No gateway for WLAN

Hi,

I hope to be right here otherwise plz F'up2.

ok, I figured out how to configure my broadcom wlan device (Dell
truemobile within my Inspiron 5150 under Linux) with Ndiswrapper under
SuSE 9.2.

So for so good. The sole problem is that I can't get acces to the
internet. I presume it has something to do with a missing gateway.
Mysteriously it just appears when I use wlan. As soon as I plug into LAN
I will get a gateway. Until hotplug to LAN no gateway is listed by
"route -n".

Data transfer between two PCs ist esablished and working properly. Does
anyone has an idea were does this erroer come from?

Another problem is, that also I executed "ndiswrapper -m" at the end of
the Ndiswrapper installation/configuration the module is not loaded
automatically on restart. I've to load it manually on every start.

If I execute "ndiswrapper -m" I got the mesage: "modprobe config already
contains alias directive"
but it doesn't seem so. Which file to check for the correkt entry?

Sorry if these questions are annoying. plz be indulgent for a newbie.

thanks in advance

Can't you add it manually? If you can, then is not a problem of the
driver but a problem in your configuration.

tnx Davide for your answer. How do I add a Geteway manually. I just
tried to enter the gateway fix within the wlan config under yast2. But
there is no different in the route-output whether I do it or not. Is
there a command to do it from the command line (presume it is).

I'd no similar problem with my LAN-device. I'm starled cause
wlan-intranet works fine.

thanks in advance

TNX!!

But it seems to me I was wrong!

after adding the router or gateway-ip it doesn't change anything. I
still can't access the Internet.

see listing below.

What does this second ip for wlan0 mean (168.254.0.0) ?

Thanks to you for you patience. I hope you can help me to solve this.
I'm going crazy with this. And I thougth I'm going to leave the newbie
status:-(

TIA

Julian

169.254 is the so-called "zero administration network", is a
scam invented by Microsoft: if you have a machine that can't get an
IP trought DHCP an address in the 169.254 range is picked at random,
this allow (?) a machine to 'talk' to a network without configuration.
It seems that you have somewhere defined such thing.

It would be interesting to see which ip address you gave to the Wireless.
ifconfig wlan0 should show something usefull. My reading of this is that
your wireless is quite confused and doesn't know which ip to get.

So far as my knowledge allows: I'm quite sure the ip is ok. DHCP is
working much faster with wlan as it does with lan.

The router ip: 192.168.178.1

moskito:/home/modr # ifconfig wlan0

--------------------------------------------------------------------

I've no idea where to look any further. Sometimes i think it has
somthing to do with SuSE and/or me. I usually get probs often reportet
but can't be solved in the described manner.

But I still have hope an never give up!

Can you ping the router through the Wireless?
Does your Access Point have an IP? Can you ping it? Can you
see (through the Access Point's interface) your Wireless card
connected ?

This is quite strange, I've never saw 100/100 of quality...

Indeed, it seems that your link is Ok.

Yes I can. No percent package loss. A can also transfer data from an to
every pc pluged to the lan/wlan.

Doesn't it mean 100% (100 of 100). I'm quite close to the
AP/Router/Switch combo/device. I've got several WinXP (wlan and lan) pcs
in the intranet. Every computer can access the intranet as well as the
internet.

Any idea? Or do you know any other adress where to ask.

Yes, and I'v never saw such ratio, even if I'm 5 meters away from
the AP. Anyway, if you can ping the router and the AP, I'd say that
your card is functioning properly.

At this point you should be able to ping an address on the internet
and see a response, if you don't see a response I think that the problem
isn't in the card but maybe along the way.

Start with a ping to a well-known address (like www.microsoft.com),
you should get a) an IP address for the target and b) a response.
If you can't get an IP for the destination check the configuration of
your DNS. Also, check if you have a firewall that allows eth0 but
block wlan0.

tcpdump could also be used to see if you get an answer from the destination
machine at all or not.
