Telekom, cable. My upload has always been crappy.
I download with 33mb/s but upload like a snail.
But that will change for the next release, as I'm moving next month and then get 1GB/s.
Me Telekom too, but WiFi. We have an ok download speed, just medium range, we do not really need more, but restart of the router can link you into a better (or worse if you do it at the wrong time) speed line. But it is interesting that you have such a slow upload speed. As said, I am rather sure that our net is slower than yours, but the few times I have to upload stuff, e.g. to some Ämter, it is not as slow as your upload speed.
But then again, soon your net will make ZZZOOOOOOMMMM!
