I am also experiencing multiple WiFi issues with Librem 15v4. I would like to add that this is a brand new device. I’m dual booting PureOS and Ubuntu 18.04. The WiFi issues really only started when I started using Ubuntu. I would attempt to connect to my home WiFi, and it would state “Connecting” for about a minute, then state that the connection failed. No amount of turning WiFi off/on or killswitch off/on would work. Eventually I tried turning hwcrypt off and disabling IPv6, which seemed to do the trick for about 3 hours or so. But then speeds got really slow, pinging to google.com gave 55% packet loss. Then it stopped working completely, back to “Connecting” and failing again. I then tried restarting the NetworkManager service by doing
sudo service network-manager restart then followed up with
sudo ifdown wlp1s0; sudo ifup wlp1s0 just to be sure. This, surprisingly, worked… For a day. I then switched to PureOS to check some things out, noticed I was having wifi issues there now. Switched back to Ubuntu, back to square friggin’ one. Unable to connect again. I’m typically able to connect to my phone’s wifi hotspot however. But this time I wasn’t. I restarted multiple times. After the 4th or 5th restart, it started working again (?).
But even though it’s connecting now, the connection is really spotty. Attempting to play League of Legends is impossible as the network connection will drop out of nowhere for 3-5 minutes, or I’ll experience severe packet loss.
It seemingly has a mind of its own.
