Description of problem: In about the last 6 months I had noticed this adapter being choosy about which networks it would connect to easily, I thought is it may have been the card but lived with it until recently. This card will no longer connect to any network I select at all with the error below and times out. I updated recently from FedoraCore 29 to 30 and have tried a 2nd card which is brand new and I get the same results. I am currently using a USB dongle ( 2.4 ) to get by. This looks to be a driver / firmware issue I am sure if I use an older install and or windows it would seem that these cards would work flawlessly ( I will test this ). The error from WPA Supplicant is: wpa_supplicant[1237]: wlp3s0: CTRL-EVENT-SCAN-FAILED ret=-22 retry=1 Version-Release number of selected component (if applicable): Latest ( not sure what the release number is ) How reproducible: Very easy as its instantaneous on every connection attempt Steps to Reproduce: 1. Just try and connect to any wireless network 2.4G or 5G 2. 3. Actual results: wlp3s0: CTRL-EVENT-SCAN-FAILED ret=-22 retry=1 Expected results: Connect to any 2.4G or 5G Access Points. Additional info: The card in question is: Intel Corporation Centrino Ultimate-N 6300 Firmware, iwlwifi 0000:03:00.0: loaded firmware version 9.221.4.1 build 25532 op_mode iwldvm Output from dmesg: [ 115.603574] wlp3s0: send auth to 5c:b0:66:14:25:9a (try 1/3) [ 115.913870] wlp3s0: authenticated [ 115.914506] wlp3s0: associate with 5c:b0:66:14:25:9a (try 1/3) [ 115.915807] wlp3s0: RX AssocResp from 5c:b0:66:14:25:9a (capab=0x411 status=0 aid=1) [ 115.918315] wlp3s0: associated [ 115.918907] wlp3s0: deauthenticating from 5c:b0:66:14:25:9a by local choice (Reason: 3=DEAUTH_LEAVING)
I tested with a live distro running kernel 4.15 ( Linux Mint ) and the card works on both 2.4 and 5 Ghz.
*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There are a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 30 kernel bugs. Fedora 30 has now been rebased to 5.2.9-200.fc30. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 31, and are still experiencing this issue, please change the version to Fedora 31. If you experience different issues, please open a new bug report for those.

From a response I got from Luca at Intel on this here is his feedback, This error is -EINVAL, which means that the driver is not recognizing a parameter passed to it. It's hard to tell exactly what is causing that without further investigation. Are you able to compile the kernel and do some tests? One way you could do it is to replace the -EINVAL with a line number, so we can try to see where the invalid parameter error is coming from. Doing something like this: http://pastebin.coelho.fi/03fa29d951db5405.txt Then the returned error should correspond to a line number on the driver. Hope this helps to resolve this one..
(In reply to Nigel Sollars from comment #5) > Actual results: > wlp3s0: CTRL-EVENT-SCAN-FAILED ret=-22 retry=1 this reminds me of a similar bugzilla I've seen some weeks ago (bz1703745). > From a response I got from Luca at Intel on this here is his feedback, > > This error is -EINVAL, which means that the driver is not recognizing a > parameter passed to it.

After getting more advice and trying a couple of things, this work around works for me, NetworkManager/conf.d/iwl.conf With contents, [device] match-device=driver:iwlwifi wifi.scan-rand-mac-address=no

Not 100% sure why the problem went in in the transition from f29 to f20, but I suspect the issue has something to do with latest enablement of CONFIG_MESH _ at least it proved to be a problem at least with broadcom 'wl' driver as per https://bugzilla.redhat.com/show_bug.cgi?id=1695696#c12 https://bugzilla.redhat.com/show_bug.cgi?id=1703745#c64 In case you want to try, I keep a version of wpa_supplicant where CONFIG_MESH is commented in the build config: https://copr.fedorainfracloud.org/coprs/dcaratti/wpa_supplicant/ and then report the testing results that to the iwlwifi maintainer.
I can confirm that the workaround that #9 proposes works: I have a T430s that I just swapped an Intel Centrino Ultimate-N 6300 card in on, the last that the t430s supports. previous card was an Intel Centrino Wireless-N 2200, worked fine. After the swap I was getting lists but I could not connect to networks. After applying the workaround and restarting NetworkManager, I can connect to both 2.4Ghz and 5Ghz networks.
