Cisco 1832 with 99% Channel utlization

[mgerguis]

We have a group of 6 Cisco 1832 access points providing Wi-Fi access for our offices,

1 set as a controller for all, all but one are working acceptably.

tried troubleshooting to figure cause of connection problem until just recently found that its channel utilization is @ 95-99% for 5GHz when no user is connected on that channel, also @ 70% for 2.4GHz with 5-7 connections.

also interference is showing 99% for 5GHz & 35-45% for 2.4GHz 

Would appreciate any help on why this could be and how to fix?

& if it would explain why users are complaining of the Wi-Fi connection in that section of the network.

Regards,

As a workaround you could move to 40 MHz channels on 5 GHz which gives you plenty more channels to avoid these problematic ones.

Have you someone with a spectrum analyser available? With that tool the source of interference can be very often determined.

4 channels?  Who's the "genius" who enabled 160 Mhz channel width?

Talk about "self-inflicted injuries".

[mgerguis]

Currently for this Access Point we are using 80MHz channel width, it is more of testing what could be a solution for this problem. What also missed to mention that sometimes we only need to restart the Access point & all is working ok again on same previous channels that were in use before.

Bring it down to 40 Mhz channel bond and see if it makes things better.

If the 40 MHz don't help (still showing 99% usage), make sure there is no other radiating source nearby, like a 4G inhouse mobile antenna. Always keep at least 1 meter distance between different radiating sources.
