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)

    OK I will try because it is not so easy for me due to my English ( I'm French ).

    I've tested Beta of Yosemite because after changing my iMac ( With Maverick ) in May, I had many problems ( always the spinned wheel  which appeared sometimes and I' didn't know why) I never had this with my previous iMac.

    All has been done ( also with the help of Apple hot line ) and I always had occasionally this multicolored wheel which stopped all my iMac but not the Mouse !! Why, I don't know.

    Following this problem, I've decided to update my new iMac with Yosemite beta just before the official version.

    And.... the problem was always there!!

    This morning, I've seen on my APP STORE a proposition to update Yosemite with 10.10.1... Nothing to loose, I've decided to make the update and since this morning, all is perfect ( I hope !!) no freezes , no blockage, internet is more fluid and faster ( What Apple has done, I don't know but it seems a good modification for me ). The file Updated was 350 Mo size.

    Hi All,

     

    With some of the early reports of the 10.10.1 beta resolving 5 GHz connection issues I decided to install.  I can report that the 10.10.1 beta did NOT resolve my 5 GHz connection problems.  In fact, where with 10.10 I could occasionally connect to the 5 GHz band, I am not unable to connect at all.

     

    The 10.10.1 Beta did not resolve my 5 GHz connection issues.  In fact, it may have made them worse.  For the mean time, I am using only my 2.4 GHz band.

     

    Cheers,

    Hi Don,

     

    Why do you separate the broadcasts? Your machine should pick the best signal and run with it. I've never lost speeds, transfer rates etc. Are you using a AE or TC? I have a TC and found that. Obviously, if you have neither then I've just wasted you life reading this!  

     

    Whilst it doesn't help you at this moment in time, I separated my 5GHz, connected, without any issues.

     

    Maybe a reset of the router might help?

    Hi Tim,

     

    I am sorry but I do not understand what you mean by "separate broadcasts" or the difference between "AE or TC".  I have done all of the common things suggested in this thread including rebooting the router.  Nothing has improved my 5 GHz connectivity issues.

     

    Cheers,

    Don,

     

    Sorry. AE (Airport Express) TC (Time Capsule). On my Time Capsule, it can broadcast both 2.4 and 5 GHz at the same time. You can specially ask it to separate out the broadcasts so you see "your wireless network" AND  "your wireless network 5GHz". If you don't separate the broadcasts, the TC sends both out at the same time and picks what is best for your device. Thereby always getting the very best that you can.

     

    Now, I have made an assumption you may have an Apple router of some description but if you don't, can you do that, or something similar on yours?

     

    If you can't, then ignore me and hope you can get it sorted soon. Nothing more infuriating. Thought I'd mention it on the off chance it may help.

    Hi Tim,

     

    Thanks for the explanation.  I am using an ASUS RT-68U router.  Not certain what you mean by separating the broadcasts, but the ASUS is a dual band router and I see two SSIDs.  One of the SSIDs is for the 2.4 GHz band and the other SSID is for the 5 GHz band. I see them as separate WiFi connections.

     

    I have both a late 2013 15" rMBP and early 2014 11" MBA.  With 10.10 installed I had no issues connecting the MBA to the 5 GHz band.  The MBP had intermittent 5 GHz connections.  As soon as I installed 10.10.1 Beta on the MBP, it caused my entire network to act very odd.  I was now unable to connect to the 5 GHz band on the MBP and get this, I now had difficulty connecting to the 5 GHz band on the MBA.

     

    Re-installing 10.10 on the MBP eliminated the instability on my network.  I can now connect again to the 5 GHz band on the MBA and the jury is out on whether-or-not I will be able to make consistent connections to the 5 GHz band on the MBP.

     

    I would have never have thought that the entire network could become unstable because of an operating system change.  But it did in my case.

     

    Cheers,

    Hi,

     

    I've just upgraded to 10.10.1 version of Yosemite to see that it can fix the problem with the dropping Wi-Fi thing... And guess what? My wi-fi still dropping like nothing changed. This time I really don't know what to do. I've tried restarting the mac like 4 times and nothing. Any advices?

     

    (Sorry for my english...)

    I see. Very interesting indeed. With the TC, the 2.4 and 5GHz can be one and the same, if you want, and not 2 distinct WiFi connections.

     

    I'm stumped. :-( hopefully it lasts.

     

    Very curious how the basics have failed on this one from Apple!!

    Hi Tim,

     

    Was not aware of that feature of Time Capsule.

     

    Let me ask you another question.  When I go into Network, Select WiFi, Select "Assist Me", Select Diagnostics and Select WiFi I get a list of available networks.  What I have found on my rMBP is that I get lots of bouncing around of available networks off of my router.  Sometimes I see the 2.4 GHZ SSID, sometimes the 5 GHz SSID, and sometimes both.

     

    Do you see similar erratic behavior?

     

    Thanks in advance for your help.

     

    Don

    Hi Don,

     

    I get exactly the same thing. Really annoying. Always wanted the fastest speed but always had to select it.

     

    I began doing speed tests and realised that there was no loss in transfer rate with the combined broadcast. Saved a lot of hassle.

    Have you tried to re-install? Seems to have worked for Don

    It's great that Apple finally acknowledged the issue, but it's also not great that it took them 3 weeks to do so.

    What's the point of having an Apple computer if you can't do the basic functions of a computer?

     

    Also, I'm wondering if anybody else had Wi-Fi issues before Yosemite.

    Before I upgraded to Yosemite, I had Wi-Fi issues in Mavericks (although not as bad as it is currently).

    I asked the IT in my dorm (I attend college, so I have no access to the network hardware), and they told me it was a problem with my laptop, where it would try to connect to two different routers, causing the wi-fi to drop and reconnect constantly.

    I tried to run Wireless Diagnostics, but that app is really pointless if I don't have access to the hardware, as it asks me to try and power off the routers.

    Interestingly enough, the dorm Wi-Fi was down for a few hours while the IT people tried to restart it. And it still didn't fix the problem.

    I really think that Apple is hurting one of their main consumer groups: college kids, with their inability to fix their issues.

     

    I'm really hoping the Yosemite hot fix will fix the issue I had before, or else I'll just go from bad wi-fi to extremely worse wi-fi to bad wi-fi.

     

     

    Edit: Oops I did not read Timmy's post. Seems like he had an issue with Mavericks as well.

    Hi bskim,

     

    Sorry that you are having issues connection to the WiFi at your dorm.

     

    For others that are following this thread, I too have issues connecting to the 5 GHz band.  I have read in this thread that changing the channel to a lower number may improved connectivity to the 5 GHz band.  Thought that I would give this a try.  On my ASUS RT-68U I changed the channel for 161 to 48.  Since making this change several hours ago I have had the most stable 5 GHz performance since I updated to Yosemite.

     

    Bskim, I know this will not help you as it sounds like you are working with a "community" network.  Others with their private wireless router might want to consider changing the channel on their 5GHz to something below 100.

     

    Cheers,

     

    Don

    Hi All,

     

    Having made the change in channels on the 5 GHz band from 161 to 48 on my ASUS RT-68U router I continue to have stable 5 GHz connection though the evening.  With Mavericks, I had no issues using channel 161.  Problems began with installation of Yosemite.  I am beginning to wonder if this is a router problem that co-incidently began when I made the switch to Yosemite or, is this just a Yosemite problem.

     

    Cheers,
