dabs rock! ParcelForce delivered the goods within 17 hours of my order. Some other online retailers never manage such a quick turn around.
Setting up the WG602 access point was a piece of cake. I already have a DHCP server (and BIND) on my main machine at home (tom) so I just added the MAC address to the DHCP server and, hey presto, web access to the router. All totally configurable from Mozilla. Excellent - it took under 20 minutes to secure the AP.
The PC card (WG511) installed seamlessly under Windows 2000 Server on my laptop (sylvester) and again once I (finally) overwrote that with Windows XP Pro.
Under Linux (Fedora 0.95) lspci recognises it as a D-Link DWL-g650 (which has the same chipset). In fact a quick google shows that these dudes have drivers and firmware for this card. Let's see if it works.
