Broadband connection monitor?

DSL uptime: Only 11 hours 21 mins – suggests a recent disconnection or a device reboot. Upstream/Downstream error control is Off – this could make your connection more susceptible to brief dropouts. If the DSL uptime resets frequently and matches the disconnection events you're experiencing, that could mean the device itselt is rebooting or the DSL session is being lost and renegotiated

To confirm it’s the whole hub rebooting, access the event log and filter by terms like SYSTEM, RESTART, REBOOT, or UPTIME.

Log key terms:

• WAN: Internet side (look for "WAN DOWN"/"WAN UP" or PPP events).

• DSL: Line events (e.g. resyncs).

• PPP: Point-to-Point Protocol, indicates loss or establishment of session.

• CWMP/TR69: Remote management, often irrelevant.

• WLAN: Wi-Fi events – only relevant if the issue was only experienced on WiFI

As above.

Also note if there are any Events that match your drop out times?

Thanks to both of you. Yes, I rebooted the router yesterday, hence the short uptime. The router does not reboot during the disconnections that I'm experiencing. Error controls off - I've searched through the BT Smart Hub 2 settings but cannot find anyway of changing that.

However, I experienced a disconnection a few moments ago. Here is what the Internet Connection Monitor (an Edge extension) showed followed by the corresponding part of the Router event log:





Any clues?

The 30-40 second blackout matches the time a DSL line takes to lose sync and retrain. The ARP and DHCP log entries ar probably just the LAN rebuilding once the WAN comes back.

First check the basics: a clean micro-filter in the master socket, no extension phones or Sky boxes etc. plugged in and do a quiet-line test (17070, option 2) for hiss or crackle. Run the modem’s power unit from a wall socket, not a multi-way strip and note whether drop-outs coincide with large appliances such as tumble-dryers starting or stopping.

If you are on a BT Smart Hub 2 with Whole Home Wi-Fi, try an isolation test: plug the hub alone into the master-socket test port for 24 hours and log the DSL uptime counter. If the counter still resets, collect the timestamps and raise a fault with your ISP; they will escalate to Openreach if the copper pair looks suspect.
