Query: Very Disappointed With Product

Linksys EtherFast Cable/DSL Router with 4-Port 10/100 Switch (BEFSR41)We have had to replace this product twice in one year, so naturally we now have a different router. We read the customer reviews, and went with D-Link.Isn't it amazing though, how it works so well--Linsys--for some people, and not others? My daughter has had hers for 2 years with no problems. Could it be that we bought it from Wal-Mart, and maybe it's factory seconds that they sell? Just a thought.
