Not too difficult. From command line:
sudo nano /etc/network/interfaces
Near the bottom add the following lines:
allow-hotplug wlan0 auto wlan0 iface wlan0 inet dhcp wpa-ssid "whatever your ssid is" wpa-psk "your network password"
Ctrl-x to exit nano, it will ask you to save. Just hit Y and then enter to accept the filename. Reboot your pi using:
What I also did that helps is tell raspberry pi to reconnect to my wifi in case I do something stupid like reboot my router. Here’s what I did.
sudo nano ./wifi_checker.sh
Inside good ol nano I used this script:
#!/bin/bash if ! ifconfig wlan0 | grep -q "inet addr:" ; then ifup --force wlan0 sleep 10 fi
Save and exit like you did before. Then:
sudo chmod +x ./wifi_checker.sh
Next you want to schedule that to run to check the status of your wifi connection. To that we go to crontab.
sudo crontab -e
Go to the bottom and enter the following line:
*/5 * * * * ~./wifi_checker.sh
Exit and save and you should be good to go.
