Q: wifi keeps dropping since Yosemite upgrade

Since upgrading to Yosemite, my previously-stable (with Mavericks) wifi connection keeps dropping. I have to click the wifi icon and re-select my network every minute or two. I have turned off bluetooth and uninstalled/reinstalled wifi and my networks. I have rebooted multiple times. No luck so far. It appears that others are having similar problems. Any solutions at this point?

    I got a temporary fix for this BIG problem for MAC PRO RETINA users until Apple figure it out 

    Most of us have Torrents programs just start downloading any torrent file and put the down and up speed at 5 kB/s the connection will not drop when doing this

    and for gamers you can just stop the download when your in internet game not before

    we really hop apple will fix this soon.

    I have the same issue, and I tried 1. Deleting all the old WiFi networks from my list (there was around 50) that I no longer used  2. Deleting the contents of the /Library/Preferences/SystemConfiguration directory and re-booting and 3) running in wifi monitoring mode, none of which had any effect.

     

    However, what has worked, is switching off WiFi on my iPhone which sits next to my MacBook !  I noticed that when I connected to this new network using wifi on my MacBook, my iPhone somehow inherited the wifi name and password and connected to it as well automatically.

     

    By switching wifi off on the iPhone, suddenly the MacBook stops dropping the connection which was happening every 60 seconds or so and is now solid on all the time.

     

    No idea why, but it's working for me

    I spoke to soon - delete that, problem is back after a brief period of being OK.  Nothing to do with the iPhone

     

    Sorry guys

    Kludge workaround:

    Open Terminal and "ping -i 6 192.168.0.1"  (or whatever your WiFi gateway address is)

    This will send a "keep alive" signal over wifi every 6 seconds.  I tried -i 10 but it wasn't as reliable.

    You do have to get an initial wifi connection so that a route is setup, but after that the wifi connection is solid (like before Yosemite!)

    I can fold down the lid on my MBP with the Terminal running and it restarts when I open the computer again. 

    Put the terminal in the background and compute away.

     

    You could be pinging a public address, but that wouldn't be very nice, would it?

     

    Does anyone know how to setup the appropriate "keep alive" time for the wifi network drivers?

    Wonderful upgrade, Microsoft quality control must have tested it......... my MBPr 2013 has frozen 3 times in 1 hours since upgrading

     

    next time I need to upgrade my notebook I will consider other systems as I will no longer pay top dollar for an Apple product that is now no better than

    Microsoft's OS & Google android

    I dared to dream and installed the update. I then adjusted my router settings from B/N-only back to B/G/N. My wi-fi seemed stable for a while, but I did notice it started to drop eventually. Thankfully it reconnects on it's own so it isn't as bad of a problem as it was before; however, it's still annoying.

     

    My computer hasn't frozen as Mark808 stated.

     

    Has anyone else installed the update?

    I have the update as well; actually, the AppleCare tech *recommended* I download the latest update as a solution to my issue. 

     

    It did not work. 

     

    The problem persists and I'm getting the run-around from Apple.  They don't have a solution and keep suggestion it might be "one of my settings."  Well, to that end, the computer is two weeks old and I haven't adjusted anything; the settings are where Apple put them.

     

    Net: from all the comments, it seems this problem is NOT resolved.  One other user commented that this might impact his decision to buy another Mac down the line.  I concur.  I bought the Mac because I wanted this to be easy; so far, it's not.

    It is from Frontier ISP (branded) and on the label it says Actiontec MI424WR

     

    (oops, made an error earlier: switched from B/G-only to B/G/N. N seems to cause the computer to drop wifi at random intervals.)

    IIt appears that my issues with my MBPr and  Yosemite were related to a faulty main logic board in my MBPr late 2013. Every time I performed an upgrade or transferred large amounts of data such as an upgrade or backup my notebook would kernel panic or lockup in addition to random kernel panics. Initially it only happened infrequently. After upgrading to Yosemite the issue became markedly worse, Genius Bar diagnostic tests didn't show up any errors until recently when a whole string of errors came up. I also had my screen replaced as the coating was coming off.  At my last visit to the Genius Bar I told them that I had a lemon.

    Apple are now replacing my notebook with a new one under my AppleCare warranty perseverance pays off after a year and a half of issues.

    Have the same issue here.

     

    10.10.2 Mac Pro / Trashcan

     

    Have called Apple and have gotten the same sort of feedback.

     

    Seems to be computer specific for me. MacBook Pro runs fine in same location as does iPhone etc etc.

     

    Curious if people have have experienced the single machine issue - that it doesn't seem to be a problem on all machines.

     

    I've also noticed that the Mac Pro is always on 10.10.200 even if I reset router / settings / dhcp etc. Router is an Airport Express. It's a small network so it's odd that my Pro has taken the last possible IP...

     

    Any new work arounds? Have tried the trashing of the settings etc.

    Try this, it has been working for me:

    After trying all of this plus some, and calling and chatting with Apple, I finally found this in the Apple Support Communities, and so far it is sticking:

    "If you have a backup from 10.10.1 browse your backup and go to /System/Library/Extensions and copy the file IO80211Family.kext.

     

    First, shut down wifi.

     

    Next, in your updated system (running 10.10.2) go to the same path and make a backup of the same file. If you click get info on both files you can see that 10.10.1 had the version 7.0 and 10.10.2 has the version 7.1

     

    Now paste and replace the IO80211Family.kext file.

     

    To be sure everything is fine regarding permissions, run Disk Utility and press Repair Permissions.

     

    When finished, reboot.

     

    If you don't have a backup I can try and upload mine, but I'm not sure it will work across different devices.

     

    Please let me know if this helped."

    I'm joining the club. After updating to OS X Yosemite 10.10.2 my MacBook Pro (Retina, 15-inch, Early 2013) will not upload internet pages or update email even thought the wi-fi icon is fully enabled. The Safari loading bars stops after a short distance. This is happening at home and work so it's not a router/service provider issue. It must be related to the last update because it worked perfectly before that. Now I must stop and restart wi-fi every few minutes.

    Absolutely sick of this problem. Bought a brand new iMac last November. Macbook Pro on OS 10.8 worked fine at my office building, new iMac worked fine when on Mavericks (pre-installed), and now constantly disconnects since upgrading to Yosemite. I've tried all sorts of fixes from various websites, and I'm still plagued by this. There's no consistency to the problem, works fine for a week then suddenly starts playing up again. The amount of time I've wasted constantly switching the wifi off and on again in the middle of trying to do stuff and the amount of time I've wasted looking up solutions and messing about with settings is ridiculous. It's a simple function even a cheap phone can handle – locate your wifi, stick a password in and that's it's connected. I shouldn't need to 'fix' anything with an out of the box (expensive) product.

     

    Various software updates have claimed to fix this, but haven't. Seems like Apple have put forward no proper soloutions and are just hoping everyone can fix it themselves or give up and just put up with it. *bangs head against desk*
