Hourly dropouts on Ultra Hub 7

Been having this issue now for about a month and its been reported to Vodafone and they are working on it but I thought to check to see if anyone else has had the problem.

Basically once an hour on the hour I get a 2-8 second net dropout on my Ultra Hub 7. The log was giving this error everytime it happened

[Tr069]TR069 connects to ACS server failed: http error : 401. --check


Now factory resetting the router stopped that message from coming up and it seems to auth fine ( the issue i believe was it was having auth issues ) but the line continues to drop once every hour on the hour. I have confirmed my ONT is fine so its not that and the ultra hub has no issues once the dropout finishes and can hold the connection for exactly another hour.

The only thing thats changed is the month, i've had this issue since the beginning of this month and before that it was 100% stable. I don't know if Gemini is accurate on this but it has said that there have been a lot of reports since the beginning of this month regarding this issue.

As it is happening almost exactly on the hour, I would try to separate three things:

1. LAN/router issue
2. WAN session/auth issue
3. real packet loss seen by applications

A useful test would be a wired device directly into the Ultra Hub for 90 minutes, then keep continuous pings to the router, first reachable WAN hop and something external like 1.1.1.1. If the router ping stays clean but the external one drops at the top of the hour, that gives Vodafone much better evidence.

A quick browser check for visible loss may also help as a sanity check: packet loss test

It will not replace a proper ping log, but it can help show whether short drops are visible outside the router logs.
