Hi!

I have 4 deco x55, they are all wired to tp link switch and all of them are set in access point mode. However one of them is giving me max 70-80mbps while others providing 180-350mbps. What could be the issue? 

I think i didnt touch any configuration it was just all plug n play, i remember 2 months ago when i set everything up for the first time the speed on that satelite was also 180-350mbps.

Interesting part is that once i unplugg that satelite from switch and once connects wirelessly to another satelite speed goes up and gives around 150-200mbps.

I did test the lan cables and they are all good. Also, tried reboot but no results.
