Internet Connection?

[Joey T]

It could be a lot of variables that you yourself are unable to fix. Questions that you need to answer are :
1) What kind of connection is it?
2) Where is it located?
3) What kind of connection do you have to your computer?

Some of the underlying problems would be :
1) Can it be the modem's fault?
2) If you have a router, could that be it?
3) If it's a landline DSL, can it be a phone line issue?
4) Is it your network card not responding?

It's SO many questions that we cannot answer. You're better off calling your service.
