[gentoo-user] A simple explanation on how to get wireless working on my laptop ...

[Richard Watson]

Hi - Can anyone explain to a complete idiot (me) simply how to get my
internal wireless adaptor going. I know it works as I've got it running off
the Livecd and XP on an unsecured network. I went through creating:

# ln -s net.lo net.eth0 (Wirelesss card - reports wireless extensions not
found)
# ln -s net.lo net.eth1 (Seen as NIC and gets IP from DHCP server)
# rc-update add net.eth0 default
# rc-update add net.eth1 default
Everything in /etc/conf.d/net is set for dhcpcd
So far I've emerged wireless-tools and ndiswrapper but I think I'm missing
something fundamental ...

# iwconfig eth1 says wireless extensions not found

Any help would be really appreciated.

Thanks, Richard

what is the output of 

# lspci 

you may need to 

# emerge sys-apps/pciutils

to get lspci.

This is the device you need to get working, make sure /usr/src/linux
points to your current kernel version and try this:

# emerge -av ipw2100 ipw2100-firmware

If that goes well, then do this:

# modprobe ipw2100

# iwconfig 

You should now have a device name.

# iwconfig <dev> essid any

# ifconfig <dev> up

# dhcpcd <dev>

# ping gentoo.org

hth,

OK ... You're a genius thanks ...!!! The following worked ...

# emerge -s 2100 returned net-wireless/ipw2100 and
net-wireless/ipw2100-firmware
# emerge -av ipw2100 ipw2100-firmware

I rebooted .. then after turning encryption back on and then:

# iwconfig returned new interface eth2
# iwconfig essid XXXXXX
# iwconfig key XXXXX
# dhcpcd eth2

Everything works ...!!!! So ... how do I enter this into /etc/conf.d/net so
it happens automatically at boot.

My net only contains :
iface_eth0="dhcp

The "real" config is in /etc/conf.d/wireless
you should have a wireless.example file there to help you out.
