Incredible find! thanks Axtim. I used the driver to install, and it worked immediately. Just to rehash the procedure in case someone stumble on this (btw I could not get the socketcom driver to work, like many people who are using the Symbol LA-4137 wifi cf card):
1. Uninstall any existing wifi driver using Setting->system->remove programs
2. Soft reset
3. download the .exe file from the link provided by Axtim, and extract the content into a folder
4. double click on setup.exe, and choose the first option (install mobile companion) over activesync
5. Whola, it's done. your axim copies the file, and mine prompted me for a soft-reset.
6. insert the LA-4137 card and everything detects automatically. The mobile companion has a tiny icon on the lower right hand screen that you can use to find wifi signal.
I haven't done any power testing, but the signal strength seems as strong as my PCMCIA netgear card (also a good card, for notebook).
thanks again.
