Unable to obtain IP address using ndiswrapper

Hello,

I'm trying to connect my Dell laptop to my access point (Linksys
WRT54G) using ndiswrapper. However, after I install and configure
ndiswrapper, I'm unable to obtain an IP address from the Access Point.


Background
Dell 1150 Inspiron
Wireless network Adapter: Dell wireless 1350 mini-PCI (this is a
broadcom chip, the driver I downloaded off of
ndiswrapper.sourceforge.net list).
OS: Fedora Core 3
network devices on machine: wlan0 (the device I'm trying to connect
with), eth0 (this is a built in ethernet controller, lo, sit0 (I'm not
sure what this is)

Access Point - Linksys Wrt54g
essid = star
channel = 11 - 2.462 GHz
mode = managed
wep = enabled
key = '555555555'

www.linuxant.com that increases the stack size )

When I issue the command /sbin/ifup wlan0 the message I receive:
Determining the IP information ... failed

Question:
1) I am able to set my ESSID to "star" on wlan0 (from the output I did
associate with the access point correctly). However, I suspect it's
the ifcfg-wlan0 file that is missing/incorrect settings. Does anyone
have a ifcfg-wlan0 sample file or know where to get more information
about the settings in this file?

2) Once the ifcfg-wlan0 file has been corrected, how do I bring this
network device online? /sbin/ifup wlan0? How do I automatically
bring it online everything the laptop boots up?

3) This is a little off topic, but once I configure the laptop
connectivity with the AP, does the AP always need to have its ESSID in
broadcast mode in order to connect using ndiswrapper? Previously, the
laptop was running XP, and I was able to connect without using
broadcast mode.

Thanks in advance.

have you tried configuring it by hand with:

dhcpcd -d wlan0

I don't have dhcpcd. I couldn't find it with "locate dhcpcd" I'm
using fedora core 3.

How does I set the security mode to open in the ifcfg-wlan0 to the
setting SECURITY_MODE=open?

Where can I get more information about what the setting names and
allowable values are in the ifcfg-XXX file?

Thanks

Well, I guess you should load it then. Get the rpm and install it. Of
course you may have one of the other dhcp clients.

??

The only way I have found is to read the script that uses that config file,
probably something like ifup or ifup-wireless which will be in
/etc/sysconfig/network-scripts
That will also show you which dhcp clients it tries (on mandrake they try
dhclient, dhcpcd,pump, dhcpxd in that order. -- see the ifup script)

Note that it is the router (wireless access point) that determines the
security, not your system. I cannot find any reference to SECUR in the
scripts.

Not sure if you ever got this resolved, but I JUST got this fixed on
my Dell Inspiron 5100 with Truemobile 1300 after about 5months of
work and research. It's so simple it's insane. If you're using
Gnome, go to the Network control panel. Click on the wlan0 interface
and click Edit. Check the box next to whatever says "IPv6", click ok,
save and then reboot. That's it.

I really hope that this helps as I was absolutely stunned when that's
all I ended up needing to fix it for me.

BTW - I'm now using Fedora Core 4 with ndiswrapper 1.2
