What Your iPhone is Trying to Tell You

You have three bars of Wi-Fi signal strength, but your browser won't budge and your apps won't fire. That means a bad connection is preventing information from getting from the Internet to your phone. If you've exhausted everything on the network's end?like asking the guy next to you in the coffee shop if his Internet is working?then start fresh.

One option is to forget the network. Hit the arrow next to the desired network name, tap Forget This Network, and then reconnect. If that doesn't work, do a hard reset (you'll hear this a lot) by holding the home and sleep buttons simultaneously for a few seconds. Then try again.

If you're using an older phone, the router could be the problem. One option: Go into the router's settings and find the section with the acronym WPA. Switch that to WEP. It's a less secure but more accessible security protocol that will let your older phone get on the network.

When all else fails, perform a broader reset. Go to Settings > General > Reset, and hit Reset Network Settings. Be warned: You'll lose all the stored passwords for all your networks. However, this will fix a majority of connectivity issues.
