easy 2 points! internet connection question?

[aaaaaaaaa b]

My internet connection is working, but when i try to use the internet it says page cannot be found, and all net apps dont work, saying the connection is down.
i checked adapters, and tried reinstalling them and giving them ip's from ipconfig and all that.
when i repair lan connection adapter, it works, but when i try to repair the 1394 adapter, it does not work, saying Tcp/ip not enabled. Cannot repair, but when i check it it is enabled
what do i do? bridge connections or what?
