Linux commands for network

I want to remember some basic commands I used while configuring the network on my laptop.

I install the network tools typing:

sudo apt install net-tools

See the name of the network typing:

iwconfig

I start up the network typing:

sudo ifconfig nameOfNetwork up

Operation not possible due to RF-kill

This command shows the devices availability status:

sudo rfkill list all

Typing:

sudo lshw -class network

you can take note of the driver name:

driver = iwl3945

Important, check that the physical wireless button of the Lenovo is “ON”
