Win7 RC x64: issues with linksys wmp300n

Glad to find this forum.

I just installed win7 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?

Thank you!

I'm having the exact same issue with the same wireless card.

It must be a problem with Win7 RC because I have even tried reconfiguring my router to no avail. I'm out of ideas as to what it could be and am hoping for an update from MS soon.
