Every 750k or so the downloads either stops for 2-3 seconds or the
download actually fails. Something about the connection being reset
(depending on the program I use for the download).

Mmmh, as far as I remember the kernel was not updated.

I am using a different connection now (different house). The download
does not fail, but there is still a form of slowdown / short stop every
700k - 800k. I also trried the tcp_window_scaling thing, not too much of
a difference, I am afraid.
There is still pattern being repeated in wireshark, even though it seems
to be not quite every 700k - 800k, but at more random intervalls.
