    Hi, I have a few questions about wireless security. My Wi-fi router was always set to WEP and I was informed that I should use WPA2-AES as apparently there is software available to easily crack WEP.

    Now if someone had decided to crack into my network, would they have been able to see my internet traffic just as easily? I had network discovery off - would it have made a difference? I am very concerned about someone logging my online activity as I bank and shop online, not to mention other privacy issues. Wouldn't someone cracking a home network more likely want the bandwith than the information? (trying to put my mind at ease...)

    Use WPA2-AES and don't worry anymore. Your wireless adapter in your PC must support this type of encryption though.

    Yes if someone does get in, they can do anything their skill set allows them to do.

    Chances of anyone using software to crack your wireless encryption (of any kind) is very very low.

    If someone cracked your WEP key, then they can see your network traffic across the air. It is fairly easy to crack WEP, 10 mins is all it takes, or so I've read. However, when you are doing online banking or shopping, it is most likely that you are using SSL encryption,( the browser displays a lock symbol. ), so it is not easy to eavesdrop on the traffic. However, when that SSL is not being used, like when you use Hotmail, then they can view the traffic.

    Different routers use slightly different terminology, so I guess 'network discovery' means broadcasting your router name. Not broadcasting the name only hides the presence of your router from beginner hackers. Someone with the proper software can still see the traffic flowing thru the air when you are using the network.

    Hackers would hack your network for many reasons. Nowadays, they'd likely go for your computers, install keyloggers and try to get your banking IDs and passwords. They can sell those on the blackmarket, but they can't sell bandwidth :)
