After reading the bug you linked (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881214), it does look very similar indeed, the result is the same, and it seems to happen "randomly" after long usage, so maybe linked to a router switch indeed.
I am not expert enough to try many things on my own unfortunately, but I can try to investigate more if you give me directions. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881675 Title: Intel Wireless 8260 [8086:24f3] Subsystem [8086:0010] iwlwifi Microcode SW Error ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881675/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
