No ipv4, only ipv6 with Motorola MB8600

I have been using a Motorola MB8600 for a few months, and recently moved it to a new room in the house. 

 

After hooking it up again, I only receive an ipv6 address, and cannot reach any address on the net. Here's a snippet from the modem log. 

 

Time Not Established Critical (3) SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing;;CM-MAC=<<redacted>>;CMTS-MAC=00:00:00:00:00:00;CM-QOS=1.1;CM-VER=3.1;"
Time Not Established Critical (3) No Ranging Response received - T3 time-out;CM-MAC=<<redacted>>;CMTS-MAC=<<redacted>>;CM-QOS=1.1;CM-VER=3.1;"
Time Not Established Notice (6) Honoring MDD; IP provisioning mode = IPv6"
Fri Aug 3 12:05:58 2018 Notice (6) TLV-11 - unrecognized OID;CM-MAC=<<redacted>>;CMTS-MAC=<<redacted>>;CM-QOS=1.1;CM-VER=3.1;"

 

Spent hours with a technician at the house. Reprovisioned the model multiple times and escallated up to tier 3 service for help. 

 

Eventually, reverted to the Netgear CM700 that I was using previously. With that modem, I receive both ipv4 and ipv6 addresses and am able to browse the web. 

 

Go figure. Any ideas? That MB8600 had been working well for quite a while.

Re: No ipv4, only ipv6 with Motorola MB8600

Did the rep say that they can see the 8600 when it is connected to that outlet ? What do the modem's signal stats look like when it is connected to that outlet ? 

Besides those error log entries, please also post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

Not sure what the problem is exactly but FWIW, that error log message that states 'IPv6" is only for the DOCSIS WAN managerial side of the modem and has nothing to do with what the modem bridges to the LAN. It simply means that the ISP (Comcast in this case) uses only an IPv6 IP address to talk to the modem for backend management purposes.

Re: No ipv4, only ipv6 with Motorola MB8600

Hi,

 

They could see the modem, and reportedly, the line looked wonderful from the back end. 

 

One of the problems they had was that, although they reprovisioned the modem several times, and even deleted and rebuilt my account, the model kept falling back to the walled garden mode.

Re: No ipv4, only ipv6 with Motorola MB8600

I think there were a couple of problems here. The MB8600 was in some sort of strange state, and kept going back into the walled garden state after it had been provisioned. Rebuilding the account probably fixed that problem. 

 

The modem, on its status page, reported only an ipv6 address, but that report wasn't a real problem, only confusing. A MacBook plugged directly into the modem could get an ipv4 address over DHCP. 

 

The real problem was the Synology router. It, like the modem itself, obtained only the ipv6 address. 

 

A Google WiFi router was able to obtain an ipv4 address just fine when plugged into the modem.

Re: No ipv4, only ipv6 with Motorola MB8600

Is that the latest screen shot ? If so, the modem is still showing that is has a "Walled Garden" bootfile";

It needs to have a regular bootfile for your speed tier......

After reprovisioning and switching back to the Motorola, the profile now reads: d11_m_mb8600_blastpro_c01.cm

Re: No ipv4, only ipv6 with Motorola MB8600

O/k now live with it a while and see if you still have any problems.
