Internet trouble need tips?

[Blaine]

So I have charter Internet an live in a regular neighbor hood and have recently been having issues with my Internet. It started about a week before the new year. We've had the charter guys out 2 times and in about a week it goes right back to what it is now. So it was working last night and I came home after work to play some 360 and everything is shut down. I can get on my Internet but when I check I can't connect I've powers cycled 3 times and no results. It just randomly
happened and wanted to know if there are any other tricks to fixing this
