Glad to find this forum
I just installed Windows 7 RC x64. Everythign works fine even for my wireless card: linksys wpm300n at least for browsing websites etc. However, I found some problems today when I was watching live games at ESPN360.com. After I watched the games for a while, say about 5 mins, I would lose my internet connection, and had to restart the computer in order to recover it. I tried three times, the same problems recurred. Eventually, I have to run a ethernet cable to my router and disable the wireless card.
I have the latest version of the driver from linksys website. Does anyone else have similar problems?
