Q: OSX Yosemite Wifi issues

I BOUGHT A £3500 MACHINE AND AFTER YOSEMITE I MAY AS WELL HAVE BOUGHT A BRICK

APPLE HAVE MADE NO ANNOUCEMENTS AND BECAUSE OF THIS I RETURNED MY £3500 BRICK, GOT MY REFUND AND  DECIDED TO MAKE MY OWN MHACKINTOSH (£2200 WITH A 3K MONITOR) AND GUESS WHAT

IT WORKS JUST FINE , WITH NONE OF THE ISSUES YOU AND I HAVE BEEN/ARE EXPERIENCING

SO IF YOU LIVE OUTSIDE OF AMERICA AND PAID FOR THE SOFTWARE

BUILD YOUR OWN MHACKINTOSH

WHY

BECAUSE IT WORKS,

makes one wonder why though

dont it

i know this isn't helpful to the thread but really isn't it about time we said enough is enough to these so called innovators

this is my last post because I'm tired of my SONY phone waking me mid night (american posts) even though I've turned off the announcements, but the CONTINUAL updates ensure they are turned BACK ON

ring any bells APPLE

since Mr jobs died the MONEY MEN have basically ruined APPLE

i have be dying since day one to say my mhackintosh has had none of these issues

and one has to wonder why?

what is so different to their hardware to normal intel stuff seeing as they have now gone intel

anyways I'm tired of this and will continue to use unix, linux and apple over MS

BUT WILL NEVER TRUST AN APPLE UPDATE AGAIN

I have come back after some testing. I was the guy on the farm having 5GHz issues, of crashing and rebooting 880L.

Clean installs using fresh downloads and Diskmaker X below yielded the following results...

• Yosemite - Same problems
• Maveriks - Router's WiFi drops for all users when connecting to 5GHz (immediately), although MBP appears to be connected for 30 seconds. Router does not reboot this time, but takes 60 seconds or so to recover its wireless connection.

At this point, as 5GHz works for other devices I'm going to assume that I have a hardware compatibility issue between my 880L and 2014 MBP.

I will update my original post to avoid confusion.

My wifi started booting me off and sometimes disappearing altogether. I tried various software changes and reboots to no avail. Finally I looked at the number of wifi hubs listed under the wifi icon. Sometimes more than a dozen devices from my neighbors were present. I finally decided to try and make my wife "radio" more visible. I moved it up about 18 inches. Problem seems to have cleared up. I still have a ton of folks showing, but I've not been booted since.

After doing clean installs of Yosemite and Mavericks I have noticed something without giving one moments thought...until now. Sometimes we are so close and wrapped up in a situation or problem, we become to close to see the bigger picture. Here it is address as a pointed question:

Has anybody noticed when performing an Internet Recovery back to the OS X that shipped with their machine, that, the Mac's Hardware Inherent Wi-Fi driver performs flawlessly, without connection issues, slow downs or drop outs? Ah, Hah! Bet you didn't catch that one. My numerous Clean installs and Clean re-installs using both my 5 GHz and 2.4 GHz performs as advertised, absolutely fluid performance.....until....the evil OS X is installed. Apple, they're a card, eh? I have only had my Mini since August. Mavericks is back and Boot Camping Windows 7 Pro. I and my wife are going to use it now. I have reported to you all my methods and findings. I have reported my results to Apple Feedback.

"...and so I close, realizing that perhaps the ending, has not yet been written."

I failed to show my steps in previous post. Internet Recovery for Mavericks and Yosemite. Clean, clean install to test my previous post. These are the steps I used to show my results of Wi-Fi in Internet Recovery mode vs. OS X.

1. Backup all your personal data. You will be erasing your internal hd completely.

2. Shutdown. Power up hold Command + R. Using Disk Utility, Make sure your HD is one single partition GUID PARTITION TABLE formatted as Mac OS Extended (Journaled) named Macintosh HD. Erase using the Security Option of a single pass of zeros. Sit back.

3. After erase is complete, Shutdown. Disconnect everything except Monitor, USB SupureDrive and USB Keyboard. MacBook users just disconnect anything you have in the ports. MacBook users need to be plugged in to charger.

4. Power up using holding Option + Command + P + R. This resets NPRAM. The computer will boot to a flashing folder with a question mark. Shutdown.

5. This step is for my Mini. MacBook users refer to Apple Support Docs for Reset SMC Instructions. Unplug the power cord. Hold the power swith for 15 to 20 secs. Let go. Wait 5 to 10 secs. Plug in your computer. Your Mac is now void of all residual settings.

6. Power up holding Command + R. You will enter Internet Recovery. It will let you choose the Network to connect to via Wi-Fi. This is where I tested my 5 GHz band and my 2.4 Ghz band, Two separate Clean installs.

7. Recovery will download and you will choose Install a New Copy of OS X. follow screen prompts. " Installing OS X" finished. Computer will restart.

8. When the "Welcome"  screen appears. Shutdown holding power button.

9. Perform another SMC Reset. Now you will experience the fresh out-of-box feeling.

10. Power up and setup like you did for the first time. Mavericks is great. Yosemite takes a few hours, but, it shows the problems as address in this thread.

Note: That if anyone does this, your personal data must have already been backed up. Like I stated. I accomplished Internet Recovery logging into my 5 GHz and a separate Clean install using 2.4 GHz. The best I can tell, the Recovery Partitions System Config Files and .Plist files are overwritten by the OS X upon installation. Model specific SMC and NRPRAM instructions ca be found on the Apple Support website.

Take care, all.

My wifi has been cutting out randomly ever since I installed Yosemite. My wifi connection is via Time Capsule (2nd Gen). I did not have any wifi issues prior to the Yosemite install. I tried everything posted on various discussion boards and nothing worked. Including a clean install. Yesterday, I decided to try a new approach by resetting Time Capsule to it factory default settings (backup data on Time Capsule is not erased). I set everything up as a new network on 2.4 and 2.5 GHZ (Automatic). I am now happy to report that my wifi connectivity issues have been resolved.

Hello my friend

                          ok Yosemite the art of the empire of apple... your OSX  is corrupted   listen to me and you'll be up and running  i posted this post so ill copy and paste it here follow my direction and ignore the headline because its all related :

Ok here the deal straight from the creators of Apple .... Yosemite is corrupt !  As we all know downloading a new software product is a pain in the butt because. The anticipation to release it comes to quick before all the bugs are fixed.    I think Apple is designing stuff to make thinys wonderful but taking away things that made the apple lover forced to like a design they hate....

       1-       Ok beach ball slow down problems :    First of all you need to empty your cache .... NOTE NOTHING ELSE THAT STARTS WITH  (COM.APPLE)  only in the cache folder Is ok go to   Finder :  go:  computer  hold down option and click library you'll see a system of folders take the cache folder and drag it into the trash bin then delete it  that's all system junk...... Don't worry              

         2- Next step fixing a corrupted OX Yosemite that's making beach ball and slowdown .....   Power off your computer  hold down command -R.  Until your computer starts up  a box will appear asking a series of questions  click on the one that says install. OSX  press agree, add your Apple Id and let the system run its coarse:   Make dinner, do laundry, whatever but it takes time .... It will shut down and restart then an install will start and that take 30 minutes .... When all is done your system operating system is restored to your original state before you did all this without losing anything, plus your stem will be free from malware and your operating system will have all the new Yosemite bug fixes cured ......  DONT LET THIRD PARTY VENDORS TRICK YOU INTO DOWLOADING THERE SOFTWARE TO REMOVE AN UNWANTED PROGRAM JUST DROP AND DRAG IT YOUR TRASH THATS IT.......AND IF YOU FOLLOW THESES STEPS YOULL BE HAPPY TO KNOW THAT YOU DIDNT HAVE TO SPEND $100 of dollars for a technician to hold your computer in a shoppe DOWLOADING all your imprtant software and do a simple fix like I described.    Geek squad wanted to charge me $250 to come to me for diagnostics  and they also told me my hard drives going .... Obviously they know jack **** !   All in all feel free to send questions       Enjoy your faster malware free uncorrupted  operating system.    Peace

Tried this and it did not fix my slow/dropping wifi connection. The connection speed was fine for 5 minutes, then it was back to "beach ball slowdown"

Steve Jobs is truly dead. Without BLUETOOTH, I have no mouse or keyboard. I found an old corded Mouse, but don't have a corded keyboard.

So tired of Apple seeming more and more like Microsoft since Jobs got ill. (Got bad with Lion and everything since.)

Cordless land phones run on the 2.4 GHz bandwidth. Channel switchable on most models. Anyone made sure their 2.4 GHz cordless land phone is as far from the router as possible? Newer cordless land phones are on the 5.8 GHz bandwidth. I pulled the old school touch dial land phone out of the closet. If, say, a bunch of people in the neighborhood still use 2.4 GHz cordless land phones, there will be noise interference.

NOT SAYIN THIS IS A FIX! JUST AN ELIMINATION OF ANOTHER POSSIBILITY FOR SOME. Cleared up static on my cordless home phone. I'm sure my downloads from the internet will love me for it, too.

Hi John. 1st of all accept my belated wishes for the new year. And many thanks for all your good efforts.

Now about your suggestion above: I've posted about possible radio interference on the crowded 2.4 GHz band from all kinds of devices in this thread before, and others have too. USB3, Bluetooth, DECT phones, Microwave ovens, cell phones, babyphones, lots of wireless microphones and in-ear monitoring systems, and many, many others. Not the least of which: your neighbours' gear.

This, however, is not an issue typical to Yosemite.

Radio interference and bad reception are general WiFi issues which in fact belong in other threads.

And something else, pertaining to your previous posts. Which has been mentioned here before, but not with much emphasis. It is not the whole of Yosemite which is rotten. But only/ mainly DNS resolving of Bonjour networked devices. Perhaps due to Discoveryd, which must still contain a serious bug which mDNSResponder under Mavericks did not seem to have.

Only, at some Yosemite testing point mDNS rsponder was finally pulled (DevPreview 5?), because under Yosemite DP, mDNS responder showed the illness at stake here. Meaning, connection with the router's radio isn't lost intermittently, but some systems cannot resolve the DNS any more- intermittently. To remedy that, they have introduced Discoveryd, which seems not to have helped for some systems. That is the real issue at stake here, the only issue specific to Yosemite.

There have been reports of users solving this problem by replacing their discoveryd.plist with the mDNSResponder.plist (from Mavericks 10.9.5 or one of the Yosemite Developer Previews). Some of the latter are still around on the net. But I think they may be playing with fire here!

Some interesting background reading on the transition: https://coderwall.com/p/ylchfq/osx-yosemite-bonjour-mdnsresponder-problems

From this link a nice Terminal tip to check if your DNS responder has seized or not (even works on an ancient Snow Leopard Mac for me- for its ancient version of mDNS responder, that is):

To check the service is running, use:

ps aux | grep -i dns 

You should see /usr/sbin/Discoveryd running

By the way, read the link through carefully, and you may find some other forgotten solutions as well. Happy hunting!

Sorry, just trying to help unravel the big knot made up of various twine this here thread is, and trying to find the still knotted kind of twine relevant to this thread...

Hello and Best New Year Wishes to you. Thank you for the info and link. I, too, am guilty of not reading the history of this thread. You were right when you said "this has been a long haul". I am left with a bitter-sweet taste when I think that all is said and done, Yosemite will be strong and stable this year. Then, OMG! In fall or spring at some point people will hit the Upgrade to "----" OS X button just because it's flashing and new looking. Sorry, just trying to make a smile. I will do further study based on the links you and others have posted as well. I have seen looking back, that some of the people who posted in this thread were invited by Apple for Beta testing and are not posting here as such. Good for them. They may be monitoring this thread for further Beta testing of the next public released Yosemite update. In all fairness, Yosemite is the OS X to propel The Macintosh and Apple to the next level. I do, on occasion, sit back and try to get a grip on that fact alone. Like was once said: "one thing, we need to do, is keep, talking." I'll keep hunting. Thanks and keep the good info coming. Good investigative posting on your part!

I have a MacBook Pro Retina 13" that I purchased in 2013 and am having all the same problems I'm reading on this thread.  My WIFI is completely undependable on 5 or 2.5, my machine is slow enough that I have to wait sometimes for the keystrokes to appear I type so far ahead.  It is as if I have malware on my Mac.  I switched to Mac with this computer and am at a loss for utilities such as defrag and memory optimization that I should be doing to keep it efficient, but I have read many cautions about MacKeeper so I have stayed away from it.  I though my machine was "infected" with something, but after reading this thread, I now believe it's the Yosemite upgrade and I have had a lot of trouble with some of the individual apps (even Apple) as well, such as the Calendar.  iCal seems to disregard the times and appointments I put in sometimes completely.  I've also read about the O/S possibly taking up more than it should on memory and causing issues.  Not sure what to do.

Thanks for the tip carlfromsaddle brook.  I am going to try this as it seems to be the issues I am hitting.  Certainly not good enough with computers to do these things without good instructions as you supply.    Chad from Austin.

Hey guys, I may have found 1 right strand of forgotten twine on a sister thread:No internet connection after installing yosemite

Especially read the post of csukale

Seems to me some of you even after having performed a clean install of Yosemite, but having migrated the rest from an older system may still have mDNSResponder  launched concurrently with Discoveryd. They will clash!

Quote csukale/ formatting mine:

Hey could you guys do me a favor and check whether or not there's 2 files in your /System/Library/LaunchDaemons folder named mDSNResponder.plist and mDNSResponder_helper.plist?

If you find said files you you then maybe check your log files and see if you have any error messages regarding mDNSResponder in there? mDNSResponder got replaced by discoveryd and I think it therefor should not be launched anymore. For some reason it was still in my LaunchDaemons folder though. I did a clean install on another Mac and those files were not there. Said Mac didn't have any problems with the internet connection.

If you cannot find those files, start a Terminal session and type:

ps aux | grep -i dns

By this you might detect Discoveryd and mDNS responder running concurrently as well. Do so immediately after a restart, when your internet is still working. Because if one of both have crashed/ stalled/ seized, they will disappear from the list.

If mDNSResponder is still found active in some way on your Yosemite, move said mDSNResponder.plist and mDNSResponder_helper.plist to the desktop and restart. If all is well afterwards, you may thrash both files.

You may also want to post an Etrecheck report, of which we have seen very little in this thread.

And thank you for this forgotten gem, csukale
