How long is it since you power-cycled your router? Preferably with a ten-minute interval between off and on?

SNR Margin (dB) 3.6 14.9
Attenuation (dB) 56.0 34.3
Attainable Rate (Kbps) 2736 708
Rate (Kbps) 1810 440
Router has been connected for nearly 2 days now (I changed the router 2 days ago)
What's the difference between rate and attainable rate?
Is there anything I can do to get my speeds back up to 2Mbps?

The low SNR Margin suggests either you are tweaking it or there could be a lot of variable noise. Did you change the router because of earlier problems, and are you tweaking?
I'm trying to find out what has been going on in the recent past and what problems you've had, as I'm surprised you could only download at 2Mbps some time in the past. The 56dB attenuation suggests much higher than that should be possible. As though you have a long-standing poor connection that has got worse.

Exchange: Kells BT Code: NIKS
I've tweaked the SNR (lowered by 2) in an attempt to get a higher sync speed. It doesn't seem to make any difference though. The line is currently stable though I've never really had a problem with stability - it's just the download speeds aren't what I'd like.

It didn't really make any difference. Prior to that I was connecting a splitter directly into the master socket
There is no extension wiring

Quote from: ejs The 440 upload, and 1810 not being an exact multiple of 32 suggests this is an ADSL2/2+ connection
Yes, that's why I said it was strange unless the IPStream product had changed. The stats in a later post are showing ADSL2, (not 2+?), and the exchange is WBC-enabled. I was confused by the 1.5Mbps IP Profile. I didn't check 88.2% of 1810, as my subconscious said it would be higher. But - 1,596.42.

Does it always re-sync at 1810kbps?
You say you used to get over 2Mbps. As I said before, I would expect a lot more. Have you ever had it in the 3-4Mbps range, and when did it start to degrade from over 2 to the current under 1.5?
Does anything on this page look relevant? I assume the router is not sitting on top of or very close to some other electrical/electronic equipment.

I'll try resyncing again later to check what speed I get - but I'm pretty sure it's always syncing around 1800 kbps
The fastest I've ever seen was around 2.2 Mbps. I'm not sure exactly when the speed dropped (I haven't been using it a lot) but it's been like this for a good few months
The router is sitting right beside the NTE along with a phone and a homeplug adapter

Those ADSL stats did show interleaving was at a fairly high depth, and there were quite a lot of corrected errors, which suggests there is some sort of noise or interference affecting your broadband.
