Crap well now I've discovered I already knew the WEP but now I don't know why it isn't working.
I have a computer on my upstairs that is connected to the internet with a 2Wire modem/router. I have a computer on my downstairs with no internet but it isn't connecting to it with the Netgear adapter I have plugged in. It has a signal from the upstairs but it still says it has no to little internet connection.
I have a big feeling that one reason it that the 2Wire modem downstairs doesn't appear to be on. It's plugged in but I have no green lights or even red lights for that matter. It's as if it has no power at all.
EDIT:
I tried replacing the AC Adapter from the downstairs with the upstairs computer and it worked so the power problem was the downstairs adapter. I tried replacing it with a universal adapter and it stayed green for about 5 seconds then went back to red so that didn't work. I'm going to return the universal one and hopefully find a working AC Adapter. Afterwards if it works I'll see if any more help is necessary. Thanks.
