Title:
Qualcomm QCA6174 [168c:003e] (rev 32) on Ubuntu Bionic fresh install
has flakey wifi and no BT Bluetooth
Status in linux package in Ubuntu:
Confirmed
Bug description:
On fresh install on Yoga920 of Bionic Beaver 18, wifi and bluetooth
work. Then they degrade with BT not working withing a day or five,
and wifi is consistently inconsistent. On the bluetooth gui, user is
unable to turn bt on or off and the CLI shows no blocking on bt but it
doesn't work.
I think this has to do with the Qualcomm QCA6174 [168c:003e] (rev 32)
on Ubuntu Bionic and the ath10k_pci driver but Qualcomm nor Lenovo
have answers.
