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)

    Well, this problem exist from first developer previews. Only solution is clean OSX install or at least it looks like it's. For me this worked. I bet Apple knows about it which is good and bad news at the same time. Still if you seriously want to solve them reinstall OS X brutal but only solution only clean install. Unless Apple finds fix

    This is my story. New iMac (had it for about 6 weeks)  installed with Mavericks. Upgraded to Yosemite not long after it was released. Worked well for about a week. Then had WiFi issues. After a couple of chat sessions and a few phone calls with Apple support and numerous attempts to fix the problem, we couldn't. Apple suggested it might be hardware related but discounted this after the computer successfully went into Internet Recovery mode. I've fixed this issue by buying a Belkin Powerline adaptor. Works great. Hopefully, the fix will be in the next update.

    As I noted in a previous post, Step 1 of this: http://osxdaily.com/2014/10/25/fix-wi-fi-problems-os-x-yosemite/ has resulted in no more wifi issues (dropouts) for the past 2 days.  Wifi working normally again.

    This solution worked for me:

     

    The first step is to click on the WiFi icon and select Open Network Preferences. Make sure WiFi is selected, turn WiFi off, click the Advanced button at the bottom-right corner of the window, remove your network from the list of preferred networks, click OK and then Apply.

    Once that’s done, open Keychain Access from Spotlight by typing keychain. With Keychain Access opened, look in Local Items and System for your network. If you see your network listed, delete it.

    When that is done, reset the System Management Controller (SMC). To reset the SMC, you'll need to power down and disconnect all peripherals (such as external drives, printers, etc). Connect the power adapter. Then, press and hold shift+control+option and press the power button and release everything together. Your Mac should not turn on, but you may notice that the power adapter LED changes.

    Once that’s done, start up and then turn WiFi back on and reconnect to your network. If there is still poor WiFi connectivity, chat us back at getsupport.apple.com

    Same here, this is a joke. 2013 MBPr. Can't stream airplay, will cause a total wifi crash. On one occasion, it actually caused the first crash I've ever had on this machine.

     

    When streaming to Airplay (everything updated), it will just lockup, then disable wifi on my macbook completely until I restart all browsers.

     

    This is very disappointing, I expected better from Apple. Between this and iOS8, it appears I need to reevaluate my trust.

    I have intermittent connectivity issues on my MacBook Air. Never had a problem with Mavericks. All other equipments - iPhone, iPad and a PC, work fine. I need a fix.

    This worked for my 2012 Mid Macbook Pro. Thanks for the help. Hopefully my laptop will stay connected. I tried everything else and had no luck,

    I hope they fix it real soon. It's getting really annoying, happens every 2 minutes. It took me 10 to be able to get to this discussion. Turning off handoff helped me, but now i don't have handoff

    I haven't read this thread clean through, seeing it is so huge. But there may be a kind of phantom cause which is not yet fully known: USB3.

    Just wondering: it seems there is an issue with USB3 overcrowding or creating disruptive noise on all other WiFi and Bluetooth bands:

    This noise can radiate from the USB 3.0 connector on a PC platform, the USB 3.0 connector on the peripheral device or the USB 3.0 cable. If the antenna of a wireless device operating in this band is placed close to any of the above USB 3.0 radiation channels, it can pick up the broadband noise. The broadband noise emitted from a USB 3.0 device can affect the SNR and limit the sensitivity of any wireless receiver whose antenna is physically located close to the USB 3.0 device. This may result in a drop in throughput on the wireless link.

    No joke, the source is an Intel White paper: http://www.intel.com/content/dam/www/public/us/en/documents/white-papers/usb3-fr equency-interference-paper.pdf

    So I wonder: do al of the plaintiffs here have a (per definition external) USB3 HDD/SSD/Device in active duty?

    Thank you!

    Hi,

    We tried this solution on our Macbook Air this morning, hoping to not only get the wifi working, but also to see if we could recover the hijacked space that is now reporting the hard drive as full, when prior to the Yosemite install it was just a little less than half full. We can no longer back up the iphone or do any other simple tasks. It is showing that 123GB are being used for "other" ?

     

    This makes the computer useless at this point. Any idea how to fix that issue please?

     

    Too early to tell if the wifi solution worked, but even if it did, it would still be of no use without recovering the lost space.
