[CLUE-Tech] Wireless LAN question

[Francis X. Maier]

I'm running a D-Link wireless DWL-122 USB card on my Yellow Dog Linux 
3.0 (essentially, Red Hat for Macs)  iMac.

Per installation instructions, I compiled a new kernel, then installed
the linux-wlan-ng driver.  It works great; in fact, it works much better
than the card's commercially provided OSX driver.

One hitch though: every time I reboot, I have to reenter the IP
configuration again:

ifconfig wlan0 65.101.242.XX netmask 255.255.255.248
route add -net default gw 65.101.242.XX

I've been told I can edit the network configuration so that the card
comes on automatically when I reboot.

That means I need to edit one of the files in

/etc/sysconfig/network-scripts

But which of the files do I edit, and what exactly do I do??

Thanks for any help.
