Hi,
I’m a windows user for a long time but with the arrival of the New Year I decide it was time to learn Linux and install OpenSuse 11.3. At the beginning I didn’t have any problems with my wireless USB. But when I had to change my old router (due to change of ISP) the problems begun. At the time I decide to use a new encryption method (WPA/PSK) instead of the old one (WEP).
I did the setup with YAST but I didn’t succeed at first. But like everyone I start looking for what might be wrong, and tried to change this and that expecting to fix my problems. Finally, I give up and ask for your help.
My wireless card doesn’t get an IP address from the router (DHCP server). Why ? Did I mess something ? maybe, maybe it’s time to upgrade to opensuse 11.4.
Output of the lsusb command

I guess my wireless card (Linksys WUSB54G Wireless Adapter) is known to the system.
The same conclusion I think can be obtained from the output of the dmesg|less command.

Next step is the wireless card associated ? let’s first look at the dmesg|tail

It’s seems so. but what’s the output of iwconfig command

Now what about IP address

No IP address ? That means I can’t ping to other computers in my LAN or to interner. Might be no dhcp process running ?

Well. it’s running. Let’s check the route table
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
loopback * 255.0.0.0 U 0 0 0 lo
Just one entry in the route table ? that’s strange ?
Now that 's the end of the story and no idea of what might be causing the problem. So I ask you if can give any hints or directions that I can follow in order to to fix my first linux problem of not having wireless card working. Many Thanks.
