Apple’s release of Mac OS X 10.10.1, which was intended to — among other things — improve Wi-Fi reliability, hasn’t completely resolved the issue.
On Apple’s Support Communities, there are still complaints of dropped connections and slow speeds on Macs that were updated to Mac OS X Yosemite. In fact, “ComputerWorld” (http://tinyurl.com/q2fsysm) notes one support thread that contains more than 1,100 posts. Here are a couple of the complaints:
“I upgraded my Macbook Pro Retina 15″ (mid 2014 revision) to OS X Yosemite last night and am now having issues when using my home WiFi connection. Whilst it connects to either the 5Ghz or 2.4Ghz network, it is basically unusable. Web pages take minutes to load (if they even load at all), dropbox doesn’t sync because it can’t get a connection and even trying to get to the router config page is extremely slow and hit/miss.”
“The same has happened to me. Never had a problem with Maverick. Making it impossible to do anything more than about 2-3 minutes before wifi is dropped.”
