This is an old revision of the document!
The Chumby hacker board does not have Wireless capability built in, but its very easy to add! The best dongle to use is the 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:
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 /
The TP-Links changed from RT73 to RT2800. You can tell which is which because when you plug in the RT2800 a green LED lights up in the casing.
Download this compressed file RT2800 Kernel module update. Uncompress it and put it on a USB key. Plug the USB key into the CHB and copy it to /mnt/storage:
$ cd /mnt/storage/ $ mount -oremount,rw / $ cp /mnt/usb-XXXXX/update-modules.sh . $ ./update-modules.sh
Reboot, then follow the rest of the tutorial!
Plug in the dongle
Run iwlist wlan0 scan to list all the local networks
If you don't get anything, check dmesg in case you dont have the driver necessary, this can be a little confusing. See the driver list above. 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)
You should get a [ 1932.400000] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready response from the kernel
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
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!)
You should be able to ping!
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
If you want DNS you'll have to remount the root directory rw and edit /etc/resolv.conf
If you need to, set up your resolv.conf so that you have one or two DNS servers in there
When you're done, be tidy and remount / as read only, k?
In this post by ChumbyLurker you'll find an easy way to configure your wireless, WPA and all.
