OSX Yosemite Wifi issues

I solved my problems with WIFI speed after disabling Handhoff between ICloud devices (General panel of System preferences)

Launch Terminal (you can get to it via the Spotlight icon at the top right. Copy and paste these lines below.

Enter:

sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist

(and hit return and enter your account password)

Now enter:

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist

(and hit return)

Now check Safari.

My brother just had this problem on a Mac that has been upgraded and upgraded time and time again. None of the other fix suggestions worked.

I saw this problem on my older Mac with the Yosemite betas. discoverd is the new name resolver process and it seems it's still buggy.

Apparently you will be stuck running this command every reboot/switch-on or every time discoveryd craps out.

Other with issues with wifi. I have MBP Retina 15" (Late 2013), and i have to disconnect and connect because surfing is impossible. I never had problems in Mavericks, and other devices like Iphone 6, iPad Mini works.

I installed Yosemite clean install with a USB.

I'm having the same WiFi issues that others have reported. It wouldn't accept my Apple ID on the setup screen following the installation (error: couldn't connect to the server), which I had to skip, and upon reaching the desktop I can't access the internet at all even though it says I'm connected. ASUS RT-AC87U on the 5Ghz band. Selecting the 2.4Ghz band allowed me to download the first update but when it got to the installing stage it gave me an error saying the download failed. It successfully went through a second time. Very frustrating. Never had a problem with previous versions of OS X.

Late 2012 Mac Mini

I have the exactly same problem. Internet just works for 5 seconds at least. I have to use the wire internet and I had no problems with Mavericks. Any solution? this is really annoying!

I think something is definitely going on with the router/Yosemite connection because my ASUS router is brand new and I never had issues until I updated to Yosemite yesterday. I tried using my phone as a personal hotspot and have no issues with keeping the wifi signal and everything loads normally like it should. But, when I turn that off and try to go back to my wireless connection via the router, the signal does not last. It loads pages slowly, if it even decides to load. I tried all the troubleshooting options everyone in this thread has listed but nothing seems to work at all. Apple needs to get it together and fix this because I can see that a lot of other people with this same issue are college students as well and I can't do my online classes with the wifi connection I'm currently getting.

I was having the same wifi problem after upgrading. Today i did a clean install and now my wifi is working just fine.

I'm having the same problem since the update. Until they (or if they) release a fix, click on the wifi icon in the taskbar when it goes out. Choose 'Turn Wi-fi Off'. Then click on the icon again and click on 'Turn Wi-Fi On' and it comes back. It's a MAJOR pain!

@mamaricci: great idea, but didn't work for me.

I doubt this has much to do with the issue, but I can switch to a different 5Ghz access point, and connection is fine... for a little while. Then it starts all over again.

I'm having sort of a similar issue, seems like it's a bug with Yosimite. I can connect to my home wifi just fine, but after 10 minutes or so it just disconnects by itself. Never had that problem before on Maverick. Apple will probably address it in its next update.

Same issue on mine. Brand new ASUS AC router, worked fine on Mavericks, now works like crap for all of our Mac devices. Tried removing the old keychain system wifi logins, but keychain continuously crashes if I try to edit it now. Not so impressed with Yosemite thus far. iOS failures on roll out are equally depressing. Hoping Apple is fixing both very soon - this is almost as bad as a Windows roll out.

This is really unlike Apple. But I'm sure they're already aware of the issue and trying to find a fix. Also, I notice that mine mostly disconnect when I'm watching videos on YouTube or streaming things. If I just use it normally, but it happens less frequently.

same problem here. no internet connection for any apple apps. chrome work fine

looks like the same issue may users have with their ipad when switching to ios8... Like me. Apple stille didn't solve this issue. So i'm gonna wait this time with upgrading my macbook air to yosemite. One faulty apple device is enough for me.

By the moment, fixed turn of Bluetooth.
