please can any one tell me how can i connect multiple devices to it. as when i try to connect my andriod phone to it the same login page appears and after entering the username and password, it fails connect and shows the error message that this user can not have more login sessions.

Thanks in advance.

You need a router to share the connection, replacing the access point with something like a TP-Link TL-WR841N 300Mbps Wireless N Cable Router should do what you need.
