Is that a known problem? I'm currently running the Debian 2.6.39-rc7-amd64 kernel from unstable; I believe rc7 may be the first Debian kernel to work with this adapter. I also needed to patch Debian's firmware-realtek package to include the relevant firmware as detailed here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=625614. With respect to the connection quality I see: Channel:1 Frequency:2.412 GHz (Channel 1) Quality=65/70 Signal level=-45 dBm And during transfers "iw event -t" shows nothing other than the occasional scan started/finished pair.
