Apologies for any lack of technical understanding on my part, lately my router has been dropping connection now I’ve noticed the maximum data rate has dropped to 1056/4700 (assuming this is due to DLM from the connection drops). Now I’ve just checked the router stats again and I noticed the noise margin is 28.1dB/15dB. Can someone confirm if this could be causing the issues I’ve been having? I will also dig out the cheap landline to do a quiet line test in the meantime.
Ok so I ran the quiet line test, there was a constant faint high pitched interference noise so I connected to the test socket and tried again, no noise at all. Put everything back to confirm I wasn’t imagining the noise to begin with and it was silent that time. Bit confused, I’ve plugged the micro filter back into the test socket and left it like that just incase and I‘ll see how the router gets on.
Possibly a bad connection between the front and back of the master socket, oxidisation can occur. Use a contact cleaner spray like Servisol Super 10.
The Smart Hub 6A is really intended for a superfast (VDSL) connection, not ADSL. It can be very unstable on an ADSL line unless the distance from the exchange is short, as it can loose connection if there is stray interference from other circuits.
The home hub 4 is optimised for ADSL and less likely to be upset by out of band signals.
The HH5 is still intended for VDSL, so it still be the same as the Smart hub, and may have the same difficulty in establishing sync, in the presence of wide band noise.
just leave the hh6 connected to the filter in the test socket and check to see if that stops the drops in connection. if the line is stable then DLM will start to reduce noise margin and increase your connection speed probably in stages until noise margin gets back to normal 6db
Thanks, so far 12 hours with no disconnects. How long does it roughly take for DLM to recognise the line being stable and adjust the noise margin to suit?
talking days not hours probably 5/7 days stable should start to see improvement
