Re: internet problems
It sounds like you may have nailed the solution- the Cat5 cable between the modem and the router. They don't go bad often, but it can happen, especially if they get bent too much, or pinched. If it still drops randomly after a while, I would first try what Raffaz suggested and update the firmware, or try it on a friends computer. If that doesn't work, I suspect a WAN port (the port that the modem connects to) may be going bad. That router should have a one year warranty, so it may be worth calling the manufacture and possibly having it swapped out if it gives you any more problems.
