laptop wireless not working, wired is fine

I'm trying to get a Windows XP Home laptop to connect to the web wirelessly. The modem/router (leased from my DSL provider) gives me an address & other network settings fine. I can get to the modem/router & bring up it's configuration webpage, but that's all. I can't even ping my network printers ro PCs. Other wireless computers on the network have no problems. A wired connection works completely fine (web = OK). Here's a list of things I've tried:

netsh interface ip delete arpcache
netsh int ip reset /log.txt
netsh winsock reset catalog
ipconfig /flushdns
verified wireless hard switch is on
restarted dhcp, dns, windows zero configuration via services.msc
scanned for viruses
reinstalled wireless drivers
tried a known working wireless usb adapter - same issue
disabled firewalls
flushed IE8 browser (temp files, cookies, etc.)
reset IE8 to fresh install defaults
sfc /scannow
disabled windows zero configuration & used the Intel Proset Wireless software

Anyone have any other ideas? Thanks in advance!

 

Greetings, chiepler.

Looks like you've tried everything I would have suggested. The only other things I can offer are:

1. Make sure your proxy settings are clear.

2. Boot to a Linux distro (Mint is a good one), let Mint/Firefox try to access, see if you get a change in symptoms.

 

make sure SP3 is installed.

SP3 is installed.
The proxy setting is empty.
Didn't have to boot to a Linux distro....

I tried utilizing the procedure for virus removal as described at this site again (nothing to lose, right?). Turns out that is what seemed to fix it. I must have missed updating something the first time through. SAS & MBAM didn't show any threats removed, but maybe ComboFix, RootRepeal, or MGTools did enough this time. I can't really tell because I don't know what exactly they do behind the scenes - I just let them run.

Thanks for your replies!

 

Thank goodness for anti-malware utilities - where would we be without them?

Glad you got things sorted, chiepler, and thanks for the feedback. :major
