I've recently built a PC and I installed a Gigabyte GC-WB1733D-1, Intel chipset 9260. It was intermittently disconnecting from the Mesh Wifi we have for both PopOS and Windows, but it seemed to work fine after setting a preference for the 5GHz band. This worked fine for about 2 weeks.
Now it shows no networks, and the only thing that has changed is that I ran some Pop OS updates last night.
- Windows works fine
- Bluetooth module on the card works fine for both Windows and Pop
- My personal hotspot on my phone works, albeit very weak
I reckon the card wasn't working 100% before, because it shouldn't really complain about bands.
