One peculiar issue I have run into in the past was when a Mac would freeze when a user would try to join it to their company’s internal Wi-Fi network. After trying different things for some time, I decided to do a little research.
I discovered that there were cases that Mac’s would freeze when connected to certain networks via Wi-Fi. What could be causing such an odd behavior? The answer is IPv6. Mac’s don’t always play nice with IPv6. Thankfully there is an easy fix, though it does need the use of the Terminal (Located under Utilities, which is in of itself located under Applications in the Finder).
Inside the terminal, simply run this command to disable IPv6 (Note: Only applies to OSX 10.7.x and up):
Networksetup -setv6off Wi-Fi
To re-enable IPv6, run this command:
Networksetup -setv6automatic Wi-Fi
