    I have just installed the public release of Sierra and am noticing that my wifi is dropping occasionally on my 2015 15" Retina MBP. I have to disable and re-enable the wifi when this happens for the to connection to restore. I had no problem under El Cap.

    Anyone else having this issue?

    P.S. I'm using an Apple Router.

    I'm experiencing the exact same issue. Also mid 2015 15" Retina MBP and didn't have any issuea with El Cap. I have the issue when connected to Ubiquiti AC PRO access points. I lose connection about 4 times a day. Very annoying.

    I don't know why this issue keeps rearing its head every time there is a new version of macOS. Did you do an upgrade or a clean install? I did an upgrade. Everything else has been stellar except for the wifi issue.

    I ran every beta up to GM and did an upgrade install of the public release just in case.

    This is the first time I *haven't* had a wifi issue.

    Having the same problem. Only way to get wifi working again is to turn it off and back on. Running a clean install of the GM release

    I'm also experiencing this; upgraded from El Capitan to the GM release. The issue wasn't present before, happens on both 2.4 and 5GHz. The WiFi will randomly drop out every 2-3hrs, seemingly randomly. The issue doesn't occur on my iPhone.

    This is now a consistent issue and becoming increasingly annoying. Anyway to diagnose this or any ideas on how to fix. Is there a way to reset network settings on a mac like on iOS.

    My 2011 Mac Mini is also dropping the wi-fi. I don't have to turn off the wi-fi; I just re-choose my network.

    Did a clean install to try and rectify the situation. Still dropping connection about 4 to 5 times a day.

    Same issue on El Capitan. I did clean install month ago on my retina Mac Book Pro 2015 (El Cap) and Yosemite on 2010 Macbook Pro. Having these issues since the new instal. Previously it was completly OK.

    I have no problem connecting to wifi, but the speed though is seriously sluggish. I'm in Malaysia, so bear with me on the figures. On my iPad, I can get a speed of about 20 Mbps but on my late 2013 rMBP I could only get 0.4 Mbps. Anyone facing similar issue?

    Yes, it's Sierra. My mid 2011 Imac does the same dropping WiFi. 5 feet away is my wive's newer Imac and it does not have this issue. So it is Sierra and specific hardware related.

    Same issue here on Retina Macbook Pro 13''. It seems worse on 5ghz networks.

    Has anybody tested whether this is fixed on the beta of 10.12.1?

    You could be right about the 5ghz networks...

    My Mac Pro connects to my 5GHz wireless network and I'm running 10.12.1 beta release 3.
    Already had 2 pauses/dropouts with wifi this morning - so still not resolved :/
    Never had the issue with 10.11.x

    Guys, I've got a similar problem. I'm on a Macbook pro early 2011, my wifi doesn't drop but it is unbelievably slow (something like 56kbps with very very high ping latency), and every device connected to the same wifi (mobile phones, iPhones, other computers and so on) experiences the exact same speed problem, it is like Sierra is screwing my entire wifi hot spot.

    I've found this:

    but it doesn't matter how hard I try, at least for me it doesn't solve anything.

    I am sorry to say I had to give up, the only solution that worked was downgrading to El Capitain with time machine.
    Waiting for a future release of Sierra explicitly addressing this annoying issue.

    i can confirm this too, and the "workaround" with setting wifi location is older than the declaration of independence...this has been a "feature" for several OSX point releases (but not limited to) now.


    Get the point? :)

    i had similar issues with Capitan or Yosemite, can't remember exactly...
    what fixed it for good was fresh installing the from scratch (USB boot), instead of upgrades via Appstore.

    I always do clean installs. I have the issue.

    after installing Sierra from scratch, i didn't have the issue. Once the update to 10.12.1 appeared some time after that and was installed, i have the Wifi issue too....after waking up from sleep i need to disable and reenable wifi in order to get working internet.

    wtf is this...Apple slowly but surely losing mojo.
    Oh btw i also have that garbled screen issue when waking from sleep....imac 5K retina machine

    Apple has almost always had Wi-Fi issues early on with a major version update.
