Desktop Wireless Connection Being Dropped

[A6Quattro]

Hi All-

I inherited a business client, with a desktop that they use to connect to wireless. They had connectivity problems, so I installed a new PCI wireless card. No change. I swapped it out then for the wireless card in my personal computer. Still no change.

Their network strength was two or three bars with the first to cards. The third card wwasa an older Netgear with three antenna wires going to a separate base, and it held a constant three bars.

The lady using the computer is getting bumped off the wireless. She says that it's mostly in the afternoon.

Regardless of whether she is connected or not, the Windows tray icon shows her as being disconnected.

She is running Windows 7 Professional x64.

Any ideas on where to start???

Thanks for the Help!

I think this one is fixed. We still have the icon as showing disconnected, but we boosted the strength. By using a WiFi Channel Scanner program, we found that someone had set up a new router that was using our channel. We changed channels and raised the router up higher, and it seems to work much better now!
