Albert...understood completely.. We have Charter here delivering 60MB on download which surprisingly measures higher than that using speedtest.net repeatedly even during peak periods. The one thing I ran into with the Samsung UHD4K panel 3 months into owning it was a quirky WiFi receiver module that had to be replaced as it was one of the first units to hit the market and i purchased it as soon as it came out; once I did that, I had hiccup-free Netflix, VUDU, etc....coming in at UHD and HD according to its source.
Similarly good results for Oppo 105D (own one as well) for Netflix and other apps which has proven stable and reliable on the Charter link. The only caveat on reaping all that was coming in viz. bandwidth from Charter was that with a WiFi router, there are very few that truly pass on all the bandwidth from the Cable or DSL model they are tethered to...9 of 10 prior routers I've owned (Netgear, Linksys, etc..) were dependable but even for the prior 802.11 a/b/g/n capable ones, they would wind up limiting what devices connected could actually achieve in terms of speedtest/other measurements for sustained as well as burst mode receives. The Netgear X6 I wrote about above is the first that lets me have the full bandwidth of the incoming cable line actually passed on to any WiFi-connected device. Expect the X7 router from Netgear capable of the same.
As far as DSL services, I have avoided them, as a matter of preference and capability. Here's two interesting links on DSL types;
