I imagined all the wrong things! It was the modem!

A great modem at a great price after $60. in rebates from Circuit City. Docsis compliant all the way to 2.0. Small footprint and no-sweat installation.

Cable modems DO age. I am sure I knew this, but it simply did not occur to me that when my broadband (cable) internet connection began behaving erratically, that a worn, old and obsolete cable modem was at the cause.
I had been using a (very good) Best Data model CMX 110 since connecting via cable a little over 4 years ago. At the time, the provider I used (then, @home) offered a rental for a fee- so I simply bought this Best Data (docsis compliant) one and,until recently, all was well. Then the problems began. Connections dropped. Data light out for periods of time. Calling my current provider (Comcast) didn't help much. They NEVER asked about my modem - simply suggesting that I recycle the power (reboot) it, which I did - and that made things OK - but for just a little while.
I began to suspect something hardware wise. First guess was wrong- I guessed the cable connecting the modem to the computer was faulty (One end had actually separated from the plug a little) - I replaced it - no change. I then suspected that the cable, itself, had been bent or compromised in some way to disturb the signal - I replaced that, too - again, no change.
Then, I ordered a 'refurbished' 3-Com cable modem from an online reseller. It was trash - and, I found out too late, not currently 'supported' by Comcast. Kicking myself for wasting some (thank goodness just a little) cash on this item, I came across an ad for a special (at Circuit City) for the Motorola modem. This time, before buying, I looked more deeply into the Comcast situation and determined that it IS supported by Comcast, and that with the rebates available (totalling $60.), the net cost to me would be $19.99 + tax. I ran over to Circuit City, bought one. Installed it in ten minutes and called Comcast to have it activated. No sweat. And I am please to report that my connection is, again, as I want it. Smooth, reliable and fast.
This modem is docsis compliant to both 1.1 AND 2.0 standards. It is about a third the size of the old Best Data box and has the neat feature of a kind of 'hold' button on top that is used to deactivate the modem when and if you might wish to do so to perform specific tasks on your computer.
I am watching the lights on the modem and smiling as I write this. No blinking - no connection interruption.... and I saved $60. on top of it.
A beautiful piece of necessary equipment at a beautiful price.
