When we returned home from vacation, our iPhones connected right up to our wireless, but they couldn’t load any websites. I was quite confused as nothing had changed with our wireless, but it failed to work; yet the computer worked just fine.

Turns out, the issue was with the DNS. A quick update to the wireless settings on our phone and everything worked again.

To fix your internet connection on iOS6:

1. Open Settings
2. Touch Wi-Fi
3. Touch the little blue arrow next to your active connection.
4. Touch DNS
5. Change the numbers to 8.8.8.8 (Google’s Public DNS)
6. Touch Wi-Fi at the top of the screen to return to the main Wi-Fi page.
7. Give it a few seconds and then try to load a webpage. It should work.

I don’t quite understand why the DNS just suddenly stopped working, but it was an easy fix and has been working smoothly since.
