Comment 133 for bug 291760


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
