But it is in contrast with what I found in the syslog: Nov 21 07:53:23 MrProper kernel: [ 9.591563] ath: Regpair used: 0x3a Nov 21 07:53:23 MrProper kernel: [ 9.591573] cfg80211: Updating information on frequency 5180 MHz with regulatory rule: Nov 21 07:53:23 MrProper kernel: [ 9.591581] cfg80211: (5140000 KHz - 5360000 KHz @ 80000 KHz), (N/A, 3000 mBm) [...] - 5360000 KHz @ 80000 KHz), (N/A, 3000 mBm) Nov 21 07:53:23 MrProper kernel: [ 9.591654] cfg80211: Updating information on frequency 5300 MHz with regulatory rule: Nov 21 07:53:23 MrProper kernel: [ 9.591661] cfg80211: (5140000 KHz - 5360000 KHz @ 80000 KHz), (N/A, 3000 mBm) Nov 21 07:53:23 MrProper kernel: [ 9.591668] cfg80211: Updating information on frequency 5320 MHz with regulatory rule: Nov 21 07:53:23 MrProper kernel: [ 9.591675] cfg80211: (5140000 KHz - 5360000 KHz @ 80000 KHz), (N/A, 3000 mBm where there are @80MHz frequency slots. Is it possible that the system, showing all these different reg. domains from different cards, chose the most constrained one? 2016-11-21 11:53 GMT+01:00 Michal Kazior : > On 21 November 2016 at 10:46, Matteo Grandi wrote: >> Dear Bob, Michal, all, >> >> I've just tried your advices (actually I already tried it following >> the wireless.wiki.kernel web pages) and I had a look at the syslog >> while I was typing the commands >> At the beginning I have this > [...] >> Other (hopefully) useful info: >> root@MrProper:~# iw reg get >> global >> country US: DFS-UNSET >> (2402 - 2472 @ 40), (3, 27), (N/A) >> (5170 - 5250 @ 40), (3, 17), (N/A) >> (5250 - 5330 @ 40), (3, 20), (0 ms), DFS >> (5490 - 5600 @ 40), (3, 20), (0 ms), DFS >> (5650 - 5710 @ 40), (3, 20), (0 ms), DFS >> (5735 - 5835 @ 40), (3, 30), (N/A) >> (57240 - 63720 @ 2160), (N/A, 40), (N/A) >> >> phy#2 >> country US: DFS-UNSET >> (2402 - 2472 @ 40), (3, 27), (N/A) >> (5170 - 5250 @ 40), (3, 17), (N/A) >> (5250 - 5330 @ 40), (3, 20), (0 ms), DFS >> (5490 - 5600 @ 40), (3, 20), (0 ms), DFS >> (5650 - 5710 @ 40), (3, 20), (0 ms), DFS >> (5735 - 5835 @ 40), (3, 30), (N/A) >> (57240 - 63720 @ 2160), (N/A, 40), (N/A) >> >> phy#0 >> country US: DFS-UNSET >> (2402 - 2472 @ 40), (3, 27), (N/A) >> (5170 - 5250 @ 40), (3, 17), (N/A) >> (5250 - 5330 @ 40), (3, 20), (0 ms), DFS >> (5490 - 5600 @ 40), (3, 20), (0 ms), DFS >> (5650 - 5710 @ 40), (3, 20), (0 ms), DFS >> (5735 - 5835 @ 40), (3, 30), (N/A) >> (57240 - 63720 @ 2160), (N/A, 40), (N/A) >> >> phy#1 >> country US: DFS-UNSET >> (2402 - 2472 @ 40), (3, 27), (N/A) >> (5170 - 5250 @ 40), (3, 17), (N/A) >> (5250 - 5330 @ 40), (3, 20), (0 ms), DFS >> (5490 - 5600 @ 40), (3, 20), (0 ms), DFS >> (5650 - 5710 @ 40), (3, 20), (0 ms), DFS >> (5735 - 5835 @ 40), (3, 30), (N/A) >> (57240 - 63720 @ 2160), (N/A, 40), (N/A) >>[...] >> >> Checking on Internet I didn't find a working solution, and the data >> rate stucks to 120Mbps MCS7. >> For me it still a mistery, I hope in your help. > > Note the "@ 40" for all frequency ranges (except 60GHz band).
