Hey guys, ive been having some really annoying internet problems and I am wondering if any of you have any idea what causes it:

My QOS is like the stock market, (quality of service) it goes from 20% to 98 percent and moves up and down like nuts, I recently had the cable internet guy come by and check it out and he seemed to fix it, but unfortunately hours later the same problem popped up again.

I'm not sure what the problem is but maybe the isp is crappy, cox cable...

I'm supposed to be getting 15 mbps, I usually get 3-6

Im supposed to upload 2-4 mbps...usually it does 1.7mbps up


I bought a brand new router, which helped...but the underlying issue is the quality of service being garbage.

Anyone else had/have this issue before?
