There shouldn�t be .... but something�s awry.

Can you clarify how the extension phone are connected, are they wired to the back of the removeable faceplate? If not you could have problems.

Doesn�t actually apply to the nte5c. Need to ask now if removal of lower faceplate stops dial tone on extensions

Yes removal of lower plate drops phones and speed test in this condition still gives 62Mpps. Quiet line test is perfect as well, always has been.

Recently re-contracted and the email suggested full speed with a guaranteed 73Mbps. It was this that prompted me to post my question. After a congestion problem was sorted out about three miles from our exchange connection has been steady with no drops. Router reboots every 14 days but this I understand is normal.

The sync speed isn't going to magically change right away because DLM is controlling your line. You need to look at the line stats for differences.

Are you suggesting leaving lower plate disconnected for a time and check router stats then?

Thanks to everyone for help and suggestions.

No, I'm suggesting comparing the line stats before you disconnect the lower faceplate with the line stats after you've disconnected the lower faceplate.

Is the phone noisy to use? (Hissing, popping, crackling)

No, quiet line is perfect.

Very little difference with lower faceplate connected or disconnected.

Data rate 19999/66860 same

Max rate 23078/68520 23090/68593

Noise margin 7.3/6.3 7.2/6.3

Line Attenuation 7.6/9.5 same

Signal Attenuation 00/00 same

I think that is just normal variation?

Is this looking more like something outside of the property?
