Eran Hello, I've followed the advice on your page for flashing the prism2 firmware. It worked for me once before, with an Ambicom WC1100C-CF card. After I got another two, I tried following the same procedure, but it failed for both of them. I've got errors such as: Could not read wlan PDA. This requires PRISM2_DOWNLOAD_SUPPORT definition in driver/module/hostap_config.h Even though I had it compiled. Further digging and debugging found out that while the hostap driver had wlan0 as the device name, udev took "good care" of me and moved the newly added cards to wlan1, wlan2 (unique device name per card). That was why flashing failed for both device names I've tried. Removing the local rules file of udev for network devices solved the problem. I've found your page useful - I hope my story will be of benefit to other visitors. Eran
