I'm using a 2700HG-V with BT Firmware 6.1.1.48.1-enh.tm but what is the attenuation? I appear to have 3 different readings. Can you help please I'm a little confused

On the Broadband Summary Page it tells me the down atten. is 63dB (31.3dB UP)

On the DSL Diagnostics - Training History page it says Atten 75.6 (81.6 @300KHz)

So the question is what is my attenuation 63 or 75.6 dB. Any help gratefully appreciated.

With most routers, 63 dB (or in some cases 63.5) is the highest value which the router will report, even though the real attenuation is higher than that. I suspect that the summary page is reporting attenuation the conventional way, whereas the true value is in the diagnostics section.

Another point you may wish to check is the upstream attenuation which is often shown as 31.5 dB but you may find your ISP can give you a more accurate estimate.
A fault I was helping with recently showed 31.5 dB on the 2700 diagnostics page but the ISP reported 45.2 dB.

Kind regards,
Walter

That seems reasonable - thanks for you help.

Thanks for that and I wish it was that simple. I live in France and the information available to the public is limited. There is  a France Telecom database that one can use but it's notoriously unreliable - e.g. they quote a downstream attenuation of 57.47 dB. However the two modems that I tried, that can actually sync, tell a different story with the DG834G v3 reporting 63dB (maximum it can) and the 2700HG-V showing 75.6dB. The DG834G v4, D-link DSL-2640b and the Orange Livebox all consistently failed to sync. With a maximum line speed of 896kb/s (using the 2700HG-V) I tend to believe that the downstream attenuation is somewhat higher than that given by the database. The upstream sync speed is capped at 320Kb/s (although 704 Kb/s is possible according to the  Stats of the 2700HG-v).
