How many of you failed to connect to WiFi network in Linux? Did you bumped into issues like the followings in different forums, discussion page, blogs? I am sure everyone did at some point. Following list shows just the results from Page 1 of a Google search result with “Unable to connect to WiFi network in Linux” keywords.Following guide explains how you can connect to a WiFi network in Linux from command Line. This guide will take you through the steps for connecting to a WPA/WPA2 WiFi network. In case you’ve only got wired connection only, you can use this guide to. You have really upped the knowledge level/detail since this site started great job I think it is great you focused on iw in this post.You should now try and do a primer on “ip” (as in ip link, ip addr, ip route, ip tunnel) that is a serious headache to try and figure out– even if taken in small chunks!One thing I am trying to right now is figure out how to create a bash script that creates a virtual wireless monitor, then changes the mac address on each to an identical new address.
Network Configuration Using the Command-Line Interface (CLI) The commands for the ip utility, sometimes referred to as iproute2 after the upstream package name, are documented in the man ip(8) page. The package name in Red Hat Enterprise Linux 7 is iproute. Setup Networking in CentOS 7. CentOS 7 has a wide range of tools that can be used to configure and manage networking, from manually editing the network configuration file to using commands such as ip, ifconfig, nmtui, nmcli or route. The easiest utility a beginner can use to manage and change network configurations is nmtui graphical command line. CentOS 7 comes with Network Manager, a service that runs by default and has a graphical, text as well as command line interface.You can use Network Manager to create, edit and remove interfaces and it can be used to configure Ethernet, WiFi, Mobile, DSL and PPPoE connections.
Part of figuring this out (while learning as much as possible), is to use the “iw” command instead of “airmon-ng”.Essentially, all airmon-ng really does is create an additional (virtual?) wireless interface using the same hardware NIC. So you can create this new interface with “iw dev wlan1 interface add mon1 type monitor” at the command line. (with “wlan1” being (for me) my Alfa wireless USB adapter). That command adds an interface called “mon1” and sets it to monitor mode (which is the same as “PROMISC” when running ifconfig).I wanted to learn this because when you use Reaver or Bully, you have to make sure that you are spoofing the actual hardware device as well as the virtual device (which is typically created using airmon-ng). I think you actually mention this in an earlier post.
So anyway, I am trying to write a little bash script which creates mon1 from wlan1, then each to the same new mac address This way I don’t have to execute 10 different shell commands before I start running reaver/bully.Anyway great job! What if ip fails to bring up your wireless device. Where may the problem lie?I’m using CentOs 6.5, with an Intel Pro Wireless 3945ABG. The iwl3945 driver is installed and loaded as module into the kernel.Here is the output when I follow your tutorial:$ iw devphy#0Interface wlan0ifindex 2wdev 0x1addr 00:18:de:30:d3:97type managed$ ip link show wlan02: wlan0: mtu 1500 qdisc mq state DOWN qlen 1000link/ether 00:18:de:30:d3:97 brd ff:ff:ff:ff:ff:ff# ip link set wlan0 up# ip link show wlan02: wlan0: mtu 1500 qdisc mq state DOWN qlen 1000link/ether 00:18:de:30:d3:97 brd ff:ff:ff:ff:ff:ff. In one of your many interesting presentations, you mention you also have an AWUS036H, and I hope you can help me with my connection issues for that antenna.While I am new to Linux in general, I recently installed the Kali Linux VMware on a host using Win7 x64. Once installed, I got everything (apt-get update, upgrade, and dist-upgrade), and performed many of the top 20 items you recommend. However, I am unable to get my antenna to connect, even using your recommendations in your article on wireless connections.When I attempt to connect my AWUS036H antenna in the VM, I get the following:“The device “Realtek RTL8187Wireless” was unable to connect to its ideal host controller.
An attempt will be made to connect this device to the best available host controller. This might result in undefined behavior for this device.”Some of my following commands, and their responses, are as follows::# ip link set wlan0 upRTNETLINK answers: Operation not possible due to RF-kill:# rfkill list all3: phy3: Wireless LANSoft blocked: noHard blocked: yes:# rfkill unblock allCan’t open RFKILL control device: No such file or directoryFrom the above, you may note I also installed the script you provided to change the user name at boot-up.This is more than frustrating, and I have researched every link I can find on the subject but no cigars. You are, in so many ways, my last option for a knowledgeable answer. Wow this is awesome.
Only it does not work for me even as the Gui tools do. Anyone else test this successfully on Kali 1.1? If I get time I will try it on a previous Kail release.Everything seems to work right up to turning the interface up w/ wpasupplicant where it never connects. My key and ssid are correct in the config file (confirmed with a separate calculation of the key).
Though I can bring the WLAN right up with the GUI. Using AWUS036NH adapter.Also failing on my Raspberry Pi 2 w/Kali 1.1 which is where I really need to get it to work for a class project.Any thoughts are welcome. I did a another 3 hour blitz at this and no joy. On my Kali 1.1 VM on my MBP I can’t get any WEP connection at all(using iwconfig). On the Raspberry Pi, I eventually got a connection that disconnected right away but it was inconsistent.
I forced the channel shown in AP config and now I consistently get connected, then disconnected with a deauth.wlan0: deauthenticating from xx:xx:xx:xx:xx:xx by local choice (Reason: 3=DEAUTHLEAVING)My gut tells me that something in both cases is interfering with the manual control. Like whatever makes it connect so easy in the GUI, is not allowing another process to control the WIFI. On the Pi it is probably a bug as there is no gui loaded in the base Pi Kali image.I fried on this one right nowneed to move to a different problemany thoughts would be welcome. Thanks for this great tutorial I am using a 2006 Toshiba A215 S7422 Satellite laptop which now has Linux Mint17.2 MATE runs as fast as it did when brand new in WinVista.
I have a home network I use the laptop for as all my other workstations, desktops and storage are ethernet cable connected. Nice to be able to roam around with wireless now and then here.

I use a Linksys E3000 router (simultaneous dual band ) i use “N” for both 2.4g and 5g bands. The laptop has a built in wifi as most did, but it is only ‘G: 54mbps which is slower than my cable internet. Great response.Conclusion: The MAC address of NO VALUE unless the router see the device.In my case the router does NOT see the device.
I monitored the Diag Log File and no request WITH THE MAC ADDRESS was initiated.My only access to the device is through an app on my mobile. The app should initiate the request but it does not.Since I managed once to actually see the router acknowledgment of the device and actually getting an IP; I can safely conclude that the device is NOT malfunctioning ( I have two of them)Another conclusion: by tweaking the router ( as you suggested) there is a chance that I can get a reliable “handshaking”.
Note: Be sure to change the NMCONTROLLED=”yes” to “ no” or the network service may complain about “Connection activation failed” when it cannot find an interface to start Switching to “network” serviceWhen the NetworkManager is disabled, the interface can be configured for use with the network service. Follow the steps below to configure and interface using network services.1. Set the IP address in the configuration file: /etc/sysconfig/network-scripts/ifcfg-eth0.

Set the NMCONTROLLED value to no and assign a static IP address in the file.
