Can you give me the pcie ID for the wireless controller (lspci -n)
Of course! The wireless controller is the 3b:00.0 right? lspci -n 00:00.0 0600: 8086:3e20 (rev 0d) 00:01.0 0604: 8086:1901 (rev 0d) 00:02.0 0300: 8086:3e9b (rev 02) 00:04.0 1180: 8086:1903 (rev 0d) 00:08.0 0880: 8086:1911 00:12.0 1180: 8086:a379 (rev 10) 00:14.0 0c03: 8086:a36d (rev 10) 00:14.2 0500: 8086:a36f (rev 10) 00:15.0 0c80: 8086:a368 (rev 10) 00:15.1 0c80: 8086:a369 (rev 10) 00:16.0 0780: 8086:a360 (rev 10) 00:16.3 0700: 8086:a363 (rev 10) 00:17.0 0106: 8086:a353 (rev 10) 00:1b.0 0604: 8086:a340 (rev f0) 00:1c.0 0604: 8086:a338 (rev f0) 00:1c.4 0604: 8086:a33c (rev f0) 00:1d.0 0604: 8086:a330 (rev f0) 00:1f.0 0601: 8086:a30e (rev 10) 00:1f.3 0403: 8086:a348 (rev 10) 00:1f.4 0c05: 8086:a323 (rev 10) 00:1f.5 0c80: 8086:a324 (rev 10) 01:00.0 0302: 10de:1fb8 (rev a1) 02:00.0 0604: 8086:15da (rev 02) 03:00.0 0604: 8086:15da (rev 02) 03:01.0 0604: 8086:15da (rev 02) 03:02.0 0604: 8086:15da (rev 02) 04:00.0 0880: 8086:15d9 (rev 02) 3a:00.0 0c03: 8086:15db (rev 02) 3b:00.0 0280: 8086:2526 (rev 29) 3c:00.0 ff00: 10ec:525a (rev 01) 3d:00.0 0108: 8086:f1a6 (rev 03)
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.
Great, thanks a lot!
OK, the latest kernel (5.6.0) indeed fix the problem! Thanks a lot for your help :)
