DHCP Issue?

[millshre]

I have one Wireless Machine that seems to having an issue getting an IP Address from the DHCP.

 

Background:

 

Our DHCP scope ran out of wireless IP addresses. I tried to Supernet to get us more. DHCP started to hand out from the new Supernet, but they could not get internet access. I tried to change the access lists to allow this. That didn't work so I gave up for now, and tried to put things back to where they were. I rebooted the router so it went back to the Startup config, recreated the original scope. All of the devices on wireless started getting appropriate IP address, and the Wireless is working fine again.

 

Problem:

 

One Windows 7 machine will not get an IP address from the DHCP. I get this from ipconfig /all:

I tried resetting the DHCP service on the server, no luck there. It can get an IP Address just fine from a wired connection, it only it has trouble with Wireless. I have tried netsh winsock reset, netsh int ipv4 reset, netsh int ipv6 reset, ipconfig /flushdns, ipconfig /release, ipconfig /renew. I have tried turning off the DHCP service on the client. No luck. Not really sure what this issue is.

I had something like this and changed out the wifi card and everything worked again.

 

Tested the faulty wifi card in another machine and got the same results. Possibly try another wifi card.
