@kaihengfeng yes both BT and Wifi stop working intermittently. I found a fix that will bring both the BT and Wifi back if they go down, however. By removing the BT-related modules from the kernel, issuing a USB reset, and then loading the BT modules back into the kernel. BT will work after that.
For the Wifi, I reset the PCI device via Linux and rescan the PCI bus, and then I set the wireless mode to "managed" and it works again. I set systemd to remove the Wifi module from the kernel before suspending, and then have systemd re-insert the Wifi module into the kernel upon waking up from sleep. I can include the scripts I use to do this, if anyone is interested. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861295 Title: Bluetooth not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1861295/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
