Hello,

I recently purchased an EAP245 and placed it in the middle of my flat. But the coverage was not good in the corners, so I bought another EAP235 and place each of them in the opposite corner of my flat.

My flat is not that big, but we have very big concrete walls (Im from germany), so the signal is blocked kinda hard. If I just use one AP in a corner, the coverage is about 70% of the flat.

Now to my problem:

I have a very high channel utilization on one of the APs (EAP235), but it only has 3 clients. First I thought, okay maybe some neighbours are blocking that channel and I switched the channel from auto to 1. Same results, them from one to 6, and again same result and then from 6 to 13 and again, same result. The utilization is usually at around 60-90%.

So it cant really be a neighbour or something else, since then a channel swap should help. 

I downloaded a wifi analyzer app and checked it. On Channel 13 is only my WiFi.

Anyone has an idea what it could be?

Here are some screenshots:

Wifi Analyzer App:

Wifi-715086 is mine. The EAP235 is sending on channel 11, the EAP245 on channel 1.

Thats the EAP 235:

and thats the EAP245:

And you can feel that the channel is busy. We have a babyphone thats sending on 2.4GHz and the connection is bad. Its always loosing signal, the stream is lagging etc

Anyone can help me?
