Hey guys. I have a question/problem regarding using the wireless internet on my MacBook. Since I got my MacBook, my sister hooked up the computer though LinkSystem, since that is the only option we have at the house. We have Cable internet with a Wireless-G BroadBand Router that helps the downstairs computer link up the the internet. Well today, we had the power shut off in the house because we are getting a few rooms painted with new electrical outlets put in. I went to on my MacBook today and I found there was no internet connection. So I went under and clicked on Linksystem but now it asks me to give them a password to connect. I dont know a password and my sister can't remember if she did or did not put one in to connect. Please help me!
