I have an Archer C60 v3 running OpenWRT 19.07.7, everything is OK, 2,4ghz, 5ghz etc
I made a test using iperf3 on a notebook and a smartphone connected over 5ghz, both seeing the advertised speed of 433/433mbps, yet iperf3 tests never passes 100mbps
The archer has 5 physical ports, one WAN and 4 LAN that are 10/100mbps
Could it be that the physical port limit of 100mbps affects wireless transfer?
What I do not know.
If we connect a 1 lan port and 1 wan port, in the lan ports of the isp router, they can be added together to now have a limit of 200 mbps.
