Those stats indicate there is possibly a wiring problem at your end. Also I wonder if the last time you sync'ed was in the evening while there was a thunderstorm in the area.
The downstream rate for an attenuation of 49dB should be much higher than 1536kbps. Part of the immediate cause looks like the very high SNR, (which is actually the SNRM - a different thing altogether). If your last sync was as I suggest then the 15dB could be fine. If your last sync was on a nice sunny day then it is bad.
Depends how much effort you want to put in

. I used to use a WAG54GS and it gave me an attenuation of 52dB. My normal sync was 6464kbps. But I have an exceptional good clean line and wiring. You are unlikely to get anywhere near that, but we should be able to improve things a lot. Possibly 4000-5000kbps.
Also, the wireless bit on my Linksys went duff, so I got a refurbished SpeedTouch 585v6 from DSL Depot for �23.98 inc postage. Straight out of the box it showed attenuation 49dB and sync'ed at 7008kbps. They are out of stock at the moment I think but somebody was thinking of buying from eBay for �25.
But! Leave that sort of thinking till later as that's a minor improvement compared to what we hope to achieve.
Have a look
here and do what it says re the ring/bell wire in the master socket, and any extensions if you feel like it though some people say those don't matter.
Ideally, in broad daylight if possible, can you connect to the test socket inside the master socket, and get the stats immediately it has sync'ed? With luck the SNRM will be lower and the sync much higher. The actual download speed will not change though. You may find that the sync at your normal connection point improves anyway after removing the ring wire.
Is absolutely everything in your place that connects to the phone line going through a filter? Sky box, burglar alarm, every phone, anything.
That's all for now as it will give us a much better idea of where the problem may be.
