Also, if moved to a DHCP part of the interface, calling the button "renew" isenough to get what it does.Still, it shouldn't be there: it's something you will hardly ever need in your whole life. I only used the "Repair" button in Windows so far, but it *never* worked for me anyway. I never had to use any such thing in any other OS; so far it always just worked. Furthermore, the button has no meaning for static interfaces. Just to repeat: it make no sense to have it there.
If you don't knowhow to label a button, it's likely in the wrong place.Once the button is reachable in the proper place, I'm not against a popup menu for quick access by powerusers, should they ever need it.
