ADSL line performance

Could somebody advise me about the following line stats. It seems to me that
they are quite poor but I might not be understanding what's happening.

I'm beginning to suffer from reduced sync rate during peak times which is why
I'm looking. I'm using a D-Link DSL-300T modem on DSL-MAX servvice. It reports
the following:

Modem Status
Connection Status Connected
Upstream Rate (Kbps) 448
Downstream Rate (Kbps) 7360
US Margin 20
DS Margin 7
Modulation GDMT
LOS Errors 0
DS Line Attenuation 26
US Line Attenuation 22
Path Mode Interleaved

What's troubling me is the DS atten of 26dB but a DS margin of only 7dB. I
think margin is equivalent to SNR (?) which suggests there's a lot of noise
coming from somewhere.

I've seen it suggested that performance like this might be due to house wiring
problems. Is this likely? What should I be looking for?

Any guidance appreciated.

If you are on a MAX package don't sweat it as the standard default threshold
is 6dB for your DS margin. Start getting worried if your service (if older
than 2 weeks) is unstable, drops out or just stalls then you will need to
get in touch with your ISP.

Many of us here would kill for 7360Kb/s !
Don't worry, be happy...

Depending on his ISP he may only actually be getting 10kbps sometimes.
