Trouble connecting to a specific WiFi ssid (association timeout)

[cen]

Hi

Up-to-date Fedora 30

Thinkpad x260, Intel wifi, wpa_supplicant v2.8

I got a brand new tp-link archer c6 and set up 2.4Ghz mixed ssid and 
5Ghz ac/mixed ssid. I can connect to 5GHz just fine but 2.4GHz gives 
association timeout (see dmesg below). It just keeps asking for password 
every 20 seconds to infinity. This is the only 2.4 b/g/n ssid that I 
have trouble connecting with, ever. My android phone and 2 windows 
laptops can connect to this ssid just fine so there must be a very 
specific problem with my laptop/Fedora combo.

I have yet to try with an unsecured ssid, that is next on the debug 
list, currently it is set to WPA2 personal/AES.

Anything else I can try to solve this mystery?

Are you using NetworkManager?

I have had issues with the Intel wifi on my laptop giving me a similar 
problem.  The way to fix it has usually been to unload the module and 
reload it.

Are you saying that there are multiple SSIDs on both frequencies?  I 
have found that using the same SSID(s) on both works well.  Devices that 
can do 5GHz will use that and no one has to think about which one to use.

Yes, I use NetworkManager.

I haven't tried reloding the module yet, I tried rebooting multiple 
times but that didn't help.

I use  different names for each SSID to have a clear idea what I am 
connecting to. I don't even really need 2.4Ghz because 5Ghz works 
perfectly I just want to get to the bottom of this.

I'll try Fedora 31 and change around the 2.4Ghz security settings to see 
if anything helps.


Best regards, cen

If you're rebooting, then reloading won't make any difference.

Ok.  I don't have any other suggestions.  I did see a thread on the 
linux wireless mailing list about someone that couldn't connect at a 
couple of specific Starbucks locations with similar symptoms, but I 
don't think there was any solution found.
