Cannot find any wireless networks

[sprockkets]

I was at a client yesterday, and one of his computers could not see his router. Yet, my laptop and his and his printer all connect to it just fine. The computer via the Windows or software from the Dell 1450 USB adapter, both say they cannot find anything.

Well, I said most likely the adapter went bad. I tested it at home, and works just fine. He then bought a new adapter and it also didn't work, thus the error must be in windows. My question then is, what part of windows needs to be fixed?

Oh, we also did try other usb ports and it went up to number 3 on the adapters.

before you try anything crazy reinstall the drivers.

seems simple enough, but wouldn't a completely new adapter fix the issue? Of course, he put it in and not me, but somehow I feel both are not seeing any networks for the same reason, not due to a signal issue.

May be this can Help.

My New Wireless does not work - http://www.ezlan.net/wireless.html

If the Wireless interface indicates that there is a connection and the computer obtains an IP from the Router, but the Browser does not work.

Try this, http://www.ezlan.net/clean.html#refreshnet

if they were the same chip set the bad drivers from the broadcom based 1450 could stop the new adapter from working properly. ive had a problem like this with my 2 atheros based cards.

i had a similar issue, i even replaced the mini-pci card (broadcom) in the laptop and no dice. There was a setting in the properties that says "Automatically connect to non preferred networks" I checked this and voila it works. Give it a go, might save you some $$
