Excellent Line Attenuation, poor SNR

Hi Forum,

 

After a few weeks of fairly regular, short, drop outs and many tests by the Broadband team at EE, but finding nothing, I changed the modem/router out as it was fairly old and getting red hot. 

 

New modem/router installed and all working fine, but I notice that whilst

the line Attenuation is good (Under 18dB) the SNR is fairly bad 

 

  Upstream Downstream

Current Rate (kbps)1900050713
Max Rate (kbps)2335651103
SNR Margin (dB)8.66.2
Line Attenuation (dB)18.19.1
Errors (pkts)00

 

We had Openreach out to replace the incoming cable and wallbox a few months back, so that shouldn't' be the issue. 

 

Any ideas?

There's nowt wrong with a NM of 6dB. It is the usual target. Your Current Rate is almost hitting your Max Rate.

Thanks for the reply. Seems I might be overthinking it then. 

 

Hopefully changing the modem/router will stop these interrupts then.

 

Cheers.

You must be! Attenuation & NM are not related. Attenuation is a measure of distance. NM is a measure of insurance or a leeway against noise.
