Updated to iOS 6 but ran into WiFi problems? Here’s an easy fix.

A lot of iPhone and iPad users who updated to iOS 6 have been reporting that the update made their iPhone and iPad’s Wi-Fi grayed out.
Based on reports, the issue has arisen from a network verification process embedded within the software, whereby the iOS attempts to load a dummy page on Apple.com to detect if users are connected to a paywalled network. Unfortunately, the verification page seems lead to a 404 error, resulting in an inability to connect to Wi-Fi.
Although this issue is not affecting everyone, but it’s worth attempting the fix below:
Go to Settings > WLAN > (“Your Network”) > [the blue circle arrow icon] > Scroll down and set HTTP Proxy to Auto
You might also want to try to Reset Network Settings:
Settings > General > Reset > Reset Network Settings
Perhaps this is just a temporary glitch at Apple or are we expecting a software fix soon?





might be a good fix,
except people are unable to select these when there wifi is greyed out…
A hard reset worked for me. Press and hold the top and bottom buttons at the same time till the phone shuts off.
