Access points are not reconnecting after changing IP address to controller

[Anonymous]

we have r310 around our facility and it was working great until we had some changes in our network, 
we have changed the dhcp settings and i had to change the controller's(unlieashed ap) static ip.
after changing the static ip to the new one. 
i noticed that none of the other AP had reacted to the change and one day later all of them showed up as Recover.me wifi.
i have checked each network port to see that theres network connectivity and when i connected with my laptop, i got a ip address from the new DHCP and all was running good.

i have tried making factory reset but the AP just came back to RECOVER.ME

help?
