The internet was down again when I came in this morning. I power cycled the router and left it for longer than I did yesterday and everything came back to normal. Maybe it was the router that was the problem the other day as well, but I just didn't leave it for long enough before I power cycled the network switch.
We should probably swap this router out to see if the unit itself is causing the problem. Does anyone know if we have a spare or a preffered vendor? If we don't have a spare I'll order an identical linksys unit from somewhere.
