Hi evryone, 

I experience issues with my office wifi. We have 1200 SQM and I initialy installed 15 AP EAP613 working with an OC200.
 

BASEMENT - 4 AP

GF - 5 AP

L1 - 2 AP

L2 - 2 AP

L3 - 2 AP

The wifi is super low and cuts a lot. I have 2 SSID broascasting 2,4GHz & 5GHz. All the APs were originaly in auto mode (chanel, power etc...) I noticed that I had randomly a lot of chanel utilization. After some research I tried many things:

- manualy config aps, with 1,6,11 on 2,4 Ghz chanel choosing chanel according to the nearest AP, 20Mhz, low power > DIDNT WORK

- reduce de number of AP from 15 to 7 > DIDNT WORK

BASEMENT - 2 AP

GF - 2 AP

L1 - 1 AP

L2 - 1 AP

L3 - 1 AP

- Enable 2,4 GHz to only use 5ghz > Still have high chanel utilization on 1 AP, in the busiest area with 20 clients. The things is that sometime I have over 80% and 5 min after 20%
I also have the issue when no one is connected.

I also have WPA AUTHENTIFICATION TIME OUT FAILURE (1K per day)

I'm no expert in this, so if you need more info that could help you help me do not hesitate to ask.

Thanks 

M.
