Speed drop after broadband go down - Where should I report it?

goral — Sun, 11 Oct 2026 13:44:44 GMT

My internet speed is 67 mbps – max 73 mbps (there’s no faster option at the moment).
There was a fault last week, and since then, the speed has stabilised at around 40 mbps.
Where can I request a DLM reset? Thanks.

Current data from the router:

	Upstream	Downstream
Current Rate (kbps)	19000	43999
Max Rate (kbps)	30081	73643
SNR Margin (dB)	14.2	9.8
Line Attenuation (dB)	19.8	18.4
Errors (pkts)	1	0

My advice would be to call customer service & select the technical team , they will investigate it , they can perform line tests to check for faults

Locate the hidden test socket that is revealed when you remove the bottom half of the split faceplate (2 screws or press tabs) of your master socket. Only do this if you have a split faceplate. Do you have any extension sockets in the home even if unused? Are there any wires connected to back of faceplate of master socket?

Only if you have an active landline, try the BT Quiet Line Test (QLT), dial 17070 Opt 2, preferably with a corded phone, in the test socket with the router disconnected. If there is any noise, report it to your landline provider as a voice fault (don't mention Broadband). Often sorting out voice faults will fix the Broadband as well.

Reboot the router & plug it into the test socket using a DSL dangly micro-filter. Post the full router stats & System Uptime when plugged into test socket.

Is the issue any better?

@goral Keep an eye on the Up/Down also to see if the DLM is increasing them back up to your normal values also over the next 10 day's, try not to be switching the hub off/on as the DLM may fight the auto recovery.

ask them if theres a fault before asking for DLM reset if yo dont be tempted to do a manual reboot in the first it maybe doing auto DLM as a fault has been registered
