High signal noise ratio and connection drop outs

Having a problem with FTTC broadband (BT Infinity) for the past few days. Connection keeps dropping out. Quick check of the event log shows 10 or more connection loses in the past 24 hours. It looks like the signal noise ratio is high. Here is an example below...

 

21:07:45, 22 Dec.(94473.950000) PPPoE is up -​ Down Rate=66918Kbps, Up Rate=18169Kbps; SNR Margin Down=10.3dB, Up=9.2dB

 

Can a mod connect with me to see if we can get this resolved?

Re: High signal noise ratio and connection drop outs

the high noise margin is the result of your drops in connection not the cause of them

post stats from the hh5  troubleshooting then helpdesk

try connecting to test socket with a filter and see if that improves your stability

Re: High signal noise ratio and connection drop outs

You should try the test socket as that should be your best connect and eliminates any problems caused by your internal wiring and also a faulty faceplate. This will show if stability problem continues that not in your home and avoid the call out fee of £85

your connection time is only 4 min is that due to manual reset?

Re: High signal noise ratio and connection drop outs

Yep manual reset due to plugging into the test socket as you suggested. The connection stats were comparable on the master socket and test socket. The connection had held for 12 hours before this. Had auto reset several times last night and early this morning.

Could it be a temporary issue has triggered the exchange to re-validate the connection?

Re: High signal noise ratio and connection drop outs

Due to the previous drops in connection you mentioned I did not expect to see any improvement in the stats but by connecting to test socket and leaving it connected to see if that solved the stability problem

the post said you were connected to the master not test socket

with FTTC  it the cabinet and it sounds more like connection problem not a re-validate of your connection

the high noise margin suggests there have been quite a few drops in connection and maybe a rew manual resets to try and fix speed
