Bad environment detected on Radio[0]:Channel[11] by AP Garage - WAC740
I am getting this error. Not sure why. Sometimes it goes down, sometimes it does not. Is it RF? Temperature? It is outside (well, in a garage, safe from elements... but not controlled), and curr...
It is clear for your Neighbour AP list that Channel 1, 6 and 11 are congested & the behaviour is expected in this kind of condition.
Below is the details shows that how many ap's are configured to a particular channel:
Channel-1 has configured with 17 AP's, 6 has configured with 10 AP's and channel-11 has configured with 13 AP's and all these are non overlapping channels so you left out with overlapping channels
You can select any channel from these 2,3,4,5,7,8,9,10, and make sure you use different channel for each AP.
Hi,
Welcome to the netgear community!.
We see this kind of alarms when we see more congestion in the channel or more interference in the channel. When we see this kind of alarm we generally see the slowness in the wireless performance. What firmware version you are using on the controller?.
THanks for the reply. I have been around for a long time! Its just rare that I need to fix a problem. I'm an exclusive netgear guy (except for SMB firewall) and never have much trouble.
The controller firm is 6.5.3.9.
Hi,
There could be some intereference in your network, how many neighbor APs you see in your environment?
You can go to the page Monitor->Neighbor AP.
For now we are not suspecting anything wrong in the controller except the environment.
I see 56 neighboring APs. However, some of those things in my list are not APs. For instance, a wifi lightbulb and a Samsung TV. I am in a residential nieghborhood with larger yards.
I did not have this problem with WAC730s. I found a great deal on WAC740s, and upgraded. Perhaps I shouldnt have?
What now?
martinav looks like you have enabled AirQual thats why you are seeing non-WLAN devices.
AIRQUAL is a collection of software components used to perform spectrum analysis in the 2.4 GHz and 5GHz bands which detects, classifies interference of different types of non-WLAN devices like bluetooth, mircowave etc. and provides the formatted information to the user.
You can disable AirQual from configuration -> wireless page. See the attached screenshot.
