Hi.. is there some sort of a GUI that shows the available wireless networks in the area? Reason I ask is I have a few networks at my workplace and they have varying signal strengths.. so I need to often switch my wireless ESSID based on where I am and how strong each signal is.. any tool that can make this process easier? (other than running ifconfig/iwconfig).. it's also useful when one goes to a new area and is looking around for a network.. Thanks, nirmal
