IMPORTANT NOTE: This page is deprecated, updated documentation can be found here

IMPORTANT injection with wlan-ng is only supported in kernels less then or equal to 2.6.11.

Important note: when the card is inserted, wlan-ng will flash the firmware in RAM (volatile download) with versions PRI 1.1.4 and STA 1.8.3.

Many users experienced problems with this operation, so in any case it's safer to just use hostap instead. Furthermore, HostAP works more reliably and supports iwconfig whereas wlan-ng doesn't.

If your card appears to hang (no packets captured or injected), disable the interface, reload the drivers and re-insert the card. Also consider updating the firmware (if Prism2).
