Ok, after a few hours the problem came back so bios upgrade is not a solution. While searching for a possible solution I discovered that there are a number of distributions inpacted by this bug (not all debian based) so it must be a kernel bug. https://forums.linuxmint.com/viewtopic.php?t=290987 https://forums.kali.org/showthread.php?45021-rtl8822be-wifi-not-working-after-updated-to-kernel-5-2-0 https://access.redhat.com/discussions/4302461 For now I'm reverting to eoan because the wifi is not usable in focal.
I'm attaching my kernel log from the last crash. ** Attachment added: "kernel log from last crash" https://bugs.launchpad.net/ubuntu-mate/+bug/1875099/+attachment/5369234/+files/kern.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1875099 Title: RTL8822BE Wifi [10ec:b822] subsystem [17aa:b023] crashes on 20.04 on Lenovo Legion Y530 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-mate/+bug/1875099/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
