Hello, what is "P" and "DP" in 5GHz channels:
I think it's something with DFS and detecting radar but what does P and DP stand for?
https://wiki.mikrotik.com/wiki/Manual:I ... e/WirelessUse of extension channels (e.g. Ce, eC etc) allows additional 20MHz extension channels and if it should be located below or above the control (main) channel. Extension channel allows 802.11n devices to use up to 40MHz (802.11ac up to 80MHz) of spectrum in total thus increasing max throughput.
I would _seem_ DP is DFS-checked channels and P is non-checked.Made some reconfigurations. Looks like it's because of Skip DFS setting.
When Skip DFS Channels is not checked this messages appears in logs and wi-fi interface setup is delayed for one minute:
capfive-MikroTik ST-hAP-AC-Lite3-1: do radar detect for 60 seconds on 5260/20-Ceee/ac/DP(20dBm)
capfive-MikroTik ST-hAP-AC-Lite3-1: radar not detected on channel 5260/20-Ceee/ac/DP(20dBm)
This way one of the APs selects a channel different from 5180 (it's always 5260 in my case).
When Skip DFS Channels is checked it always sets 5180 emmediately without any scan an all APs
