But no joy with getting it to actually send/receive anything over the
wireless network.

Any guru out there want to guide me into the light and get this thing
working? Much appreciate and thanks in advance...

Marc,

I'm no guru with Encore cards, but common problems with wireless are
often associated with encryption methods used (wep, wpa, wpa-2). Post the
output of iwconfig so we can look at the connection stats. If you want,
you can blank the encryption key info (no that it matters) like this:

16:48 alchemy:~/dev/prg/ccpp/lib/gsl> sudo iwconfig
<snip>

ath0 IEEE 802.11g ESSID:"skyline" Nickname:""

Also, have you ever had wireless working on 11.2? We will need to make
sure the driver is loaded. (we will know once we see the iwconfig info).
Check yast to see when it is being loaded ('on boot', 'on cable
connection', 'hotplug', etc..) I don't know whether encore uses
wpa_supplicant for encryption or not, but if it does, configuring
wpa_supplicant is separate from setting the card up in yast.

Somebody here will know what it takes to get the encore card going.

Thanks David for your reply. OK here is my iwconfig info and just for
completeness, my ifconfig info. I have had the wireless working on 11.2
with my laptops built in wireless card, but it failed so I have turned
it off and am trying to switch over to using a wireless USB dongle....
I have configured Yast to load it 'on boot' and am using WEP 128bit
encryption. I double checked the key to make sure it is right, and it
is.. In the interim I am using a wired cable for my laptop, but time is
running out as my wife is not a happy camper having a cable run across
our living room! ;-)

Marc..

don't know if 11.2 is ok w.it, but earlier suse versions had occasional issues
with network device numbers incremented almost arbitrarily
in /etc/udev/rules.d/(some number)persistent-network.rules or
persistent-net.rules. The fact that your wlandevice is called wlan2 might
confuse a script looking for a wlan0 / wlan1. you might want to manually edit
the .rules script by commenting out the line assigning wlan2 to your wireless
card and see where an "rcnetwork restart" (as root) or reboot (don't remember
well, tried this a while back) takes you.
