wlan config problem

Dell Inspiron 9100 with a 1450 wireless card (broadcom chip). Configured the
card successfully with ndiswrapper under shrike. I can ping my win and linux
servers on the lan, but no internet. Fruitless efforts at DNS, and here I
am. Where is the magic config setting that I'm missing? Thanks in advance .

A bunch of stuff I've tried (sorry for the length, but you'd probably ask
for this output anyway):

?? 169.254.x.x ? This is usually done in Windows when a nic can't get
a correct ip address. Check better.

192.168.1.0 means 'your local network'. It's the 169.254 that shouldn't be
there at all.

?? What's this ? You didn't get the DNS correctly from the dhcp
server or you didn't configured it.

Thanks for the reply.

I'm using static IP's. I'm obviously not a linux networking expert, I just
want this darn card to access the net. Can anyone point me to how to
properly configure the DNS for this to work

I've tried setting the Gateway to my router's WAN address, as suggested in
an online article, but didn't work.

And, yes, how is a card in a linux machine getting a Windows default IP like
169.254.x.x? Is this due to ndiswrapper using the win driver?

Then the '169' thingy should _not_ be there. At all.

Basically the /etc/resolv.conf should contains:

nameserver <theipofyourprimarydnshere>
nameserver <theipofyourotherdnshere>
nameserver <theipofyourotherdnshere>
....

At least ONE 'nameserver' entry must be there.

You need to set the gateway to the IP of the machine/router that
give you connection outside in your LOCAL network. The meaning of
'gateway' is "all the packets that you don't know where to send,
send them to this IP". Of course he has to _know_ how to send to the
gateway _first_. So you need at least two entries in the routing table:
one for your local network (and you have that one) and one for the
gateway (that is usually in your local network).

Could be. I've never used ndiswrapper in my life so don't ask me...

Looking at your ifconfig output, you are not actually getting an
IP address - you are only getting a route to that network.

It's a "feature" that Red Hat decided you couldn't live without,
If you look in /etc/sysconfig/network-scripts/ifup you'll find:

# Add Zeroconf route.
if [ -z "${NOZEROCONF}" -a "${ISALIAS}" = "no" ]; then
ip route replace 169.254.0.0/16 dev ${REALDEVICE}
fi

So if you set NOZEROCONF=yes in the /etc/sysconfig/network configuration
file, this "feature" will be disabled. This "feature" is called Zero-conf
or link-local, so you might look through the documentation for those words,
and see if RH says anything. It would not surprise me if they didn't.

Old guy

thanks for solving the 169 IP mystery. it's working now, except for a few
minor details (like why it's still listing the 169 IP).

kudos to the ndiswrapper group for letting us use new wireless devices until
linux drivers are available.
