[NTLUG:Discuss] Wireless on a Sony VAIO

[steve]

I'm trying to get wireless networking up and working on
my son's new VAIO laptop.  Everything works using WinXP
and my LinkSys Wireless-G router using DHCP - but I get
"Network Unreachable" under Linux.

Here is the setup:

Sony VAIO PCG-782L - running SuSE 9.3.
Wireless chip: Intel PRO/Wireless 2200BG

SuSE auto-detected the wireless chip, I configured
all of the network stuff (I believe) correctly - but
a 'ping' to any of my other computers just comes back
with "Network Unreachable".

I can see the driver is installed ('lsmod' shows that
ipw2200 is installed and that 'firmware_class, ieee80211
and ieee80211_crypt depend on it).

When I open the device description in the SuSE
Hardware Tool (aka suseplugger) it says;

Status:
Available    Yes
Configured   No

...as far as I can tell, I *have* configured it using
YaST - but perhaps that's not what it's talking about.

Help!
