[Business] Comcast SMCD3G-CCR no longer listening on HTTP/HTTPS

Hi guys,

We have a Comcast-owned SMCD3G-CCR modem at work for our Business Class internet and I noticed that I can no longer login to the web interface to view stats and stuff. I tried »10.1.10.1 and »10.1.10.1, as well as our modem's external IP. I did a nmap on it and noticed it isn't listening on port 80 or port 443. I have not had a chance to reboot it to see if it starts listening again. Has anyone else had this problem? I also tried plugging my laptop directly into the modem and assigning a 10.1.10.XXX static IP on my laptop. I wonder if Comcast started blocking customer access to the modem?

Thanks,
Derek

Did you try telnet'ing or ssh'ing into it? I'll agree the web interface should still work, but I wouldn't be able to resist poking around

Yeah, it works, but it asks for a password and my cusadmin username didn't work. Going to hopefully try rebooting it today.

Ok, I was able to reboot it and the web interface started working again.

Its possible a new firmware reset the modem to defaults and it just needs to be set back up, not always but sometimes it happens, its also possible the modem just needs to be rebooted so it redownloads its profile which sometimes does not happen on firmware upgrades because the server tried to send it out while the modem is still negotiating with the cmts and is unable to accept the file at that time, especially with D3 due to bonding adding another step and thus taking longer to get back on line.

I'm having the same issue - the cusadmin login is not working. I've rebooted the router and that didn't change anything.

If you are implying that you can reach the router's login page with http, but the cusadmin password does not work, that is a different situation from the OP's.

What you have sounds like what happened to many of us in May, when Comcast first forced the faulty 3.1.4.51.1 firmware to the SMCD3G-CCR, and then had to revert to the older 1.4.0.49.7-CCR firmware. After the 1.4.0.49.7-CCR firmware was reloaded, many users could no longer use the cusadmin account. The fix was to call support at 800-391-3000 and have a business class tech either rebuild your profile or reset the cusadmin password. If you have a dynamic IP address account, you can probably just do a pushbutton factory default reset on your SMCD3G-CCR (but if you have any port forwarding rules setup, you will lose those with a factory default reset).

Now that you can access the router's admin server again, you might want to check the Firewall Options page. I have seen not having the Disable Gateway Smart Packet Detection "feature" checked sometimes cause the router to lose its http admin server (and also sometimes just lockup in general).

There is no new firmware out currently, if anything it would have been a downgrade if he did not already have 49.7, but that would not have shut off port 80 access. Additionally, the "profile" the modem downloads on each reboot only contains the provisioned speed rates for the customers modem, not the Static IP/Firewall info - that is loaded as a separate config file. Bonding is not "another step", it follows the same upstream lock as described from the UCD says lock onto these channels.
