Query: POC = Piece of crap

After three hours with my DSL provider and the Liksys person we were unable to establish the wireless network. I was told by the Linksys person to return the POC (router WRT54GS) and obtain another POC; and start all over. I uninstalled Linksys, aka, POC. It took another 2 hours to re-establish my DSL back to where I started. Can you spell POC. Shame on Linksys, I am no fool or dummie!
