Not detecting WiFi adapter

nedo99

Hi,

We ordered this kit https://up-board.org/up-squared-robomaker-pro-kit/ which comes with WiFi adapter including 2 antennas. I connected it, but Ubuntu does not see it.

lspci -nn | grep -i network does not show the WiFi controller, only ethernet ones. I tried downloading the latest firmware files but no help. Looking at dmesg | grep iwl does not show anything. It seems like it is not connected at all. I am using pre-installed Ubuntu with kernel 4.15.

Not sure if antennas are connected properly, but I guess it should still recognize it. What is the best way to check if everything is connected as it should be? Any inputs on what to try next?

Regards,
Nedim

I'm facing the same problem. Please help me if you are able to solve the problem.

have you tried to unplug and re-plug the WiFi module?

Can you please confirm the WiFi module type (maybe taking a picture of the module)?

Can you also share your complete dmesg log file?

Also what BIOS version is installed in your system, is it 5.0?

Hi @DCleri , thanks for the support.
I had the outdated BIOS 4.2. Once I upgraded the BIOS to latest version, then the wifi module got detected.
