Re: Slow Internet - mods please assist.

I wish BT Wholesale would just make things like current line target noise margins and line profile band clearly available to customers via the speed checker or modem stats. Would save a lot of guesswork!

The OP had though I think overridden the target down noise margin using the alternative modem-router options.

Might be best to try the HH5 in the test socket and see what noise margin and connection speed that sync's at.

Re: Slow Internet - mods please assist.

Or did I read that wrongly?

Does the Billion have an auto noise margin selection option that might still override the DLM set target?

Re: Slow Internet - mods please assist.

the Billion does let you select a % reduction but I don't think you can actually select a noise margin

 

trying from test socket will help with new stats

Re: Slow Internet - mods please assist.

Right tried from the test socket and no difference at all.

The Billion is on auto SNR - should I just set it to a target of 6?

I have tried with the HH5 too and that was no different but the Billion has lower attenuation on the line compared to the HH5 and the Internet connection is more stable. When running a speed test the HH5 would peak at the start and then drop off rapidly. The Billion just has an almost constant flat rate of transfer.

Re: Slow Internet - mods please assist.

Pity you didn't stay in test socket and post stats whether billion or hh5. Need to select either but then connect to preferably test and stay there for at least 3 days to show connection stable

Re: Slow Internet - mods please assist.

Both the Billion and HH5 were stable for several days or more at a time without reboot.

 

 

So what should I do next I am a little confused.

Re: Slow Internet - mods please assist.

Connection down rate is now 2400kbps which shows that the connection speed is not being limited by the up to 2272kbps band. Just coincidence before I guess and imjolly was right. 🙂

Something else causing the lower connection speed compared to what you used to get.

It also seems to confirm your DLM target noise margins are the normal 6dB, though I'm not sure exactly what the Billion auto setting means.

Do you know if the attenuation is the sane as it used to be when you got a higher connection rate? Also what about the interleaver and INP values?
