[Kernel-packages] [Bug 1906600] Re: WiFi disconnects continually (goes "down" in NetworkManager)
I have been running the mainline kernel since Saturday and have not seen any of the network disconnect notifications or password prompts since. I had been seeing several of them a day since the kernel update described in my original comment, so it appears the problem has been fixed for me. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1906600 Title: WiFi disconnects continually (goes "down" in NetworkManager) Status in Ubuntu MATE: Confirmed Status in linux package in Ubuntu: Incomplete Status in network-manager package in Ubuntu: Confirmed Bug description: Hello everybody and thank you in advance for your help. After a recent update, my machine rebooted and appeared to be fine, but after a short time the WiFi dropped and the NetworkManager applet shows that the interface is down. I am also getting prompted for a password (which was previously saved) and when I click on connect it will establish the connection for a short time, but then goes down again.

I'm having a similar errors, I think it has something to do with the latest kernel updates. In my case, the kernel modules were updated on Dec 1. From the apt history.log: Start-Date: 2020-12-01 07:41:57 Commandline: aptdaemon role='role-commit-packages' sender=':1.297' Install: linux-image-5.4.0-56-generic:amd64 (5.4.0-56.62, automatic), linux-headers-5.4.0-56-generic:amd64 (5.4.0-56.62, automatic), linux-headers-5.4.0-56:amd64 (5.4.0-56.62, automatic), linux-modules-extra-5.4.0-56-generic:amd64 (5.4.0-56.62, automatic), linux-modules-5.4.0-56-generic:amd64 (5.4.0-56.62, automatic) Upgrade: linux-headers-generic:amd64 (5.4.0.54.57, 5.4.0.56.59), linux-libc-dev:amd64 (5.4.0-54.60, 5.4.0-56.62), linux-image-generic:amd64 (5.4.0.54.57, 5.4.0.56.59), snapd:amd64 (2.47.1+20.04, 2.48+20.04), linux-generic:amd64 (5.4.0.54.57, 5.4.0.56.59) End-Date: 2020-12-01 07:43:16 I didn't restart my computer at the time, but shut it down overnight and restarted in the morning of December 2, and that's when I started having very similar issues as described in the original submission. The biggest difference is that the time period of WiFi network disconnects is longer - normally it'll work for a half hour or more, but eventually I'll get disconnected and prompted for a password on a network that I've been connecting to for years.
