Yesterday’s dot-release of OS X 10.10.1 has seemingly failed to address the WiFi problems some users have been experiencing since upgrading to Yosemite, according to continuing posts on the Apple Support Communities.

ComputerWorld quoted a number of illustrative complaints from a support thread containing more than 1,100 posts.

10.10.01 does NOT fix the Wi-Fi issues. I had to go thru the same extreme routines I have had to go thru the past 2 months to be able to connect to the Internet.
Apple has made no official statement on the problem, though several forum members report that Apple Care has advised going into System Preferences > Network > Advanced and removing old entries from the preferred network list, as well as performing an SMC reset.

Early stats from Chitika suggested that Yosemite adoption speeds have been slightly faster than those for Mavericks.
