I have a problem about my internet connection constantly cutting out. We bought a new computer to replace our old one (and there's 2 others in the house). Now whenever the new one is turned on along with one of the other two computers, the internet connection keeps cutting out. I would say the connection goes dead about 80% of the time (on & off) once the new computer plus another is turned on. The second we turn one of them off, the connection immediately goes back to normal. Even with just the new one on, everything is perfectly fine.
So my question is: does this mean I need a new modem to handle the power of the new computer + one of the old ones, or do I need a new router? Any advice would be great (other than "get rid of the new computer & put back the old one" :D)
