Bug Description

I see frequent disconnects due to reason=4, which would be o.k. if reconnects worked fine. However often on reconnects 4-way handshake times out and I'm prompted to re-enter our wifi pass-phrase, sometimes as frequent as every few minutes - a major annoyance :-(

Problem seems to depend a bit on network traffic. However only my notebook with ubuntu 17.04. seems to be affected. Two iphones, an android phone and a chromebook seem to have no wifi problems at all.

Also, when I set up wls2 manually in /etc/network/interfaces I haven't seen failed reconnects so far.

I have had this problem since 16.04. Various work arounds suggested on the web like changing wifi channel, disabling IPv6, or disabling DHCP haven't affected this problem.
