My Internet connection problem

Lately my net’ connection was seriously on the fritz. Then for about 2 days it was unusable. For some reason it works know,but i know there is something seriously wrong with my DNS.

If i’m not around(on messenger or e-mail mostly) it will probly be the connection… I had suspected factors outside my computer becuase on our external wireless reciver setup,sometimes the connection would be really crappy. And inside the computer…nothing seemed to work.I got lucky and repaired the connection once though usually the repair option is a joke. It seems as long as i dont break the connection it stays…?

Just so you know.
