Over the last 6 months I have had 3 2Wire modems go bad. I aws told that they are out of warranty and I would need to buy at $100 each. Let's see. One recieved July 2011, One recieved Dec 2011. They seem to only have a 30 day warranty. How do I know they are bad? I replaced them with Motorola 2210-02 and D-Link wireless router and now have what I payed for.
