Just connected direct to master socket. Modem and microfitler only, no phones or anything else. Here are the stats. Effectively no change.

ADSL Link Downstream Upstream
Connection Speed 12581 kbps 1067 kbps
Line Attenuation 16 db 4 db
Noise Margin 6 db 7 db

Upstream speed is what I was given, didn't specifically ask for anything special, and I'm very happy with it.Makes more practical improvement to me than a very high downstream speed.

EDIT:
And again after returning to my normal setup with all phones connected

ADSL Link Downstream Upstream
Connection Speed 12773 kbps 1095 kbps
Line Attenuation 16 db 4 db
Noise Margin 6 db 7 db

You do mean the test socket inside the master socket I hope? The external socket on the master often doesn't show any difference.

If you do mean the test socket then the low speed is baffling.

Yes, I do mean the test socket inside the master socket.

I'm not worried about the speed I'm getting, just idly wondering if ti could be better.

It's definitely very low for the attenuation. For example look at this graph and put your stats into this estimator.

Which version of 834G is it? There is a possibility it doesn't get on well with the BT line cards on ADSL2+.

Says DG834G v2 on the case.

I flashed it with V2.10.09 firmware before the change to ADSL2+.

So that's an AR7 chipset. I think that might be the problem. But getting out of my depth now.

It might be an idea if no-one "chips" in here to start a thread in a forum such as BT Wholesale Implementation or DLS Hardware asking about how it gets on with the BT MSANs. Certainly some "ADSL2+ capable" routers are less than good with them.

It's a bit disappointing that, with a 54dB attenuation, I'm not going to get any benefit from ADLS2+

Have you checked the stats using the test socket as I suggested.

(It would help if you clicked the Reply button on posts where I have replied to you, not just my latest post in the forum - most of which are addressed to the OP. As I generally use Threaded mode it is very confusing and I have to search back to find out what you are talking about. Like to find the stats you mention. Even in Flat Mode, if you read the side headers you will see what I mean. There is a link in them to an earlier post, and if it is always just the preceding post it makes that useless).

Remember that ADSL2+ increases your attenuation by 3dB

Latest firmware for V2 is 3.0.38 (yes that is for V2 despite the 3.x numbering). Might be worth a go.

Mind you, I also have a low sync for my attenuation using a DG834G V2:

ADSL Link Downstream Upstream
Connection Speed 15227 kbps 1085 kbps
Line Attenuation 15 db 3.5 db
Noise Margin 8 db 6 db

Telnet-ing into my router tells me that the ADSL2+ hardware at the exchange is using Texas Instruments chipset (V2 uses a TI chipset), shouldn't be any problem with it but... who knows?

Maybe time to try a newer router - that's where I'm heading eventually, just need to try and decide which one...
