WICD not detecting WLAN card.
 
Hi,

My ubuntu was working fine till morning but all of a sudden in the evening , its WICD manager stopped detecting my wlan card , because of this it couldn't detect any wireless network.

I formatted and installed the fresh copy, but the problem remains the same..

Interesting thing is that the same lan card works fine for Win7 OS.Even earlier in ubuntu it was working fine.
I have dual boot machine...

It seems that the Wlan-card is detected by the system, you should try to configure your wireless connection, probably the system has lost the authentication-data.

Can you just provide me some link so that i can just configure it..I am sorry to ask you this but I am new to this linux actually.

I am already searching on it. But if you have any link on mind.please inform me here.

Thanks.

But you wrote in your first post that wireless worked once with Ubuntu, you'll only have to do the same things as you die when you configured the wireless network for the first time. Take a look here: https://help.ubuntu.com/community/WifiDocs/WiFiHowTo

Thanks for the help...I will try it out and let you know.
And earlier I never configured wireless network , it already detected and worked fine.

Did you change anything with the configuration of your wireless accesspoint?

As you know, most wireless networks are encrypted and one has to configure the computer with the authentication-data before one can connect.

Well..I am a student of Vulnerability Assessment and Penetration Testing i.e. Cyber Security .
and few days ago we were trying things in our university lab and I may have change the configuration.
So I don't remember exactly. But We were doing the Wireless Security testing and all the stuff, so there is a possibility that i would have changed the configuration files.
And here I am facing problem with the wlan card detection..If the Wireless Lan card will be configured , it will automatically detect the wireless networks i guess...

If you want to list the available networks you can execute the command
Code:

iwlist wlan0 scanning
