Some of our 702w APs in a single building is having random latency and packet loss. 702w AP in the other building are all working fine. I was suggested to upgrade firmware version first then trying out other actions if this suggestion fails to solve the issue. By default, the channel assignment method for all of our APs here are automatic. I tried changing the 802.11 a/n/ac channel manually which seems to be solving the issue. However the day after, other APs in the same building will be experiencing the same issue. It's like 4 APs with issue every day.
I just found out that when the AP experiences the issue, the AP's interference profile for 802.11 a/n/ac is showing Failed status instead of Passed and the AP is seeing too many Rx neighbors nearby. I am currently working in a hotel and a normal AP is showing at least 5 nearby rx neighbors which are APs on the same floor, top floor and bottom floor. I checked an AP experiencing this issue and saw 18 nearby rx neighbors on this AP and it can even see AP from 4 floors above it.
Now, my first suspect is that the power level of the AP is maybe set too high which is why some APs see it as nearby even though it is n floors away but I checked that the power level are also set automatically.
Can I hear your insights regarding this?
APs with normal ping:
APs experiencing random packet loss and high latency:
what about disabling the data rates? Do you still have enabled the lowest one?
You could try to disable them if not needed due to coverage needs.
Yup, you can kill 12 and 18Mbps since you have a dense deployment. Leave 24 on mandatory.
However, do that with caution for the places where the APs are not so close to each other.
You can design an RF profile that would navigate certain APs data rates per AP Group.
However, I too think, that the signals are not strong enough from the neighboring APs to cause issues.
See if there aren't any rogues or other wireless devices that can be creating that interference.
