Public bug reported:
I can connect with WPA to the AP, I can also disconnect and then
reconnect
but if the AP is switched off while I am connected, then I have to
restart in order to get wifi working again
I would be happy to try rmmod or restarting services, but I need
instructions for it, as until now I did everything at the same time, and
finally nothing worked
I have a Thinkpad T61 (766418G) with Intel(R) Wireless WiFi Link 4965AGN
