A friend is complaining of slow broadband speeds. Okay it's ADSL 2+, but we've seen speeds of maybe 15 in the past. He says he's getting maybe 3 Mbps on average at the moment.
Have just been looking in his modem/router. The attenuation reports 180 downstream.
Here's links to the statistics from the router :
So, downstream rate is 6656 but the attainable rate is 13584 (Kbps).
Downstream attenuation says it's 180, and SNR margin 146.
Is that just an unusual way of expressing attenuation and SNR margin, or do we have a serious problem here ?
I've run Fault Diagnostics tests on the line, KBD tool Non-intrusive and intrusive. Nothing of interest there - result "No issues have been identified in the BTW network. KBD test indicates no BTW network fault. Please perform all CP and End User checks. BTW Performance/Speed test has not been run."
My next step will be a visit to check things like internal wiring, dongles, etc.
But does anyone with experience have any recommendations ?
Oh, and at the ISP end, it's reporting multiple disconnections most days.
