Unfortunately I can't run those tests for some reason, probably because my modem is in bridge mode which means that everything is passed directly to my FrtizBox 7581, formerly from XS4ALL as a modem and now serving as a router.

Since a few months I now have 1gb/75mb regarding the upload which is often closer to 80mb and the download 975mb.

All cabling and UTP switching are at least 1GB.
Wireless are only my Samsung smartphones
Nearly I forgot the HP Smart Tank Plus 570 printer
