We are wondering if there is a firmware version for the C5’s to allow them to connect to a Ubiquiti AP?
You can do it with a Rocket M5 (really any of the M5 line), but you have to turn off AirMax mode (Ubiquiti Menu (the one on the far left) >> airMAX Settings >> airMAX (Uncheck the Check Box))
It probably would be prudent to Set the RTS Threshold to ‘0’ as well.
You will also have to set the distance on the UBNT equipment. (1.1 times the distance of the furthest client)
Note: I have not tested this, but it “should” work… Probably…
