[newbie] slow internet connection

[Keldmar]

I have recently got my computer to connect to the internet after a month of agrivation trying to get it to work.  Rather annoying when you find out all you had to do was change the authorisation protocol.  Anyways now that i can connect i am experience slow connections and was wondering if anyone new what the problem might be and how to rectify it.  Any help here would be greatly appreciated
