How To: WiFi on your Raspberry PI ?
The Raspberry Pi has many great features straight out of the box, unfortunately WiFi is not one of them, in this guide I’ll show you how I WiFi equipped my Raspberry PI for only a fiver.
We will be assuming that you have a head less setup (without a monitor) so the guide should work for everyone, either via SSH (remote) or via a local terminal session if you do have a monitor.
Also its worth noting that some WiFi adapters will require a powered USB hub between the Raspberry PI and the USB module, the one used below doesn’t due to it’s power consumption assuming you don’t have anything else drawing large currents from the USB power.
1. What you will need…
1) Raspberry Pi, with Wheezy
2) Internet Connection (via the ethernet port to begin with)
3) WiFi network to test on
4) USB WiFi Dongle (all our usb wifi dongle can work)
2. Update the OS
There are so many times you will run into a bug when installing something new and find out that it would have worked if your system was up to date, taking no risks here so get your system updated
Due to the RAM/CPU power on the Pi’s, this might take a while, brew anyone?
3. Reboot
Power down the device, install your WiFi USB module and turn it back on.
4. Setup the interface configuration
1 | sudo nano /etc/network/interfaces
Normally your base configuration will look something like this
1 | auto lo
2 |
3 | iface lo inet loopback
4 | iface eth0 inet dhcp
5 |
6 | allow-hotplug wlan0
7 | iface wlan0 inet manual
8 | wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
9 | iface default inet dhcp
Assuming you have a DHCP server on your LAN (normally your DSL/Cable router) use the following configuration, your SSID and password will be put in the wpa_supplicant.conf later on in this guide.
1 | auto lo
2 |
3 | iface lo inet loopback
4 | iface eth0 inet dhcp
5 |
6 | allow-hotplug wlan0
7 | auto wlan0
8 | iface wlan0 inet dhcp
9 | wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
If you don’t have a DHCP server, or if you want to just statically assign the IP address you can use the following, however update the IP, Netmask and Gateway to match your network.
1 | auto lo
2 |
3 | iface lo inet loopback
4 | iface eth0 inet dhcp
5 |
6 | allow-hotplug wlan0
7 | iface wlan0 inet manual
8 | address 192.168.0.100
9 | netmask 255.255.255.0
10 | gateway 192.168.0.1
11 | wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
5. Setup the WPA configuration
Finally you will want to edit the WPA configuration as below, don’t forget to update it for your SSID and WPA password!
1 | sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
1 | network={
2 | ssid="SSID-GOES-HERE"
3 | proto=RSN
4 | key_mgmt=WPA-PSK
5 | pairwise=CCMP TKIP
6 | group=CCMP TKIP
7 | psk="WIFI-PASSWORD-GOES-HERE"
8 | }
6. Final Reboot
Ok that should be it, do a final reboot remove the wired ethernet cable and your IP should automatically come onto the network as a normal WiFi device.
Product Description:
COMFAST CF-WU810N is the Realtek RTL8188CUS 150Mbps most fashionable usb wireless adapter for android and Raspberry Pi, smallest invisible super mini outside design, small and exquisite, it won′t take much room to use and it is very convenient to take along.
It built in smart antenna, can sharply strengthen the wireless signals receiving ability, wireless stability and signals covering range.
CF-WU810N usb wireless adapter for android and Raspberry Pi adopts the newest network transmission technology IEEE802.11N and Green WLAN, transmission rate up to 150Mbps. Compare with the traditional 54 Mbps 11G products, it has more wireless bandwidth, making the LAN data transmission higher efficiency, it can reduce the network delay, make the voice and video chat and Video-On-Demand more fluent. At the same time, it can support wireless roaming, guarantee the wireless connecting.
CF-WU810N usb wireless adapter for android and Raspberry Pi also adopts the newest International wireless CCA(Clear Channel Assessment)channel detecting technology, When it detected out that its around has wireless signals disturbing, it can adapt itself to the frequency mode automatically, avoiding other channels disturbing and making the wireless signals more stable. When the disturbing disappear, it can tied up the leisure channel again, promoting the wireless performance.
Besides, it also can support WMM audio/video priority function, making the media audio/video transmit more fluently. This invisible wireless adapter can be a WIFI emitter, connecting with other pc and shared the WIFI wireless network.
