Hi!
Im new in mikrotik routers. Id like to set up a wifi network with 3 or more APs.I have one one RB 750gr3 and 3 91xG wifi AP.How can I setup the network to have these 3 APs to have the same SSID and the same network?I want to use usermanager+radius for authentification but for all 3 APs the same user and password configuration.The first AP its working fine with userman.How can I setup the 2nd and the 3rd APs to have the same configuration as tha 1st?Still now , I dont use the RB750gr3 because I dont see how it can help in this situation.
Could anybody help me please?I dont need step by step configuration,only the idea how to do this. Soory for my english,its not my native language.
Thank you.

I understand,Capsman.But the RB750gr3 not support user manager.Or…its possible to set one AP to manage all AP’s with Capsman?The AP knows usermanager.
