I have a computer connected to the internet via a wireless router.
When i wanted to insert an aproved internet address i was prompt to fill a user name and password on my computer e.g the router is asking for usernamepassword in order to access the page.
I dont recalling ever resticting this action by user name and password.
How can determine these parameters?
The router usually has a default username and password out of the box.
Take a look at the manual (unually available on line)
If the password has been changed then you might have to do a hard reset on the router.
