Ok I got a new router after I hooked it up right out of the box it was fine. I went to network pref on my macbook 10.5.6 and I tried setting up a WEP password under airport. I forgot where I went it said set up WEP and I put it in and then the internet went down. How do I get rid of it? I'm still new to macs. The router is a dlink dir-615. Can someone explain how I can fix it and set up a password for my wifi.
