Hi, 

I have strange problem with conectivity between Archer TX20U Plus and Archer C6. I experienced some strange drops of connection and high ping between adapter and router. I'm not concerned about router connection to the net ( althought i attach pinnging google results) but connection in my flat is bugging me. 

I attach zip where are the results of pinging googl and router at the same time. And when i tried to ping only router results are the same, and mine concern is the high ping on the TX20u and C6 route, is there any reason of this.  Devices are like 10 meters apart from themself in horizontal and maybe 3 meters in vertical.

This are my settings after some tries to minimalize this high ping occurence (2.4 GHZ) : ( transmision : high, bandwith : 20MHz canal: automatic, Type: mixed ) 

and for 5Ghz: high automatic mixed.

QoS is enabled with prioritized Desktop i'm using.

on TX20U ( power saving is turned off) :

Is there any additional steps to minimaze this high latency problem ?

Or should i replace TX20 with router configured as acces point ?
