How do I sync my iPhone to my Actiontec modem?

Turn on the wireless on the phone, search for your home WiFo connection, enter the encryption key, then surf all you want.

Some modems have a wireless on/off switch. Make sure the wireless is on.
Make sure the wireless light on the front of the modem is on.

Also log into the router to make sure the SSID is being broadcasted.
The modem's address should be http://192.168.0.1
OR
http://192.168.1.1

Username should be admin and password is blank.

Hope this helps.
