OSX Yosemite Wifi issues

Oh no, sad to hear! How long did it last before the problem returned?

Me too. I am thinking of going back into the Apple store.

I've tried most of the fixes suggested in this thread but still no luck on my late 2012 Mac Mini.

I'm supposed to have a mid 2014 Macbook Pro Retina 15 delivered this afternoon and needless to say, I won't be upgrading to Yosemite until this get's ironed out. It's very frustrating but I'm sure Apple will roll out an update soon.

Not even close.

my mbpr 2012 got wifi drop everytime it comes back from sleep mode; need to manually discount wifi then reconnect it, stupid! my other mba 2013 just had no problem at all, still couldn't get any clues to solve this!

I have tried everything, but my wifi at home still works randomly. It's a WPA Personal 2,4ghz network. It works for about 30 secs before it stops. If I'm lucky, I can browse in Chrome for hours with no problems, but it stops working as soon as I open up App Store. Then I have to restart my MBP to get it working again (if I'm lucky...). Right now I'm at work with a WPA2 Personal 5ghz network and have no problems at all. Weird......

I upgraded to Yosemite on Saturday All other family mac books were still at Mavericks. My MacMini was upgraded, but it was connected to the network via Ethernet Cable.

Only my macbook pro retina (Late 2013) running on Wireless was affected.

Bluetooth has always been turned off. So that is not in conflict.

This morning, I checked my preferred network priority settings ...

System Preferences --> Network --> Wi-fi --> Advanced --> Preferred Networks

My Wireless network had shifted in priority below my iPhone and my iPad.

I selected my Wifi network dragged it to the top. Hit Ok then apply.

It has been two hours. I have not experienced any wireless network failure. Here is hoping.

Airport Extreme with both 2.5 and 5 GHz set up. Everything worked fine under Mavericks. Upgraded Macbook to Yosemite and I have the same Wifi problems as everyone else. Clear bug. The only thing that has worked 100% of the time for me, so far, is to assign a manual wifi IP address and use manual DNS instead of DHCP.

I only changed the wireless network mode of my router to "G-mode only" and now everything is back to normal.

Hope it helps.

i did that now by mac won't boot !! Stuck at apple logo with 20% percent progress bar completion !! Someone please help !!

I have the same problem.

I have a 10 months old MBP retina, and it worked fine until yesterday when I installed Yosemite, now my WiFi drops every other minute and its takes time for it to connect again.

Apparently apple support in Sweden answers this problem with "it has to be an error with your wireless card", which obviously is bull s**t.

This clearly happened to a lot of users since the installation of Yosemite, and is this problem getting fixed soon or do I need to uninstall Yosemite and install Mavericks again?

Your post is off topic. Please post in a new topic.

The only solution thats working now is that remove the password or encryption of the wifi and make it open wifi. Then it works without any problem.

Did that - worked for only about 24 hours.

Same problem here. Upgraded my macbook pro from Mavericks to Yosemite and since then, wifi connection is really bad. It connects to my wifi but seems like there is no traffic because websites takes too long to open or don't open at all. Apple, please FIX THIS NOW!!!.
