Question

After talking back and forth between comcast support and D Link support, D Link has offered to exchange my modem even though I know for a fact the modem is working fine, sending packets but not getting a response on your end. They suggested to have you re-register the MAC address on the modem to fix the issue but the comcast rep said that couldn't be done. So im forced to get another modem, to get a new MAC, even though this one works fine. The installer actually left me the wrong account number when he left, so when I assume when he called in the serial #, and MAC on this modem he did it on the wrong account. When i gave support the mac address they said thats the one on my account but they also were showing i had tv service which I do not. Can someone actually get this straightened out or am i forced to exchange this DCM-301 modem, simply because of the MAC.

Thank you for all the replies! I'll try my best to reply to all above.

The original tech whom was here left me with the wrong account #, it was off by 1 number, so I assume when he called in my MAC on this modem it was to that account instead.

When I went online to activate the account and create users it may have caused a conflict in the system. This modem was working superb for about 2 weeks, on my 3rd call to comcast business she mentioned there was an alert on my account stating there is nearby work being done but that shouldn't be effecting my specific connection.

So it was either 1 of those 2 things but I'm not exactly sure which. However I'm happy to report that since that day my connection hasn't missed a beat, 100% uptime before that particular day, and 100% uptime since the issue was corrected.

As a side note:

I did call D Link twice as well who suggested the MAC be deleted from my account and then Re-Added to fix the dropped connection issue they did offer to send me a new modem if that couldn't be done. Since this modem was working for 2 weeks without incident, it is obviously compatible, otherwise it wouldn't of worked period and the technician who did the install would have mentioned that it was not compatible. It might not be on the list, but it certainly works. It is DOCSIS 3.0 and IPv6 compatible also but I have yet to test the full capabilities of this. It may be worth noting that I have a home office and this might be why it was cleared in my particular case, or maybe their list just hasn't been updated yet for all compatible modems. In either case, thank you for all the help and I wish you all great success on your ventures!

Cheers!

So i dont see the DCM-301 listed as compatible with business class. The official list is here:

While you may get lucky with a rep whos willing to push it through, i wouldnt be too optimistic.

Hello CTA and welcome,

Just trying to get a more clear picture of your business internetwork - so please answer the following questions:

1. Do you have a Comcast Gateway (CG) modem?

2. Are you using the DCM-301 as your wireless interconnect only and it is plugged into your CG ?

3. Do you have a Comcast static IP address?

Look forward to hearing from you...

@VBSSP-RICH - I don't think the DCM-301 can operate as a "wireless interconnect", as it is just a standard cable modem. A reference for it on Amazon.com

It is essentially a re-branded version of the Zoom 5341J.
