Wireless internet problem.


I’m on an ethernet cable to my cousin’s wireless router. It’s a D-link DIR-615. It says that it’s an open network availble to all users, but when I try to connect wirelessly, it asks me for a security password, I typed in the password on the back of the router, and it didn’t let me in, so I went to manage wireless network and security and it said

Security type: no authentication (open)
encryption type: wep

and it gives me the network security key when I click show characters.

So I copy past the security key when I try to freaking log into the wireless it says I have limited connectivity and I can’t connect to the internet. What exactly am I doing wrong?
