Meez: Someone else said wireless. I've explained what happens with my computer. I don't know what else to say.
I would suggest you just post and start over.
From where the internet comes into your place, where the cables run, into what devices it runs all the way to your computer and any other devices you have. Just follow the cable if you need to.
But as othes say, if you can get ADSL its probably better UNLESS you are on a Conklin roadside cabinet (which we may be able to help determine for you if we have an address) where wireless may be better.
