How do I increase wi if security on my Wi-Fi setting. It is suggested I change a setting on my at&t router. I do not know how to do that.
The directions to change the settings should be included in the router's manual. If you don't have the manual, you can Google your router's make and model to find directions on the internet. If your router is included with your ISP's modem, you should contact them. Perhaps a new modem will do the trick. Apple's recommendations are in the blue link above your name on this page.
