Hey @Tigerg,
 

Intermittency can be incredibly difficult to deal with to say the least! Thank you for providing your modem details, basic signal wise everything looks good. The Mac Domain Descriptor timeout isn't a concern though as that's more or less a note than it is a warning. The MDD is transmitted every couple of seconds on the downstream channels and if there's an excess of them dropped the timer expires and it begins looking for them again. 

One off's like these can occur for a number of reasons but there's no indication as of yet that it's pointed to a connectivity issue. 


Would you mind confirming for me what occurs with the light pattern on your modem when the connection drops? This could give us a better idea of what's occurring.

I've been here awhile

The light on the modem looks normal, one light blue one dark blue.

 

When the MDD timeout, I can not connect to internet and all my connection disconnected.

It takes 30 sec to 2 min to get internet back.

I plan to stick around

To me it looks like the signal strength dbmv are too high.  Possible some type of configuration error with coax splitters etc. Maybe @Datalink can provide some assistance with this one.

I have the same Error along with other Errors, Rogers sent 4 technician so far and they checked all the cables and removed all splitters inside the house, they also replaced the modems 4 times and the Errors still the same.

Re: Lost MDD Timeout every 7 mins for 4 weeks

Hello, @Eelsisy.

 

Thank you for joining this discussion; intermittent connection can be quite disruptive.

 

We can look into diagnosing the issue for you. To get a better understanding of the problem, please answer the following:

  • How often is the connection getting dropped? 
  • When was the last time you have lost the connection? 
  • When the connection is lost, is the modem rebooting?
  • Can you provide the LAN and WAN up times? It's listed under the Status menu. 

Cheers,

RogersMoin

Re: Lost MDD Timeout every 7 mins for 4 weeks

I have the same problem, and I've had multiple technicians and endless hours on a hopeless support line

 

Tomorrow I'm supposed to be getting my modem swapped.

 

It's been almost 6 weeks of intermittent Internet use with the Rogers ignite business plan.

 

Tomorrow I have a call at noon with Bell Canada to put in Fibe.  I'm hopeful between these two clowns (Bell/Rogers) I'll at least have one Internet access point working.

 

Final note, not sure who Rogers uses as outsource technical support but these guys are beyond hopeless.

Re: Lost MDD Timeout every 7 mins for 4 weeks

@Duffy_YYZ if you haven't done so already, with previous multiple tech visits, you should be asking for a senior (real Rogers) tech.  He or she should be able to solve the problem, or call in a maintenance crew.  Assuming that you're in a house, how long has the external cable been place?  Has it been replace during any of the tech visits?
