Query: The product has fatal flaw

My experiences echos those in the review forum - when it works it's great, but the product has a fatal flaw that's pain in the neck. It will drop the connection after 1-2 hours. Need to disconnect the power and leave it alone for at least 5 minutes. Even that does not gurantee the problem to be resolved. Some comments in the forum attribute it to heat. I haven't called Netgear support yet. The experiences from others in the Forum is not great.
