Q: High ping, slow wifi and packet drops

I have a MBPr mid 2015 with Yosemite 10.10.5 installed and my GF have MBP Air with 10.9.5. Same time, same location, totally different picture:

I run ping to local router

Mine:

Something is totally wrong with Yosemite wireless. When it will be fixed?

Apple doesn’t routinely monitor the discussions. These are mostly user to user discussions.

 

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

    I have this exact same issue. I'll be bringing in my laptop to the apple store and see if I can fix it. I'll let you know what we find. It's pretty frustrating. I'm using a brand new Apple Airport Extreme thats 5 feet away and get drops and ping times over 200ms too.

    It's still interesting, what happened to our books. But mine problem magically disappeared a week after this report.

    Please write back, what they said at at the app store.

    I am experiencing the exact same issue on my MBP from beginning of 2015. I am running El Capitan 10.11.3 and since one month I have awful wifi connection to any of my home routers (2x airport extreme, 1x fritzbox) without difference. While my iPad has wonderful connection, I have constantly a ping of 100-1000 ms to my own router and even frequent packet losses. If I restart it gets better for a while. I tried deleting the buffer on restart, changed some files (where it stores the preferd wifis) but nothing really helped.

     

    I hope they come out with a fix soon. It is no fun working on my MBP anymore

    This is really annoying. I have the same issue. My pings get dropped randomly, the wifi seems to be connected, the signal stays the same all the time, but I keep loosing packets.

    I have tried EVERYTHING. I think this is hardware issue. No software magic trick works. If anyone has any idea, PLEASE help us! Apple?

    The same story - MBP mid 2015 (osx 10.11.5) - huge spike and package lost.
    I tried to ping on other laptop (Win 10 osx) - 3-5ms. So the problem is in Mac for sure

    I believe I've observed the exact same thing. I did extensive testing:

    My analysis: https://robb.weblaws.org/2016/08/16/wifi-lan-performance-test-comparing-3-router s-and-6-devices/

     

    I submitted this as a bug to Apple; I'll update if I hear back.

    Wow, really nice research )

    For me is still not clear, why that WiFi issue does appear sometimes, but not always. Firstly I assumed that starts after getting out from sleep mode. After that I found that WiFi connection drop loose packages while I am downloading something. Today, for example, that works well again... something weird happens.e

     

    Is you research based on repeating behaviour (each time) or that happens "sometimes" also?

    Nope, this happens predictably, every time. I'm pretty sure it hasn't always been like this, though; maybe it only got bad in the past year? Not sure.

     

    Note, I'm really only seeing it on these local LAN connections to the Macs from other computers.
