[Home] Setting up Wifi on Gumstix Overo Fire


Create a Gumstix experience that I can live with.

This is going to live in my living room accessible via wireless

Setup with the Out-of-Box system

First Things First

# secure my gumstix from netbots (it will have a public IP)

# make vim usable
echo ":set nocompatible" >> /etc/vimrc

# make the filesystem searchable with locate

Wireless Networking

Disable Bluetooth

# (disable) bluetooth 
/etc/init.d/bluetooth stop
echo 0 > /sys/class/gpio/gpio164/value # reset
echo 0 > /sys/class/gpio/gpio15/value  # disable
update-rc.d -f bluetooth remove
update-rc.d -f blueprobe remove

Errors You may Encounter

# This helps... kinda... I think, but it may be solely the manual config below that gets it working
/etc/init.d/NetworkManager stop
update-rc.d -f NetworkManager remove
opkg remove networkmanager network-manager-applet


can't create /var/lib/dhcp/dhclient.leases: No such file or directory


ln -s /var/lib/dhcp3 /var/lib/dhcp

Enable WiFi


ESSID='Apt Rm 04 & 05' # CHANGE THIS to suite your situation
ifdown -a
ifconfig wlan0 down
iwconfig wlan0 bit 18M fixed
iwconfig wlan0 essid "${ESSID}"
iwconfig wlan0 mode managed
iwconfig wlan0 key off
dhclient wlan0


allow-hotplug wlan0
auto wlan0
iface wlan0 inet dhcp
        pre-up iwconfig wlan0 mode managed
        pre-up iwconfig wlan0 essid "Apt Rm 04 & 05"
        pre-up iwconfig wlan0 key off

This also works, note that there are no quotes:

allow-hotplug wlan0
auto wlan0
iface wlan0 inet dhcp
    wireless_mode managed
    wireless_essid Apt Rm 04 & 05
    wileless_key off

Better(?) Marvel Firmware

wget http://old.nabble.com/file/p29272793/Marvell_firmware_9.70.7.zip
unzip Marvell_firmware_9.70.7.zip
locate sd8686
mv 9.70.7.p0/sd8686-9.70.7.p0.bin /lib/firmware/sd8686.bin


I have a dd-wrt router on which I added my Gumstix to have a static IP and be the DMZ.

  1. Log in to dd-wrt
  2. Click services
  3. Click add under DHCP Server
  4. Enter the gumstix hwaddr, and desired hostname and desired ipaddr
  5. 'save' first (do NOT apply first)
  6. okay, now 'apply'
  7. Click NAT/QoS
  8. Click DMZ
  9. Add gumstix
