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

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).

I'm sorry if I have caused any confusion - I didn't think I had replied to an inappropriate post at any point. I will retire from this thread at this point - to clarify, I don't actually HAVE a problem that I am trying to solve and the comment about ADSL2+ with a 54dB attenuation was just an observation - I do not have an ADSL2+ connection and there seems no point in my attempting to obtain one.

It's OK, but it does make things difficult.

If you have attenuation of 54dB on ADSL(1) then that would rise to about 57dB anyway on ADSL2+ . You may find these two links useful:-

Where you could gain from an ADSL2+ service would be if there is one of the good LLU ISPs at your exchange, as higher performance is usually obtained than on BT Wholesale based lines even at similar speeds, because of the different systems used.

I suggest if you want to find out more you start a thread in Which ISP with full line stats and the link to what samknows says about your exchange. See the Useful links page on my website for samknows and help finding your stats.

Thanks for all your help and suggestions.

I think I'll leave well alone for now. The speeds I'm getting are fine for my usage and the last time I flashed the DG834 it didn't go very smoothly.

I'm not using wireless networking at the moment. AFAIK, my modem/router can't do WPA2 so at some point I'll probably get a modern "N" capable modem/router.

I knew it was too good to last:-

ADSL Link Downstream Upstream
Connection Speed 9122 kbps 1095 kbps
Line Attenuation 22 db 4 db
Noise Margin 6 db 7 db

Attenuation gone up to 22dB? Something very strange there. That could just about account for the speed drop.

Odd isn't it. I reckon about 19000kbps for that attenuation anyway

Yes, we've already covered the fact the speed at 16dB is pathetic.

I think the poster needs to try a different router.

The only other router I have to hand is an old Speedtouch 510. About 2002 vintage but flashed at least reasonably up to date. I don't think it can even do ADSL2+. I think a friend may have a Billion 5200 series modem/router (definitely ADSL2+ capable) spare so I'll try to borrow that.

It's worth a go .

Tried rebooting the modem/router and I've got my old speeds back again. Don't see how rebooting the modem can change the line attenuation.

ADSL Link Downstream Upstream
Connection Speed 12517 kbps 1104 kbps
Line Attenuation 16 db 4 db
Noise Margin 6 db 7 db

I'll try anther modem/router when I get hold of one.
