Wireless card

**ciscocbee** · 06-19-2005

I am obviously completly new to linux.
I have installed slackware 10.1 and upgraded the kernel to 2.6.11.6.
I have a centrino system with an intel 2200bg wireless card. I installed both the firmware and the drivers. When I run iwconfig I get this:

root@Pete:~# iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

eth1 IEEE 802.11b ESSID:"Tius1" Nickname:"Pete"
Mode:Managed Channel:11 Access Point: 00:0F:B5:54:65

dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

And from KDE I get pretty much the same information (from KWiFi Manager). It is talking to my wireless router, but I cannot get any web pages to come up (page not found error) and if I try to ping my router (or another computer) I get a "network unavailable" message from the console. This is a dual-boot machine running windows 2000 and the wireless works fine in there. I have a vauge suspicion that I'm missing something pretty basic. Any help would be greatly appreicated. Thanks.

What does ifconfig tell you? Try also

Code:

ifconfig wlan0 up

and then try ifconfig again.

**ciscocbee** · 06-19-2005

OK ifconfig wlan0 up gave me a "no such device" error. Anyway, here is the ifconfig data. I also ran iwconfig again since I'm at home on a different network. Not sure that it matters.

Ok, eth1 is your wireless device. Try setting the settings again (iwconfig), I have to run it whenever I want to connect to a network. At home, the only thing I have to set is the ssid, everything else I leave on auto. The settings are probably the only thing which need to be tweaked, as the wifimanager is seeing the network. Then just run dhclient (or dhcpcd) and you should be set to go.

**ciscocbee** · 06-20-2005

When you tell me to run iwconfig to set the settings, do i just type that in or is there additional information I need to give? I looked at the man page, but I'm not sure what to change. It recognizes my router SSID after all. Anyway, after running dhclient I got a "No broadcast interfaces found" error:

root@Pete:~# iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

So I looked at the dhclient.conf file and it is empty (see below):

Contents of dhclient.conf

# dhclient.conf
#
# Configuration file for ISC dhclient (see 'man dhclient.conf')
#

Do I need to put anything in this file? Should dhclient automatically fill this in? I checked the man page for this but I'm not sure what to do, if anything.

You also have to set the device to use DHCP by adding a "yes" to the "USE_DHCP[#]=" variable. Make sure your /etc/rc.d/rc.inet1.conf shows this:

Code:

# Config information for eth1&#58;
IPADDR&#91;1&#93;=""
NETMASK&#91;1&#93;=""
USE_DHCP&#91;1&#93;="yes"
DHCP_HOSTNAME&#91;1&#93;=""

I have to set the ssid, before I do I can see the network (SMC) in the Kwifimanager, after I set it doesn't show the network anymore (I think Kwifimanager is supposed to show only the available networks, not networks which you are connected to). I'm not sure how exactly to set the ssid, I set it with a graphical program I have in Kanotix. There might be some config file or something to set it, possibly an argument when you run the 'iwconfig'. Maybe someone else here is more familiar with iwconfig? You could also try googling it up.

OK, so I went into /etc/rc.d/rc.inet1.conf and changed the DHCP to "yes" and rebooted, and my internet works! (In fact I'm replying via slack as we speak). Thank you to everyone who helped.
