Configure Wifi

If you have a wifi adapter compatible with Raspberry PI and Raspbian you can easily setup it to access the internet via wireless. You only need to change/check a couple of files, so you need to SSH into your Minera system or login with a monitor and keyboard connected. When you are ready, first of all, check your interfaces file:

sudo vi /etc/network/interfaces

The file should contain these lines:

auto lo

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp

Now, your interfaces are configured, you have to configure the wpa_supplicant with your wifi info (SSID and WPA), edit this file:

sudo vi /etc/wpa_supplicant/wpa_supplicant.conf

It should contains lines like these, but of course change the relative ones with your config:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="<YOUR-SSID>"
    psk="<YOUR-PASSKEY>"
    proto=RSN
    key_mgmt=WPA-PSK
    pairwise=CCMP
    auth_alg=OPEN
}

Of course you should also check what kind of auth protocol your wifi AP uses, but this configuration is almost a standard.

Now, reboot your system and you should be ready and connected via WiFi, to check it, run:

sudo iwconfig

And you should see something like this:

wlan0     IEEE 802.11bgn  ESSID:"<YOUR-SSID>"  Nickname:"<WIFI@REALTEK>"
          Mode:Managed  Frequency:2.437 GHz  Access Point: 90:72:40:0E:19:E4
