Range Extender - HOTSPOT - URGENT CASE

Hi All,

i have Mikrotik Router RB 2011UiAS-2HnD for hotspot server.
there is access point installed on the network (HOTSPOT NETWORK) i’m trying to extend this access point signal by installing LINKSYS N300 Access Point but each time i’m going from an access point to another it redirect me to hotspot page again and ask me for login again.

need to solve this issue asap…
