Awesome machines other than the lack of upgrade and battery replacement options though. Re Same goes for unused preference files imho. My main culprit was GeekTool. A calendar geeklet I was using was set to refresh every 0 seconds! As soon as I changed it to every seconds, the machine was suddenly snappy again.
On my iMac, you can hear the hard disk running constantly. This is a great and helpful article, but 9 might be better off as 1 or 2 since this happens no matter what and can be the most annoying. Do a fresh install i instead of upgrade, if you have a rpm hardrive replace with a rpm , save your data songs, videos, etc on separate partition and avoid as possible install too much programs that runs services on background.
I think the OS itself has performance issues. And in case you think my Internet coonexion is to blame, 50 of these 88s we had the default Safari list of recent items, ie it had not even been as far as clearing the screen. During thaat time, trying to switch input languages by clicking on the little flag caused no visible response for 12s. Snow Leopard was a really lean and mean OS. Mountain Lion, like Lion, is a real pain to use. Tried on three different Macs with the same result. This though, you do not know. Google it. Rebooted router. Logged back into MacBook — hey presto — problem solved and all working without interruption now even after several test restarts over the last 24hours ;-.
I upgraded my Mac Pro late from Mavericks no issues were noted to Yosemite as soon as it came out.

I was using it wired and sparingly, so I did not notice the Web browsing issues until I decided to switch my primary machine to the Mac Pro from my MacBook Pro 2. I was experiencing slow internet speeds wired and Ethernet and discovered that the wiring in my home was generating crosstalk and lots of temporary errors. At the same time TWC upgraded my speed to Mbps contributed to the issue. So I had all the connections redone. I can load the same page on my MacBook Pro in 2 seconds where it takes almost a minute on my Mac Pro. My opinion is that the migration process messed up a lot of system wide settings.
I have two other systems to migrate and I do not need that aggravation. Well, this solved another problem as well. My Apple TV stopped working. I have re-copied the removed files to their original place, and it works again. I tried most of these with no luck and I have tried the new update to Yosemite. It has been day 3 with NO problems.
I have cable Xfiniti internet connected to the Airport. Likewise with the iPhone 6, getting download speeds of Mbps. Nothing worked — until I switched from the 5Ghz network to the 2. I think one of you above suggested this fix: Step 1 in the link above worked for me. At least it seems to have solved my network problems when reading email in Firefox.
Resolving Mail Problems After OS X 10.10.4 Update
Yes, the Firefox browser loads my gmail quickly. But, when I attach a large file, the attachment loading times out. I went through this list about 2 weeks ago and it did not seem to help. Then my computer started getting slower and slower and then the internet did not work on anything except chome. Turns out I unloaded the discoveryd.
Any reloaded it and things are bag to normal. I cannot test my wifi yet as I do not have it but it atleast fixed my ethernet to be able to dl faster and able to get other apps to connect to the internet. Yes, drill. To get up and running I drilled through the wall and ran a hardwire ethernet cable to the AE. Then, one more thing… I am on the 2. Much better performance. Thank you, thank you, thank you!
I tried everything I could think of with no success. Then I found this page, followed the instructions, and it worked! Your help is much appreciated. While trying to configure my time capsule as a wi-fi bridge, I completely lost wi-fi configuration on my macbook air v The instructions in the very first section: Thank so much!
The first suggestion worked for me!
I fought with this all day yesterday thinking it was my internet service provider but finally realized duh that I could use my devices on wi-fi. I linked to your site from another that came up when I googled my error message. Thank you soooooo much for clear and concise directions! What a disgrace with Yosemite. Wi-fi on MB A After trying numerous things, turning off blutooth appears to have done the trick for me — for now …. The cause of the wi-fi problems was the Bluetooth. By disabling it I went to Internet at the max speed ever.
Wifi is connected, but randomly web sites failed to load. Web Page sits there waiting. After a few minutes or manually turning wifi off and back on, the page will display and everything works fine. Apple is aware of the problem and will be sending the tech brief to me. Reset the SMC: Hold the Shift, Control, and Option keys on the left-side of your keyboard and press the power button.
Release all keys. Running Yosemite I used time machine to roll back to a previous point in time and restored the SystemConfiguration Folder and then performed the SMC reset. Everything seems to be working great now. No disconnects and fast internet access. After 24 hours, I believe this problem has been fixed. My MBPr is running fine now for 2 days.
Before switching my router to WPA2 personal my wifi speed would drop to max 2Mb after a few hours max. After weeks of losing wifi connections; implementing various short term fixes, and a number of calls to Apple Support again short term solutions , I was bumped up to a Senior Tech. Here is what we did:. Backed up Time Machine on to external disk, and as a double backstop, copied a number of critical files containing passwords, receipts and application codewords first to a file on Desktop, and then to a portable external disk. Then did a clean reinstall Yosemite as a shell. The only functioning additions were a connection for Safari and Mail.
This setup was given a two day test, and worked flawlessly. The plan after two days was to bring applications etc back out of Time Machine; but I was so pleased with efficiency of Yosemite, I opted to download replacements for the applications I currently use, and ditch all the detritus that had built up over the years and which was now never — or hardly ever — used. One item they could not return was Keychain; but I had the information elsewhere so ok.

And what did that all cost? Not a penny. Even though my AppleCare subscription had run its course. Apple is providing 30 days free telephone support for Yosemite wifi problems; or at least was last week when I finally signed off. And when it works, Safari in Yosemite is brilliant. I have a brand spanking new MBP Retina 2. It came with Yosemite preinstalled. It works relatively well on my home wifi with my Airport Extreme.
On my work network I get kicked off the network every minute or so. Option one worked for me and was easy to do. The only thing I would add to the fix is that if you have wifi printing, reboot the printer after you have confirmed that the computer is working on wifi. So not to be stupid, but in step one do you need to delete those folders after backing them up and before rebooting your computer? I just downloaded the yosemite Update to OSX After trying everything that last DNS change did it!
I disabled icloud handout and that fixed it, nothing else worked. It is in preferences, general tab. After upgrading to OS X Yosemite Using solution 2 new network location with custom MTU set to cleared up the problems and dramatically improved the speed and reliability of my ftp connections. This will be my last apple product. Thank you SO much! Your advice worked so well, I just wish I would have been able to access it sooner, no WiFi the week of finals is very frustrating! Ive tried most of the suggested solutions http: I contacted Apple support via chat today and the tech provided the following solution which seems to have resolved the problem for me:.
I did this nearly 24 hours ago and the connection to my local wifi network has been stable for almost 24 hours. Previously this have been dropping at least 3 or 4 times an hour. It does work like a charm now. I think the 1st fix worked!

The system preferences settings were immediately different after the reboot. FYI I did not have all the files you mentioned. I installed Yosemite and not able to connect wirelessly or ethernet. Apple fix failed -reinstalled, failed. All ready to go back to lion when a new person at Apple said unplug from the mains, remove all cables and so reset the systems control manager. Ie when all unplugged hold start button for five seconds, then replug and reboot Yosemite picked up all peripheral fine including router. I found one that actually worked.
I was also having the same issues with my iPad2 ever since upgrading to iOS8, and this seems to have fixed that problem as well. After 30 minutes of trying everything in this article, to no avail. I have unrolled an old cat5 cable and plugged it in and disabled wifi. Works great now, welcome to the 21st century. First Option, works greatly. Than you man. Thank you! I said the first option helps me, but it just happens for a while. About 1 hour working ;. Now i tried to Reset SMC, seems working greatly.
I will wait Apple fix that. After i installed Yosemite on my 13inch MacBook Pro, the wifi would often go off by itself. After restarting the computer a few times it would come on, but then go off again after a while. At first i figured my wifi hardware was just faulty and got it replaced with another, but the same problem occurred with the new hardware as well. I even restored my computer to factory settings running on the original OS X Lion and still the same problem. Does anyone have any suggestions? I tried everything too. Tried rebooting, redoing commands… Nothing works.
I have been having wifi issues like everyone else except my wifi will not even connect. Could that be the issue? Thanks for the info. I hope Apple will fix it with a update to Yosemite soon. My wifi-connection at home is suddenly unstable. This means WEP security why is that the default? I kept meaning to change it, but the trouble was just a bit too much to deal with until this came along. Quick note: I checked the MBP wifi connectivity on my work network and it was perfect.
Immediate connection, no drops. My fix was simply to access the router and update to WPA security. Bonus for us is our older iMac 7,1 running After many months of just resetting my router Telstra Cable Netgear , I rang Telstra to complain as my mac was working consistently on my 4g device.
I got a upgraded modem from Telstra and thought my problems was solved as i didnt have issues but within 24 hours i started getting the same issues. I have been running tests standalone to see how often it was disconnecting etc.
Fix Wi-Fi Problems in OS X Yosemite
Tried various browsers etc. Once this was turned off My mac has been performing great. I reverted my firewall back to medium settings and confirmed the IP Port scanning option has caused the issues. My Previous router may have been blocking these options by default and unable to change that option. Tried a number of fixes suggested out there. Obviously not something I want the boss to live with forever, but thankfully it only needs to be run again after reboot.
But the one worked fine for 2 days before having DNS issues. Still trying to determine if some computer setting during Migration Assistant hosed it or it is a bigger Yosemite issue. Clearly Apple QA was a bit lax…. Deselecting it always results in beachball and you need to cold book and restart. End result is a second user account and the setup the second time through skips FileVault…thankfully. Pretty sloppy IMHO. Since there is such a big bug for Yosemite, why is Apple still releasing it?! I think you missed one of the simplest fixes for Wi-fi problems: Turn off IPv6.
ISPs have yet to iron out the bugs in their implementations, and they may also require settings changes that are undocumented. CenturyLink, for instance, has been rolling out IPv6 over the past few months, and I had to turn it off to keep my wife connected in Mavericks. It was an instant fix. Two computers in our house; two different sets of problems. All resolved from online info not provided by Apple.
This Yosemite update: Resolves an issue that might cause Wi-Fi to disconnect Resolves an issue that might cause web pages to load slowly. Thank you so much for publishing. I was sooo frustrated for sooo long!! I dowloaded Yosemite I never thought I am going to say this after all these years: Well, Apple, you have just reached the same level.
I am having trouble with wifi after upgrading OS from I was using this wifi router last 1 year without any trouble but now its not working. Can any one help me? I follow all the steps of trouble shooting mentioned in apple website. I have 2 hotspoots at home. To one it does not connect at all. Toi the other it connects but every 5 min or so the internet connection is down alltouigh the iMac is connected to the hotspot. After closing and opening wi-fi it works again for a few minutes. Thank you so much!!! I thought I was going to go crazy. The very first tip on this page worked for me!
Thanks again! First tips worked like a charm! Never experienced wifi problems until All solved now! I had no problems before the I wait for the connection to be stable a couple of minutes should do it then turn Bluetooth back on and the connection holds. After upgrading my MacBook Pro to Thanks for the many suggestions, tried pretty much all of them and none seemed to work for me. Have finally taken the step to Restore to Shame on you Apple for not testing Yosemite thoroughly and doubly so for not fixing it after two upgrades.
I tried all of the things above and was still having problems with two iMacs and a MacBook Pro. Then I looked at the BT site and found what I think is the answer. The Macs using Yosemite seem to get confused and lose Wifi while my iPhone and iPad were quite happy. I disabled the 5Ghz band and everything went back to normal. Currently the Macbook Pro is on 5 while the rest of the house is on 2. Fingers crossed……. Like Graham I also have changed to BT Broadband, but strangely the problem arose months after that change too.
What did the trick in my case was after point 1, 2 and smc reset did some, but the bluetooth was still interfering, was to do a HD disk verification and repair with disk utility. Now running smoothly even 1. I have had this problem for a while with my Mac Mini. Then I realized that at the same time my wi-fi connection drops, sometimes my bluetooth mouse also disconnect. I guessed my problem was due to interference between wifi and bluetooth and changed my wifi channel.
Thank you so much fixed my wifi issue with the step: Thank you so much, I never had wifi issues with Yosemite until the In addition to my previous comment. Very important, there is one file that may be missing for some people in the list that they say to delete or move to folder. Replace that missing file with the file named com. It works… My wifi works now! Thank you guys again! As soon as I go to add the new network location it opens a screen different to yours which says that the cable is unplugged.
The ISP connection was ok, but not the internet or the server connection. I was loosing my mind. So thanks a lot. OS X Yosemite is the most unstable unpredictable unusable operating system ever released for Mac. Complain to Apple, if you just bought your Mac you are under warranty and can get a replacement, free support, etc. Hello, I brought a new macbook pro with Yosemite already installed… I have had the laptop for a week now and I have an odd problem..
The wifi works fine but… When I try to use a ftp program the connection which it is trying to make to the ftp server times out or shows blank files on the ftp server … however if I plug the ethernet cable in via a usb connector apple brand it works fine, I see all the files… this really is a pain in butt… anyone had this problem? Did you manage to resolve it? I am so fed up with slow internet browsing after up[downgrade]grading to Yosemite.
Will try and report back. My first and last apple product. I mean ever ever! Each update gets it worse on my MacMini Late Some times it works but then after a few days it just dies miserably again. Before I would time out when trying to connect. I have tried so many different things for so long that my frustration level got to a hammer point I want to hammer my Mac to pieces. It is important to congratulate Apple for their effort! To my great surprise, it worked! And continued to work, even when I turned bluetooth back on!
I have my first MacBook and I am not happy. It is a 15 inch. I was alerted to this great update Yosemite and so I upgraded and everything was running just fine. I jump into my bed not literally and I start streaming Netflix. This is when my nightmare happened. My WiFi just went out. It says no hardware detected. Any help would be appreciated.
Since I have connected the cable as well the wifi connection no longer drops. However my MacBook Air, although fine at home, if I take it to work and connect it to their public wifi powered by the cloud my macbook air will drop connection every 10 mins. The Macbook stays connected without problems in both locations. Possibly why some people are experiencing these problems and others are not. Yes, I was thinking the same thing.
But if I access the Internet using my phone as a hotspot, the MacMini surfs fine. I tried to re-install my macbook pro back to snow leopard and everything just work fine even on the 5 ghz wifi access. Yosimite is crap. If steve jobs was still alive he would kill himself if his internet drops every 5 minutes. Turn it off in preferences and problem solved. I hate you apple……. Brand new Macbook Pro wifi dropping out intermittently and upon wake from sleep and startup.
When dragging the files to a new folder on the desktop com. Thank you so much! Not everyone running Yosemite on a Mac is having these intermittent WiFi problems, and some people report that when they use their Mac on a different router, the WiFi works fine. Could a lot of the WiFi problems reported actually be a problem with compatibility between particular brands of router and their firmware and something particular about Intel-based computers? As I understand it, this is meant to save power by putting the router into a dozing state when there is no demand for data, but the computer is unable to wake the router up.
Perhaps this is because there is a constant stream of data, so no chance for the router to doze off. A lot of people report WiFi drops out when waking their Mac from sleep — the router is also going to be asleep though. This is just an idea. Any thoughts? Signs so far are good. And it is not a coincidence that Apple has released every version of OS X Yosemite with a wi-fi fix included, it is a software driven problem. But to reiterate, not everyone using Yosemite has intermittent WiFi. And not everybody with intermittent WiFi is using a Mac. So while Yosemite might be partly responsible, there must be another variable at work, perhaps the way Yosemite deals with power saving modes on certain routers which seems to be a cause of intermittent WiFi on Windows laptops.
If you are experiencing trouble with Wi-Fi connections in OS X Yosemite, you should update to the newest version of system software available. Currently that is OS X I stumbled across the solution while looking for a firmware update for my router. Not a bad setting to use in an Internet cafe, bloody daft at home. I upgraded my macbook pro late edition from Maverick to Yosemite Oddly enough, it works flawlessly with the Cisco WAP at work.
Needless to say, no such problems running previous versions of OS X, with these three home routers. I was online working on a paper when my internet froze durig a video. I closed safari and turned my wifi off bc sometimes this helps. Out of nowhere, I had a new issue. After login not before , the Wi-Fi app would fail to load properly, resulting in a yellow indicator for the WiFi in the network settings.
This is true for all users. However, in Recovery mode or in the first login selection screen after reboot, the WiFi was still working. Long story short: I had to reinstall the OS after erasing the HD from recovery. Then, I applied the full time machine backup. Everything works as before now.
Gmail's IMAP Wackiness
First option worked for me: Thanks a bunch! I did not find the identification plist so i just moved the others to a folder on the desktop and then deleted them. I bought a macbook pro new from Apple April Got it home, it worked okay for a day, then it started logging off every few minutes in Safari. My iPhone 6, iPad, apple TV all worked fin. Thought for sure it was the Macbook.
An Apple junkie friend insisted that I look at my router. It had been on just AES. I also moved from 2. Turns out, also had n-band off. Made these adjustments and the Macbook is doing great now! I was certain that it was the macbook, but the router is probably worth a look even if it seems like not. Maybe the Yosemite is less backward compatible with older router settings than other software? I can take my MacBook to my local cafe and WiFi is fine. I thought maybe it was something to do with WMM settings, so I disabled these, but after early good signs, the problems returned.
Just a word on my router Thomson TCW But, again, are these WiFi problems partly down to particular routers and not solely about Yosemite? What routers are people using when the Mac has no Wifi problems, and what routers are people using when they do have problems?
Method 1 – Reset a Lost Mac OS X Password with Recovery Mode
I found that the later Netgear N works fine. Pity that people have to fork out more money to replace a perfectly good router that works fine with Mountain Lion. The trouble it took to find out what was going on is not what I expect from Apple. I switched from PC because Mac was a lot better. My son has now, after 5 years on a Mac, switched back to PC. Pierre, it could simply be that a setting on your Billion router was causing the problem, not Yosemite.
Ever since I disabled this setting on the router, my Internet has worked flawlessly. Your WiFi has got better — what variable did you change? The router. Suggests that your router was the source of the problem, not your Mac. Re Option 1. I was pretty giddy when I found this — figuring that was the issue. Then I checked another one of my machines and the file in question is not there either….. This solution worked for me 13inch MacBook Air upgraded to Mavericks:. Open Finder 2. Restart your Mac. I bought a desktop mac in January my first mac. OS X Yosemite with retina, etc.
Worked fine until a couple of weeks ago. The wifi connection keeps dropping off from normal to nothing. And I mean constantly dropping off, several times a day. I tried some of the fixes. More fool, me. Call the offiical Apple Support, you have a 1 year warranty. Complaining about your problems on the internet is not going to solve it for you. You can try the solutions in this article, they work for some people, but not for everyone. Just received this error on my brand new MacBook, seemingly without reason, after a reboot.
Deleted the plists as you suggested and voila, all is well again. OMG, thank you! Option 2 really solved my Wifi issue on my new Macbook which was just done data migration from my old one. I have a Mac Mini new out of the box Yosemite I am not a techie. I do not understand why or how but it does work now. I spent time with Apple and found that the problem was on the 2. It was not a problem for a 5 gHz network. I have a dual band router. The solution was to open the advance Bluetooth settings and disable the first option: Open bluetooth assistant at startup if no is detected.
I am not sure why, but apparently it keeps looking for a keyboard, even after starting up. Did this solve your problem? Yes No. Sorry this didn't help. Skip to main content. Site Feedback.
