So, the driver was previously unsigned, then signed and included in the original Ubuntu kernel for 18.10, then subsequently unsigned during an update somewhere along the way?
That doesn't make sense to me - would have to try and find upstream to work out what has happened. Larry Finger suggests that Realtek has rewritten the driver and his GitHub repo is only for older kernels that do not already ship the r8822be driver. 4.21 is quoted as when this new driver will drop. https://github.com/lwfinger/rtlwifi_new/issues/408#issuecomment-426299298 ** Bug watch added: github.com/lwfinger/rtlwifi_new/issues #408 https://github.com/lwfinger/rtlwifi_new/issues/408 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1806472 Title: RTL8822BE WiFi Disabled in Kernel 4.18.0-12 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1806472/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
