Hello,
I've got problem with wifi download speed. My internet plan is 300Mbps down and 300Mbps up (PPPoE). Wired connection is ok but on 5 GHz WiFi sometimes i only get half of the download speed or less.
When the problem occurs I observe ping spikes to my gateway.
Usually responses from my ac86u to my wireless connected NUC are below 1ms and I can achieve 300Mbs, when problem occurs ping responses can achieve more than 2000ms and there is no internet and then goes down but spike upward to 70ms or more so download speed is limited.
Such situation exist few hours and then ping responses back to 1ms and everything works as it should. I can not find dependency, sometimes 1-2 days is ok.
I was trying to change channels but when problem occurs there is no difference, i also doesn't see any interference from my neighbors (only two of them has got 5ghz ap).
If there are such interference what it could be?
ps. I've restored the router to stock settings also made nuclear reset, changing to Merlin software making m&m setup but problem still exist and I don't know is this broken router or what kind of interferences?

when changing to wired connection everything looks normal. One radio on 48 channel another on 149 channel and ping spikes occurs. So it looks like there is no problem with my asus? If yes what could cause such an interference?
