Windows 7: What network card do you use?

I've been having this problem ever since Windows Vista 64bit, a problem I've been trying to find a solution to for the last 3 weeks. It's REALLY frustrating to realize that the problem was the network card. I was using a RT2561 branded as a Sabrent wireless card. This card would work fine in normal use, downloading, but when it came to uploading or anything JAVA, it would crash and hardlock the computer. So I thought it might be the OS, then I installed Windows 7 and I still have this problem, even after switching hdds/memory. The problem lies within the network card because once it's removed, theres no crashing.

So I want to ask, what wireless network cards do you guys use that work with Windows 7 64bit. I know there are a few RT61 chipsets out there (Linksys WMP54G) but the RT61 doesn't work well with my machine as it has more than 4GB of memory (article: Ralink RT61 or (RT256x/RT266x) causes freezing Windows 7 x64)

Sad but funny, I went to the store to buy a bunch of network cards to try, and low and behold, most of them use the RT61 chipset . Unfortunately, my location doesn't permit any wired connection. What network cards have you guys found compatible? Do you have 4GB Ram+?

Thanks

I only used x86 so far, but my D-Link Wireless G DWA-110 USB Adapter seems to work fine with windows 7, have no problems what so ever.

Have you tried older versions of the driver? Someone said try 2.0.3.0 of the RALink drivers.
