Q: OSX Yosemite Wifi issues

Hi there,

 

I upgraded my Macbook Pro Retina 15" (mid 2014 revision) to OS X Yosemite last night and am now having issues when using my home WiFi connection. Whilst it connects to either the 5Ghz or 2.4Ghz network, it is basically unusable. Web pages take minutes to load (if they even load at all), dropbox doesn't sync because it can't get a connection and even trying to get to the router config page is extremely slow and hit/miss.

 

Tethering to my iPhone seems to work ok, as does using my home network via wired ethernet.

 

Are any others having problems with Yosemite? Wifi was working fine on Mavericks.

 

Tom

MacBook Pro with Retina display, OS X Yosemite (10.10)

    Hi Morten, thank you!

    There probably is a collision between IPv.4 and IPv.6 somewhere in Yosemite, exactly as I've surmised.

    As I myself am still running Snow Leopard, and my Macs being too old, no way to test. Snow Leopard still has the ability to switch off IPv.6, much preferred in the old days.

    Thank you so much, again!

    You are welcome.. I would insert two images here so that you can see what it looks like. But Safari in Yosemite freezes when I hit "Choose Image" ;-)

     

    New Topic I Guess ;-))))

    Where are your images/screenshots? No links found & I'd like to see them! Oh- I get it. Sorry about Yosemite.

    Thats it the point.. I click the little camera icon in this here message composers... Then try to upload from the computer by hitting 'choose image'...

     

    At that point Safari Freezes and my console fills up with my favorite LOVE to hate feature of OS X === Sandbox ;-)

    Which is always a major party pooper.

    after spending few days of internet connection being dropped down constantly after upgrade to Yosemite I finally found a solution.

    Go to Network settings, click Wifi and than Advanced. In Advanced click TCP/IP column at the top.  Under configure IPv4 change to manual and change all the settings in IPv4 Address,Subnet mask,Router and you should be all set. I've copied all the info from my perfectly working Macbook running on Snow Leopard. My iMac is running perfectly since I changed all the settings from yesterday. Good luck, it works !!

    Right, Morten,

    with Snow I've never had to deal with Sandbox, so I was almost unaware. Can you upload the pic to Dropbox, Phototobucket.com http://photobucket.com/, Imgur.com http://imgur.com/ maybe?

    I'll manage to get registered if needs be.

    Well, Nick,

    this seems like a very worthwhile suggestion! Doesn't change my suspicions, though. Indeed confirms them.

    Thank you!

    Got it, Morten. Great.

    Seems you cannot altogether switch off IPv.6, but you can derail it to "link local" only. Probably worth a try. Link local most probably has an IP starting with 169. and in most cases is as castrated as can be.

    Darn, a link local adress starting with 169. is still IPv.4. Sorry, I'm still educating myself. Link Local IPv.6 adresses come with the prefix fe80::/64.

    Good luck!

    So a weird thing just happened to me. I have not read through the thread and have no idea if this has been discussed here. Anyways, i have two macs that upgraded to Yosemite with no problems. Went to upgrade a family members MacBook and experienced wifi issues. Slow speeds... No connection... I noticed they have an older version of Dropbox app installed. Disabled auto start of Dropbox and restarted Mac. Wifi works just Fine. Not sure if it's a solution but maybe someone can verify if dropbox app is somehow causing a problem and if it solves anything to turn off auto startup and restart. I have had Dropbox cause various system issues in the past.

    Hey people,

    Say no more. You know what has happened with the introduction of OS 10.10 Yosemite? IPv.6 has just become the system network default!

    Everybody with Mavericks' or older migrated IPv.4 settings, as well as everybody with older, IPv.4 hardware (e.g: router) has been left in the dark.

    As well as every end user dependent on an ISP not capable of IPv.6 (yet).

    The solution is simple: go to your System>Preferences>Network>Advanced and simply manually copy or revert your IPv.4 settings from an older/migrated Mac or restore some kind of IPv.4 setting.

    I' m quite confident this will work.

    Thank you, nickfromromeoville, to bring me on track.

    With this, I wouldn't wonder if this weren't the same with IOS8 also...

    you can turn it off

     

    and if you run nettop  in terminal you will notice that tcp6 is what is causing it to run slow

     

    open  another terminal

     

    networksetup -setv6off Wi-Fi

     

    type your password

     

    turn wifi off and on

     

    wait for established tcp6 link to disappear in at top of nettop window

     

    then run networksetup -setv6automatic Wi-Fi


    type your password

     

    turn wifi off and on

     

    problem gone
