guess wireless network dhcp and vlan

Q: guess wireless network dhcp and vlan

So I have a small business I do IT work for. They are using Engenius WAPs for wireless which support multiple SSIDs and VLAN. DHCP is handed out by a Win2K8R2 server.

Now they want to set up a guest wireless network that only has access to internet and none of their internal resources. Problem is they need connectivity to the DHCP server. They have all dumb switches that don't support VLAN tagging.

I haven't worked much with VLANs, but I understand the concept and I'm trying to figure out if there is a way to provide what they wish (which is pretty straightfoward) without either

a. having to change the WAPs for something that have built in DHCP (that can be enabled on a per SSID basis) or
b. replace the dumb switches with switches that support VLANs

Any advice greatly appreciated. Thanks!

I have part of a network:
4 vlans configured on 1 switch(cisco 2960) which is connected to fa0/1 of a Cisco 2811router.
The server happens to be on the last of the four vlans (vlan40).
My problem is that its failing to provide ip addresses via dhcp to the PCs that are on the same vlan with it.
Thank You in advance.

We are implementing a new WiFi system here at work and I am having issues creating a new VLAN on my router that goes to my onprem DHCP server. I have verified already that my new Meraki APs are working with my RADIUS server when I tag the SSID with my current VLAN that works. I have attached my router config as well as 1 of my network closets. What is missing?

I also have to work with a 3rd party because the router is managed by them. Any help would be appreciated. I believe the DHCP server is fine because I just added another IP range in the same subnet.

Dear Sir,

Pls take a look the description as below:

Cisco Equipment
2 x 3560 switchs (Core Switch)
4 x 2960 switchs

- VLAN10 (server vlan)
- VLAN20 (User vlan)
- VLAN60 (Wireless vlan)

In the second vlan, a DHCP relay is setup on switch in order to redirect DHCP request to DHCP server that is located in VLAN10.

I have 6 cisco switchs and setup 3 VLANs on it. Now, I want to add one more dhcp server IP address to the user vlan for redundant's use in case of the current dhcp server broken down, as I am not familiar with cisco command, can anyone provide the code as:

1. What is the command to show current IP helper-address?
2. What is the command to add one more DHCP server IP address to VLAN20 for redundancy?

Dear All,

Iím having some problems with my Wireless network.
Iím struggling to get my wireless devices to connect to my wireless network. The only way I can seem to do it, is by assigning them an IP address manually Ė otherwise they get given a 169.xxx.xxx.xxx number.
Ideally, I want the devises to get the IP address automatically.

Look at the diagram to see my network.

Itís not a secure network Ė I havenít given the Wireless Router any Mac Addresses. I live in a very remote area, so Iím not bothered about security until I have it all working.

The wireless Router has 4 Earthnet Ports and 1 ĎInternetí Port.

My ADSL Router has all my Internet settings
(Both are Netgear)

My question is: How do I get my Wireless devices to collect automatic IP addresses?

Hope you can help.

I am really suck with my network. I live in a shared house and the landlord seems to have no idea so I'm having to take control, though as you'll quickly notice I dont have much clue either.

We have a Virgin internet router downstairs, provided by thembut the wireless signal hardly passes the room, so there is a cat 5e cable through the wall, upstairs to a router that I have installed DD-WRT on, that we then intend everyone to connect to wirelessly, though some are wired.

I have put the cable from the Virgin box into the Linksys normal bit (not the one that you usually put the internet one in), but I have no idea what to do now. I've tried searching but all I can find is if I was picking up the internet wirelessly, but it its wired. A few things seem to mention DHCP though.

Any help would be amazing please. If you dont have time to write how, or point me in the right direction, then just the name of what I'm trying to do would be much appreciated, but any help would be great.

Thanks a lot,

Hello, I have been experiencing some problems on my home network. I have problems with AOL, FTP and steam online games like counterstrike, team fortress 2, and day of defeat. I get these problems about 3/4 of the time, and 1/4 these programs will work.

When I sign into AOL I get a message saying "Could not connect to authentication server:

I'm definitely not a networking expert but I now wish I was. I have to create a vlan for some external equipment to use our network and they need specific ip addresses. The switches are Netgear FSM's which do apparently support managed vlans (I think that's important). I think I can set up a vlan but cannot see what the iprange will be for them to connect to. Maybe I'm totally confused. Can anyone help or advise me where to look for help? I have the manuals from the switches but they seem to make little sense to me.

A:vlan ipranges question for vlan newbie

Read other 10 answers

I currently have a network that has pretty much grown as required, and now I'd like to add some partitioning and management capability.

I've been discussing VLAN capability with zx10guy behind the scenes, and I thought I'd just jump out here and see if anyone has anything to add.

Right now, everything works and all machines and other IP devices are on a common subnet. The goal is to segregate the network so that some of the resources are protected while still allowing management and access to the whole network from a common point. Since this is my personal money, a major issue is the cost of doing this. Obviously, the switches will have to be changed to managed switches at the least.

Since I'd like some flexibility in managing the network, I'd like to do this with dynamic VLAN technology that controls access by MAC address rather than physical connection. I'm not entirely sure that this is practical given my cost constraints. I don't necessarily want all the workstations in a given location on the same VLAN.

Another goal is to allow at least one of the workstations access to the entire network to perform a management function. Again, I'm not sure exactly how I'll accomplish this across the VLAN boundary.

Another wrinkle is there are a group of NDAS disks that don't use TCP/IP for communication, and I'm not sure how the VLAN capability deals with that issue.

The switch family that seems to fit within my budget is the... Read more

I need to split a client's current LAN into 2 LANs so that the staff's office computers and devices are not accessible to the residents/guests. They currently have a modem+router device that gets it's public IP via DHCP, a couple of switches and a wireless access point that both staff and residents connect to (same SSID). The catch is they don't have static public IPs and the modem+router device MUST keep the current LAN IP network schema ( or the ISP won't provide technical support.

Hi and Welcome to TSG!

Many people have concerns about this, but it is hard for your access key to be cracked, although If you want to check there should be a menu called wireless settings, and in there should be a wireless access list, where you can grant access to MAC addresses commonly called mac filtering I believe.

There is also a link called attached devices, which should list all the devices connected, including name, MAC address, Internal IP, and operating System.

I am adding a wireless router to my network, and I don't know if I am supposed to enable or disable the wireless DHCP?

My network accesses the network through a DSL modem. Attached to the modem is my router, which acts as the network's DHCP server. There are about 50 computers connected to it, all wired.

But now I'm adding a wireless router to a part of the network. In the configuration page of the wireless router I can enable/disable it's LAN DHCP server and enable/disable it's WLAN DHCP server. I know that the LAN DHCP server should be disabled, because I already have a DHCP server on the LAN. But do I need to enable the WLAN DHCP server to get wireless to work?

I ask because, to play it safe, I disabled the wireless DHCP server. But my wireless computer, when it connects, fails to get a dynamic IP address.

Thank you for looking.

I have a wired client server network, and I want to implement wireless access. Currently, the network is a mess. The network consists of a single server and multiple hubs setup around the building that then connect to the ports in each room, the typical setup. Wireless setup has been attempted by placing wireless routers throughout the building, but by no means have they been properly configured. The routers' DHCP servers have been left on and are now creating problems because they are trying to assign IP's to the wired connection. I assume by turning off the routers' DHCP server that the server should take over, but then it appears that the wireless computers can't establish an IP. The routers being used are mostly Linksys, and there are a few D-Link. Is it okay to use a normal home network router? What is the correct way to configure the router so that it merely broadcast a wireless signal and doesn't conflict with the DHCP server? Would access points make more sense? If you haven't deduced yet, I am not in charge of the network I am just the one looked to to find the problem. The person who is in charge knows very little besides what they have learned in a few classes and they are hardly ever around. I myself know only basic networking. That meaning not much more than what you learn for A+ certification and from home and small network experience. Any help or suggestions that could set me on the right track would be much appreciated.

One a few rare occasions due to interference or power outages my wireless broadband connection from my ISP will go down. As a result my Mandrake 10 firewall it will loose it's DHCP address and I will have to manually down and re-up the eth0 to get connected again.

What I would like to do is to run a cron statement that will test to see if I have an active connection to my ISP's gateway (doing like a ping request) and if not then asume that the connection has failed and have it down & re-up the eth0 port automatically. Maybe this script should then sleep for 30 seconds and re-test for an active connection, if active then exit otherwise repeat the process again.

I'm having problems figuring out a good way to test for an active connection. Does anyone know of a good script command(s) I can use to ping the gateway for the test part of this script?

Hi all

Got another Vista wireless networking problem.

Running Vista Business and connecting to a 3Com Officeconnect wireless router - this is set as a DHCP server with a pool of 5 addresses - MAC address filtering and WEP are enabled.
We also have another DHCP server on the same subnet (not a great idea I know but the boss's decision unfortunately)

When I connect to the 3Com, although it connects successfully, it uses the other DHCP server to assign a valid IP but doesn't assign DNS settings. Both can assign these ok, tested with XP.

I would have thought that this was the other DHCP answering before the router if it assigned the full details but it doesn't assign the DNS or gateway.
I tried using the TIDs from MS to adjust the broadcast flag to see if it was an issue with the type of router but makes no difference. Have also tried other KB articles and changed the values for the DHCP in the registry (changes back to the incorrect one once connected)

Things I've tried with no success:

Recreate the connection
Manually assigning an IP etc works ok
Disabled MAC filtering and encryption - same results.
Disabled IPv6
Changed Broadcast flag
Manually edited details in registry
Release/renew/flush ipconfig
Searched here and other places for solutions and tried most....

We have a new EFM service, which is connected to a RAD Network termination Unit; in turn this is connected to a Cisco 887VAM router, which in turn is connected to a TP-Link TL-SG1024 switch.
I can connect any computer to the switch and can connect to the internet as long as I assign each one of the 5 static IP addresses I have.
How do I get it so that I can connect more computer and have them detect a generated IP address?
I gather this is to do with DHCP at the router but I don't know where to start.

Any help?

I'm getting really annoyed with this boot delay I'm having. Ever since I installed my linksys wireless card, at windows boot there is about a minute delay after the GUI comes up, and then finally the wireless adapter utility loads in the systray, along with antivirus and other things.
I thought maybe a new card would help, so I got a different brand and have the exact same problem. I expect windowsxp is being dumb and trying to contact a DHCP, before it even loads the necessary wireless utility for connecting wirelessly. Can anyone recommend a solution?

A:XP slow boot with wireless card, DHCP?

It is likely searching for a IP address . . I leave my card out of the notebook unless I am connecting to a wireless network . . starts much faster. If I need it later, I insert it and let it find a network.

It's take time to connect wireless thru ADSL DHCP... you need to release and renew.. the IPCONFIG

is there any way to connect immediately?

A:Solved: HELP: It's take time to connect wireless thru DHCP

With absolutely no information about the environment, it's really hard to answer.
Please supply the following info, exact make and models of the equipment please.

Name of your ISP (Internet Service Provider).
Make and exact model of the broadband modem.
Make and exact model and hardware version of the router (if a separate unit).
Model numbers can usually be obtained from the label on the device.
Connection type, wired or wireless.
If wireless, encryption used, (none, WEP, WPA, or WPA2)
Version and patch level of Windows on all affected machines, i.e. XP (Home or Pro), SP1-SP2-SP3, Vista (Home, Business, Ultimate), etc.
The Internet Browser in use, IE, Firefox, Opera, etc.

Please give an exact description of your problem symptoms, including the exact text of any error messages.

If you're using a wireless connection, have you tried a direct connection with a cable to see if that changes the symptoms?
For wireless issues, have you disabled all encryption on the router to see if you can connect that way?
Have you connected directly to the broadband modem to see if this is a router or modem/ISP issue?
If there are other computers on the same network, are they experiencing the same issue, or do they function normally?

On any affected computer, I'd also like to see this:

Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

Type the following commands on separate lines, following each one with the Enter ke... Read more

I am replacing a defective Netgear router that was working in this same configuration for years. I am replacing it with a TrendNet TEW-731BR (N300 WiFi Router). This router will be used without WAN connection at all - just purely as a wireless AP with the intent that it passes everything through the LAN port to the "parent/master/A" router which has DHCP activated and has access to the internet.

Quick summary:
Master - (DHCP is to
New TrendNet - (DHCP disabled)

My configuration is a straightforward LAN-to-LAN, same-network type of cascade:
(start disconnected from everything - just connect via wifi to the TrendNet router)
* factory reset the TrendNet router
* Go to the setup page and...
** disable DHCP
** set the static IP address to an unused IP address outside the DHCP range of the master
** change admin password
** set SSID and wifi password, change security to WPA/WPA2 AES
(now connect the TrendNet, newly configured, to the master router LAN to LAN. WAN is not used at all.)

The computer I was using for configuration now works great. Full internet access, able to ping/access anything on my intranet, etc.

Any other device hangs on access and ultimately says it couldn't get an IP address. If I set up a static IP address then I can connect with the other devices.

It's as if the TrendNet router doesn't know to hand the DHCP request over the LAN port.

I confirmed multiple times that "WiFi is... Read more

I've got a Netgear WG102 connected to a Netgear FVS114 Firewall as a DHCP server, that's then connected to a crappy BT Voyager 102 ethernet ADSL modem.

I can connect to the network fine, and it works for a while, but will then stop transfering data, and I can't get a new IP - a /renew gives me an autoconfigured address of

Even when it doesn work, it won't do bizarre things like copy emails to my IMAP sent folder, even though it will send the emails and allow me to view new ones, even when there's no firewall turned on. This could be an internet issue, but the DHCP issue can't be.

Any ideas?

I have an active directory, a DHCP server, 3 VLANs, and 2 wireless Router/AP/Repeater. I was thinking, might be the first problem, that I would put in one as an AP and one as a Repeater. The signal is there and static IP on the device works, but that is, well, it does not work for what we need it to. I tried enabling DCHP on AP but it is assigning ips to our voip phones. Really messes them up with they use get connected that way instead of the DHCP server.

So I am not sure how to set this up where a device connects to the wireless, get assigned an IP from the DHCP server and works.

I have tried several different ways, but have not hit what works.

Good Evening,

I'm having a problem with my laptop. I recently removed some spyware and now when i reboot, i have to manually start the wireless zero configuration & DHCP Client service manually. These are some of the things i've tried to fix the problem:

1.Made sure i didn't have another wireless device that's trying to manage my wireless connections.
2.Went into the network connection properties & under the wireless networks tab, made sure the "use windows to configure my wireless network settings
3. went into windows services and made sure DHCP Client & Wireless zero were set to start automatically (& started)

After i reboot, i have to manually start it all over again. I've been all over the net trying to find answers and suggestions & nothing seems to work. Any help would be greatly appreciated. I'm using Windows XP SP3.

okay, recently my old dlink wireless network adapter started spazzing out on me (it was sucking my amd4200 dry with hardware intterupts) and i had to replace it with a newer version. After many hours of aggravation b/c WZC not working like it should i used the the software that came with the cd. it worked fine and connected to my router but wont aquirre the address. i narrowed it down to be the DHCP client not starting correctly. In the services it says starting but never actually starts and all the options are greyed out so i cant tell it to restart. i need to know if anyone knows how or if i can resintall the DHCP client. without actually reinstalling all of windows. anyhelp will be apprieceted.

Network Config/Topology:
1x WinXP Pro Desktop (Gateway PC) with dial-up PCI Card ( U.S. Robotics USR5610B)
1x Win2000 Desktop ("Client" PC) connected via cat5 cable (at first crossover then patch)
1x WinXP Pro Laptop ("Client" PC) connected via wireless.

Basically I've ran a cat5 crossover cable to the computer next to me (Win2000Pro), I easily configured ICS to work on that computer, and all went well until I bought a laptop. Once I got the laptop, I wanted to, of course, have it available to access my dial-up connection (so I could be in other rooms within the house and still access the internet on the amazingly slow speeds of dial-up since it's the only thing available here). Basically after a while, I decided to switch the ICS over to my newly purchased Linksys Wireless G PCI card and setup an ad-hoc network...that worked too, but the only problem was that the "client" desktop could no longer access the internet through the Windows XP Gateway since you can't bridge ICS (at least I've never been able to get it to be a success). So, I setup AnalogX's Proxy program and configured the computer to work as such. But, that gets old after a while when you're limited to certain ports, etc...so, I went out and bought a D-Link DI-524 Wireless Router so I could have both my connections going to the same ethernet port on my computer so ICS would work. I first thought it was because of the router and my misconfiguration...but... Read more

A:Dial-Up ICS using Wireless Router with DHCP Failure

Basically, to simplify this question, does anyone know of a way to reset and fix ICS, especially the DHCP server hosted? It's not transmitting IP addresses and not picking up the address under 192.168.0.xxx. To my understanding, even though I set it up as static on my other "client" ( and on this gateway (set to, it should still work and be picked up. What's causing the problem? Any help would be greatly appreciated.
