Procedure to Enable Wireless USB Adapters on Electrum

1) Make sure that the Kernel has Configurations to enable Wireless USB. ( In this example RT2X00, RT73USB, ZD1211 modules are enabled.)

CONFIG_CFG80211=y

CONFIG_NL80211=y

CONFIG_WIRELESS_EXT=y

CONFIG_WIRELESS_EXT_SYSFS=y


CONFIG_MAC80211=y

CONFIG_MAC80211_RC_PID=y

CONFIG_MAC80211_RC_DEFAULT_PID=y

CONFIG_MAC80211_RC_DEFAULT="pid"

CONFIG_WLAN_80211=y


CONFIG_RT2X00=m

CONFIG_RT2X00_LIB=m

CONFIG_RT2X00_LIB_USB=m

CONFIG_RT2X00_LIB_FIRMWARE=y

CONFIG_RT2X00_LIB_LEDS=y
 

CONFIG_RT73USB=m

CONFIG_ZD1211RW=m

CONFIG_RT73USB_LEDS=y


CONFIG_CRYPTO=y

CONFIG_CRYPTO_ALGAPI=y

CONFIG_CRYPTO_BLKCIPHER=y

CONFIG_CRYPTO_MANAGER=y

CONFIG_CRYPTO_ECB=y

CONFIG_CRYPTO_AES=y

CONFIG_CRYPTO_ARC4=y

CONFIG_CRYPTO_HW=y

CONFIG_CRC_ITU_T=y

2) Start Electrum100 with new Kernel Build.

3) Update the list of available packages, then install the firmware-ralink, wireless-tools, wpasupplicant packages:

Electrum100~# apt-get update

Electrum100~# apt-get install firmware-ralink wireless-tools wpasupplicant

4) Add appropriate lines for your wireless network connection and restart the board.

Electrum100~# vi /etc/network/interfaces  
#Wirless USB
auto wlan0
iface wlan0 inet dhcp
wpa-psk password
wpa-driver wext
wpa-key-mgmt WPA-PSK
wpa-proto WPA2
wpa-ssid micromint

5) If not already performed, connect the device to your system.

The necessary kernel module should be automatically loaded. If necessary, it can be manually loaded using(example):

Electrum100~# modprobe rt73usb
