You probably should just cancel your credit card and have them issue a new one and then open up new account in your name with the new card you get. Rich

set the ip address to be detected automatically in the tv network settings.
What you need to know is the encryption key used on the Wi Fi
If you do not know it it might be on the case of the Wi Fi access point device.
Otherwise you will need to log into the router by typing the router's ip address into an internet browser on the working computer.
