How to get Intel 9260 (RE-WFKIT-9260NVP) WiFi/BT working on Ubuntu 20.04?
I installed Ubuntu 20.04 on my Up Squared, according to the instructions here: https://github.com/up-board/up-community/wiki/Ubuntu_20.04
While in the installer I selected the option to allow 3rd party wireless firmware (and the installer could see nearby wifi networks.)
After I finished updating the kernel and I rebooted, I proceeded to the next instructions and accidentally ran
sudo apt install firmware-ampak, even though I realized later I didn't need to. I have subsequently removed that package.
However, when I run the commands listed below it to test wifi and bluetooth, both of them do not indicate they are working:
user@user-UP-APL01:~$ sudo iwlist wlan0 scan wlan0 Interface doesn't support scanning.
hcitool scan Scanning ... ^C
(there is never anything found, even though I know I have discoverable bluetooth TV in range, which I can see from a different linux machine.)
It seems like the firmware for the wifi was found...
dmesg | grep iwlwifi [ 4.967123] iwlwifi 0000:04:00.0: enabling device (0000 -> 0002) [ 4.996111] iwlwifi 0000:04:00.0: loaded firmware version 46.4d093a30.0 op_mode iwlmvm [ 5.049884] iwlwifi 0000:04:00.0: Detected Intel(R) Wireless-AC 9260 160MHz, REV=0x324 [ 5.102601] iwlwifi 0000:04:00.0: base HW address: 00:91:9e:f4:3f:10 [ 5.508127] iwlwifi 0000:04:00.0 wlp4s0: renamed from wlan0
But in the GUI it just shows the wifi as disabled (and like I say, no BT devices are found.)
Another forum post said I needed to edit BIOS settings like is mentioned here: https://github.com/up-board/up-community/wiki/Wireless. But when I went to check them, my
PCI Express Root Port 6 was set correctly (presumably there's been a BIOS update since that was written, so that that's not needed anymore on newer systems?)
I'm at a loss. How can I debug the issue from here and get my wifi/BT working?
