OSX Yosemite Wifi issues

Hi there,


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.


Tethering to my iPhone seems to work ok, as does using my home network via wired ethernet.


Are any others having problems with Yosemite? Wifi was working fine on Mavericks.

Thought I was the only one but turns out others are having this issue as well.

What bothers me is that for example YouTube doesn't even work. First it starts buffering on 480p then turns back to 144p and even that won't load. Tried this on Safari and Chrome and both problematic.

I'm on a 5Ghz network but my 2.4Ghz network doesn't work either. How can this be so hard to solve? I remember having this issue too when Mavericks just came out.

I am currently, after updating to Yosemite experiencing the same unresolved issues regarding wifi connectivity. Initially it works, after a certain amount of time wifi speed drops to the point of being unusable.

Unfortunately I do not have a solution. No reaction whatsoever on apples side either - wondering if they even have a support team.


...and its not only Yosemite, iOS 8 is also ridiculously buggy (bluetooth/car itunes/sync).


I really do understand why microsoft encounters so many software problems, given that they have to deal with endless amounts of hardware. Apple has no such excuse. I am disappointed, to say the least.

I tried everything and this worked for me!


Thanks to whoever found this fix.


  • Copy and paste these instructions, because you'll be disconnected from the Internet and you'll need to reboot.
  • Go into your Network Preferences > Select Wi-Fi Service (in the list in the left column) > Click on the options (cog icon) > Select "Make Service Inactive" > Select Apply.
  • Select the same Wi-Fi Service > Delete It ( – ). Reboot.
  • Return to Network Preferences > Create a New Service ( + ).
  • Inside the prompt select Wi-Fi under Interface, name the Service Name something other than Wi-Fi. (I named mine Wi-Fi2. Apparently if you retain the previous Wi-Fi name the WiFi dropping will return on reboot.) > Click Create.
  • Click Apply.

I have a Macbook Pro (2012). After upgrading to Yosemite, wifi began dropping every 15 minutes or so. I chatted with Apple support about this. They emailed and told me to try "Resetting the System Management Controller (SMC)." Instructions found here: Intel-based Macs: Resetting the System Management Controller (SMC) I reset as instructed. It did not solve the problem. My wifi keeps dropping. It just dropped out again, as I type this. Ugh.

Update on this post. After more time with it, this solution did NOT fix the problem. it continues to drop WIFI. Ethernet continues to hold connection. Bluetooth off vs on definitely seems to play a role here.


Question for those who suggest deleting your WIFI connection and building a new interface (e.g. WIFI2), does deleting the wifi interface remove all of the remembered wifi networks?

Hi there, I´ve just had a nice chat with Apple Support in Norway and he solved this for me, thank god. And the best part is that it´s so easy to fix!


Follow these steps:

Open System Preferences

Click on Network

Select Wi-Fi in the left panel

Click on the Advanced button (bottom right in the same window)

In this next window you have a list of your preferred networks, delete every network you don´t use by a regular basis. I think I deleted at least 20 networks from shopping centres, airports, hotels etc.

Click Ok.

Voilà!


Hope this does the magic for others as well. Good luck!
