Ruckus PHY Errors?

[Quackers]

Can anybody tell me exactly what the PHY Error is measuring? Were having issues in 1 area, and the AP in that area has lots of PHY Errors, like 9000 of them on the 2.4Ghz and 500 on the 5Ghz, yet the surrounding AP's have like 24 or so errors which is a lot lower. Just want to know what it means.

Hi @Quackers PHY Errors ( Physical Layer Errors) are collisions of data in the air.

 

The high number you've received suggests a high level of interference in that area this could be down to, hidden node issues, large number of legacy 802.11b clients around the AP (with hidden node issue), or even a bad WNIC causing Layer1 or 2 issues in the air leading to the collisions.

 

The best starting point is to look at the AP that you're having lots of problems with, check the area, look at AP mounting placement and review whether to change the AP channel, perhaps move the AP to a new location and check your results again. If you're still having problems it could be down to a client issue. If it continues to cause you problems it's best to get a wireless consultant in to review your network. We can offer this service if it was of interest at the end of your investigation.

Just as a delayed thought...would the APs you're receiving the high PHY rates with be the 7363 APS you're having problems with?

 

If so, have you tried swapping the APs with some in a different area of the school? This would let us review whether it is the area, or the AP that is causing you a headache.

You need to read the physical errors in conjunction with the total frames received. Is it possible the AP with higher physical errors is also processing more traffic?
