Are you connected to the router? ping -c 3 router. If not out put of ip link

Are they the correct settings for your set up? or have you just copied from book?

I'm pretty sure your network interface is not etch0.

Well 1st you need to get the settings "ip address" of router, then you need to post output of

Code:

ip link

or just use the info you get from those to adjust your ifconfig file

There are no devices found, missing drivers or firmware

Hello thanks for the reply,

can you suggest me what i need to set and install?

spiky0011 · 09-12-2016, 12:56 PM

No as I dont know what hardware you have it will need building in the kernel and you need to find out if it needs firmware and install it into /lib/firmware, You must start looking and doing some of this yourself, or show what you have tried.

You need to know what internet device you want to use, ethernet or wireless. You then need to know what the device is. You will then need to build the drivers for it into the kernel, and find out if firmware is required for your device,

2 tools to help you find out the info are

Code:

lspci

Code:

lsusb

and google
