One is that APs are quite far form root the other is that bandwidth is shared among the 3 and the clients they are connected to it and you have spread the collision domain very far so you are getting hidden nodes probably.
So the main suggestion is that you run cable. The other option is to get 2 7731 bridges and make a link, however that one is a bit McGyver style.
Vendor recommendation is wrong!!! 2741 will NOT mesh with 7341. I doubt someone at RW gave you that idea.
Good point, Thank you for suggesting the optimal best solution with the present devices in place.
We checked on ZoneFlex 7731 specs and did not find it much relevant to our requirement.
Question : I the case of running the cable to the two access points
RuckusAP-01 - zf7341 and RuckusAP-02 - zf7341 will the Ruckus Zone Director 1100 treat the 2 APs as Root APs or can there be two more Root APs in the network.
Spoke to vendor he also agreed the option to add in 7341 on mesh is wrong.
