DSL Type: ITU-T G.992.3

Still on ADSL2 not ADSL2+

Perhaps her line at 44dB attenuation isn't good enough for ADSL2+ besides even on ADSL2 she could still get up to 8Mbps as the extra frequencies of ADSL2+ are only used to raise speeds above 8 Mbps (I think)

Can you try the other modem?

The 12dB target noise margin is costing speed.

4706 at 9dB
6210 at 6dB target margins

I'm posting from her laptop now BTW.

The thing is it was only when she threatened to leave Utility Warehouse that they finally arranged for a BT Openreach engineer to come out (it was fitted this morning)

TBH iUtility Warehouse don't have good technical support and most of the time she is speaking to an asian guy who doesn't really understand what is going on (a bit like when I was with AOL many years ago)

So to ask them to lower the SNR margin from the current 12 dB to the default 6 dB would be an uphill struggle

I meant to bring over my Netgear router but forgot it

Where are the extensions wired into, now?

She doesn't have any extensions, I made a mistake before.

There's a fair chance it will automatically reduce in a couple of weeks now the crackle has gone. Two steps of 3dB, the second after a further couple of weeks.

Best to just wait and see before having a struggle.

That is assuming this is a WBC ADSL2+ circuit and not a TalkTalk LLU Wholesale, or C&W LLU, or even O2 Wholesale one.

Would a tracert to e.g. bbc.co.uk show whose network was being used?

It would give a clue possibly
