I got a USB wifi for my raspberry pi 2, this way I can keep my pi2 in my room where my monitor is so that if I need to plug it in to my monitor it would be easier.
Although the wifi dongle was plug and play, I had issue with getting it to work as per the instructions on the official documentation page clickme
Instead, the following steps worked for me :
- First verify that device is actually working by typing in
$ lsusb Bus 001 Device 005: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Make sure that the device interface is up if not then
$ ifup wlan0
Inorder for me to get it to work I had to change the
add the following lines:
allow-hotplug wlan0 auto wlan0 iface wlan0 inet dhcp # wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf wpa-ssid "ssid-name" wpa-psk "password"
You can use
$ iwlist wlan0 scan(you may need sudo in some cases depending on the kind of user you are.)
to find out the ssid for you wifi.
