Ad Hoc Network Won't Go Away!

I am missing something in my troubleshooting.


HP laptop / XP  
The Wireless Utility (Windows and Broadcom) will only see an ad-hoc network. The icon is even different then Access point networks. I assumed that the user used the windows wireless network wizard and setup ICS. I spent sometime troubleshooting the settings, manually adding the Access Point, switching users, turning off ICS, ect. No luck.

I reset the wireless router (Westell VersaLink 327W) and made sure its broadcasting the SSID. The distance is 10 feet so I know it should be seen. It works fine with another laptop.

Next, I reloaded the OS and have had it working fine off Access Points in my office. Back onsite it was again seeing only the computer-to-computer (AD HOC) network. The site has two Dell Dimensions that are hard wired, the HP laptop, one Westell modem/router and printers.

Why after a reload is it only seeing the Ad-Hoc network?

It cant be laptop because it works fine in other site.

Cant be router because it works fine with other laptop.

Where is this network coming from (machine was formatted / reloaded so configurations should have been changed)?

WHAT AM I MISSING     lol

Not necessarily true. The wireless MAC of the laptop that can't/won't connect could be blocked in the router's firewall.
Reloading the OS wouldn't change the MAC (wireless or wired).

So you reset it to defaults and it's now broadcasting its serial number as the SSID. No WEP or WPA password is set in the router, and the MAC filtering is disabled. Is all that correct?

Hmmmm...  Did you shut down the devices one by one to see which one is advertising the ad-hoc network?
In the original query the only other 2 machines mentioned were hard wired.

Which specific model router is it, btw? According to Westell's site there are 9 different models of the 327W... it should give the complete model number on its barcode sticker.

In Network Connections, highlight the wireless adapter, right-click it and choose Properties. In the dialog that opens, choose the Wireless Networks tab. Click the Advanced button. Which option is checked there?

I have no idea why that netork was stuck even after I reloaded. But I finshed all the updates, went back the next day and it worked fine. The only other thing I did was turned off an HP printer with wireless cababilities. Weird. Thanks for your help.
