Ok cool. I have an Anker on the way to try and it’s realtek based. I’ll report what I get with it.
I can max out my 100 connection and hit 180ish on wifi in iperf. Oddly enough I found that any smb version other than smb1 in fstsb was only able to do 30-50ish on wifi. Wired was fine. Maybe smb2+ is more chatty and the increased latency bogged it down. (I had file permissions issues with smb1 going to a freenas cifs share)
