• Connection via FTP (via transmit.app) sees 2MB/s max download.
• iperf3 (v3.7) (via iperf3 -c <serverIP> -P 10 -t 15 --get-server-output) sees ~7MB/s per connection (~70MB/s SUM).
• iperf3 (v3.7) (via iperf3 -c <serverIP> -P 10 -t 15 --get-server-output -u) sees ~1MB/s per connection (~10MB/s SUM).

These seem low, even for wifi connection.

These seem low, even for wifi connection.

I am not quite sure the way you describe it if there are two or three wifi hops in that path. That is two or three hops on a medium that is half duplex by its physical nature, so that would have to temper your performance expectations IMHO. One of the wifi links may be experiencing more interference than the other. Can you test at the last link prior to going on wifi? If that works, then that clearly points the issue at the wifi portion of the link.

Wifi is best considered a convenience technology not a throughput technology.

Alright, one thing I tried is connecting remotely over internet — I get the same exact speeds.
I feel like I'm not getting the benefit of connecting via LAN when I'm at home.

(Server is running openVPN but I thought I bypass that automatically when connecting on LAN.)
