CAPsMAN + RBwAPG-5HacD2HnD – 5GHz issues

Sun Aug 15, 2021 7:15 pm

Hi all,

First of all, thank you all for this great forum. There is really plenty of information in here and it’s great to see the community helping each other.

Now it’s time for me to bother you all with my issue. Unfortunately, I have no idea anymore how to solve it.

My “lab-setup” is quite simple. I’ve a HEX POE (RB960PGS) configured as the CAPsMAN and two wAP ACs (RBwAPG-5HacD2HnD).

The config is straight forward without anything fancy:

1. Band-Usage
I’m in Germany and have set the country to Germany.
[admin@HEX] > in wireless info country-info germany
  ranges: 2402-2482/b,g,gn20,gn40(20dBm)
          2417-2457/g-turbo(20dBm)
          5170-5250/a,an20,an40,ac20,ac40,ac80,ac160,ac80+80(23dBm)/passive,indoor

          5250-5330/a,an20,an40,ac20,ac40,ac80,ac160,ac80+80(20dBm)/dfs,passive,indoor
          5490-5710/a,an20,an40,ac20,ac40,ac80,ac160,ac80+80(27dBm)/dfs,passive
          5190-5310/a-turbo(20dBm)/dfs
          5180-5300/a-turbo(20dBm)/dfs
          5520-5680/a-turbo(27dBm)/dfs,passive
          5510-5670/a-turbo(27dBm)/dfs,passive
          902-927/b,g,g-turbo,gn20,gn40(30dBm)
As I’m living near an airport I can’t use the DFS frequencies quite well. So I’m focusing with my config on the UNII-1 channels and following Ekahau’s “guide” at https://www.ekahau.com/blog/channel-pla ... ter-wi-fi/

When I’m selecting basically everything besides the 20 MHz bands at the frequencies “5160, 5180, 5200 and 5220“

e.g. the 40MHz
OF_5_1: selected channel 5190/20-Ce/ac/P(23dBm) (fixed)
WZ_5_1: selected channel 5230/20-Ce/ac/DP(20dBm) (fixed)

Or the 80MHz
OF_5_1: selected channel 5210/20-Ceee/ac/DP(20dBm) (fixed)

Everything shows perfectly in CAPsMAN.

But the devices are not broadcasting at all:

Only when I select one of the 20MHz channels, I can see everything broadcasted

But :) this brings me to my other issue:

2. Connecting to this SSID
When I have selected one of the 20MHz channels, I cannot connect to this SSID at all. I’ve also tried to connect with different devices. But absolutely no luck. I can see the SSID, but no chance to connect.

I’ve tried some debugging to see what the issue might be. But I can’t see anywhere any logs (after changing the wireless logs to debug in the log config - https://wiki.mikrotik.com/wiki/Manual:System/Log). Not on the CAPsMAN, nor on one of the APs.

The identical configuration "of everything else", but only on 2,4GHz works perfect.

Has somebody any idea what I’m missing to get 5GHz up and running?

Thank you all in advance!
