Slow download/upload speed on Archer C7 v5
Hello, I have an issue with my Archer C7 v5.0 which is running the latest build 1.1.3 build 20210519 rel.50598 where download/upload speed are lower than what they should. I have a fiber connection with 650 mbps speed and the maximum speed I get when I am connect to the router is 450 mbps for download and 350 for upload whether it is running in router or access point mode and even when I disabled parental control and QoS also when I tried all possible 5ghz channels. Please note that I get the full speed when I use the cable. The Wifi is unstable in general and sometimes I see packet loss when I am testing the speed. Please help me fix this issue
