how to find wireless password?

This is a password issue we can help with because you need to be cabled to a router to make major changes. Many routers have admin as the login name and password as the password so try those first. If this has been password protected beyond the manufacturer's default, you won't be able to get in. What make and model is this router?

There is a Sticky Post at the top of this sub-Forum headings page on how to change the wireless security key once you get in:- http://www.tomshardware.co.uk/forum/38111-43-find-change-wireless-security
