 * Some devices might display very [[https://bugzilla.kernel.org/show_bug.cgi?id=20822|poor scan results]] (resolved since Linux 2.6.38), making NetworkManager and similar programs take a long, long time to detect a given network. A possible workaround to improve the time to configure the device at boot-time is to ''pre-configure'' the connection manually on the {{{/etc/init.d/networking}}} file. For example: {{{
case "$1" in

        process_options

        log_action_begin_msg "Configuring network interfaces"
        #workaround WUSB54GS's low performance on scan
        iwconfig wlan0 essid MYESSID
        iwconfig wlan0 key MYKEY
        iwconfig wlan0 channel NN
        dhclient wlan0 &
        if ifup -a; then
            log_action_end_msg $?
(...)
}}}
 NetworkManager will then see the network's beacon much quicker and will be able to configure the device appropriately afterwards.

rndis_wlan is a Linux kernel driver introduced at Linux 2.6.25, supporting wireless RNDIS1 chips; the Broadcom BCM4320 is the only one known at this time. Supported devices are listed at the end of this page.

No firmware from userspace is required.

Installation

  1. Connect the device to the system. The rndis_wlan kernel module is automatically loaded for supported devices.

  2. Configure the wireless interface as appropriate.

Troubleshooting

  • This driver does not support connections to hidden WPA networks at this time.

  • If attempting to use a Belkin F5D7051 v1000 device (USB ID 050D:7051), blacklist the rt2500usb module and execute modprobe -r rt2500usb to unload it.

  • Known problems with this driver are documented on its homepage.

Supported Devices

The page HowToIdentifyADevice/USB explains how to identify a USB device.

The following list is based on the alias fields of modinfo rndis_wlan in Debian 3.2.0 (3.2.46-1) kernel images.

rndis_wlan can autodetect newer RNDIS devices not listed above.

Unsupported Devices

  • Belkin F5D7051 v3000 (USB ID 4317:0711, Broadcom BCM4326U)

  • Linksys WUSB54GSC v2 (USB ID 1737:0075, Broadcom BCM4326U)

  • TiVo Wireless G USB Adapter (AG0100: USB ID 0A5C:BD11)2

Support for these devices may be possible using NDISwrapper.
