Wireless and Local network configuration in Ubuntu Linux

Hello Dear Readers:

The first thing to know and remember is that the Configuration network file is in pwd: /etc/network/interfaces

so, the first step:

1. You have to access and write your lines to configure your network here: gedit /etc/network/interfaces

#auto eth0

#iface eth0 inet dhcp

auto ra0 --- reference to the step 3.2

iface ra0 inet dhcp

eth0 reference to the local network and ra0 to the wireless network, both configuration lines above are using DHCP server , who is a common way to connect by using a Modem and a Router.

For eth0 static:

iface eth1 inet static
address 192.168.0.1
netmask 255.255.255.0
auto eth1

2. For activate eth0 you should uncomment the lines:

auto eth0 iface eth0 inet dhcp

and then write in the terminal console: sudo ifup ra0, sudo ifup eth0 respectively.

also you can do this to update the interfaces with the options that were introduced:

sudo /etc/init.d/networking restart

3. For activate ra0 follow the next steps

3.1 you should get the drivers depending on your network card

3.2.active the network by the last step

3.3 configurate the network with the unique features that you have

3.1.

You can look at this page, to get your driver ra0 connection: http://www.conocetupc.cl/te-ayudamos-ubuntu-faq/25-sobre-ubuntu/49-instalar-driver-dlink-tred-pci-wireless-dwa-525-en-ubuntu.html

Instalar driver DLink T/Red PCI Wireless DWA-525 en Ubuntu

Viernes, 09 de Septiembre de 2011

Para quienes se han comprado o estan pensando en comprar la tarjeta inalambrica DLink T/Red PCI Wireless DWA-525les aseguro que funciona en Ubuntu 10.04, Ubuntu 10.10 yUbuntu 11.04 a la perfección. La instalación no es muy complicada y se las detallare a continuación.

Lo primero que tenemos que saber es si Ubuntu esta detectando nuestra DLink T/Red PCI Wireless DWA-525, para hacer la exploración del hadware que Ubuntu detecta usaremos el siguiente comando en un Terminal (Aplicaciones > Accesorios > Terminal):

lspci | grep Network

Lo que hara es filtrar los componente de red, la salida del comando anterior debiera ser la siguiente

02.01.06 Network Controller Ralink 3060

Lo anterior es el chip que tiene la placa de red DLink T/Red PCI Wireless DWA-525. Ahoro todo lo que nos queda es proceder a realizar la instalación.

Abre un Terminal en el menu Aplicaciones > Accesorios > Terminal y puedes copiar y pegar los siguientes comandos

cd; wget http://www.conocetupc.cl/downloads/DWA-525.zip

El comando anterior descargar el driver DLink T/Red PCI Wireless DWA-525 para Ubuntu yGNU/Linux.

unzip DWA-525.zip

Con unzip descomprimes los archivos .zip y luego entraremos a la carpeta "driver" que es la decomprimida y compilaremos el driver con

cd driver; make

Luego que se haya compilado el driver instalamos con:

sudo make install

add this lines to sudo gedit /etc/modprobe.d/blacklist.conf

blacklist rt2800pci

blacklist rt2x00lib

blacklist rt2x00pci

blacklist rt2800lib

and then in “/etc/modules” add:

rt3562sta.kort3562sta




Luego reinicias tú Ubuntu

Here the process after unzip the driver package :

3.3

Go to System- preferences-network desktop menu- configuration after you have done the 3.2 step
