Hi tanr, some more information. I have this issue with wireless for about a year now. The problems are not always the same but most time the go around the 5Ghz band of the radio's. I have currently on the FWF-60E: FOS6.2.3 and the 3x221C APs: 6.0.6. But with all versions (6.2.x and 6.0.x) I had the troubles.
What did I do/have: I started with 1 AP profile for 3x221C APs. With all features on: e.g. RRP, Frequency handoff, AP handoff, all channels selected, monitor channel util, etc... I had 3 SSIDs on all AP's and all radios (2.4 and 5).
I had LOADs of problems... mainly due to the following. 2 devices stream ~6-8Mbps continuously (I need them) and took almost all 802.11b 2.4 radio spectrum (again, I had to, they can't do else). What I experienced is that mostly all WiFi equipment will almost always prefer to connect to 2.4 instead of 5Ghz. Thus I had "issues" due to the lack of available spectrum.
That, combined with all the FG "features" that try to steer client to other AP's and other frequencies made the whole situation very unstable. Thus I started to divide the 1 AP profile to 3 AP profiles to be able to select static channels per band (2.4: 1,6,11 per AP and 5: 36-56 AP1, etc.) and I disable all the fancy features of AP handoff, RRP, etc. That made a relief... BUT I still had issues with clients connecting to and SSID selecting 2.4 and not 5 GHz band... (wifi clients can be stubborn :-)).
Thus I decided to create separate SSID's for 2.4 and 5G. I then changed all devices able to talk 5G to 5G and left the other to 2.4. WHAT A RELIEF!!! Everything suddenly started to work as it should ! :-).
And this all the last 1 year with several FOS 6.2.x and 6.0.x.
But now... I have this working situation but this 1 AP that does not want to work with 5Ghz
. I don't see the 5G SSID's when I am around that AP. I do see the 2.4G SSID.
See attached image... 0 clients, 99% channel utilization. nothing helped, reboot AP, reboot FG, disable/select other 5g channels... Thus I ended up in creating a new AP profile and then it suddenly was 0 clients, 0% Utilization.
Thus... I am out of options but to buy ubiquiti :-) (little joke).
