Exodus Box Problems

[BackPackHunter]

I have an Exodus box that's driving me crazy
It buffers almost as much as it plays , I was told my internet wasn't fast enough so I had telus come on Saturday to upgrade the internet (fastest available in my area) seem almost worse then before ...
Why is it buffering all the time? Is there something that can be done? Is there background programs slowing it down? Do I have a bad box?
I'm very lucky to get 5-10min of play time without buffering

Any idea?
