Cannot connect Pi 3 to internet

Question

My son and I are complete newbies when it comes to pi and Raspbian. We've just bought a pi 3 and have set up Raspbian from Noobs. We can connect to our router using both WiFi and Ethernet but cannot connect to any sites using the browser. The router is working normally with other devices. I'm inclined to think the pi is faulty, but looking for suggestions to try before I send it back.

Answer 1

I'm sorry to hear that you're having issues using your Pi, but again it is highly unlikely it is defective. Try connecting a display to it, as well as any USB keyboard. Once you have done that, startup your Pi by connecting any Micro-USB cable to your Pi. If you cannot connect a display to your Pi, connect it to your router via Ethernet and connect it to your keyboard and power supply.

• Type sudo apt-get install ssh

Download and install Putty, and I recommend using Fing on the App store to locate your Pi's IP address. When that's done, insert the IP address of your PI into Putty, and continue on to the next steps.

Login (if prompted):

Username: pi

Password: raspberry

Type:

• sudo nano /etc/network/interfaces

Make sure your screen looks like this, if not type it in.

When you're done doing that, press Control+X, type y, and press enter.

Now, for the final part, type:

• sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

This time, add the following to the file:

network={
    ssid="Network Name"
    psk="Network Password"
    proto=RSN
    key_mgmt=WPA-PSK
    pairwise=CCMP
    auth_alg=OPEN
}

Tip: the name and password is case sensitive, so type it exactly as it appears.

When you're done, press Control+X, type y, and press enter again.

Now you're ready, type sudo reboot now and enjoy your internet-connected Pi!
