[Vladimir Mencl <291760@xxxxxxxxxxxxxxxxxx>]

Hi,

I'm having the same problem on a ThinkPad T410si with an RTL8191SE.

What in the end helped me to get around this problem was to set the
driver options to disable both software level and firmware level
powersaving - the problem has virtually gone away.

Try creating /etc/modprobe.d/rtl8192se-options.conf with:

options rtl8192se ips=0 swlps=0 fwlps=0

Cheers,
Vlad
