I recently started for the last 30 days having connection problems - maintaining a connection with COX. I called the customer service Tech at COX and was advised D-link pushed a Firmware update that made the DCM-202 not compatable with COX. I attached the email below that was sent to me. If this is infact true I will not puchase any further D-Link products. I have a DGL-4500 and a D-link wireless USB for a laptop. I would have even considered purchasing D-Link NIC's. I have only had the DCM-202 for around 18 months but it's will not stay connected to COX for more than a few minutes. I actually had to replace the DCM-202 with an old Terayen TJ715x Cable Modem I bought from COX 7 years ago... I can now connect to the internet..... COX claims they have notified D-Link about this issue but the Tech said that have not received a reply from D-Link to resolve the issue. Personaly I think this stinks but you can bet I will be buying a new Cable Modem - a Motorola or LinkSys NOT a D-Link

Think you need to post in a different area, This is for the DGL-4500. Are you having issues with the 4500? Sorry that the DLink Modem isn't working. Have you called DLink to talk to someone about this issue? I don't thing DLink would push an update to you with out notifying you. How would they know if you had one or not? Only unless they asked all the ISP if they had any of there modems online. However I don't think that would be practical. Updates to modems I believe are done by the user with support from the OEM. I really don't think any modem MFR would push an update arbitrarily. Are you sure they updated your modem? I would contact DLink and ask for help man. 

Also you have to understand that ISP are always updating and trying to keep up with demand and in the process updating to newer technology will leave behind older stuff. Like DOCSIS, if they update the DOCSIS for some reason and it isn't backwards compatible with the older modems, it's probably not beneficial for HW developers to keep updating. I presume that updating would only get so far before it's just HW design between the older modems and the newer technology that can't be made compatible anymore. I had to do the same thing about 2 years ago. I had a perfectly working Linksys and was told to get a different modem. The old one was no longer supported nor would it up updated. Just the way things are man. I'm currently waiting on another DOCSIS update that my ISP has mentioned, if that happens I hope that the new Motorola 6120 will work. I've been told it will just as soon as they roll the update or what ever there going to do, OUT.

And besides, modems are cheap too, why update something that you can go out and make a new purchase on cheaply. 40-60 gets you a working modem, 60-100 gets you better for those ISP who support them and those blazing speeds. My 2 cents.

Hey furrynutz,

        I heard that its the ISP (Internet Service Provider) that updates your modems. They are the one who update and config your modem, I am not sure about this but yea..... Just thought I should put that out there..

[FurryNutz]

Thanks man, well if ISPs are doing then then issue lies between ISP and DLink and they should have made sure that the update would work and if not then I wold think it's up to the ISP to let user know that there modems will no longer work and they need to update and get different HW. I presume this is what I had to do years back and presume this is happened here as well. This could happend with any MFR Modem, Motorola, Linksys or DLink and others.

[zippoking]

I know that cable modems are for sure updated from the provider, usually automatically on a reboot of the modem.  So if there's an update, you won't get it unless you reboot the modem, so I think based on that its good to do every few months or so, in case there's something they do that maybe boosts speed or prevents errors.

[FurryNutz]

Thanks for some clarification. I wasn't sure. This does seem like that the HW for him and the ISP has probably gone thru a full life cycle and they have updated beyond the capabilities of the DLink modem IMO.

[LookIntoMyEyees]

I am pretty sure that they can reboot the modem at any time they want.

Hello Everyone,

I was surprised there were comments when I came back to check. Thank you for your comments. The DCM-202 worked flawlessly prior to 30 days ago. I did while troubleshooting the problem reset the DCM-202 Cable Modem, it did not help. I built a new system for myself so I also purchased a new Cable modem and a new router this was around 18 months ago. My point is  - as a consumer I should not have to run out and spend money to purchase a new cable modem regardless of changes to DOCSIS even though the D-Link is DOCSIS 2.0 compliant then why does my 7 year old  Terayen TJ715x Cable Modem with DOCSIS 1.0 work??? I did receive a reply from D-Link that I added below. D-Link new there was a problem. I thank D-Link for a prompt response but how can I apply a firware update to a Cable Modem when I can't connect to COX? I would think I would need to send it back to D-Link for the firmware update to be applied? So in the meantime while I kindly sit on my thumbs... someday there will release the firmware fix. If I had not kept the 7 year old Cable Modem I would not be typing this.... I'm sorry but all of the other equipment / devices I purchased 18 months ago don't have problems. I have done some research and plan to purchase a Motorola SB6120 as it is compatable with COX and a Superior product to the DCM-202.

Take Care, If COX is you ISP your screwed if you own this Cable Modem, also I did check the link below and there was no information regarding a firmware fix.

The fallowing post is of my own personal experience as a owner of a DCM-202 and in no way is meant to apply anything else.

I can't go into details, but perhaps I can shed some light on the matter. Cox didn't upload any new firmware to the modems. It was the network the changed, and the modem became partially incompatible with the network. This has something to do with the modem not being 100% compatible with the network to begin with, since the upgrade from DOCSIS 1 to 2, which is around the time they implemented powerboost. The modem wasn't even compatible with Comcast's power-boost at first, and thus the firmware update for the DCM-202 on D-link's website. That change, like this one, came with a "possible" increase in performance. But also, like then, some of the modems weren't capable of the change. The frustrating part is, some parts gave the customers effected free modems. Others gave discounts. I think it had to do with how many were effected, how many of those modems were purchased, and how many leased.


As for the SB6120, I highly recommend it. I also suggest you take a look at your signal levels. The 6120 has a very sensitive tuner, and gave give you a lot of problems unless your signal levels are right on the money. Also, since your area is now DOCSIS 3.0 compatible, you very well may see a performance increase on top of the one you have already received.

[FurryNutz]

Ya figured they changed the  cable system. Happens and the older modems aren't set up for them. I know my ISP is getting ready to do the same I think. I hope i can get the 6120. Hehe.

D-Link has this new statement for the DCM-202

--------------------------------------------------------
D-Link has become aware of a potential issue with the DCM-202
broadband cable modem.  DCM-202 users that are Cox customers in the
Phoenix area that have subscribed or upgraded to Cox's Premium service
may encounter modem problems, including lockup.  D-Link is working
diligently with Cox toward a solution and will provide a fix as soon
as available.
--------------------------------------------------------

[Trikein]

Bett, this isn't just a issue just in the Phoenix area. Is there a DCM-202 forum this can be moved to?

[krkruel]

Is there any plan to release a DOCSIS 3.0 version of the DCM-202, my cable company (charter) said that DOCSIS 2.0 cannnot handle the higher 25MB speeds.
