I installed Debian GNU/Linux testing on a Toshiba Satellite U500-183
that seems to have this wireless device. I have this kernel installed::
ii linux-image-2.6.32-trunk-amd64 2.6.32-5 Linux
2.6.32 for 64-bit PCs
and downloaded rtl8192se_linux_2.6.0014.0115.2010.tar.gz from Realtek's
web site, compiled it (make CC=gcc-4.3, no errors) and installed it as
per #20. It worked the first time and I connected successfully to my
access point. However after a couple of minutes it loses connection. I
can only re-establish connection after rebooting and then it looses
connectivity again after a couple of minutes.
