I did something similar this morning to a Dell laptop. Set up
ndiswrapper per the INSTALL and readme files in the tarball.
Make sure ndiswrapper -l indicates that the device is installed
correctly. dmesg will indicate whether ndiswrapper found the hardware.
If this all goes well, then add:
alias wlan0 ndiswrapper
to modprobe.conf.
In the /etc/sysconfig/network-scripts directory create a file called
ifcfg-wlan0 with something like the following:
# Broadcom Corporation|Wireless thru ndiswrapper
DEVICE=wlan0
BOOTPROTO=dhcp
ESSID=your-ESSID
KEY=your-WEP-Key
RATE=auto
ONBOOT=yes
TYPE=Wireless
Substitute in your ESSID and WEP key. After that "service network
restart" (or reboot) should restart the network interfaces. You will
probably need to "modprobe ndiswrapper" if you do not reboot.
In my setup I wanted the I/F to start on boot, you may say "no" if you
don't. Also the card in my laptop is a mini-PCI and is always
installed, relieving me from the hotplug issues. You did not say
whether you were leaving the device constantly plugged in. If not, you
might have to play with the hotplug configuration to get ndiswrapper
running at the correct place in the system startup.
BTW: ifconfig -a will show all of the network interfaces the box thinks
are available, and iwconfig will show the wireless interfaces it finds.
