Q: OSX Yosemite Wifi issues

Dear norge83

I agree this is a shambles from Apple. Have you checked that a clean install of Yosemite 10.10.5 on a USB stick has the same problem? I'm not sure which hardware you have if it is like mine (MacBook Pro 15" Retina mid 2012) a solution could be to check if an Apple authorised reseller can install a newer version of the Airport Extreme card. I have colleagues that work on more modern hardware and have no problem at all. Mind you this might not work at all and of course can't be done in an Apple store. If you still have warranty I wouldn't recommend this as well, but then I would pester the Apple store to resolve the problem. In my analysis there seems to be a problem connected to specific hardware. You also could consider to downgrade again to Mavericks. Not ideal, but there is a good chance your laptop will work.

No wifi for me either on 13" Macbook pro retina :-(

Hurry up Apple - this has gone on long enough!!!

You're a star.

10.10.5 helped me on my desktop machine - havent tried my macbook air yet

will report back later after I do....  fingers crossed...

No changes for me.

I bought a replacement wifi card of the same model and had no change in the behaviour for my issue. USB Edimax dongle still runs perfect.

10.10.5 helped me on my macbook too (at least from yesterday). Still under observation - hope this time no more patch / workaround required :-)

I must correct myself. The latest EC Beta has improved the situation. However there are two things.

Firstly it looks like they have hacked their way a temporary solution (hopefully temp because it's still a bit disruptive). Mine appears to detect the connection drop and self restart. Causes my downloads to stop but they fortunately will restart where left off so long as I notice they stopped. Not immediately apparent to me since the difference between little grey icon and little blue icon gets lost in all the other visual details. This is however better than before. So far...

Secondly now my computer repeatedly either crashed or self reboots. Seems to do with the sleep function... Can't win. No more meters after EC for me.

Arrgghh... It's borked again... I should have known I have got my hopes up a million times and been let down each time.....

Just discovered that it appears my EC Beta doesn't properly have Edimax USB Wi-FI dongle support as Yosemite did. Seems if I have the dongle plugged in I often get a complete system crash with or without an automatic rebut and sometimes a message saying so but not always, after the computer has gone to sleep. Just what I need. My best work around is now broken... again!!!! Apple stop doing this. OK So I am a beta user and I deserve and expect this. Just a shame that proper public releases still don't fix my Wi-FI issues. More do I have the time to reinstall. Oh well.

Please, he didn't threat anyone. Please do not hold against him personally just because Apple doesn't make reliable computers anymore. All company in current economic climate are driven by maximizing profits at any cost. The primary objective is to meet market's expectation and satisfy shareholders. It's a fortune making business and not the computer company anymore. Making good quality, dependable products is secondary. It's wide spread, very sad event affecting life's quality of every modern society dependable on technology. It's too bad that not every one can see it and realize importance by demanding nothing by the very best for their hard earned money. I'm supporting you Ikrupp 100% and please everyone do not lower your standards, expect the best.

Sorry, I meant "timmjr".

Please, do not wait for the Apple to fix your Wi-Fi problem. They always created some Wi-Fi connectivity issues as long I can remember. I do own Apple computer and portable equipment for many years and do not want to say that but the only resolution or option you have left is purchasing a Windows operating machine. I do have the same Wi-Fi problem since downloading Yosemite on my late 2012 i-Mac last year. My wife's Mac Book-Air works great on Maverick. I should never "upgrade" to Yosemite.

I'm dead too. Was doing the delete the config files and restarting fix for a while. Probably like 2-3 times a month since yosemite came out. Last week my wifi dropped and nothing is working. Combed through every "fix" online and nothing. Even replaced my airport card because someone said maybe that crapped out since my macbook pro is from 2008. Still nothing. It ***** with the new OS set to drop next month. Part of me hopes it fixes all this and part of me is scared to upgrade again and have even worse problems. Should never have left mavericks...

Dear cairoli91

You could go back to Mavericks. If you have regular backups you could restore from a pre Yosemite backup and then restore all your documents from a backup you made just before the restore from the old backup. Since I have not tried this myself to be on the safe side I probably would also copy my important files onto an external hard disk for safety. App store purchases can be reinstalled from the store if need be, but you could also copy the Apps to the disc.

If you want to do a clean install you can also re-download the Mavericks installer from the Purchases tab the App store (http://osxdaily.com/2013/11/01/re-download-os-x-mavericks-installer-mac-app-stor e/). Of course rolling back to an older operating system is not really recommended. I used this method to create a clean USB installer for Mavericks to test if my hardware had a problem.

Before the roll back I would probably test a clean install of Yosemite on a USB stick or starting the Mac in Safe Mode (Try safe mode if your Mac doesn't finish starting up - Apple Support) to check if there is not something else broken.

The danger with the roll back of course is that some of the updated App's won't work for Mavericks and that of course you have all the security holes that the consecutive Upgrades have closed. The procedure with the clean install from the Mavericks installer is not as straight forward as the roll-back from the Time Machine Backup
