Not fond of the recent OSX 10.10.1 update, supposed to improve wifi reliability. Not that I had any problems with my two MacBook Pro’s. Not at all. I simply upgraded, and started having trouble with my old mid 2011 (rev 8,1) edition. Looks like I’m not alone.
Symptoms: wifi disconnects randomly after a few minutes. I deleted the network, rebooted like if I was running MS Windows, then joined the network again: it didn’t help. (…)
