The Apple eco-system – iOS devices and OSX systems – seems to have a few problems with wi-fi connections, especially in the time just after upgrades. I have experienced this myself a couple of times, as I documented here on my blog.

Recently, I found a page on Apple’s Support site, which details Apple’s Recommended Wi-fi settings for iOS and OSX.

Below I’ve outlined the main recommendations:

  • SSID – Any unique name
  • Hidden Network – disabled
  • MAC Address authentication or filtering – Disabled
  • Security – WPA2 Personal (AES)
  • Channel – Auto

I’d suggest checking the page on Apple’s Support site in full before making any changes to your wi-fi setups.

Note: Changing the security to WPA2 recently fixed my Wi-fi problems after the OSX upgrade to Mountain Lion.
