So you just bought your pi with wheezy and you’ve purched a usb dongle…
First off, you should upgrade all your shit…always, unless you have crazy stuff that depends on other stuff being old and stuff…
sudo apt-get update sudo apt-get upgrade
Next reboot your pi.
sudo reboot
Have a look around then alter:
sudo nano /etc/network/interfaces
If you’re finding it hard to type characters in the next section because your keyboard map is off, do this and reboot
sudo dpkg-reconfigure keyboard-configuration
To look like this (provided your have DHCP on your network, if you can’t figure it out look here.):
auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 auto wlan0 iface wlan0 inet dhcp wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
Next we’ll setup wifi and configuration (I’m getting this from this guy). Then we’ll install ssh so we don’t need that hefty HDMI cable anymore and you can remote into your pi. But first we need to get it working…
Insert the following into your supplicant conf file by typing
sudo pico /etc/wpa_supplicant/wpa_supplicant.conf
And insert the following
network={
ssid="SSID-GOES-HERE"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP
psk="WIFI-PASSWORD-GOES-HERE"
}
If you need to know what’s on your network try this
sudo iwlist wlan0 scan
Make sure you’ve also removed anything pertaining to wlan0 in your 70-persistent-net.rules files
Once we’ve got our configuration correct shut down your system.
sudo shutdown -h now
Unplug your ethernet and turn your pi back on.
Log in to your system and type
iwconfig
You should see that you’re associated with your network. If you’re not and you have a realtek wifi dongle, look here. Basically you just need to install the firmware for your device.
You can also restart your network by issuing the following
sudo /etc/init.d/networking restart
UPDATE:
I had some problems getting the above to work properly. I followed this tutorial and it worked for me: http://kerneldriver.wordpress.com/2012/10/21/configuring-wpa2-using-wpa_supplicant-on-the-raspberry-pi/
Make sure if your wifi adapter isn’t coming up automatically, that you bring it up manually:
sudo ifup wlan0
I actually also changed everything to what “peppertarts” says here. So make sure you disregaurd the above if it doesn’t work for you basically all you need is:
sudo nano /etc/network/interfaces
and insert
auto wlan0 iface wlan0 inet dhcp wpa-conf /etc/wpa.conf
at the end of the file, then
sudo nano /etc/wpa.conf
And finally
network={
ssid="NETWORK_SSID"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP
psk="NETWORK_PASSWORD"
}
Then type
sudo ifup wlan0
and reboot after you make sure its running. Pretty simple after all that work. Either way, make sure your wifi works before you try to install ssh and run it
Installing SSH
So we don’t need to always have our pi plugged into an HDMI capable screen, we can ssh into our pi. This is useful especially when we want to remove peripherals like our mouse and keyboard to make room for other devices like wifi dongles etc. We’ll need to install ssh to allow us to log in remotely
sudo apt-get install ssh
Then start the daemon
sudo /etc/init.d/ssh start
Next we need it to run on startup
sudo update-rc.d ssh defaults
After rebooting you should see your PI’s IP address. This will tell you that its working.
Just to recap:
- Make sure your wifi adapter is working and automatically connecting to the network on startup
- Install ssh on your pi
- Find your pi on the network and have fun!
