Q: OSX Yosemite Wifi issues

This whole situation is nonsense.

I bought my Retina Mac Book Pro to avoid the situation we are (all) having right now. For years my Windows based laptops gave various problems and the switch to Apple was to alleviate all those issues.

I've been sold a machine which is simply not fir for purpose. The aftercare service has been simply awful. Yes, lots of warm words, but no solutions or ownership of what is an obvious fault.

Some of you guys on here are clearly technicians who might just like playing around with things, but as a simple user all I'm looking for is a decent return on my £999 investment. Close to £1000 is a substantial amount of money in my view.

So, what do we do? Apparently nothing is the answer. It's a case of fiddling around with settings which potentially could make things worse if a user and not a techie or sucking up the fact that Apple have got yer money and frankly, don't care.

Hi.

Tried all the solutions, the one that semi worked for me was the 5ghz net. 2,4 is only timingout. But even som the speed on the 5ghz are affected by sudden drops.

This may be a very dumb question but you speak of a modem rather than a router - I am puzzled about how the position of a modem is relevant to a wifi issue, so could you please enlighten me?

THIS WHOLE SITUATION IS RIDICULOUS... NOBODY WANTS TO BUY A CAR AND UNDERSTAND ABOUT MECHANIC OR ELECTRIC, WE JUST WANT THE CAR RUNNING.

(to no one in particular)

folks can you please state the version you are reporting on, instead of "latest", "current", etc ???

Some people mean 10.10.2, some 10.10.3, or I suppose maybe even 10.10, thanks

Running 10.10.2 on 2014 MacBook Air wifi works just fine on the airport extreme at home, but continuously disconnects from RADIUS server802.11 a/b/g/n/ac at work.

Yosemite has repeatedly been reported to run into WiFi trouble on a WPA Enterprise network. So that will be the answer in your particular case. Sorry.

This problem has been driving me a bit nuts the past 2 weeks.  I've installed and reinstalled many times to see if I can narrow things down a bit.  Here is what I've noticed. 

Typical bad behavior:  Machine after reboot, signs into WiFi with little or no problems.  Machine goes to sleep/wake cycle, WiFi can no longer connect or connects after a long time with DNS unavailable.  Moving from AP to AP (different networks), would result similar behavior as it requires system to go into sleep...

Systems:  Macbook Air 11" (2011), Macbook Pro 15" (2011)

OS:  10.10.0, 10.10.1, 10.10.2

Upgrade install - 10.9.5 works, 10.10.0 works, Upgrade to 10.10.1 works, Upgrade to 10.10.2 WiFi becomes very intermittent... 

Clean install - 10.10.0 works, Upgrade to 10.10.1 works, Upgrade to 10.10.2 WiFi becomes very intermittent...  (iCloud Signed in at install)

Clean install - 10.10.0 works, Upgrade to 10.10.1 works, Upgrade to 10.10.2 WiFi Works!!! (Don't sign-in to iCloud)

Upon further debug, the issue seems to be the WiFi Hotspot setting synchronization between the iCloud and the new OS device.  I've also tried to disconnect iCloud from a system that was setup with iCloud sync, this is where it gets bizarre...  I can uncheck pretty much everything, except iCloud Keychain.  For some reason, as soon as I uncheck the iCloud Keychain sync, it automatically turns it back on.  I've tried to do some more debugging on this but finally gave up.  Without iCloud sign-in, WiFi seems to be as solid as a rock.  Is there anyway to go into iCloud to "fix" individual keychain access?  I.e. is there a way to go into iCloud via the web interface and remove/reset iCloud Keychain? 

Hope this would help you debug if you are having WiFi issues... 

Cheers,

George

Significant wifi issues with 10.2.2 on my Late 2009 iMac. Little, if no, problems with my Late 2011 11" MBAir. Working on the same desk and the MBAir is fine. iMac drops the connection frequently.  Bluetooth is off on the MBAir. BT is on with the iMac.

Bought a Macbook Air 13' 4 months ago. Since the update my Wifi just randomly stops working every 5 to 10 minutes. Very frustrating! Hope problem will be fixed in new update soon.

STILL rock solid here days after implementing my fix. Went from no webpages at-all-ever on 10.10.2 to perfect-fastest-ever web access for 3 days so far without a single problem.

Do you happen to do a lot of downloading? Downloading pretty much anything is where my computer comes to a standstill.

I've also tried to disconnect iCloud from a system that was setup with iCloud sync, this is where it gets bizarre...  I can uncheck pretty much everything, except iCloud Keychain.  For some reason, as soon as I uncheck the iCloud Keychain sync, it automatically turns it back on.  I've tried to do some more debugging on this but finally gave up.  Without iCloud sign-in, WiFi seems to be as solid as a rock.

Makes sense: iCloud sync makes for a huge amount of network chatter. If you want to turn off iCloud Keychain (which would make sense if you do not need it on any Apple device you own), make sure it is killed on all your Macs as well as all your iDevices, including your iPhone(s). If only one of them is still active, the iCloud Keychain will reappear. That is the soul and purpose of a synching service after all. That part seems to have been designed well, after all.

If you turned off iCloud Keychain on all your devices, your iCloud Keychain is removed from the cloud. If you chose to delete the keychain items from your devices when you turned off iCloud Keychain, your iCloud Keychain is also removed from those devices.

Tough decision, but maybe a good solution for you- and hopefully others. Good luck!

Maybe some history is in order here. Anybody correct me if I'm wrong. This is just from memory/ the top of my head.

In the earlier days of computing, computing was not really personal yet. You had very cripple computer sharing time on powerful mainframe computers.

In the 80ies, personal computing made a breakthrough, possible through technical innovation. Al data began to be saved locally.

These days, we seem to be experiencing a shift in paradigm. Although local storage and computing power lie well within reach of the nowadays technical possibilities and have been so through the last decade or so at least, the powers that be seem to be wanting us to get back to the time sharing era.

Hence iCloud, Creative Cloud and all other forms of cloud-based solutions. Though very convenient, we should ask ourselves what we, as users, are giving up as to personal freedom if we use cloud-based solutions.

End of rant. I am just a concerned citizen and humble (Apple) computer user. With some basic questions.
