Sometimes I am not able to connect to wi-fi network.
dmesg contains lots of crda messages: [ 437.468001] wlp4s0: authenticate with fc:f5:28:3c:f4:2e [ 437.476830] wlp4s0: send auth to fc:f5:28:3c:f4:2e (try 1/3) [ 437.483129] wlp4s0: authenticated [ 437.486803] wlp4s0: associate with fc:f5:28:3c:f4:2e (try 1/3) [ 437.490883] wlp4s0: RX AssocResp from fc:f5:28:3c:f4:2e (capab=0x411 status=0 aid=3) [ 437.491144] wlp4s0: associated [ 437.491287] cfg80211: Calling CRDA for country: TW [ 437.494542] ath: EEPROM regdomain: 0x809e [ 437.494548] ath: EEPROM indicates we should expect a country code [ 437.494552] ath: doing EEPROM country->regdmn map search [ 437.494555] ath: country maps to regdmn code: 0x50 [ 437.494558] ath: Country alpha2 being used: TW [ 437.494561] ath: Regpair used: 0x50 [ 437.494564] ath: regdomain 0x809e dynamically updated by country IE [ 437.494593] cfg80211: Regulatory domain changed to country: TW [ 437.494597] cfg80211: DFS Master region: JP [ 437.494600] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp), (dfs_cac_time) [ 437.494606] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (N/A, 3000 mBm), (N/A) [ 437.494611] cfg80211: (5270000 KHz - 5330000 KHz @ 40000 KHz), (N/A, 1700 mBm), (0 s) [ 437.494615] cfg80211: (5490000 KHz - 5590000 KHz @ 80000 KHz), (N/A, 3000 mBm), (0 s) [ 437.494618] cfg80211: (5650000 KHz - 5710000 KHz @ 40000 KHz), (N/A, 3000 mBm), (0 s) [ 437.494622] cfg80211: (5735000 KHz - 5835000 KHz @ 80000 KHz), (N/A, 3000 mBm), (N/A) [ 440.070782] cfg80211: Calling CRDA to update world regulatory domain [ 440.074002] cfg80211: World regulatory domain updated: [ 440.074010] cfg80211: DFS Master region: unset [ 440.074013] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp), (dfs_cac_time) [ 440.074020] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (N/A, 2000 mBm), (N/A) [ 440.074024] cfg80211: (2457000 KHz - 2482000 KHz @ 40000 KHz), (N/A, 2000 mBm), (N/A) [ 440.074028] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (N/A, 2000 mBm), (N/A) [ 440.074031] cfg80211: (5170000 KHz - 5250000 KHz @ 80000 KHz), (N/A, 2000 mBm), (N/A) [ 440.074035] cfg80211: (5735000 KHz - 5835000 KHz @ 80000 KHz), (N/A, 2000 mBm), (N/A) [ 440.074039] cfg80211: (57240000 KHz - 63720000 KHz @ 2160000 KHz), (N/A, 0 mBm), (N/A) [ 440.074368] cfg80211: Calling CRDA for country: RU [ 440.077898] cfg80211: Regulatory domain changed to country: RU [ 440.077907] cfg80211: DFS Master region: ETSI [ 440.077910] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp), (dfs_cac_time) [ 440.077916] cfg80211: (2402000 KHz - 2482000 KHz @ 40000 KHz), (N/A, 2000 mBm), (N/A) [ 440.077921] cfg80211: (5170000 KHz - 5250000 KHz @ 80000 KHz), (N/A, 2000 mBm), (N/A) [ 440.077925] cfg80211: (5250000 KHz - 5330000 KHz @ 80000 KHz), (N/A, 2000 mBm), (0 s) [ 440.077928] cfg80211: (5650000 KHz - 5730000 KHz @ 80000 KHz), (N/A, 3000 mBm), (0 s) [ 440.077932] cfg80211: (5735000 KHz - 5835000 KHz @ 80000 KHz), (N/A, 3000 mBm), (N/A) repeated multiple times.
