The thing is that I'm living in hostel and they use cisco router with web authentication. Normally after successfully connected to the network, I've got to enter name & password at the browser (126.96.36.199/login.html) to get redirected. However, the problem is now is that when connecting to the router, I always get the IP like 169.254.x.x which is not correct, no DNS server and no DHCP server as well. Normally DHCP would be 188.8.131.52 . Can help ?
