new cable modem, sell old one?

Calvy 4,271 374 July 29, 2010 at 11:24 AM
I've been having issues with my cable modem losing sync for the past few weeks. I had a Charter cable guy out to check my lines, and he had a tech adjust my signals at the amp. I'm getting good signal now, but still losing sync. He did mention that the modem I have often causes problems. It's an old Ambit modem I bought from someone on craigslist several years ago for 15 bucks.

I just ordered a new motorola SB6120 from Amazon and am wondering if I should sell this old one on craigslist, or just take it to my local electronics recycler?

well before you do anything with the old modem, try out the new modem and see if it stays sync'd. If the new one doesn't then the problem is in the lines still.

I would agree.

It would also be unethical and just wrong in my book if you knowingly sell a modem that is broken. If you do sell it please say it could be broken and at that rate its probably not worth much anyways. Most IPS's are going to DOCSIS 3 which requires new hardware not to mention yours is an offbrand and is likely broken. After that recycling sounds like the right thing for you to do. You have gotten your $15 out of it easily.

Agreed. I wasn't out to scam anyone. If I put on on craigslist, I'd gladly mention I was having sync issues with it. But honestly, it's probably not worth my 10 dollars or so. I'm defintely going to wait to make sure the 80 bucks I spent on the Motorola SB6120 helps with my sync issue. But so far it was worth the upgrade anyway, the speed increase is incredible. I went from getting 7Mbps downspeed on dslreports speed tests to 17Mbps on my HSI+ from charter, which is 10Mbps I thought.

Haven't had any sync issues yet, but they were typically worse at night, so I'm not ready to call it problem solved yet.

I would sell it...someone else might be having an issue and a $5 modem is right up their alley!!! (budget)

I wouldn't go free though, someone will come and get it and it will be a waste, just sit somewhere until they throw it away...for $5, whoever gets it will use it or fix it.

I had a very similar situation to you. I was using a Motorola SBG900 wireless cable modem. Connection had been solid for the last 9 months or so. I started having sync issues also where it seemed as if the modem kept rebooting itself. It was very sporadic as to when it would do it.

I call up Charter, Rep tells me over the phone that he did an "advanced power reboot" over the phone. He said "that should clear it up". Works for a bit and then it starts acting up again a few hours later.

I decided to call up Motorola to see if they had anything to say about it. Motorola tech had me log into the modems control panel. I read off some numbers relating to the signal strength to him. Numbers seem normal but fluctuate a little bit. I remember him telling me that anything under 50 was normal, I think I was at 46 or so. The sync LEDs start going crazy and now I'm seeing a reading of 50.5. Tech concludes that the modem is bad. Send the modem back to them via UPS and I get a new SBG901 back from them. Sounds good.

I went ahead and rented a cable modem from Charter since I didn't want to be without a modem until my new one came in. New rented modem seems faster and is not losing sync. Guess I had a bad modem. nod

New rented modem started losing sync after about 8 hours also. Facepalm I call up Charter and they send out a tech.

Tech comes out the next day and starts digging around the cable service box that lives outside the house. Turns out that the tech who installed the service (9 months prior) never crimped the connectors correctly onto the wire.WTF?! Annoyed Signal seemed more stable with the connectors crimped on correctly. In the meantime I'm getting a new modem back from Motorola. woot

Next day, still farking losing signal! Underweather Another tech is sent out. I tell him to swap out the amplifier. New amplifier is put in.

Guess what? Now the signal is rock solid after a week. Installed the new modem this past monday and haven't had any issues whatsoever.

The End. Big Grin

I have a feeling that is exactly my situation.

I've been down this road before with Charter. I had HDTV service through them several years ago, and all was great until a storm came through one summer. Power, phone, and cable were out for days. When everything was finally restored, my HDTV began freezing. I'd be watching Sopranos (back when it was still on) and the damn picture would just freeze until I rebooted the box. Once rebooting, it would do it again. I had 5 different techs out to try to fix it, and each one thought they had it fixed, but the problem would crop back up again shortly after they left. I finally said to hell with them and ordered Dish Network.

This feels exactly the same. I had another tech out today, who was very nice, but basically said he saw nothing wrong except that the head end did not have the MAC address for my new modem. So he got that updated and basically told me he hoped that would do it. Guess what, still getting sync issues tonight.

It always happens between 10pm and 2am. I don't get it. I've been dealing with the support folks over twitter, and I'm just sitting back now to see what they say the next step should be. I'm getting sick of this but I'm not sure I can give up my 17Mbps download speeds Smilie
