I have a problem with getting the wireless network up and running on my computer, like most of the posts in this group. In order to follow the excellent primer listed at the top of this subject, here are the facts:
The network card is a Linksys PCI adapter WMP54g. Running the “lspci” command gives the following information:
05:08.0 Ethernet controller: Intel Corporation
82801DB PRO/100 VM (LOM)
Ethernet Controller (rev 81)
05:0a.0 Network controller: RaLink RT2500
802.11g Cardbus/mini-PCI (rev 01)
Besides the wireless card, there is also an ordinary Ethernet connection, that works like a charm.
The “lspci -n” command reports this:
05:08.0 0200: 8086:103b (rev 81)
05:0a.0 0280: 1814:0201 (rev 01)
I had less luck finding a similar text line to the one listed in the primer when the “dmesg” command was used, but here is what wireless related I found:
ADDRCONF(NETDEV_UP): wlan0: link is not ready
wlan0: Initial auth_alg=0
wlan0: authenticate with AP 00:12:1e:b3:2b:02
wlan0: RX authentication from 00:12:1e:b3:2b:02 (alg=0 transaction=2 status=0)
wlan0: authenticated
wlan0: associate with AP 00:12:1e:b3:2b:02
wlan0: RX AssocResp from 00:12:1e:b3:2b:02 (capab=0x431 status=0 aid=4)
wlan0: associated
wlan0: switched to short barker preamble (BSSID=00:12:1e:b3:2b:02)
Then, on to the “iwconfig” command, which indicates (for ESSID: “DJO345” which is the one I’m trying to use) :

And finally (I am aware that it is a lot of information listed), when I run the “ifconfig” command I get the following information:
eth0 Link encap:Ethernet HWaddr 00:08:02:86:AC:45

I enclosed the information about the Ethernet link as well.
Anyway, to me it looks like my wireless card is up and running, I have an IP address, I have contact with the Access Point and so on… but it simply doesn’t work.
Now I aware that there is other network specifications that you specify, via YaST for instance. I have tried to i) use the default to start with, and ii) made sure that the network specification is the same as for the Ethernet. Still no luck.
You might argue that the error could be outside my Linux computer, the home firewall or something like that for instance. True, but I have dual boot on this computer and when I start up Windows instead, I get the same IP-address, for the same card and everything works fine.
Any suggestions would be very appreciated.
