How do you find a WEP key, when the browser wont bring up the site http:\\192.168.1.1?

If all else fails, do a hard reset on the router and start over. "Hard reset" is not just a power cycle... there is usually reset button on the bottom or somewhere that requires a stylus (pen, paperclip, etc.) to push it... you usually have to hold it in for 30 seconds or more to cause the hard reset. This will take your router back to factory default settings for everything.
