Intel 3945ABG Wireless Card Not Working?

I have an Inspiron E1405 with an Intel 3945ABG Wireless Adapter, Windows Vista 32bit (Not sure what other info about my system I would need to offer here). 

The wireless internet worked fine for a long time (years) then one day just started going in and out randomly.  I tried uninstalling and installing all Networking Drivers, which didn't make any changes.  I then read somewhere to do a Netsh Winsock Reset, I did that and it worked awesome for about a month.  It started going in and out again last week.  I tried rolling back to the previous version of my wireless driver, but it worked a little better at first and then went right back to the same behavior.  A friend of mine is more tech savvy, had me download and run CCleaner, and uninstall and reinstall my drivers for the wireless adapter and Service Pack.  I used to be able to get the wireless to connect if I rebooted my system and it would work momentarily.  Now it doesn't work at all and if it connects it's only for a few seconds.  I can't even find my home network right now and I'm about 15 ft. from the Router (Which I just replaced, thinking it was the issue, got a brand new Linksys 160N). 

I'm about to throw this laptop out the window because I'm sick of sitting here for two days trying to fix this stupid thing so I can get back to work.  Any help is much appreciated!!!
