Access point is powered by a wall adaptor. Gigabit connection is coming in at 850m/850m as tested by a Thinkpad immediately before plugging the tested Cat6 into the r720.
Using the Unleashed firmware 200.6 or 200.7:
-250m/500m in speedflex using no password, visible SSID
-50m/100m in speedflex using no password, hidden SSID
-160m/480m in speedflex using WPA2, visible SSID
The best case scenario is not secure at all, and still has the issue of download speeds being severely limited. I should have a PoE injector from Ruckus soon to test and see if that makes a difference. Right now no QoS is enabled, 80mhz channel width on 5ghz with no overlap with other networks, the microwave is not running, and I'm in the same room as the router with clear line of sight.
The second ethernet port is used to connect other devices, but when I remove it the speeds are the same.
I've disabled 802.11g clients and made sure nobody else is on the network and the results seem to be the same.
On iPhones in particular (iPhone X and iPhone 11), the speeds are even worse than what I'm getting on a OnePlus 3T from 2017.
I'm going to try the oldest standalone software I can find when I can to see if it has issues. If anyone else has these same issues feel free to comment or post your workaround here.
