I have 5 systems running Lubuntu and only one is having this issue which is also using an Intel wireless card. The other 4 systems are using either a Buffalo or TPLink card. I have tried checking the regulatory domain, disabled ipv6, tried enabling antenna aggregation, tried 2.4ghz instead of 5, disabled n mode, disabled bluetooth, disabled bluetooth coexistence, disabled power management, turned off watchdog, and I am sure I have tried a few other things that I do not recall at the moment. <div class="HOEnZb"><div class="h5"> On 6/7/17 2:48 PM, Jonathan Thacker wrote: > I upgraded lubuntu to the newest version a month ago and ever since then, the wifi will disconnect randomly and will not reconnect without a reboot. I went to the forums and could not find a specific answer. I ran the script suggested on the networking section of the forums and posted the output below (2 outputs, one with wifi working, one after it disconnects). > > > > With Working WIFI > > > ##########
