Inspiron 15 3000-3573 with Ubuntu 18.04.2: no wifi on resume
Would be great to hear if anyone has already met and dealt with such issues, or has a general insight to this? Basically I can't get a wifi connection on 'resume' and am forced to reboot. I can see from dmesg a firmware crash message from the ath10k driver so that can't be right.
The device is a 'QCA9377 hw1.1' and I seem to have the latest available firmware (although the directory location suggests it might not be optimum for hw1.1 - /lib/firmware/ath10k/QCA9377/hw1.0/ ?):
The machine originally came with 16.04 pre-installed and a 1TB non-SSD. Wifi was 'tricksy' on resume but tolerable. In search of shininess I updated to 18.04. Everything still fine. Next step was to replace with an SSD and that's when this issue came up. I had little personal data at that stage so did not transfer over anything to the SSD. I'm wondering were there Dell-specific drivers on the original disk?
