Q: OSX Yosemite Wifi issues

I agree with the grand disappointment with apple.

My connection is now stable and functional, but it is SLOW, fwiw.

After 48 hours of my wireless network dropping I have a fix to the problem and is very simple, please update the firmware on your wireless router and that will fix all the wifi issue.

Today I just upgraded my rMBP 15 (mid 2014 version) to OS X yosemite and immediately Wifi is having intermittent connection problem. Apple, you dropped a big ball.

update the firmware on your wireless router

There is no firmware update for my router (and it's a little over a year old); and besides all the other devices on the network are just fine and so was the MBP before Yosemite. Something is broke in Apples update I'd think not the router.

I have the same exact problem. Help!

Same thing happened to me all the devices on the network are just fine and I even called Apple, was on the phone with them for 2hrs but tonight I decided to plug in the ethernet cable to my macbook pro and go into the brain of my wireless router and I updated the firmware and the problem was fixed

jalovette, maybe this will help. After trying numerous suggestions and having no success, I realized although I had looked at my system library preferences and everything looked normal, I hadn't checked my User Library Preferences in my Home folder. I've included an image of what I found,

You'll see there are numerous duplicates, and in some cases like Bluetooth, triple plists. Multiple plists cause system

conflicts since they almost always have different prefs, Your system simply doesn't know what you want to do, so it quits trying.

What I did was to delete all the prefs in my home folder, did a shutdown and restart. Then I shut down again this time doing

a PRAM reset on startup, and everything has worked well since then.  I had to reset my prefs for the plists deleted, so you might

want to write down which ones you're deleting so you know which ones you may need to reset if you choose to try this. I've been running all

day with no problems I'm aware of.  Internet is running like it did in Mavericks. Both system and user pref folders look normal.

If this still doesn't work out, as was my case, I read about this in a comment box at PC world. Someone suggested adjusting the Network preferences > Advanced> TCP/IP > Configure IPv6 > set it to local-only. Mine was in automatic and ever since I changed that and applied the settings, my wifi has been running smoothly, zero hiccups and ultra fast!

Hope this helps!!!

Same here, with mavericks I barely had any problems with the wifi, even with 2 of my ipads and my iphone I dont have any problems at all. It seems like it looses the connection for a while. When I restart the computer the wifi is great, as soon as I put my Macbook Pro 15" 2012 to sleep and open it up again the wifi seems to start having problems. It usually happens every 10 minutes that the wifi gets stuck and doesnt load anything at all. At first I thought it was a router problem, I checked it with, again, the 2 ipads and my iphone and there isnt a problem. I strongly believe its the new software Yosemite.

Other than this problem, I love the new looks of OSX

PS. The problem happens at my university too, which has (i believe) powerful routers and speed

With the upgrade my airport Utility no longer see my airport express. Another thing broken with Yosemite.

I've experienced same issue, but right now I can use wifi quite a bit longer than before. All you have to do is open the System Preferences, and leave it open. And you can enjoy your wifi for longer time without dropping off. Hope this help for someone who desperately need wifi. FYI the internet connection still slower than Mavericks. But this will do for me while waiting Apple to fix this issue.

Hi all,

I did most of the hacks posted in here, but they didn't do the trick for me.

What did thou was turning Bluetooth ON.

The moment I turned it on (while my WiFi was trying to reconnect for the nth time) WiFi got connected.

I really hope it will stay OK and maybe even fix the issue for some of you, cause it's more than frustrating.

Is it only me, or the last round of OS updates (iOS8.x and Yosemite) is a bit buggy? I made a clean install on both (iPhone 5S) and Macbook Pro Retina 13 late 2013 and I have issues on both. iOS crashes twice a day or maybe even more (settings, mail, etc) and on Yosemite I cannot even have a stable WIFI connection for a minute or two, disconnects every time. Besides that, the signal strength is also lower than on Maverics. If I had a "low" but still stable wifi connection on Maverics, now on Yosemite I can't even see the SSID.

I hope they push an update as soon as possible since it's almost impossible to do anything productive with a dropping connection every 30 seconds.
