Do cable modems degrade over time? I've got a Motorola Surfboard that we got in Jan of '03 when we got Road Runner. Lately it's been acting like a bitch and constantly needs to be turned off/turned on whenever I'm moving a lot of data (UL and DL). When all the problems were starting with this (like it will kick me offline and i'll have to cut power to the modem and let it stay off for 2 or 3 mins then turn it back on) it would kick me off when i was ULing 200-300Kb/sec and DLing like 500-600 Kb/sec. it's gotten to the point now that i had the cap set at 200kb/sec for DLing and it even kicked me off of that just now so I had to reduce the DL cap down to 100 kb/sec. So the amount of data that i'm moving keeps getting less and less for it to kick me off, if that makes sense.
I called my cable people and they were supposed to call me back but those motherfuckers never did so I'm gonna call again tomorrow. They said that they would replace the modem since it was theirs but they never said what model they'd replace it with. At work they sell the newest Motorola Surfboards for $59 and I get 10% off of that. So if worse comes to worse and they wanna replace it with some bullshit modem i can always buy a new one.
but my question (and the point of all this) is this: do cable modems get crappier over time and lose their "speed" and become slower and have a less and less of a top DL/UP speed over time? Hopefully this made sense. If not, let me know and i'll try and explain better. thanks guys.

Cable wiring and connections deteriorate over time for many reasons.
It's very possible that your signal strength has deteriorated to the point where the cable modem isn't getting what it needs to operate properly.
The cable modem actually needs better signal strength than your TV set does.
Also, splitters, and even signal boosters, can adversely affect cable modem performance.
I would make the cable company come and check everything out before spending money on new equipment.

I just noticed this thread. When I got cable internet at my old house at first it didn't work very well. They had to bury a new cable to my house and the problem was solved. The house was built in the 1970s if that helps.
The person who comes on tuesday will probably check the strength of the signal and get everything fixed.

Don't forget that a cable modem network is SHARED BANDWIDTH.
As more customers get on your network segment your share of
the available bandwidth decreases.
I don't know your situation, but if they just built a 50 story
high rise across the steet ....
DSL has dedicated bandwidth to the central office switch. I'm
not advocating DSL over cable, just pointing out the difference.
Also be aware that cable companies monitor usage, so your cable
company maybe throttling your bandwidth.
Does your upload/download start off fast and then slowdown?
That's a dead giveaway that the cable company is setting a
bitrate limit.

I can feel your pain. Just had a month-long fight with voip provider and cable provider about intermittent slowdowns in service. They kept having me reset crap all the time and replace equipment and rearrange my network until I documented lost packets in ping transmissions in THEIR end of the network - my brother suggested it - THEN they decided to send out a tech. Turns out the original tech who installed our cable couldn't use a tape measure and had actually installed four (4!~) connectors in a 3-foot length of cable near the pole. after 5 years the weather had finally gotten to it and corroded the connections. This is after they replaced the cable-modem and the voip router.
Why did I have to spend over 5 hours total on my cell phone following inane advice from three different levels of 'tech support' and STILL no-one could tell me how to isolate the problem to one side of the network to the other?
Good luck.
Edited cuz I can't spell
