+====== 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:
+  * Works - RT73 based:
+    * Hawking HWUG1 with external antenna adapter. FCC ID: NDD957318S607
+    * <yours here>
+  * Works with alternate driver:
+    * [[http://www.dealextreme.com/details.dx/sku.48166|This]] mini-dongle works using [[http://junk.kanniets.nl/files/8192cu.ko|this]] module.
+    * <yours here>
+  * Doesn't work
+    * <here>
+Download the module and copy it to your chumby, say /mnt/storage/. Then run the following commands.
+  $ cd /mnt/storage/
+  $ mount -oremount,rw /
+  $ install -p -m 644 8192cu.ko /lib/modules/2.6.28-chumby/kernel/drivers/net/wireless/
+  $ depmod -a 2.6.28-chumby
+  $ mount -oremount,ro /

 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
+  * 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
+{{:chumbyhackerboard:iwremount.gif|}}
+Start up the **wlan0** connection
-{{:chumbyhackerboard:iwremount.gif|}}
+{{: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!

-{{:chumbyhackerboard:ifconfigup.gif|}}
+====== 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
 {{:chumbyhackerboard:ifconfignodhcp.gif|}}
+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:dhcpdwlan0.gif|}}
+{{: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?

+====== "Easy" way ======
+In [[http://forum.chumby.com/viewtopic.php?pid=31627#p31627|this]] post by ChumbyLurker you'll find an easy way to configure your wireless, WPA and all.
