Getting wifi to work

[classof1980]

I’m trying to get wifi to work on a rpi2 with just retropie. So far this is what I did was edit
sudo nano /ect/network/interfaces

To

auto lo

Iface lo inet loopback
Iface eth0 inet dhcp

Allow-hotplug wlan0
Auto wlan0
Iface wlan0 inet dhcp
Wpa-ssid “my network name”
Wpa-psk “my password”

this does not seem to be working any ideas?

A couple things to check-

-WiFi dongle compatibility:
http://elinux.org/RPi_USB_Wi-Fi_Adapters
– case sensitivity: make sure that everything is the right lower and uppercase values
– did you reboot? Changes won’t take effect until you either restart network services or reboot your pi.

See this video for a step by step setup:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf 

Go to the bottom of the file and add the following:

network={
    ssid="hostname"
    psk="Your_wifi_password"
}
