Note: You have to be sure that Wireless Tools are installed on your rootfs before going further. |
Tested hardware
Ralink RT2571WF
The WiFi chipset RT2571WF can be found under the D-Link WiFi key DWL-G122. All drivers are included in Linux kernel 2.6.27. But firmware must be downloaded from serialmonkey website at this address.
To use it with APF9328, you need an APF9328DevFull development board (with USB Host).
Kernel configuration
- First, to use a USB dongle, USB Host must be configured. See this page to know how to do with the APF9328DevFull.
- Then, Wireless network must be configured selecting these options in make linux-menuconfig:
[*] Networking support --->
Wireless --->
<*> Generic IEEE 802.11 Networking Stack (mac80211)
- Finally, select the chipset :
Device Drivers --->
[*] Network device support --->
Wireless LAN --->
[*] Wireless LAN (IEEE 802.11)
<M> Ralink driver support
<M> Ralink rt2501/rt73 (USB) support
WiFi configuration
First mount the module:
# modprobe rt73usb
Then copy the firmware named rt73.bin (found in Module directory of rt73-cvs archive) in apf /lib/firmware directory. If /lib/firmware doesn't exist create it.
mkdir -p /lib/firmware tftp -g -r rt73.bin <yourIP> mv rt73.bin /lib/firmware
Your WiFi-module driver is ready, you can now connect the dongle and after go further with the WiFi configuration.
ZyDas zd1212 chipset
- Tested with SMC WUSB-G (which is in the compatibility list).
- Go here to buy this device in France (LDLC)
- Other ways to get it ?
Configure Linux
$ make linux26-menuconfig

<M> ZyDAS ZD1211/ZD1211B USB-wireless support
[*] ZyDAS ZD1211 debugging
$ make linux26 && make
Reinstall your system.
Get firmware
- http://zd1211.ath.cx/get-firmware
- copy the archive to your TFTP export directory
Install firmware on your APF
# mkdir -p /lib/firmware/ # cd /lib/firmware/ # tftp -g -r zd1211-firmware-1.4.tar.bz2 192.168.0.17 # bunzip2 zd1211-firmware-1.4.tar.bz2 # tar xf zd1211-firmware-1.4.tar # mv zd1211-firmware zd1211
Connect your USB adapter
