Comment 1 Peter Robinson 2020-03-26 11:21:11 UTC

Can you give me the pcie ID for the wireless controller (lspci -n)

Comment 2 Dobmec 2020-03-26 12:56:32 UTC

Of course! The wireless controller is the 3b:00.0 right?

Comment 3 Peter Robinson 2020-03-26 12:59:56 UTC

So I think this is a kernel problem (the iwlwifi team's QA has been dreadful of late) and it should be fixed in the next Fedora build as a fix went upstream in the last day or so:

commit cf52c8a776d1b31493a987a0fb3c4dbaa0f7f2cc
Author: Luca Coelho <luciano.coelho>
Date:   Tue Mar 17 12:33:41 2020 +0200

    iwlwifi: pcie: add 0x2526/0x401* devices back to cfg detection
    
    Three devices, with PCI device ID 0x2526 and subdevice IDs 0x4010,
    0x4018 and 0x401C were removed accidentally.  Add them back.

Comment 4 Dobmec 2020-03-26 13:05:54 UTC

Great, thanks a lot!

Comment 5 Dobmec 2020-03-31 06:59:52 UTC

OK, the latest kernel (5.6.0) indeed fix the problem! Thanks a lot for your help :)
