Enable WPA Wireless access point in Ubuntu

Sponsored Link
I have a Thoshiba laptop at home, I was running “Edgy Eft” (Ubuntu Linux 6.10) But one of the important things about it was its inability to connect to WPA-encrypted Wifi access points.In my home i have a WPA Enabled Wireless router so i need to connect to my wireless network using WPA.I am giving the procedure that worked for me to enable wpa in my toshiba laptop.

Procedure to enable WPA Wireless in Ubuntu

To update the source list run the following command

sudo apt-get

sudo apt-get install wpasupplicant

sudo apt-get install network-manager-gnome network-manager

sudo gedit /etc/network/interfaces

Comment out everything other than “lo” entries in that file and save the file

Create a file called /etc/default/wpasupplicant, add entry ENABLED=0 and save the file

sudo touch /etc/default/wpasupplicant

Reboot your system or use the following command

sudo /etc/init.d/dbus restart

Once you login back in to your machine you need to left-click the network manager icon in Gnome and select your wireless network It should prompts for password, type, etc and It will ask you to choose a password for your new “keyring”.

After enterring all the details my wireless network was connected and working fine you can see in the follwoing screen

My wireless network also detected available wireless access point around my home you can see this in the following screen

If you want to connect an existing wireless point you can see the following popup box asking for details of wireless network

If you want to create a new wireless network you can see the following screen with the available options and after entering all the details you need to click on connect

    Stuck the same as Fmpfmpf, and several others: all went well but then no wireless option in Network Manager and no wireless strength icon on the menubar. :/

    Well, my notebook is a Toshiba Tecra A4. When I installed Hardy (8.04) couldn’t config neither wired interface (Marvell) nor wireless (IPW2200BG). With Intrepid Ibex (8.10) I got wired interface, but I still have problems to connect WPA wireless connection. My iw interface detects 4 access points, but gnome-network-manager didn’t give me a WPA option.

    Oosh!! It worked when I configured it using Networkmanager, by DBUS & HAL.

    Thank you for the tutorial. I’ve made some great headway with this when I couldn’t find any other information online!

    I have a problem, though. After all the steps, I don’t see the WPA option unless I create a network in Network manager with the SSID of my wireless. If I follow the tutorial steps and try to connect with the router, I don’t see the WPA option. I can’t connect to the network and my password doesn’t save.

    I am using a Toshiba with a Wi-Fi card that should be able to use WPA. I’m also running Ibex.

    RedBob, could you explain what you did to get this to work? Any help would be awesome!
