HELP! Laptop connects to routers but IP won't assign!!!!

[BillyBatson]

OK the laptop was running fine. It has a built in Intel wireless B card and a p-cmcia Belkin MiMo Pre-N card. Both running fine until adware was accidentally instaleld onto it. All the addware was removed using programs and the laptop rebooted. Once booting back in the net connection was gone. It is able to see and connect to wireless networks but it says "limited or no connectivity" due to not being assigned an IP addreess. We have tried 3 different wireless cards and on 2 diff networks with the SAME result, the computer refuses to be assigned an IP.
Yes we tried all the disable/enable, repair, cmd ipconfig/release/renew etc etc etc ! what could be the problem!?!?!?!? We also tried just a regular ol' 10/100 connection to the router and SAME thing.

It has been a week now like this and she is over right now so any help is GREATLY appreciated!!!!!!!!!!!!

Are you _sure_ you got rid of all the malware? You will want to run at least 3 or 4 different programs to clean a bad infection. A local antivirus, some of those online antivirus scans, Adaware, Spybot, etc...

Are you running the 'DHCP client' service? Check by going Start-->run-->'services.msc' and look through the list.

If thats running and it doesn't connect, try setting your IP manually.

If it still won't connect you might have to do a repair install.

Have you tried ?

netsh int ip reset reset.txt

The shell reset command might work. If not then dowload and run the XP winsock fix/patch. Google search will find it. Pretty common problem. TCP/IP stack corruption. Also the LSP2 fix might solve it as well
