Vista - Full Strength Local and Internet-put internet permenantely drops

(Self Built, P5NE SLI Asus motherboard, Nvidia 7600 Video Card, 2 Gigs Ram,
2.2 Ghz Core 2 duo, Vista 32bit home premium, Dlink Airplus G DWL g510)

I was wondering if anyone out there had some similar problems like myself.
I'm having random connection issues with Vista and wireless. It is the
strangest thing because when the problems start, it's only the browsers and
email clients that cannot connect. For some odd reason, a p2p client such as
Azureus will continue to download.
I thought it might be a firewall issue so I disabled it and it wasn't the
case.

The thing about this intermittent problem is that it takes a restart to
correct the problem. The repair connection doesn't work at all. Throughout
all this I have full strength signals from my router and it says I am
connected to both local and internet. This requires me to reboot about once a
day, sometimes twice. The problem still persists when I changed out my Dlink
wireless card with an edimax one. I also changed wireless routers from a
Netgear to Buffalo. Problem still exists.The problem exists with both IE7 and
Firefox. I updated my Asus p5ne sli motherboards firmware, hoping that would
help but to no avail.

Its disheartening that I will have to deal with this computer until I get a
new one as this is a recent build with decent specs (Vista Premium, 2.2 Core
2 Duo, 2 gigs ram, Nvidia 7600 and with expensive quiet fans and heatsinks, I
built for quietness).

I suspect that the motherboard might be the issue. If anyone has any clues,
please help me out. Thanks.

P.S. I've flashed my buffalo router with the tomato linux firmware and
disabled ipv6 to see if that would help but the problem is still there.

of the details but I did at the time have to get new atheros drivers for
the wireless card. I think I had to go to their czech website
www.atheros.cz to get the latest drivers for the chipset in the wireless
card, but that might not be needed any longer.
