I just installed 19.07.1 on a TPLink Archer C7 v2. I'm using it as an access point. The wifi throughput seemed low. In testing things, I tried using iperf to verify only the gige LAN connection. I'm only seeing 100-200 mbit/s. Sometimes it seems to drop below 100 mbit/s.
I've swapped things around, tried different switches, cables, etc. The other machines I'm using for testing can saturate a gigE just fine getting around 950 mbit/s.
For reference if I run iperf over localhost on this device I see about 540 mbit/s, so the box seems somewhat limited.
I've never run OpenWRT on this device before. Previously it had the stock firmware.
If I'm only getting 200 mbit/s via the LAN connection, the wifi speeds for this device will be fairly limited.
I'm not seeing any errors counted against eth1. Nothing in dmesg. dmesg says eth1 connection negotiated as 1000 mbits/full duplex.
Thanks for any help/insights
