Final wireless setup

andreltr · December 17, 2008, 1:24am

Hello,

I have tried every way I could and it was not possible to actually connect via wireless. I’m using ifup. Could anyone help please? The output is below,

Check the output from the ‘dmesg’ command. Any errors?

Hello,

Thanks for the prompt reply. The output is below,

andreltr@linux:~> dmesg | grep error
ahci: probe of 0000:00:1f.2 failed with error -22
Intel ICH: probe of 0000:00:1e.3 failed with error -5

Is your wireless device at buss address 0000.00.1e.3? If so, your device is
malfunctioning.

What I intended was for you to read the entire output of dmesg looking for
problems. Do not post it - just look it over for messages like “unable to load
firmware”, etc.

Hello,

I was able to connect via wireless (FINALLY…). However, if possible I’d have two more questions please,

1 - how can I configure the wireless card to work in several distinct places, e.g. home, work, pubs, etc.? Different essid I suppose…

2 - How the tasks used to connect via wireless, below, could be performed automatically during boot?

Thanks,

André Luiz

I forgot the show the tasks my apology. They were done as root.

linux:/etc # iwconfig wlan0 ap any essid “dlink”

essid show roam as my wish…

linux:/etc # ifconfig wlan0 up

linux:/etc # dhclient

Thanks again,

André Luiz

With YaST, change your network devices to be controlled by NetworkManager. After
you reboot, you will see a network applet in the right-hand corner of the screen

lower for KDE, upper for Gnome. Click on that and select “New Connection”.
Enter the data for your current connection. You can create one for each of your
locations.
