Connect to Wifi from Command Line only

location: ubuntuforums.com - date: January 13, 2011
Hello everyone, I want to connect to my wifi from command line (not the one you enter from ALT+CTRL+F1, BUT the one you enter from Recovery Mode). When I go to Recovery Mode --> Switch to room command line with networking IF I use ethernet (eth0) I have no problems. And even if I plug the ethernet wire AFTER the login and then I run "sudo dhclient" I get the internet connection. BUT IF I want to connect to my wireless network it doesn't work. I have tried with this (and many other) syntax: sudo iwconfig wlan0 mode managed channel 6 key open essid MyNet sudo iwconfig wlan0 ap AA:BB:CCD:EE:22 sudo dhclient wlan0 BUT I get something like this (I cope/pasted the result from another website. But the result it's this one) Listening on LPF/eth0/00:20:e0:5e:2d:73 Sending on LPF/eth0/00:20:e0:5e:2d:73 Sending on Socket/fallback DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 4...

This article shows how to disable/enable Wireless network connection(WiFi) on a windows system from command line. We can also find the status of network connections, check if they are connected or disconnected.

Disable WiFi from command prompt

Open elevated administrator command prompt and run the below command to turn off WiFi

netsh interface set interface name="Wireless Network Connection" admin=DISABLED

After running the command, you can immediately see in System tray (Right bottom corner on your windows screen) that WiFi is disconnected. In network connections, it shows it as disabled.

How to enable WiFi connection

Run the below netsh command to turn on Wifi connection from command line.

netsh interface set interface name="Wireless Network Connection" admin=ENABLED

In a nutshell, I need to connect to my wireless network from the command line.

I normally use WPA encryption, but I can easily disable it, so assume no security at all.

This is a problem I've run into before. I'll boot SliTaz on a computer with no Ethernet adapter, run into some kind of display problem, and need to run tazx in text mode and install graphics drivers. But, because I have no wifi connection, and no way to create one, tazx is essentially useless.

Seems this should only require a few simple commands, but extensive searches have yielded no results. On Ubuntu, I believe the commands are:

sudo ifconfig wlan0 up
sudo iwconfig wlan0 essid "xxxxxx"
sudo dhclient wlan0

On SliTaz, the third command fails, because SliTaz uses udhcpc instead of dhclient.

I can't be the first person to have run into this problem. Any idea what the commands might be for...

Why use a friendly GUI when there’s cryptic shell commands out there?

Phoenix Coffee offers free wireless access without an access key and they broadcast their ESSID. Here’s how I connect:

$ sudo iwlist eth1 scan # eth1 is my wireless card.
eth1 Scan completed :
Cell 01 - Address: 0A:1D:19:15:C2:C1
ESSID:"bestcoffee"
Mode:Master
Channel:5
Frequency:2.432 GHz (Channel 5)
Quality=88/100 Signal level=-44 dBm Noise level=-81 dBm
Encryption key:off
Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 6 Mb/s
9 Mb/s; 12 Mb/s; 18 Mb/s; 24 Mb/s; 36 Mb/s
48 Mb/s; 54 Mb/s
Extra:tsf=0000003befa89182

That scan lists every available access point. The important piece of information to extract here is the ESSID. Now I set my wireless card up to connect to that ESSID:

$ sudo iwconfig eth1 essid "bestcoffee"

And finally, I tell my card to request an IP address from the router:

$ sudo...

I bought a new Netgear wireless router last week. I was wondering if there is any utility to monitor wifi connection. After a bit of search on Google, I found a feasible solution that worked perfectly as I expected. I would like to share it with our readers. Meet Wavemon, a simple wireless network monitor that can be used to monitor your wifi network connection from Terminal in Linux. It is an ncurses-based monitoring application that can be used to monitor your wireless network’s signal and noise levels, packet statistics, device configuration and network parameters etc. It will work with almost all type of wireless devices supported by the Linux kernel. Wavemon is freely distributed under the GNU general public license v3. That means you can use it for free, distribute and modify the code.

In this short tutorial, we are going to see how to monitor your wifi connection from Terminal with few practical examples.

How To Connect To A WPA Wifi Using Command Lines On Debian

This tutorial will explain how to connect to a WPA (1-2) wireless network without installing any graphical tool.

I assume that your wireless drivers are activated in the kernel and that your card is detected in Linux with the command:

ifconfig -a

Mine is identified by wlan0 but that may change for you.
For Intel users, you may need firmware-iwlwifi from the non-free repository.

For the others let's install wpa support now if you don't have it (you probably have it if you got a graphical interface):

aptitude search wpasupplicant

If there is an "i" in front of wpasupplicant, then it's installed otherwise do:

aptitude install wpasupplicant

Then we will configure a network, so we create and modify the configuration file:

vim /etc/wpa_supplicant.conf

Complete the file to make it look like that (replacing wifi_name and wifi_key by their...
