I've had recurring latency spikes for approximately one - two months. The BT Smart Hub has already been replaced and the fault persists. This is an intermittent latency/jitter problem rather than a loss-of-sync problem. I need the fault escalated for investigation of the FTTP access/aggregation network, including congestion, packet loss and routing during the affected periods. Please don't close the fault based solely on a point-in-time line test because the problem is intermittent. the internet keeps dropping out almost completely.</P> Sat, 19 Sep 2026 11:26:01 GMT Lucas1738 2026-09-19T11:26:01Z https://community.bt.com/t5/BT-Fibre-broadband/Ping-spikes-through-out-the-day-and-is-perfectly-fine-most-of/m-p/2470876#M366704 <P>I'm on BT Full Fibre.

It would be useful to know what type and speed of broadband you have, other than passively observing latency how you are measuring it, does the issue happen at any specific times, and is there anything else going on in the home that could cause usage spikes (which then cause latency)?</P><P>*Not using the BT router here, but if it allows external devices to "ping"&nbsp; it's WAN (reasonably* safe) have you tried using a tool such as the Think Broadband BQM (Broadband Quality Monitor)?</P> Sat, 19 Sep 2026 15:13:35 GMT https://community.bt.com/t5/BT-Fibre-broadband/Ping-spikes-through-out-the-day-and-is-perfectly-fine-most-of/m-p/2470888#M366709 Crimliar 2026-09-19T15:13:35Z
