We had an issue with one AHive at one school.

I have not heard of problems since we set the channels manually. I think
our prob was with conflicts with other WAPs, some outside the school.


Watch it with inSIDder, when they first come up, they go channel-surfing
if they are on auto.

Subject: Re: Aerohive and RF interference


Are all of the Aerohives connected to the same switch? Are you doing any
"mesh" connections?

Are there issues with light use or only during heavy loads?

Does the problem occur all of the time or does it come and go?  If it is
not present all the time can you reproduce it whenever you want? If so,
how do you do this?


You could try disconnecting all but one in this wing and see if that
works fine. Assuming it does, add them back one by one and keep testing.
This could tell you if they are causing each other problems.

I guess I'd try to see if a client was causing it (e.g. by stepping on
others transmissions). Turn off everything you can that is using wifi
there and see if it goes away - or see if you can match problems to a
client coming and going.

We have a wing in our school where Wifi was an issue for some of the
just ended school year.  Thinking it was an AP issue we called Aerohive
tech support and they found that in that wing, the AP's are experiencing
CRC errors above 50% - one exceed 90%. (He said anything below 20% is
OK.) The tech support person attributed it to RF interference from what
he could see.  As far as we know nothing is different in the hallway
from an infrastructure standpoint- including the building, lights, air
handling etc.


Anyone have any ideas on how to measure/monitor the interference to try
to track it down?
