OSX Yosemite Wifi issues

Here is another interesting hint. Previously I wrote that I am not able to connect to the 5 GHz low band (ch 36,40,44 and 48) with my MacBook Pro 15" Retina mid 2012. This turns out not to be entirely true. It may be possible that this bug only affects channels with 40 MHz bandwidth. I was connected to an Access Point earlier that run channel 40 at 5 GHz low with 20 MHz bandwidth and this seemed to be OK. Unfortunately I can't really test this hypothesis since I can't choose the BSSID I want to connect to anymore with the airport command. Also requesting a particular channel didn't really work. It would be great if Apple would have the facility for advanced users to set things like this. Apparently this was possible before OSX 10.6.

I ended up reverting back to Mavericks after awaiting patiently for each 10.10.x update. I feel terrible for people who bought a laptop/iMac post Yosemite as standard shipping OS. At this point, even temporarily, downgrading to Mavericks seems like a best bet (after back-up) until El Capitan .2 or .3 is out.

Have always upgraded to the newer OS right away since Tiger. This experience has really left me with cautionary tales and I will need to learn to deal with anxiety of not having the latest OS on my machine. But that is what it is. The lesser of two evils.

I hoped thad 10.10.5 would help with this wifi issues but nothing changed today after I installed the update 😟

I am a phd student and I can't work properly because the wifi is failing that often.

At the router Side I can't change anything because thats from the university...

Maybe I should Install Windows on my Macbook until the Problem will be fixed in a uncertain future.

An USB Wifi Stick is not possible because the university uses WPA2 Enterprise auth and it seems there is no one for this wich has mac drivers 😟

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is like mine (MacBook Pro 15" Retina mid 2012) a solution could be to check if an Apple authorised reseller can install a newer version of the Airport Extreme card.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".
