Hi all.
My exchange was finally switched over to 21CN today and I was looking forward to a decent speed increase.
My speeds yesterday were 8128 down and 800+(cant remember exact figure) so basically the maximum available speed wise.
Today my upload sync has gone up to 1024, but the down sync has stayed the same.

My router stats.
DSP Firmware Version A2pB025f.d22k
DMT Status No Defect
Operational Mode G.DMT
Upstream 1024
Downstream 8128
SNR Margin(Upstream) 10.0
SNR Margin(Downstream) 8.1
Line Attenuation(Upstream) 11.0
Line Attenuation(Downstream) 17.0


I know the mode is wrong, but adsl2 and 2+ dont seem to connect.

I have tried upgrading from 1.06d to h, no change.

Can't think of anything else to try before I hassle the ISP.

Any ideas?

I appear to be a bit to impatient.
BT switch you onto 21cn equipment but dont put you on adsl2+
Once its been signed off by them, the ISP is told and they ask your if you want to upgrade.

Oh well, hopefully the switch to 2+ will go well tomorrow.

I think it is a case of talking to your ISP.

I'd ensure that ADSL & ADSL2+ are checked so that if anything changes they might connect.

With your attenuation on ADSL2+ you should get anything up to 20meg.

Upstream margin seems high, should I be getting a better upload rate than that?
