I'm trying to install Gentoo from the LiveCD (just for fun as well as for getting better understanding what's going on under the Linux's hood) on my notebook. I've faced an issue which is not described in manuals quite well. When I'm trying to ping anything:
livecd~# ping 18.104.22.168
I'm getting this:
connect: Network is unreachable
There are three interfaces presented: lo, enp30s0 and wlp4s0. None of them has IP assigned. As the notebook should connect to the network using wi-fi, I suppose the default interface is wlp4s0. I'm trying to bring it up:
livecd~# ip link set wlp4s0 up
but with no luck, it still has state DOWN.
Anyway, other devices (notebook, phone, tablet) have perfect wifi connection.
