The line stats you are providing from your D-Link router are very limited and as such make it difficult to offer a very definitive opinion on your line condition, have a look at the "DSLStats" web site and you can see the sort of detail that is available from a suitable router, not sure if your particular D-Link router falls into that catagory, basically has to use a Broadcom chip set and have Telnet/BusyBox access.
From the limited stats provided, the best estimation of line length is from DS line attenuation (shown as DownLink on your router) yours is 26.9 dB, that's a long line (house to PCP/fibre cabinet) by VDSL-2 standards, measuring physical distance to the cabinet can be misleading as the cable very often does not take a direct route.
As a close comparison, my line shows a 29.8 dB. DS attenuation and I get very close to 40 Mbps. DS synch and approx. 5.6 Mbps. US synch speeds, so in theory, your line could do better but accepting that every line is unique and every modem/router can behave well or badly on different lines.
Your DS SNRM shows 5.9 dB which would normally indicate that a greater DS synch speed could be achieved but would really need to know if your fibre cabinet was Huawei or ECI and if DS G.Inp was active.
I also see my uptime is showing 9 hrs. Why is that I changed to this dlink router on Sunday and have not changed or switched it off
Your stats show the "DSL up-time", it's very likely you had a DLM re-synch for some reason, this usually occurs in the early hours of the morning, approx. 01:00 to 04:00 hrs. but can be any time, more detailed router stats would show "router up time" as well so you could tell the difference between a DLM re-synch and a re-boot of the router.
Try to establish if your D-Link router supports more detailed stats provision, there's plenty of good information available on the subject on this forum and on the "Broadband" information section, with more detailed stats there will be a much better chance of diagnosing if your line is performing to it's best capability or you do indeed have an issue.
