I just install Ubuntu 18.04 yesterday, and it seems like Ubuntu cannot detect wifi adapter. The card is working on Windows, so it should not be a problem. I also have the same firmware as the one stated on Intel website (iwlwifi-9260-th-a0-jf-a0-34.ucode). Checking the log, I see iwlwifi failed with error -110.
Any idea how to troubleshoot this issue?
Thanks,
Below is the details log:
