Sometimes Intel AX201 fails to associate with AP: [ 839.290042] wlp0s20f3: authenticate with xx:xx:xx:xx:xx:xx [ 839.291737] wlp0s20f3: send auth to xx:xx:xx:xx:xx:xx (try 1/3) [ 839.350010] wlp0s20f3: send auth to xx:xx:xx:xx:xx:xx (try 2/3) [ 839.360826] wlp0s20f3: authenticated [ 839.363205] wlp0s20f3: associate with xx:xx:xx:xx:xx:xx (try 1/3) [ 839.370342] wlp0s20f3: RX AssocResp from xx:xx:xx:xx:xx:xx (capab=0x431 status=0 aid=12) [ 839.378925] wlp0s20f3: associated [ 839.431788] wlp0s20f3: deauthenticated from xx:xx:xx:xx:xx:xx (Reason: 2=PREV_AUTH_NOT_VALID) It fails because EAPOL hasn't finished. Increase the session protection duration to 1200TU can eliminate the problem.
