When you select ¨Under 'IPv4 settings' one can choose among 5 methods:
automatic (DHCP)/automatic (DHCP) addresses only/manual/link-local
only/shared to other computers.¨ manual and fill in the information,
the button becomes usable. You need to click add, put in the IP
address, etc, click in the empty space of the box, then click OK or ADD
next to it. Then add the dns server address. Then OK at the bottom will
be usable.
