Configuring my wifi dongle on the Raspberry Pi to connect to my network router.

Configuring my wifi dongle on the Raspberry Pi to connect to my network router.

Generic Wifi dongle used on my Raspberry Pi

I had to get my router details and had to configure the following configuration files.
I wanted to give my Raspberry Pi a spear static IP so I always know what it is on my network.

I edited the following files.

/etc/wpa_supplicant/wpa_supplicant.conf

I added the following at the end. I was using WEB encryption and shared key on my router.

Change the details in yellow for your router if you use web encryption with shared key.

use your favorite editor

sudo vi /etc/wpa_supplicant/wpa_supplicant.conf

#Configeration of the file /etc/wpa_supplicant/wpa_supplicant.conf

country=GB

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

update_config=1

network={

        ssid="MyRouter"  # your router ID

        key_mgmt=NONE

        wep_key0="0123456789123"  # or 13 characters, or a hexkey starting with 0x your key

        wep_tx_keyidx=0

        auth_alg=OPEN

}

Save and exit

And the change the following file

Edit the file as follows in the section configuring wlan0

I gave my Raspberry pi a spear static Ip on my network so always now what the ip is and don't use DHCP so I will not know what the Ip will be 

use your favorite editor

sudo vi /etc/network/interfaces

auto wlan0

allow-hotplug wlan0

#iface wlan0 inet dhcp

iface wlan0 inet static

address 192.168.1.205  #Static Ip

netmask 255.255.255.0 # Ip mask of network

gateway 192.168.1.254 # IP gateway of router

wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

iface default inet dhcp

Save

And reboot Raspberry Pi  sudo shutdown -r 0

ping your new Ip on Wifi network

ping 192.168.1.205

And it should now work.
