Hey everybody! 
So I've been having a strange issue with this wireless network. My roommate has a wireless router. I have been trying to connect to it, but without any luck. I typed in the password correctly...I've checked it many times. It seems like it wants to connect, but it just stops at "Alert: No Internet Connection" and it shows a little exclamation mark where it monitors the WiFi signal strength. What's weird, though, is when I plug it into the EtherNet in, the exclamation mark goes away and it shows supposedly full WiFi strength. It goes back to the exclamation mark if I take the EtherNet cable out. Two other computers can connect to the WiFi perfectly while my computer can't. My computer is running OS X 10.7.4. Does anybody have any clue what I can try doing to make my computer connect? Many thanks!
