Good

Never an issue on my iMac, but I do love updates. Curious thing is this IS an issue on my 2011 Macbook Pro. Minor inconvenience if anything. Going back to the fact that I do LOVE updates.

I have this issue with my Fall 2010 11" MBA. When I open the lid from sleep sometimes the wifi won't connect or will connect to another network. I hope this issue is addressed for my model as well.

Well, this would be useful if I hadn't long since given up on wireless with the iMac and hooked up an ethernet cable.

It fixes it! Finally! I thought it was something on just my system. It also fixes finding wi-fi on reboot as well. No more manually trying to get on a wi-fi network that takes up to 30 seconds after waking from sleep. Now it is automatically reconnecting to my wi-fi network and loading a web page within 5 seconds of wake up.
