Radio Profiles

rkowals — Tue, 14 Jan 2020 11:01:39 GMT

I have a mix of AP230, AP250 and the new AP650. Would it be better to use separate 2.4Ghz and 5Ghz radio profiles for each AP model?

Radio profiles allow a lot of flexibility. I typically try to do different radio profiles per technology (.n/.11ac/.11ax) but also per different area types depending on your vertical. Classrooms in a school are different than auditoriums, cafeterias, gymnasiums, etc...

Classrooms are my issue, a majority of AP drops are in every other classroom, and usually not straight across from another room. So rooms 1,7,11 and rooms 4,8,12 would get an AP. We mostly do Chromebooks, iPads for students, and the staff laptop.

After creating separate radio profiles, I'm still getting High Interference: I attached a log file to run through if you like

Are the alerts for the 2.4 or 5 GHz frequency?

Are you attempting to utilized the SDR radio and/or a SDR radio profile to flip any unneeded 2.4 GHz radios over to a 5 GHz radio? Your 5 GHz looks rather clean (hears 4 other APs of yours). While your 2.4 GHz radio hears a multitude. With one being right around the -70 dBm mark.

Your show int wifi1 outputs do not show a high % of interference (at least not in the instant in time when you ran the command). It may also be worth noting this post - https://thehivecommunity.aerohive.com/s/question/0D50c00007aiOunCAE/high-interference-alarms-on-ap250 where some HiveOS were flagging high interference alerts when there were not issues related to that.

One thing that can be very beneficial is to limit inter-station traffic if you have no desire for the client devices to chat with each other. At the SSID level you can stop this. This will limit severely mDNS, and other things (Apple Classroom, Chrome Teacher mgmt - or whatever that is called). Some of this is explained in much more detail here - https://getsatisfaction.com/aerohive/topics/updated-official-aerohive-k-12-deployment-guides and https://thehivecommunity.aerohive.com/s/article/Chromebooks-and-WiFi

Doesn't appear that we are using the SRD profiles on any of the past Devices, so it was not enabled on the new AP650's. Most issues are on the 2.4 radio from the alerts.

We do have a lot of Chromebooks, a few Chromecasts and out new Interactive displays, which uses the mDNS. I'll look into the links you have posted.

Thanks

I tried pushing the SDR profile for my AP230 to a single AP, but I get an error the radio profile for wifi0 must be set to default radio (radio_ng_ng0)

Re: Radio Profiles

Two things.

The AP230 doesn't have a SDR radio, so it would not be applicable to any of that. The AP250 or newer would be required.

Secondly the 2.4 GHz radio profile needs to be set to the default radio profile 1st and then the SDR profile should be applied under the SDR profile settings.

Something like the above. With Admin State of Up on the 2.4 GHz interface of course.

It also probably needs to run a certain code base (I'd imagine 8.x or greater).

And what happens is the wifi0 radio goes through it's ACSP process looking for the best channel on 2.4 GHz with the 2.4 GHz radio profile selected in the SDR radio profile. If it sees enough RF, it flips over and goes through ACSP with the 5 GHz radio profile set within the SDR radio profile.

I wasn't allowed to copy a radio profile for the 2.4 using the radio_ng_ng0 and label it for my use. So i had to revert it to using the base radio profile.

Re: Radio Profiles

bpowers — Thu, 16 Jan 2020 03:17:54 GMT

Correct. The radio profile that has to be applied to the wifi0 radio has to be the base built-in radio_ng0 profile. Then within your SDR configuration, you can set an actual 2.4 and 5 GHz radio profiles to be applied based on which frequency the radio operates at.

ok, I'll start making some changes and push it out later today. I'll let you know.
