===== rndis_wlan =====

The **rndis_wlan** [[en/developers/Documentation/Glossary|FullMAC]] driver was added to the stock kernel as of 2.6.25. It is also available through [[en/users/Download|the compat-wireless-2.6 package]] for pre-2.6.25 kernels. 

 


===== supported chips =====

Broadcom 4320 USB WLAN chip, which is only wireless RNDIS chip known to date. Althought rndis_wlan has vendor/device-id list, driver can also autodetect any new wireless RNDIS device.

===== what works =====
    * unencrypted networks 
    * WPA/WPA2 PSK/Enterprise 
    * WEP should work 
    * ad-hoc should work, unencrypted and WEP 
    * hidden networks, unencrypted and WEP 
===== what does not =====
      * Hidden + WPA 
===== known problems =====
        * Driver has been tested with b-variant of chipset/firmware. Older devices with a-variant of chipset/firmware used to operate poorly with this driver but this should be resolved on newer kernels (>=2.6.32). 
        * The driver included in kernels <= 2.6.37 shows very few scan results with a-variant devices. Workaround this by configuring the device statically (e.g., /etc/network/interfaces or by issuing iwconfig/dhclient right after boot). Do not rely on a beacon being detected to determine if a network is available or not --- this is [[en/users/Documentation/NetworkManager|NetworkManager]]'s approach, which can make it take hours until it detects and configures an available network. This issue should be resolved in kernel version 2.6.38.
