My new raspberry pi is unable to connect to the internet. I got a dongle provided from with the pi itself so it should not have any compatibility issues. The network icon shows 'wlan0: Not associated' when I try to connect. I followed some posts on the internet and went to nano /etc/network/interfaces and changed it to

auto lo iface lo inet loopback

iface eth0 inet dhcp

auto wlan0 allow-hotplug wlan0 iface wlan0 inet dhcp wireless-essid "WiFiName" wireless-key "password"

according to one of the post said. I don't have a password so I left that part "". Still I am unable to connect. Please help!!

This often happens if the power supply to the RPi is not powerful enough.

A standard 0.5Amp USB is not enough to drive a Pi with a Wifi dongle.

My tip, make sure you get a sufficiently powerful power-supply for the Pi.


If you didn't fiddle with the files it may work. Put them back the way they were. The following shows the correct file contents (as well as how to setup).

How do I set up networking/WiFi/static IP address?

NOTE If you don't know the password you won't be able to setup.
