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'm experiencing this too on my MacBook Pro mid '12. However, it occurs only on specific networks (eduroam mainly).

    I'm not even getting into wireless. All I get is -

     

    "Wi-Fi has the self-assigned IP address 169.254.186.245 and will not be able to connect to the Internet."

     

    But I am on the internet through the cable connection

     

    iMac 2011 using a delivered today tp-link TL-WR2543ND 450Mbps dual band wireless N Gigabit router.

     

    I am assuming it is a Yosemite problem because my iOS8 iPad is receiving wireless.

     

    Am I correct in thinking that the router can do both a cable connection to my iMac and have a wireless connection simultaneously.

     

    And that I need wireless and bluetooth to use airdrop between my iPad and iMac.

     

    Come on Apple get it fixed

    Your TP-Link allows at least disabling WMM Feature (Wireless Advanced) but unfortunately not disabling frame aggregation. Does it help disabling WMM?

    Some success with advice of Apple Care. On MacBook Air I reinstalled OS, refreshed DHCP and set DNS settings away from my ISP to Google's 8.8.8 something or other..... On iPhone, reinstallation of iOS but this time tethered to my computer - totally fresh install - seems to have improved performance in my home office with respect to measured speed and consistency of speed and consistency of signal. Now the bigger test will be when I am at my place of work where the disconnect problem really happens - in a few days I return to the office. One thing I learnt from Apple, the experts amongst you will no doubt know.... if you hold down the alt key whilst clicking on the wifi symbol on the top right hand corner of the screen, you get a bunch of other data about your wifi connection from your router and one data is the transfer rate (TX rate). On my Air, when right by the router, I now get the theoretical max for AC on the device of some 867 MBS at times, my desk top a bit more variable - but I have not reinstalled the OS on it. Indeed writing now the speed on laptop much better from the router than the desktop.

     

    Worth a try as it does not look like we are going to get a fix in the very near future and this did not take me very long

    The DNS servers I use are assigned by DHCP, each of which finally auto forwards to Google DNS.

     

    There is a big problem with changing the DNS to point directly externally, rather than use an internal one, in a corporate environment you will not be able to resolve local servers.

     

    Not really a viable solution.

     

    The only viable solution to this nightmare is to wait for apple to fix it, how long you want to wait is entirely up to you, but for me if a resolution hasn't been delivered 4 weeks after the launch date of Yosemite, then I'm for one going to roll back to Mavericks, possibly skipping Yosemite all-to-together, or at least until I read that a full resolution has been found.

     

    To be honest I'm thinking about rolling back anyway as I'm not overly keen on the new look, it's almost as though Apple has lost it's style and class, once with a class comparable to Sony & Mercedes, I would say personally that they are now comparable to LG and Ford.

     

    As previously commented on this thread, we are all clutching at straws over this matter, nothing has worked to resolve the problem, albeit some of the solutions have made life a little simpler for some, the problem always seems to return.

     

    I dread to think of the commercial cost for business users due to this problem, I'm in a lucky environment where I still have machines on Mavericks that actually work, so it's not effected me so much.

     

    But what with Yosemite being a free, almost forced upgrade, there must be thousands of hours wasted just due to this nasty little bug.

    Apple says this:

     

    Engineering has requested the following information in order to further investigate the issue:

     

    Please option-click the WiFi Menu Extra and launch Wireless Diagnostics, then attach the log file that is created to a bug report at https://bugreport.apple.com/


    Please compress any bundled files (e.g. nested folders) prior to uploading.

    You must be funny. Could you please post this to apple?

     

    The Broadcomm is colliding beacons. Here's what happens if you trace an intelligent accesspoint to WiFi aggregation with Mac Computers.Bildschirmfoto 2014-11-04 um 00.50.49.png

     

    Thankful, lancom hotspots are stable enough to compensate

     

    If you disable frame aggregation and WMM/(U)APSD, you see, what a Yosemite Mac Computer does within WiFi network:


    [WLAN-STATUS] 2014/10/29 02:11:14,637  Devicetime: 2014/10/29 02:11:15,025

    WLAN-1: 2 beacon(s) not picked up (XX-------)

    Tralala

    LastSubmit 100, LastCleanup 184, LastStop 38491, LastStart 38487)

    current modem load is 3%

    BB hang detect: BB state still changing, no hang, BB panic status 0x00000000

    You're playing beacon pingpong! This also carriers over to all participiants within SSID / Roaming solutions.

     

    There also strong discussions over at aruba, ubiquiti and lancom. All of them come to the conclusion, that disabling frame aggregation and WMM/UAPSD will help but not to get back old performance. We start to keep out Macs from hotspot solutions to keep the others online. This cannot be traced by Mac Diags. Go trace at accespoint sites. Then talk to broadcomm. Then fix driver.

     

    Thank you!

    I am floored by the number of people, myself included, who are having this same problem (of dropped WiFi connection with only possibility of regaining is by turning off WiFi and turning on again) after "upgrading" to Yosemite... not just on this thread but on numerous other threads as well. I've read some suggestions that it's an interference with Bluetooth, and that shutting off Bluetooth will solve it. But guess what, I USE BLUETOOTH (as I assume do many of you out there).

    iMac 27" intel Core i7

    OS X v10.10

     

    And still... this? Seriously?

    joeMJ: Not sure who you're talking to. No one in this community  thread has the power to fix the issue. You (and everyone) need to file a bug report with Apple at https://bugreport.apple.com/

    Hi, I have tried everything what I have found on internet and nothing helped. I am waiting for an upgrade. I hope Apple will release it asap.

    I have run the diagnostics report but when I click on the link it tells me I have to be an Apple developer. Is there any way of sending off my report without registering as a developer please?
