Mac Mini Dropping WiFi
I have a Mac Mini (Mid 2011) and recently it began dropping wifi. This started about two months ago, and I think it may be related to a firmware update because prior to that it had no problem. Initially, it seemed to drop wifi when the unit went into screensaver mode or when I put it into sleep. No it seems to do it whenever I'm idle. I've checked and double checked all of the settings, and I cannot find a setting with the option to power off the wifi when during sleep mode or when the screen saver turns on, etc.
I have a Mac Pro (Mid 2012) and it doesn't seem to have this problem. I also have a MacBookPro (Mid 2012) and I also haven't seen a problem with that either. We have two PCs on the network, but none of them exhibit this problem.
It may seem like a small thing, but sometimes it can take in upwards of 10 minutes for the Mac Mini to establish a connection. Any ideas?
