How to identify the Wireless LAN device on an XO:

  • get to the Ok prompt,
  • follow the appropriate section below,

Display the MAC address

Type this:

select /wlan:force  .properties  unselect

Examine the output, for example:

mac-address              20 16 d8 1e 88 2b 
local-mac-address        20 16 d8 1e 88 2b 
device_type              wireless-network
name                     wlan
reg                      00000001 00000001 

The mac-address property is six hexadecimal numbers separated by spaces. In this example, the MAC address is 20:16:d8:1e:88:2b.

Check the card model

On XO-1, type this:

select /wlan:force  .properties  unselect

On XO-1.5, XO-1.75 or XO-4, type this:

select /wlan:force  unselect
dev /wlan  dev ..  .properties  dend

Examine the output, for example:

assigned-address         00010000 
module-type              mv8787
#address-cells           00000001 
#size-cells              00000001 
name                     sdio

The module-type property will be either:

  • mv8388 for the USB 802.11g 2.4 GHz WLAN card, used in XO-1,
  • mv8686 for the SDIO 802.11g 2.4 GHz WLAN card, used in XO-1.5, XO-1.75, or XO-4 or
  • mv8787 for the SDIO 802.11n 2.4 GHz and 5 GHz combination WLAN and Bluetooth card, available for XO-4 only.
