Hello Everyone , I need a help.i configured a hotspot server on mikrotik. and it is perfectly running, /
But problem is that when i make a user on the hotpsot server with that user name and passward 2 or more device can connect and can acess internet. Now i need a help that i make a user in server that is only usable in one device and when a id is in use it can not authenticate form other devices.
thanks in Advance. 
Whatever profile the user’s account is using, set that profile’s Shared Users to 1.
Set this to value 1
That meen that only one user can be active with one username&password. 
Problem is on your router @ Asif Chowdhury 
Select Dynamic IP at WAN setting then disable DHCP in your router,
