Start using Wi-Fi

Logged to a console type:

# loadwifi
# tail -t /var/log/message

Insert the WiFi USB adapter. You will see something similar to following messages:

crisv10_irq dbg: ctr_status_irq, controller status: host_mode started
crisv10_irq dbg: ctr_status_irq, controller status: host_mode started running

Exit from the tail command pressing CTRL-C and type:

# /etc/init.d/wireless start

 * Bringing up rausb0...
    + IP:
    + WEP: off
    + Channel: 1
    + ESSID: FOX
    + Mode: ad-hoc                                                      

The Wifi adapter will go up with the default IP address
Now see the TCP/IP configuration typing:

# ifconfig rausb0
rausb0    Link encap:Ethernet  HWaddr 00:17:9A:D0:12:EE
          inet addr:  Bcast:  Mask:
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0

          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:8034 (7.8 KiB)

And see the wireless configuration parms typing:

# iwconfig

we will investigate asap to update the driver inside the FOX Board SDK.

Configuring the WiFi adapter

The default configuration file of the WiFi adapter at the startup is /etc/conf.d/net.wireless. Let's look at its contents:

rausb is the device name of your WiFi adapter.


IP if the default IP address assigned to the adapter.
SUBNET is the subnet mask of your network.


ESSID is the Extended Service Set ID and identify the name of the wireless network. By specifying the ESSID you make sure that you connect to your wireless network instead of your neighbors network by mistake.


WIFI-DEFAULT tells is the WiFi adapter is the default gateway adapter and WIFI_GATEWAY indicates the IP address of the gateway on the network.

CHANNEL is the wireless channel that you want to use.


Set MODE="ad-hoc" to contact another host (another FOX Board for example) without using any Access Point .
Set MODE="managed" to link the FOX Board to Access Point.


This parm is the key to use in WEP encryption. When equal to "off" no encryptions is used.

Once you have changed the settings, you need to restart the wireless interface by executing the following commands.

# /etc/init.d/wireless stop
# /etc/init.d/wireless start

The wireless will be running with the new settings.
