I can't connect to Wi-Fi. What do I do?

If you have trouble accessing a Wi-Fi network, one of these tips may help solve the problem:

• Make sure Wi-Fi is turned on: Open Settings, tap on Wi-Fi (upper left, below Airplane Mode), and swipe the Wi-Fi switch to ON.
• Turn off Airplane Mode: When turned on, Airplane Mode disables the wireless features on your device. If it's turned on, you'll see a little airplane icon in the top left corner of the screen. To turn it off, open Settings and swipe the Airplane Mode switch in the top left of the screen to the OFF position.
• Check the Wi-Fi connection: Occasionally, your device will disconnect from a nearby Wi-Fi node for no apparent reason. Open Settings and look at Wi-Fi in the upper left corner of the screen. If the words "Not Connected" are visible, tap on Wi-Fi and select the desired network in the Choose a Network section.
• Restore your settings: Described earlier in this section, this erases all the saved network data and can sometimes solve connection problems.
• Reconnect to network: Disconnecting and then reconnecting to the desired Wi-Fi network sometimes solves connection problems. Go to Settings, Wi-Fi, tap on the blue arrow to the right of the Wi-Fi network in question, and tap on the Forget this Network button. When your iOS device rediscovers the network, try reconnecting.
• Eliminate interference from other wireless devices: Sometimes, cordless phones and other wireless devices can interfere with the Wi-Fi signal. Turn them off or move them away from your iOS device or Wi-Fi access point.
• Check your range: The useful range of a Wi-Fi access point varies, depending upon the version of Wi-Fi being used (802.11a is about 1/3 of 802.11b/g) and the construction of the building you're using it in (brick walls and metal frames reduce range). If you're encountering weak signals, move closer to the access point or install multiple access points throughout your building. In addition, you can find wireless range extenders for sale online. Prices range from $50 to $200.
• Reset your router: If nothing else works, you can try resetting your access point to its factory settings. Check the user manual that came with the access point on how to do this. Be aware that you will have to set up your network again.
