Internet drops out almost every day

Hi,

 

Since upgrading to the new GIG1 package, our broadband has been dropping offline randomly, mostly in the evenings. Sometimes it takes a good 10 minutes for it to come back online. This is becoming so often that we're becoming frustrated as a few of the important devices take some time to come back online.

 

This imapcts WiFi and hardwired devices.

 

The modem logs state the below when this happens:

Unicast Maintenance Ranging attempted - No response - Retries exhausted;CM-MAC=MAC1:HERE;CMTS-MAC=0MAC:2HERE;CM-QOS=1.1;CM-VER=3.1;

16 consecutive T3 timeouts while trying to range on upstream channel 8;CM-MAC=MAC1:HERE;CMTS-MAC=0MAC:2HERE;CM-QOS=1.1;CM-VER=3.1;

Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=MAC1:HERE;CMTS-MAC=0MAC:2HERE;CM-QOS=1.1;CM-VER=3.1;

Looks like there's some issues with the maintenance attempts. 

 

Can someone please look into this and ask the relevant team to resolve this issue?

 

Thanks,
