You know, I saw that in the 10.x days, but usually with ethX interfaces. Now
that you mention it, wlan2 does sound like that may be a problem. (it's usually
wlan0) IIRC Marc, has the built in wireless + another one. That would account
for wlan0 and wlan1 -- but why wlan2?

Marc,

        I should have suggested this earlier, but (1) open yast and delete ALL 
of your
wireless connections, (2) go open the udev rules file (on 11.0 it's:)

16:36 alchemy:/etc/udev/rules.d> cat 70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program run by the persistent-net-generator.rules rules file.
#
# You can modify it,as long as you keep each rule on a single line.
# PCI device 0x10ec:0x8136 (r8169)

(3) make a backup of the file (always a good idea)

(4) delete all the wireless entries

(5) go back to yast and re-add your wireless card

(6) rcnetwork restart (or I'd just reboot to make sure any lingering code from
prior drivers doesn't remain resident in memory)

(7) then go back to working on the connection, scan test, etc..

Thanks d.
