Just got a Ruckus R720, and speeds are max 170-220 when one client is connected. (Iphone 11 or Pixel 4.)
Speeds on our Comcast router were over 400 through the floor. Gigabit fiber line going into the access point provides 800-900mb/s.
Tested with Unleashed 200.5 .6 and .7.
No traffic shaping, QoS, or other limits are in place, and the access point has been set to defaults three or four times.
There are no other neighbors in the 5Ghz band and I'm on a corner lot. The only other network is my Powerline Ethernet one at the bottom of the range, and the Ruckus at the top of the range.
Channel width of 80 for the 5ghz network.
Unfortunately this routers it new enough that I don't see a 200.4 firmware for it. Does that exist somewhere?
