		<title>TidBITS: Comments on Aging Cable Modem Causes Performance Decline</title>
		<link>http://tidbits.com/</link>
		<description>It’s easy to blame Internet performance problems on incorrect settings or a corrupted operating system installation, but sometimes the problem really is related to hardware. And even hardware doesn’t always fail in an “it works or it doesn’t” fashion — it’s possible for an older cable modem to just get worse over time without failing entirely.</description>

			<description><![CDATA[This article is confirmation of what I recently went through in upgrading my router.  I am a Verizon customer and my router was the original model Actiontec that was installed about 6 or 7 years ago.  I guess that I complained enough to customer service that they sent me the newest "GigE" model Actiontec router. The computer that is hard-wired into this router is lightning fast but my Netflix streaming (a few rooms away) via my wireless Blu-ray player isn't all that much faster than it was before. My next step will be to hard-wire the Blu-ray in an attempt to capture some of the newfound speed.  You can bet I won't wait another seven years to upgrade my router.]]></description>

			<description><![CDATA[There's another factor, which is that some DOCSIS 2 modems have slow processors or don't do a very efficient job. In some cases, switching to DOCSIS 3, which includes backwards compatibility, can increase performance.]]></description>

			<description><![CDATA[I have a DOCSIS 2 cable modem. I researched into the difference between it and DOCSIS 3. I was sur-prised that the new DOCSIS 3 standard does not necessarily help increase speed unless your provider supports what DOSCSIS 3 does AND you need more upload speed. Otherwise, the difference between 2 and 3 is basically nothing.<br>So those that gained speed from 2 to 3 did so because of the service their provider offers that works with 3. Dumb luck.]]></description>

			<description><![CDATA[Yup.  Happened to me with a router, and with a DSL modem. Both known failures with age.<br><br>Someone told me long ago that most problems with semiconductors aren't sudden complete failure but slow creep out of spec -- the "semi" part drifting toward either the "conductor" end or the dead rock end of the scale, where all the various parts are specified to have their "semiconductor" behavior change in a known narrow range.]]></description>

			<description><![CDATA[As a support person for an Internet server (Rumpus FTP), I can verify that this is a very common problem, and isn't restricted to one brand of cable modem.  I've seen diminishing performance and steadily worsening network problems with a variety of cable modems, hubs, routers, Ethernet adapters and even cables.  It would seem that a network device would either fail or work reliably, but they can steadily deteriorate and I've seen it dozens of times.  If you are having problems, check each component of your network, one device at a time, even your cables.]]></description>

			<description><![CDATA[My experience is that the cable companies use a variety of different brands all the time, sometimes to enable different service packages, and sometimes just because it's what they have around. Apart from asking for a DOCSIS 3 modem, I've never heard of people worrying too much about the particular brand. If you have an old modem and aren't getting the bandwidth you're promised, just call and ask for a new one.]]></description>

			<description><![CDATA[In my particular case, the technician didn't even have to run a test. He had seen problems with that same type of modem many times before. And, when he did run his test, he saw an incredibly low signal-to-noise ratio. I suspect he would've seen a low signal-to-noise ratio even a year earlier, about the time I began to notice the slowdown.]]></description>

			<description><![CDATA[As to point 1, dealing with technical problems as soon as they occur, cable modem degradation is one of those ones where I'd almost disagree—you have to wait for it to get bad enough that the service tech who comes out can truly acknowledge that there *is* a problem.<br><br>If he doesn't, some cable co's will charge you for the visit and/or you can develop a reputation for crying wolf with them.]]></description>
