I had Windows XP. Recently I installed openSUSE Linux on my other drive. I had access to the internet through a wireless connection in Windows XP. For openSUSE I wanted to configure my wireless network too.
I went to YaST, and scanned the network. It finds my ESSID successfully. In Windows XP, I would enter my password, but there are no options like passphrase/ASCII/decimal for encryption. Also, the device type is grayed out.
If I'm wrong and the password of my network card shouldn't be entered there, then what should I do?
When I type ifconfig in terminal, I get eth0 and eth1.

the output for iwconfig
lo no wireless extensions.
