Q: Wifi problem since 10.11.2

Hi,

 

I have some Wifi issues since I installed 10.11.2.

Before all work perfectly and since 10.11.2, my wifi always disconnect and the reconnect.

 

Do you have also new problems with Wifi? and maybe a solution?

 

Thanks

    This is what appears in my wifi.log when it disconnects.

    I too have the same problem and i tried all - removing network config files and re configured the router.. also reinstall OS X(twice) - no improvement .

     

    I have used wireless diagnostics tool and capture the below log -

    It seems you have the same error than me with the same reason:

    I have the same problem and found it will keep disconnecting during file download if the wifi signal is not strong enough.

    When I moved to somewhere near the router, the wifi was perfect.

    My signal is maximum. My Macbook is in the same place than my router.

    same problem here.

     

    everything worked fine, but after the update to 10.11.2 my macbook doesn't get a valid ip address anymore.

     

    what a great update!

    Hi Folks,

     

    same problem here. But as one fellow reported earlier. I have this problem just at one router (in my office). At home everything is fine.

    In my case, the connection will be dropped if the rssi of the wifi is lower than around -50 dBm.

    Is there anyone similar ?

    Between this and zapping the PRAM should be the first thing tried after an update that seems to have issues.

    I just updated to 10.11.3 beta 1. WIFI connection is more stable. But still some disconnection when I download.

    I have the same model and I haven't had any issues since 10.11.2--the first without issues for me. Speed was always my problem since 10.11 even in the betas. Since you are on the beta, be sure to report this problem using Feedback because it will send in your wifi internal details directly to apple.

     

    Something I would try before is this:

     

    1. Delete your wifi connection completely out networking and shutdown.

    2. reboot your modem after leaving it off for 30 seconds or so

    3. reboot and Zap your PRAM and reset your SMC

    4. recreate your wifi connection on your Mac and test

     

    In one of the betas I had an issue with wifi, it wasn't exactly the same, but doing this fixed the problem.

    I already tried all these solutions. It didn't fixed my problem.

    Yes I reported this problem using Feedback.

    I have found reinstalls don't work well either. What I did last time that did work well was I made a Time Machine backup. Then I plugged in my USB drive with El Capitan 10.11.2 and booted from it. Then did a clean install. When it was done it asked me if I had another computer I wanted bring in apps and files over so I told it the time Machine backup and it brought in everything perfect on a clean install.

    Reinstalls and repairs always end up with the same issues or worse. This actually worked.

    Hopefully it all gets resolved soon and >>esteban108, make sure you send feedback or a bug report too.
