Your connection speeds ('bandwidth' in your stats) look a bit odd, and much lower than should be achievable on your line with its fairly low attenuation. I suggest that you switch off the router, give it a few seconds, then switch it on again to see if it comes up with a better speed. You'll have to monitor your stats regularly to see if they change by a large amount at any time, for example when making or answering telephone calls, or when switching electrical appliances on or off. There seems to be something badly wrong, but it there are lots of possible reasons.
