OSX Yosemite Wifi issues

I for sure have this issue and it's very frustrating. Funny though, I could connect fine (it seemed) when using my non iPhone device at work for Internet sharing...seemed to keep the signal. But at home now, it kicks off after only a few seconds. I bet that the time it took me to type this, I got bumped off. Also, i notice, even when connected, the WiFi Looking for Networks notices still running...so it appears the PC is not understanding it is being connected. It appears. This is a major bummer!

I´m having problems with my macbook pro 13" late 2011. I did a fresh install.. it was all fine until....

Dropbox not connecting slow internet and it drops.. sometimes its connected but no internet... *** is going on..

I just tried something, which so far seems to be working. Go in to your Keychain access - System. Find your wireless network - double click. There are two tabs, Attributes & Access Control. Go into the Access Control and check "allow all applications to access this item". Mine was defaulted on confirm before allowing access, which I think was knocking me off every time I tried to do anything.

I'm not sure, but this is the first 10 minute period I haven't been knocked off since upgrading last night. Good luck!"

- Tried this, no change.

Having problems with wifi after installing Yosemite?

Yes and it is driving me crazy. I've tried all the reported fixes and nothing sticks. Not changing the location, keychain access, Kext, etc. It may seem like it is changing for a few minutes but it always comes back. And it is across all wifi connections.

I've been suffering from this same ailment since I upgraded on Thursday. After much gnashing of teeth (PRAM, SMC, reinstall of Yosemite, etc. etc.) I finally **RESOLVED** it by creating a new Network Location.

*under Network Preferences

*Click drop-down for Location

*Create a new location.. (I called mine "Internet")

*that's it!

hope it helps you too

Maybe I have stumbled across a compatibility issue?

- For me the problem is across all wireless networks

Here are the most prevalent solutions available:

1. Creating a New Wi-Fi Service (this solution worked for me!)
   • 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.
2. Delete and Reconnect to your Preferred Network

   Go into your Network Preferences > Advanced > Select Your WiFi Network and Delete It ( – ). Reconnect to it.

3. Delete Bluetooth.plist

   Finder > Go (on your toolbar) > Computer > HD > Library > Preferences > Delete your Bluetooth.plist. Reboot.

4. Delete SystemConfiguration

   Finder > Go (on your toolbar) > Computer > HD > Library > Preferences > Delete your SystemConfiguration. Reboot.

5. Reset PRAM

   Reset your PRAM (Haven't tried it myself so I don't feel right instructing others how to do it, sorry!).

Sorry if this isn't as comprehensive or clear as you may need. If you need more clarification, I'll keep this thread open and check periodically.

Good luck!

I've tried all the solutions Nickish mentioned, multiple times because they are so often mentioned.

Some of them seem to work for a short period of time and then the problem returns. Also - these are the same fixes that were often mentioned for Mavericks. I had a wifi problem with Mavericks and the change network location worked. On Yosemite no such luck.

Hii

I haveiMac late 2013 with fresh Yosemite, Time capsule 2013, iPad mini is, I had issues with apple TV stutter (ATV 2), I just restarted the time machine. Its ok now

nice day

Same issue. Tried everything, delete SystemConfiguration, remove/add Network Locations, change kext, disable WPA/WPA2 security, change router, change 5Hz to 2.4Hz, all this things. Usually it works for 5-10 minutes and then goes down to 0,5 mbps again. ALL betas works fine but final release.

Clean install. No changes.

One month ago I fu***ed my brain with 'awesome new' iOS 8.0.1 update, and now, I'm f***ing with NO internet and have NO work with 'most advanced operating system' that just doesn't work on the top level Macbook Pro 15'

Apple, what's wrong with you?

I'm just tired. I need to finish my work and I can't.

'Buggy than buggy'.

I resolved the WiFi problem by creating a new WiFi Service but I can't use apple applications, they don't connect to the internet, Google Chrome Does, but not safari, iTunes, FaceTime, etc.

Also can't connect to iCloud...

Very frustrated I wish I didn't udpate to Yosemite...

Also tried all the suggested fixes and still getting kicked off after 5-10 seconds. Another botched launch and the silence from Apple is ridiculous.

hi, i did a clean install of yosemite on my macbook pro retina 13inch early 2013, my 2.4ghz wifi is working perfect but when i connect to 5ghz wifi, everything gets extremely slow, i can hardly open any website, it is totally frustrating because i was using 5ghz wifi perfectly on mavericks. 2.4ghz is so crowded here, i have tried all the solutions. i hope apple brings a update soon to fix the issue. my router is ASUS AC-RT87U with upgraded firmware. seems like a compatibility issue. 😟

With bluetooth on I get about 1-2MBps the second I turn bluetooth off I get 100Mbps on WiFi - turn bluetooth on 1-2Mbps again.

I have Wifi issue too after upgrading to Yosemite. It was working good in Maverick.

Pings to any website works good. But wifi stops working every 2 minute. This i Frustrating.

I don't know Why apple started releasing product without checking ?

I have Macbook Pro 13" (Mid June 2012)
