Alex,
I was not doing any finger pointing. Your system is everything - hardware,
kernel, and user-space routines. Obviously something is not working.
I have a Rosewill RNX-N180UBE. The chip is a RTL8191RU, but appears to be
programmed the same as the RTL8191SU. Mine works with the standard r8712u driver.
The two possible firmware files have the following md5sum:
200fd952db3cc9259b1fd05e3e51966f /lib/firmware/rtlwifi/rtl8712u.bin_122328
8e6396b5844a3e279ae8679555dec3f0 /lib/firmware/rtlwifi/rtl8712u.bin_129304
Could you please download a Live KDE CD from
http://software.opensuse.org/121/en? It should not matter whether you use the
32- or 64-bit version. After you boot it, use the NetworkManager system tray
applet to connect to your system. Does that work?
Next, use 'ps ax' to get the PID for NetworkManager and kill it. Then try your
iwconfig/ifconfig command sequence. Does that work?
Both sets of connection methods work here. I used the 64-bit system with my
Rosewill device.
Larry
