One of the first things you should do once you have your Raspberry Pi is setup a wireless network adapter. This will allow you to be cable free. To configure, you will need one of several approved USB wireless adapters. I’m using an Airlink 101 Wireless N 150 Ultra Mini-USB Adapter that I purchased at Amazon for just $14. I chose the Airline 101 because it was affordable, and it works very well with the Raspberry Pi.
10 steps to setup wireless on Raspberry Pi:
- Plug in the Airlink 101 adapter.
- Power up the the Raspberry Pi.
- To see if the wireless device is recognized, type lsusb.
- To see if the kernel driver is installed, type lsmod.
- Edit the /etc/network/interfaces file.
- Edit the /etc/wpa_supplicant/wpa_supplicant.conf file.
- Reboot.
- Check with ifconfig.
- Check with ping.
- All done.
Here are the commands, instructions and their respected screen outputs.
