Ohhh 30mb/s is very slow for a device on wifi, especially with the proximity you're talking about.
Iperf3 server on wired eth port of your 7150, and your Wi-Fi client device ( don't feel shy about posting driver info about that Client device) and test with `Iperf3 -c [insert IP address here, no brackets]` Which tests upload, then test with the `-R` switch, which tests download. you may consider kicking off all other clients from your AP first, just to rule out the possibility of a B client blowing up your Wi-Fi speeds, cuz as we know, once a B client joins, it slows the network down for everyone. THEN TEST!
