easy WPA on linux lubuntu/ubuntu/debian with GUI User Interface - easy way to use wpa without bad password problem

easy WPA on linux lubuntu/ubuntu/debian with GUI User Interface - easy way to use wpa without bad password problem

For example on Lubuntu we have the network manager that is not acting like expected and the same goes for wpa supplicant (see below)

wpa supplicant installation (NOT SUGGESTED)
wpa supplicant can be installed with those simple commands

$ sudo apt-get install wpasupplicant
and (if you want the gui)
$ sudo apt-get install wpagui

with the main problem is that wpagui doesn't recognize several wifi cards even if available from iwconfig (just read other tutorials if you don't even have the wifi network card shown via iwconfig).

As example this card doesn't show up with wpagui (on lubuntu 11):

description: Wireless interface
product: PRO/Wireless 2200BG [Calexico2] Network Connection
vendor: Intel Corporation

Fast Solution: 
Just install Wicd by using:
$ sudo apt-get install wicd


If you are still unable to use the wifi (with wpa) connection by getting errors regarding the authorization or bad password (if you are really sure that you are setting the correct password) with wicd on ubuntu/lubuntu just restart the service or reboot.

example:
$ sudo service wicd restart



________________________

Wicd DNS problems are not really problems

If you still have problems with the name resolutions just configure the preferences (global dns servers) of wicd with generic (or your own) DNS servers

example: 8.8.8.8    8.8.4.4  (google dns)

They can be also set for each specific wifi netwok.
