I've had routers that after a certain amount of traffic, start failing. And it's not a fail as in a full cut-out dead connection... It'll work for a bit, then flake out, and go back to normal.

ISP provided modems are less than $2 each to them, so the quality isn't that high, hence why they simply replace any that have faults, or any tricky issues.
