I have a college LAN connection that opens up a login page in my laptop immediately as the LAN cable is inserted into the ethernet port. All was working fine till yesterday's night but since today the login page is not opening up, though i'm being shown connected to the wired network.
But when i connect to a wifi network and open Firefox and click on
click here to login to this network button i'm redirected to a login page and i log-in successfully.
I've come to know that some of my batchmates change their mac addresses and some use VPN ? Could these be of any help.
Thanks in advance.
