DHCP gone mad?

Well hello there.

I recently changed my router to an "N" model with more speed, more range etc..

Everything works great except one thing. One of the computers on my network can't obtain an IP from the router..

Works on every other computer but not that on..

The router is set to work on both b/g/n/ so that shouldn't be any issue.

Well, help? :S

1 - How many IP addresses are in the DHCP pool on the router? I have mine set to give out only 4 addresses, but not sure if there is a default limit set on consumer routers that might need to be increased.

2 - The one pc that can't connect. How old is the card, and are you using anything like WPA2, etc with the router? Maybe something is not configured correctly on the one pc.

3 - Have you tried setting it manually instead of using DHCP? If it works manually, then just use it that way.

4 - How far is it from the router? Is there interference, walls, cordless phones, TV's etc near by? Try the card in one of the other computers and see if it works in them.

The card is a few years old but it should be able to get an IP.

Atm I'm using WPA-PSK since that encryption worked well on my

previous router. The router is set to hand out atleast 50-60 ips.

The computer is running WinXp with SP2.

I'll update the drivers for the card as soon as I get home.

And the router is running the most recent FW.

Ty for the responses, keep em commin!

A while ago I had to fix someones laptop that was doing a similar thing, turned out that they had set their firewall to block the ports for DHCP (67). So something else to check.

No fixed ip was set

No firewall issues

Most current driver installed

I've tried to set a static one with opendns

but I can't seem to get online.... Wtf

I'm considering weither the nic is outdated.

Might buy a new one if I can't solve this issue...

setting a static ip via opendns? DHCP does not equal DNS

Set the ip via the computer itself.

Go to the properties of the network connection

go to the properties of the "Internet Protocol"

Fill out the relevant info and apply.

This is how you can set the static ip

Your computer can not get to the internet if it does not have a ip. or know where the router ip is.

Also check to see if the router has a menu showing "connected devices" look for the mac address of the flaky computer. this will tell you if the computer is being stopped at wifi auth or just can not talking to the DHCP server (router)
