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:
28-08-2025 20:22:24 | critical | Unicast Maintenance Ranging attempted - No response - Retries exhausted;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,
