Here are a few relevant points. I'm wondering why there is such a difference between radios. Loudest neighbor is -64.

 

sh int wifi0 - High Collision

Noise Floor -95

CRC error rate 0.00%

sh int wifi0 _count

42% rx CRC rate

 

sh int wifi1 - Good

Noise Floor -95

CRC error rate 0.00%

sh int wifi1 _count

0% rx CRC rate

Average client count per AP?

Type of clients?

Is dynamic channel switching enabled?

 

That is quite of bit of CRC on 5 GHz.

Do you have an AP in each classroom?

Here's the same data pulled just now. The above image is from last week.

It's not on the same channel. I'm fairly vigilant when it comes to co-channel interference. That's partly why I'm so stumped on this.

I took data from another site and the data below is what I'm seeing. All AP250's running 10.0r7a with dual 5Ghz radio config.

I can't seem to find any coordination between why some are so high and others so low, even on the same AP. These are all similarly designed classrooms. I'm planning to collect more data from these same devices to see if I can pin anything down.
