All of a sudden my machine's wireless network is not connecting to my WiFi router.
How can I figure out if its an issue with the WLAN card or if its withing the Ubuntu system settings ?
Is there a command to check if the wireless is working ?

$ nm-tool
NetworkManager Tool

Yes, Broadcom STA wireless driver is activated. I haven't changed anything pertaining to IP config. Where to find that option? I couldn't find it. No, I did not dual boot it. Yes, wireless switch is 'on'. –  Saikiran Apr 11 at 13:39

Are you sure Proprietary Drivers are enabled?

Are you sure you have not made any edits in the IP configs? Set it to "Automatic (DHCP)".

Do you have Windows installed? Does Wireless work in Windows?

Are you sure your hardware switch for the Wireless Card is turned on (this feature may not be present in some computers) ?
