Query: Worked great ... for a while

I purchased the SMC 7004ABR router in December and used it for 6 or 7 months until it decided it no longer wanted to hold the connection. The email to customer service resulted in long delays in replies, and responses that did not make sense. Its a shame since it is a good product when it works and the print server feature is nice. Hoping to get it to work, otherwise Linksys here I come.
