      Re: Low Snr Readings

      Am I right in thinking that if the router is plugged directly into the test socket (via a microfilter) a new ASDL faceplate wouldn't improve the SNR ???.

      Again, if I have router plugged into the test socket all the line errors are BT's responsibility ???.

      Looks as though still a lot of errors - see below, only been up for 40 minutes as I disconnected the router by mistake.

      Prior to this it stayed connected for over 24 hours as after reading one of the threads I changed the router channel to 6 and the SNR has stabalised around 8 - 8.5db.

      Connection speed rose back to 15323 bbps and download to 13161 kbps.

      Whatever connection you get with a filtered faceplate will not be better than a connection with the test socket with just the router attached (via a quality microfilter filter - a poor quality component could add noise).

      Yes and no. BT will take responsibility for problems affecting your voice/fax calls. Errors showing in your ADSL stats may have no discernable effect on these.

      Re: Low Snr Readings

      Many thanks for your response.

      I have the router plugged into the test socket via a microfilter supplied by Sky with the router, don't think it's the microfilter as have tried all three supplied and results the same.

      Late last night I saw one of your posts from 13th May and you advised somebody else to report it to BT but to report 'an intermittent fault' which I will do in the morning.

      The speeds were great last night but have dropped a bit today and connection speed down in 14145 kbps on 7.1 SNR with a download speed of 12147 kbps which is still good but could be superb on a noise free line.
