   iOS 6.0.2 Squashes Unspecified Wi-Fi Bug

   Agen G. N. Schmitz

   Released with a typically perfunctory description, Apple has pushed out
   [1]iOS 6.0.2 for the iPhone 5 and iPad mini to fix 'a bug that could
   impact Wi-Fi.' With such a blank slate to divine from, our first guess
   was that this could be related to the excessive cellular data usage
   problem that's been documented in several articles here at TidBITS '
   including Matt Neuburg's '[2]Mysterious iOS 6 Cellular Data Usage: A
   Deeper Look' (24 October 2012) and Glenn Fleishman's '[3]What's Behind
   Mysterious Cellular Data Usage in iOS 6?' (29 September 2012).

   However, Adam Engst came across a couple of discussion threads at Apple
   Support Communities that suggest this fix is meant to patch a problem
   with the iPhone 5 that either [4]disabled Wi-Fi completely or gave the
   appearance of a connection to a Wi-Fi network yet [5]received no data
   over Wi-Fi.

   If you've got workable Wi-Fi connectivity, we recommend going the
   over-the-air update route (go to Settings > General > Software Update
   on the device) as this method downloads only the deltas and are much
   smaller and faster to install (a 51.4 MB download for the iPhone 5 and
   a 32.9 MB download for the iPad mini). You can also grab the full image
   of iOS 6.0.2 through iTunes on your Mac (which downloads at a heftier
   819 MB).
