Connection issues

[Alpha13]

I'm having some problems with my cable connection (3 mbs down 1 up) Every now and then I seem to lose my connection for like 5-10 seconds, then it goes back to normal. This started happening last week so I thought it was an issue with party but now I see that it happens with all the sites, plus surfing the web I have the same problem. Any idea what the problem is?

Thanks
