Hi,

I had ethernet (eth0) and wireless (wlan0) working well before I run an=20
emerge world (which updated baselayout)
At that time I also had eth1, which I don't know why, and the normal lo.
After the emerge, my wlan0 was gone. I still have the init script (not sure=
=20
if is a new one, or was overwritten), that gives the following errors:

# /etc/init.d/net.wlan0 start
SIOCSIFADDR: No such device
wlan0: unknown interface: No such device
SIOCSIFBRDADDR: No such device
wlan0: unknown interface: No such device
SIOCSIFNETMASK: No such device=20

The ifconfig command presents this:

Now I have a new sit0... again, no idea why!!=20
So what I would need is to know how to get back wlan0 and get rid of eth1=
=20
and wlan0.=20

Sorry for presenting so simple problem...=20
thanks in advance
Fernando.
