update: channels 36 and 44 are the only ones being detected by my devices in the 5 ghz with this version.
Maybe this will be helpfully for you:
I had same issue with my c7 (c5) on March image 1.11 and 1.10 firmware. Only channel 36 works, no any other. I reported it on the forum but answer was same: DFS channels need to scan environment. I waited for 60 seconds...and hours... and 5ghz wifi signal did not appear, only 36 worked
I have tried many firmwares: newest stock for c5 and c7, stock stripped, ddwrt, luci and 5g wifi worked properly. Problem was only with latest gargoyle.
I've solved that by adding country code in radio settings. I used ssh and uci commands:
uci set wireless.radio0.country=XX
uci set wireless.radio1.country=XX
uci commit wireless
*XX means your country code
After that 5ghz signal appeared, works stable and it is possible to set other channel than 36. I also checked using "uci show wireless" command if country code is added to radio settings. Don't know why it is so that without country code 5ghz did not work in my c7.
1.11 RC: lets to set country during first configuration, so i chose yesterday my country and 5ghz works ok (i also checked using ssh and "uci show wireless" if country code is added in the radio settings and it is). 5ghz wifi works ok.
