There are several on this list, including myself, that have been burned by Netgear switches. If resetting your switch fixes a problem, there is an issue with the switch, or the power feeding that switch. Personally, I'd replace the switch, and I'd also ensure it is on a quality UPS.

When I restarted the switch problem went away for a while, but it seems it is back. Could it be faulty switch?
