I've been having problems with my internet connection. My connected to a router and my internet connection is DSL. When I start the computer the connection is normal. Then after a couple of hours, a window pops up. It says to "Connect to KT" (KT is my ISP). In the window, it has a box for a my logon and password. Usually I just cancel it and I'm still connected. Lately, when I cancel it my connection stops. Its weird though, only my browser seems to be affected. On Firefox and IE, I can't access any page. On the other hand, my Instant Messenger and Skype are still connected. Also my network icons says that I'm still connected to the internet. Anyway, when I click on connect. It gives me a message about failing to establish a connect and something with an ERROR 815. I heard from somewhere that it might something to do with the WAN PPPOE. The same thing happens when I'm connected to a public WIFI hotspot. My OS is Vista Home Premium.
