My ISP is Comcast. Earlier this week or late last week I got a letter from them saying they were going to send me a new modem since they're going to be upgrading their system and supposedly, my old modem won't work with DOCSIS 1.0. I don't rent a modem from them so I called. They said they send the letter out to everyone that uses Comcast but that if I had an older modem I'd have to get one that was DOCSIS 2.0 compliant...whatever that means. I found out my Toshiba PCX 2200 is not compliant so I guess I'll have to get maybe a Linksys GM-100 that is DOCSIS 2.0 compliant. Trouble is my router(Linksys BEFSR41) is about five years old and don't know if that too will need replacing. Anyone know if this is going to be another expense or will it still work with the new modem and Comcast's new system?
