SNR margin dropping

[#1]

Hello

I very recently upgraded to Unlimited Fibre Extra from Unlimited Fibre and notice that the SNR margin has dropped from around 15db to just under 6db. (Please see attached.) Moreover, the error value in pkts has also been slowly creeping up since I rebooted the router.

I know very little about the broadband technology and so was wondering whether someone could let me know if this was normal? I haven't had any problem with normal downloading and uploading. Is this something that I should worry about and keep an eye on?

Thank you.

Regards

It looks like it's working correctly. You should also have seen the sync speed increasing. The DLM automatically decreases the SNR to increase the speed until it decides that it has achieved the best balance between speed and errors. It can drop as low as 3dB on a good line, mine runs at 3.2dB.
