As to buying a new one, I gifted two out on freecycle since I moved off DSL years ago. Be sure to check into freecycle.org and the free areas of craigslist as there are a lot of DSL modems in closets.
Most ISPs supply the modem+router so why not use theirs?
I'm having a problem with my Motorola 3347 modem dropping my DSL connection every day at 9:00 am. Occasionally it will happen in the evenings (no big problem), but it happens every day at 9:00 am without fail (big problem because my wife works from home in the mornings and must have an internet connection). After 30-50 minutes it will start back up on its own.
I've talked to CenturyLink, our ISP, and they say its a problem in the modem firmware (version QM02-7.8.4r10). They've run a diagnostic on our line and say there has been no interuption of service on their end. Their solution: I need to buy a new modem since they no longer support the one I have.
My question: Is this a modem problem or a CenturyLink problem? If a modem problem, is there anything I can do other than buying a new modem?
