I'm hoping that someone can help me configure the wifi in my laptop.
I started with ArchLinux and I was able to get the wifi working
without too much difficulty. I was able to determine that the
interface was wlp3s0 and using wpa_supplicant and dhcpcd I was able
to get connected to both my home and work wifi.
Not being smart enough to leave well enough alone I decided to try my
hand at LFS and I've had nothing but trouble with the wifi. First
step is to issue the command "ip link set wlp3s0 up", at least it was
on arch. When I use the same command on lfs I'm getting "Cannot find
device 'wlp3s0'"
The "iwconfig" command shows 3 entries, lo, enp134s0 and sit0. So I
try "ip link set enp134s0 up" and I get errors:
sky2 0000:86:00.0 enp134s0: enabling interface IPv6:
ADDRCONF(NETDEV_UP): enp134s0: link is not ready
I guess my question is, why is my interface different now and what
should I do to find out what device I should use?
I think getting wifi up is one of the more difficult tasks we have.
I suspect you don't have the right driver for wifi. Just guessing, but
I also think enp134s0 is the wired interface (don't you love udev). We
can change that to eth0 if you want.
You should have an entry in /sys/class/net for wifi0 or wlan0 for the
wireless. Some cards also require firmware. What does lspci|grep -i
net give?
You can also try a commercial distro like mint or ubuntu and see what
their configuration shows you.
