Router password or wireless key?
router key -
go to the manufacturers web site and find the default ID and key. Then use the reset method from my prior posting. Then change the ID/password and wireless key - write it down and tape it to the bottom of the router.
Wireless key - If you have a working device (ie Windows PC) then download this program to display the key.

otherwise reset the router and change the password and key as above.
Good Luck
When it asked what I wanted to do when downloading, I chose "open" rather than the other choice, which was "save". Could it have been that?
