A comment from a dupe that matches what the upstream bug says and might be helpful info:
gnome-nettool reports my "Link speed" as "not available", unless I run gnome-nettool as root, yet gnome-nettool has no way I can run it as root via a desktop file. The gnome-nettool package should include a gnome-nettool-as-root.desktop -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-nettool in Ubuntu. https://bugs.launchpad.net/bugs/44299 Title: Link speed: not available Status in GNOME Nettool: Confirmed Status in “gnome-nettool” package in Ubuntu: Triaged Bug description: Hi, This seems like a bug to me. gnome-nettool claims it cannot give me the link speed. but mii-tool does this just fine.
