We are using several wAP ac and other devices controlled by CAPsMAN. The setup is working just fine (most of the time).
I experienced, that the wAP ac devices have some issues with certain frequencies on 2.4GHz module and all 3 chains enabled!
After many tests, my results are like fallowing:
CAPsMAN config: settings
Frequency: blank (auto frequency selection)
With: blank (auto)
Extension Channel: disabled
Tx. Power: blank
Depending what frequency CAPsMAN selects for the wAP ac 2.4ghz module, it is not possible to connect to the Wifi even the SSID is visible.
So, I tested all 13 channels for 2.4ghz band manually with all 3 chains enabled (chain 0/1/2). After CAP is provisioned, I entered the frequency directly in the interface on CAPsMAN. So with channels 2432/2437/2442/2447 I could not connect to Wifi.
After this, I did the same with only chain 0. Now I could connect to Wifi in all 13 channels.
It seems, that the 3 chains for the 2.4ghz module interfer to each other in certain frequencies!!
The wAP ac is really a handy and useful device. But with such Issues not really funcionable.
To verify my doupt, I also experienced some strange behaviour when I did a "Frequency Usage Test" on the devices 2.4ghz Modul. It shows, that the frequencies 2432 to 2447 seem to have high usage levels, like more than 60%. Even there is no device around sending in theese channels!!! When I do the same frequency test with another device (not wAP ac), these frequencies have almost 0% usage!!!
Has someone made the same experience like me, or am I the only poor Fellow?
