Hello everyone, I have a dsl-ac68u connected in wan mode to the 1Gbit fiber. I connected my pc to the 5ghz wireless network and did some speedtest. I can not exceed 350mbit of speed although with other wifi I reach 600mbit. On the router page it says I'm connected to the pc at 866mbit and the same says windows. I set the channel bandwidth to 80Mhz and left everything as default. How is it possible that it doesn't go faster?
