====== Dongly ======

{{:chumbyhackerboard:wn321g_lrg.jpg?500|}}

The Chumby hacker board does not have Wireless capability built in, but its very easy to add! The best dongle to use is the [[http://www.adafruit.com/index.php?main_page=product_info&cPath=47&products_id=283|TP-LINK TL-WN321G (or any other RT73-based dongle)]] which has drivers ready to go. Note that many dongles probably won't work - if you have one kicking around you can try it but don't be surprised when it is not recognized!

<if you know of an adapter that does/doesn't work, you should post it here>

====== Connecting to your WiFi network ======

Plug in the dongle

Run **iwconfig wlan0 scan** to list all the local networks

Riotstarter: this should be **iwlist wlan0 scan**

{{:chumbyhackerboard:iwlist.gif|}}

Find your network, we'll connect to **adafruit** (not listed here, just substitute your own connection name)

Configure the wlan adapter (we'll be using WEP here, WPA is more complex)
  * Set the WiFi password with **iwconfig wlan0 enc XXXXXXXXXX** where XXXXXXXXXX is your 10 digit hexadecimal WEP password (ps. our password isnt really DEADBEEF00)
  * Set the channel to match the one in the **iwlist** output with **iwconfig wlan0 channel NN**
  * Set the network you want to connect to with **iwconfig wlan0 essid adafruit** where **adafruit** is substituted with your network name

You should get a **[ 1932.400000] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready** response from the kernel

====== Start DHCP ======

DHCP will let you get your IP, route and DNS right from the router

You'll need to remount root so that dhclient can edit it

Start up the **wlan0** connection

{{:chumbyhackerboard:ifconfigup.gif|}}

Then run **dhclient wlan0** (the image doesnt show the **wlan0** because I had already run dhclient to do this tutorial, make sure to stick the **wlan0** part on!)

{{:chumbyhackerboard:dhclient.gif|}}

You should be able to ping!

====== Set up IP & DNS ======

Say you don't have DHCP or don't want to use DHCP for some reason.

Pick an IP address, and **ifconfig wlan0 <ipaddress> up** to give yourself an IP address

Don't forget to add a default route, through your router

{{:chumbyhackerboard:addroute.gif|}}

If you want DNS you'll have to remount the root directory **rw** and edit **/etc/resolv.conf**

{{:chumbyhackerboard:iwremount.gif|}}

If you need to, set up your **resolv.conf** so that you have one or two DNS servers in there

{{:chumbyhackerboard:resolvconf.gif|}}

When you're done, be tidy and remount / as read only, k?
