Ok, still having issues. The router has been replaced with another (same model). I've tested every cable and cable-run on the job and they passed (wiring and speed test with a Validator).

The modem has been swapped for a Motorola surfboard and it works fine connected directly to the PC but when I run it through the router, the network has to be reset daily. I'm heading there tomorrow and I'm going to swap the router for a linksys model.

Tdurrant made mention of setting the router to reauthenticate more often?
