iOS Tip 104 - Watch Out for WiFi Assist

Way, way at the bottom of the Cellular Data settings on your iPhone or cellular iPad is a check box for wifi-assist. If this box is active, your iPhone will use cellular data whenever you have a spotty wifi signal. While this could be handy and not cost you much if you have an unlimited data plan with your cell carrier, if you do not have unlimited data you could suddenly find yourself eating through your data plan.

If you are not on an unlimited data plan consider de-activate wifi-assist unless you really need it and then only turn it on temporarily. Go to Settings > Cellular and scroll to the very bottom of the screen to toggle On or Off.

iPad Tip 27 - Connectivity: WiFi Security

Since the release of the iPad, many iPad owners have been experiencing WiFi connectivity issues, especially to networks that use WEP security. Since many routers and access points (such as the Sprint OverDrive mobile hotspot), use WEP security by default, it poses a problem for access on the iPad.

If you are having problems connecting your iPad to your OverDrive or other router via WiFi, you might want to check your router settings and select WPA/WPA2 as the security protocol.
