Hey, so I finally set up my new wireless modem.. Thats a good thing, everything is much faster.. but now the thing is, my Macbook keeps disconnecting from it.. Even when I connect my Macbook to another connection through a router(for downstairs) it connects and disconnects..goes on.. But now a few minutes ago, I went to System Preference > Network, then it showed me that I had to enter a user name and password for the router..Which is something that NEVER happened..and I had to also tick PPoE I will take a screen shot and show you guys what I mean.
And what I have circled on the picture is something that appeared =S and when clicked on it says
Connceted:PPoE
Disconnect
Airport with a check beside it
