I just got an wcf12 from ebay and I was trying to connect my sl-5500 + wcf12 wit my mac + Airport extreme.
I created a network on my mac just as I would do wit any other machine. Then I tried to set up my zaurus to connect with this ad-hoc network with any succees. I can succesfully connect wit other non wep ap with my zaurs.
The setings I'm using are
On my mac:
Channel 1 and no wep (the name has no spaces)
On my zaurus:
config: I unchecked the non-spec ESS-ID and entered my netwok name. I changed the network type to 802.11 Ad-Hoc and set the channel to 1.
(no wep, no tcp/ip options)
The card blimps couple of times and does not connect.
On the other hand I tried to connect to a 128 wep ap without any succes either.
Oh by the way i'm using sharp rom 3.1
