I had this problem once. I disabled windows wifi management, let the Intel software manage the wifi connection. See if that helps, also make sure you have the the newest firmware installed on the router.

Any advice on how to go about this?  I'm unclear how to differentiate between Windows management of my Wifi connecion and the Intel software..

Thanks,

Ah ha!  Thank you Area_51, this really seems to have done the trick.  Here is what I did:

1. Right-click My Computer, and then click Manage
2. In Computer Management, double-click Services and Applications in the
console tree, and then click Services
3. In the details pane, right-click Wireless Zero Configuration, then
click Properties
4. In the Startup type box, click Disabled , and then click OK
5. Quit Computer Management, and then restart the computer
6. After restart, to go Control Panel to access the Intel ProSet configuration area, and configure your wireless connection there

Cheers,

Yeah that works too. I went start|control panel|network connections| right click over the wireless network, select properties, select wireless networks tab, uncheck box next to "Use windows to configure my wireless network".

Hmm, well there goes that theory. Do you have any other devices operating on the 2.4ghz band? Like a cordless phone?

Actually, it's version 4!

I'm going to take a stab in the dark here; is your router version 1? They have a version 1, 2, & 3.

Nope.  Nothing that would cause an interference problem that I can think of.

There was one other guy on this forum who had the same problem. He ended up removing and reinstalling the Intel Proset software. That cleared up his connection issues, wouldn't hurt to give it a try. I've run out of other idea's.
