config wireless card


How, using the command line can I detect my wireless card and make it work under SUSE Enterprise Desktop? The wireless card works in Win XP.

Hello,

Look into the iwconfig command.
Code:
man iwconfig
It does what you need for wireless connections using the command line.

Kind regards,

Eric

lspci -v will list the name of the wireless card. This will help to check if the appropriate module is loaded at startup. You can check this with lsmod.

Hi,

Welcome to LQ!

You can check to see if the device is available with 'ifconfig -a' which shows the devices even if down.

As root you can use the below to configure a static IP with encryption for your wlan on your LAN;

Code:
~#ifconfig wlan0 192.168.0.18    #<<< available IP
~#route add default gw 192.168.0.1 #<<your gateway
~#iwlist wlan0 scan #<< use information to fill in for essid & ap information
~#iwconfig wlan0 essid "Your Wireless"
~#iwconfig wlan0 key your_key_here
~#iwconfig wlan0 ap xx:xx:xx:xx:xx:xx #<<Your _ap_from iwlist
You should have your '/etc/resolv.conf' setup with your 'ISP DNS' nameservers.

Code:
 sample '/etc/resolv.conf';

search 192.168.0.1     

nameserver xxx.xxx.xxx.xxx   #ISP DSN 'replace xxx.xxx.xxx.xxx
                             #with IP from your ISP
nameserver 4.2.2.1           #Verizon third level DNS
nameserver 4.2.2.2
nameserver 4.2.2.3
nameserver 4.2.2.4

Another way to setup static IP without encryption then do as root from cli;

Code:
~#ifconfig -a                      #get recognized devices
~#ifconfig wlan0 192.168.0.10      #set to a available IP
~#route add default gw 192.168.0.1 #set to your gateway
~#route -n                         #show the route table
~#ifconfig wlan0 up                #should be up already
~#ping 192.168.0.1                 #ping your gateway
~#ping 208.69.32.130               #google.com IP
~#ping google.com                  #test DNS, if fail then
                                   #check /etc/resolv.conf
This one assumes that your LAN/AP is setup properly for access.

BTW, make sure your '/etc/resolv.conf' has your nameservers for your 'ISP DNS'. I use the third level DNS as a fallback.

Paul, Gary,

Thanks so much for the info but it seems I'm a bit confused. I don't have an ip address, I log into free wifi at the cafe. How can I get iwconfig to show me the available networks and then connect to the one I select? I ran ifconfig and am attaching the result. Can either of you explain what the info means??? Thanks.

I don't see a 'wlan' device in the output you provided. What do you see in your 'lspic -vv' for the wireless device?

Gary,

I ran lspci -v and it comes up as a Broadcom wireless modem on IRQ 11. Now, I remember that when the boot up occurs, it sees the WLAN card and tries to recognize it and reports failed in the right column where everything else is 'passed'. So, I ran lsmod but I couldn't see any wireless module. I don't really know what a module is anyway. But maybe that's it. I need to load a module. Is that the same as 'drivers'? Any help much appreciated. By the way, I'm a US expat living in Australia now. From Kansas. Near you, eh?

Hi,

Post the outputs for 'dmesg |grep -i wlan' & wireless portion of 'lspci -vv'.
