Yesterday I connect zf r300 to another router 1 and second zf r300 to another router 2 and zd to router 1, and all worked good. But today when turn on zd,zf and connect it again it didn't worked. If i connect zf direct to controller zd it see AP? 
please clarify. 
thank you

Daulet. What IP addresses have you allocated to the Ruckus hardware ? Have you fixed then ?  Have you check for conflicts across the address range. What routers are you using ? I'm asuming you have setup a VPN between both sites, please confirm .
