Title:
Wifi adapter not found after suspend (iwlwifi)
Status in linux package in Ubuntu:
Expired
Bug description:
Hello,
I am finding that the network adapter " Network controller: Intel Corporation
Wireless 7260 (rev bb)
" (iwlwifi) is reported as disabled, or not present after a lengthy suspend.
This is an identical issue to those reported for Realtek, but I have not found
an existing report for Intel.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1779817
This was no a problem in 16.04 or 17.10 with the identical hardware.
18.04 was installed clean.
Happy to provide more information, however, I am not exactly sure what
information to provide?
Thanks in advance,
