Re: [Hub 5] Recurring T3 Timeouts causing intermittent connection drops - Log attached
This post has my screenshots of the broadband quality monitor https://community.virginmedia.com/discussions/Wireless/hub-5-recurring-t3-timeouts-causing-intermittent-connection-drops---log-attached/5681001/replies/5681625[Hub 5] Recurring T3 Timeouts causing intermittent connection drops - Log attached
I am experiencing intermittent connection drops multiple times a week. I have extracted the router log from my Hub 5 and can see consistent critical T3 timeout errors. This suggests a fault with the signal levels or connection stability to the CMTS. Can the VM team please investigate the line quality for T3 timeout issues?
