upper dot is set to "Obtain an IP address Automatically, same for DNS.

I was having intermittent disruptions of my Wifi on my new XPS 13 in my bedroom.  The router is a Netgear N300.  Everything worked well at first then the interruptions started when I installed a usb port on the right side of the laptop.  It's a plastic port with no cord.  It swivels and plugs in with three extra ports above the laptop's usb port.
The 3 socket usb extension was in the right side usb port with a light and two additional devices plugged into the port.  The port"s usb sockets extend above the laptop's usb port and has a swivel feature.  After removing this usb extension and placing it on the laptop's left side,  the Wifi worked fine.  Apparently the usb extension on the right side was blocking the laptop's internal antenna.  I still use the laptop's right side usb port with one device and there's no problem now.
I did purchase a Wifi extender in the mean time but probably don't need it now........
