Q: Yosemite (OS X 10.10) killed my WiFi :(

I just updated to Yosemite on a brand new 15" MBP Retina Display. For some reason my WiFi is not working. I turn it on and select the network I want to join (my regular network at home that I've been using with this same computer before updating). So, I turn it on and select the network and doesn't seem to want to join it and then my WiFi switches back off completely.

 

Is anyone else having problems with their WiFi on Yosemite?

MacBook Pro (Retina, 15-inch, Mid 2014), OS X Yosemite (10.10)

    Thank you!  This worked perfectly.  It was so irritating to buy a new Macbook Air 2015 and have to see the WiFi status icon showing no connection when, in fact, it was connected.

    I tried every solution on this thread and most helped for a minute. Installing 10.10.3 took a day and it made light usage of wifi possible. But when for example downloading updates from internet, whole network started laggin (every machine in network). If I manually downloaded stuff with my older laptop, everything was good, so culprit is yosemite, not network.

     

    So IMO yosemite is total lemon. A rotten apple.

     

    Machine iMac 14,1. WIFI: WPA personal (2,4 GHz).

     

    My solution to get a usable Mac: Downgrade to maverick.

    Can you supply a link to this fix? Also same for 7times7. I've gone back a few pages and cannot find these "solutions".

     

    I do have the wi-fi problem on my MBP but not on my iMac 27. There is no problem on three iPhones, two iPads or two ATVs. It is pointless people saying they have a fix after connecting for 15 minutes or even hours. My MBP can stay connected all day but then it loses it again. I may be wrong but this appears to be related to waking from sleep. i.e. the connection is not there when I start up in the morning, either after being powered off all night or just asleep. Also, it reappears when I again wake from sleep in the afternoon or evening. Once connected, which may take several attempts, it seems to remain connected for hours.

     

    Other problems, probably related to Yosemite, are: occasional automatic restarts (these have been quite recent but it has not occurred for several days now). Problem connecting an external LaCie 1TB portable drive. In the past it has occasionally connected but then gets reported as being disconnected incorrectly when it has never been touched. It works perfectly well with the iMac. This has been reported in a different thread.

     

    As with kkuja, I have tried one or two reported fixes with no joy.

     

    Finally, I am not sure how people can report a "slow" connection, or one that is slower than normal. We live in the countryside and the internet is never great (forget those BT adverts about Infinity and Netflix will never make it). I have to explain this to my son who screams at his PS4 when it grinds to a halt and he apparently loses his FIFA match with his mates. It seems to revolve around the time when people come home from work or school and switch on to our village's limited supply.

     

    I am simply waiting for an Apple fix which will no doubt arrive in the goodness of time - trying as it may be.

     

    Cheers

     

    TY

    This helped me. Have tried about 5 other things, but this was it.  Thanks for sharing.

    Baaaaaaaa

     

    I tried everything... eeeeverything.

     

    AND IT WAS THE ROUTER!!!! I Put it in WLAN BASIC SETTING "ONLY N" !!!

    OMG....

     

    IEEE 802.11n ONLY

     

    bam!!! Works. With normal location, nothing delete (prefs..) or anything. Just normal location, with all services active (Ethernet, firewire, BT...)

     

    I have Macbook pro 3.1 15" (Core2duo), 4 gb ram and SSD running 10.11 El Capitan.
