Hi all,

On 11.1 I had no problems. On 11.2, after seeing errors in /var/log/
messages showing "ifup: No configuration found for wlan0", "wlan0:
link is not ready" etc, somehow just enabling dhcp on eth0 via yast
allows this alias to work:

alias wan2='rcnetwork stop && ip link set wlan0 up && iwconfig wlan0
essid ZyXEL && dhcpcd wlan0 '

The problem now is that while I have a wireless connection via setting
the essid manually, I need a kinternet or network manager type of way
to get a connection - for the type of places that don't know their
essid. hwinfo shows:

I think the right module is installed:

However, yast "network settings" doesn't show any wireless cards. When
I try to add --> device type wireless, I check "usb" since hwinfo
shows "rt73usb" , I get:

wlanbus (No hwinfo)

Device Name: wlanbus-usb
Started automatically at boot
IP address assigned using DHCP

Therefore I see no option in kinternet to add a connection to wlan0.
If there is no UI way, knowing how to get the available essid's would
help - "iwlist wlan0 scanning" doesn't work if the network is down,
only works if I already have a wlan0 connection. Please help.
