Restarting 0x2000000 Status in linux package in Ubuntu: Invalid Bug description: My wifi won't work after I wake my laptop up from standby. This problem looks quite the same as #1099487 or #944271. But I experienced this bug on Xenial with 4.4.0-22-generic (amd64). A `sudo modprobe -r iwlwifi && sudo modprobe iwlwifi` doesn't solve the problem. (A reboot does.)
