http://serverfault.com – I have internet connection from isp that use mikrotik. So if want to connect to internet I must to login to mikrotik login page. My problem is isp is limiting the login. So if I want my phones, tablet, etc, I must disconnect my laptop first. The question is, can I share this connection within the access point. So my access point is do login and get dhcp address automatically. Then share the internet to all my devices. And I am not must login again. Because the access point have do that. My access point is TP-Link TL-MR3020. (HowTos)
