802.11g And Wpa?, supported at all on any ROM any version? Options

[speculatrix]

has anyone gotten an 802.11g card to work, and with WPA?

snag is at work they only want to run 11g and WPA (Apple airport extreme) on their wireless lan for security; there's only a vague chance they would drop it down to 802.11b (if the Senior Sysadmin decides to get an iPaq with wlan)... but will definitely stick with WPA.

I would get murdered if I put up my own access point (and rightly so!), so I'd have to use bluetooth, which is OK for surfing but not for file transfer.

I would be happy to choose ANY rom, and I have quite a lot of experience with linux and 802.11~ from hacking together an access point with the Keith Smith OpenSTA/OpenAP stuff on a eumitcom single board computer, so am not afraid of getting my hands dirty!

thanks for any thoughts
Paul

I spent the weekend trying to build the Agere Systems driver for the Zaurus and get it to work. I managed to build it (after making mods to the code and the config), but I don't think it will work in it's current form. The 7.22 version is the only published one with support for the 54g card.

The driver is recognised and loaded when the card is inserted, and you can see the debug logging from the driver if you run dmesg. I added some logging of my own too. The driver goes bang after dereferencing a null pointer in hcf_connect. The driver comes in two halves - one half passes a 'device address' to the other half. The top half of the driver gets a 32 bit value for the address. The bottom half is assuming a 16 bit value and it comes through as zero - later going bang. The release notes for the driver say that they haven't finished 32-bit DMA support yet and it only works using 16-bit port I/O. I think this is where the problem lies. Anyone with deeper knowledge of drivers feel free to mail me for details or have a go yourself!
