Wifi slow on macbook air

Hi all,
I bought a new macbook air less than 3 months ago and theres something wrong with the wifi.
I brought it to the mac store and they ran a diagnostics they found nothing wrong with the wifi but one of the tech guys found a problem with safari and said he resolved the problem.
I am using it now and its like using a dial-up connection.... so slow!!!!!!! I've used chrome and other apps to see if there any quicker and there not so it seems to be a problem with the macbook.
Just wanted to put this up in case anybody has had the same problem and resolved it because the guys in the store didnt fix it and its an hour from my house to the nearest store.
Thanks,
Ross

Yosemite slow on Macbook Air

Help! Seriously....
I updated to Yosemite the other day and since then my Macbook is extremely slow...
It is really annoying, especially because I have no clue what the reason could be.
I would really appreciate if anyone has an idea how to fix this.
Apple doesn´t seem to know the answer! (What a let down...)
Thank you very much for taking your time!
Some of the problems:
+ The fan is running much more often now
+ MacBook gets very warm
+ Battery drain is extremely high
+ Animations and scrolling inside OS not fluent anymore
I have already tried the following:
+ new install
+ verify disk permissions
+ SMC-Reset
+ PRAM Reset (Cmd+P+R)
Here comes my report, I really hope anyone can help me with that.
I am really disappointed of Apple... What a let down!

Had the same problem, finally realized that the FileVault Encryption was struck at 19%. Speed back up to normal after I disabled FileVault using terminal command - sudo fdesetup diable
To check whether the FileVault is the culprit, go to System Preferences --> Security & Privacy --> FileVault to see if encryption is in progress.. For me the blue bar was less than a quarter with status 'estimating time remaining'..
Then open Terminal and type in: sudo fdesetup disable
It will then ask for the admin password (to be it asked twice), then it was disabled... Back to normal life again..
Here is my terminal log for reference:

Macbook pro 2012 is slower than macbook air 2012

I have found that my macbook pro 2012 13" (non retina) is slower than macbook air 13" my co-workers own. all macbooks have same softwares and versions.
Macbook pro has better processor but Macbook Air is faster. I guess it is because of Hard drive in pro vs SSD in Air. so my questions are:
Does anyone have a same exprience?
and if I change my HDD to SSD can i beat macbook pro in speed?
waiting for your quick answers because I am feeling bad these days.
Thanks in advance

How to fix my slow wifi on my Macbook Air?

Hello!
I have been having issues with wifi on my late 2010 Macbook Air. I have OSX 10.9.4. I notice that my wireless issues are fine if I'm within 10 feet from my wireless router. If I boot my same MBA using Windows, I have no issues what so ever and can even go outside and have great speeds. I have tried different browsers on the mac side with no change, I have also tried different networks with no change. I have used my fiancé's MBP and she has great connectivity throughout the house. So, I have ruled out a network issue and a hardware issue as the internet is fine on my MBA when using the windows side.
I do have to mention that my screen was replaced a little over two years ago and did read that some people who had repairs done to their laptops sometimes found that their antennae was not properly hooked back up, but again, I'm ruling this out because I believe I would still have connectivity issues on the windows side of my MBA?
I have done some research here and tried disabling BT with no luck. I also tried fixed 2.4 GHz and 5.0 GHz channels with no luck either. Also, in my research, I found a neat app called EtreCheck and have posted those results below. Any tips or trouble shooting I can try from here would be greatly appreciated!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Apple AirPort WiFi connects to MacBook Air and iPad but not iPod Touch

I got my iPod touch 4th Gen in December for xmas and the wifi has worked perfectly fine until about a week ago only on my ipod, it just says 'Unable to Connect' everytime I try and connect but works on my MacBook Air and iPad
It's a WPA2 Personal security
I've tried all the suggestions on the Apple Support page, including resetting the network settings

Does the iPod connect to other networks?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on the router
- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

OS X Yosemite is very slow on Macbook Air 2011

After upgrading to 10.10 my 2011 11-inch Macbook Air became very slow. Sometimes it even freezes for about 5 seconds. I've tried to reinstall system 2 times but it didn't help. So the problem i think is in 10.10 itself. Right now I installed 10.9 because 10.10 is unusable. Does anybody experiencing such problems with Yosemite on 2011 Macbook Air.

When you have the problem, note the exact time: hour, minute, second.
These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
The title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
Each message in the log begins with the date and time when it was entered. Scroll back to the time you noted above.
Select the messages entered from then until the end of the episode, or until they start to repeat, whichever comes first.
Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
The log contains a vast amount of information, almost all of it useless for solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.

Wifi problems. Macbook Air 2012

Hi!
I have no problem connecting to my internet at home, but everytime, if my computer goes to "sleep", or if I pull the screen down, I am no longer connected to the internet. The problem is that it will not connect automatic. If I bring this computer to some friends, it will recognize the internet, and connect automatic.
I dont think it has anything to do with my internet, cause both my Iphone and Ipad recognize the internet.
Best Regards
Roar

O
I had the excact same issue, I have now restored to OSX 10.8.1 rather than update to 10.8.2? downside is I cannot use iPhoto because it requires 10.8.2 to install
Strange thing is when i updated to 10.8.2 and logged in as a guest user i had no internet problems, but as soon as I switched back to my account login the wifi issues came back?
I even spent 2 hours on the phone to my internet service provider thinking it was my router giving up.
It was only through luck that i picked up on the fact that it didnt cause issues before i updated, but only after the update did the issue raise its head.
Im a loyal apple user, I also sell apple products through a reseller bar inside the store I work, but im starting to loose faith.
Lets hope this is a bigger issue than just a handful of users, that way apple may get a fix out for this
( Fingers crossed)

My macbook air became too slow, my macbook air became too slow

Hi dear Mac users
My macbook air became very slow.... is it because I have too many pics? or can I do some type of organization that I never did before?

Saying it is running slow is a bit vague, can you be more specific about when/how it is running slow (i.e. what tasks/programs/actions are you undertaking when it runs slow?)
It is doubtful that you have so many pics on your Air that it is running slow because of that, you'd have to have 10s of thousands of pictures to even come close to filling up the storage capacity of a 128 SSD (which I'm just guessing you have.)
By "organization" I'm assuming you're referring either to doing a disk defrag (not necessary on Mac's, especially an SSD driven Air due to the nature of SSD read/write capabilites,) or you're referring to how you have your pictures arranged in files on your storage drive, which isn't likely to be the culprit, either.
Given the lack of knowledge I'm going to guess that if you're noticing the slowness during normal operations it is probably going to be due to having too many CPU-intensive apps running at the same time (running flash based webpages is a major CPU hog as well as some high-res video or 3D apps/games.)
Let us know more and I'm sure someone here can help you figure it out, though.
Cheers!

Yosemite slowing down macbook air performance

Ever since upgrading to yosemite, my 2011 macbook air 11' has been very noticeably sluggish compared to how it was with mavericks. At first i thought it might be from some conflicts from the previous OS, so I did a completely fresh install with yosemite, but it's still dragging and sluggish, especially with any kind of graphics intensive process. I know the air isn't supposed to be a marvel at graphics performance, but I never had these performance issues with mavericks.
Is yosemite just too resource heavy for my macbook air? I wonder if I'd just be better off going back to mavericks. However, if there's some kind of settings I need to adjust, I'd be happy to experiment. I've already tried the 'reduce transparency' trick, but it didn't do much (not that I noticed anyways).

Gatekeeper is described here: OS X: About Gatekeeper - Apple Support. It is only one defense to protect you from inadvertently installing malware, and an effective defense does not rely upon only one method.
... I can use software that isn't officially "identified" by apple, even though it is trusted.
Apple's philosophy is such that a Mac user with Admin privileges always has control over what he or she installs. As I wrote Gatekeeper will serve to protect you against inadvertently installing malware, including the adware that is affecting your Mac. Adware does not get installed on its own - it requires your explicit permission, which you provided by supplying your Admin name and password. When that dialog appears, it should be expected, not a surprise, and its implications should be clearly understood. By providing your credentials OS X concludes you know what you're doing and the reason you're doing it. Determining the "trusted" aspect of software thereby falls to you.
In your case, by choosing the "anywhere" option you effectively circumvented this basic OS X security feature.
The problem with adware is that it relies upon deception to convince you that it's legitimate software offered for some beneficial purpose, when in fact all it will do is interfere with your normal activity and possibly crash your Mac.
Is there anything I can do to possibly identify which apps may be slowing my system down?
Yes, although you installed quite a number of them. For troubleshooting, read below the line that follows the end of this post.
An EtreCheck report generated on a Mac as it ships from Apple will show no entries under Kernel Extensions, Launch Agents, User Launch Agents, Safari Extensions, 3rd Party Preference Panes, etc. Everything that appears under those headings is there because you installed them. As I wrote it's a user's responsibility to understand the specific benefits they are intended to convey, the effects they will have, and the means of uninstalling them should they result in unacceptable performance - which was your original complaint.
It's also possible that the slowdowns are not caused by software, but given the extent to which your system has been modified, hardware failure is less likely than incompatible or poorly implemented software.
... anything that isn't officially "identified" by apple is adware?
Although OS X incorporates specific prohibitions against installing common malware, they can hardly attempt to classify specific user-installed modifications as adware. The only certain way to do that would be to prevent user-installed system modifications altogether, in the same manner as they do with iOS (iPads and iPhones).
Adware's appearance changes approximately every day. Their pathetic developers are desperate to change its appearance in an effort to continue their deceptive tactics, and a simple change of a file name precludes a reliable automated means of intercepting it. That's the reason it's incumbent upon Mac users to educate themselves about its appearance so that they are not so easily gulled into installing some junk. Gatekeeper merely helps you understand that's what you'd be doing.
Back up your Mac if you have not already done so. To learn how to to that read Mac Basics: Time Machine backs up your Mac - Apple Support.
If your Mac is momentarily unresponsive, consider the following.
Launch the Console app - it is in your Utilities folder. You can find it by selecting Utilities from the Finder's Go menu.
If the log list column on the left is not already displayed, show the log list by selecting Show Log List from Console's View menu. Select Show Toolbar if it is not already shown.
Locate system.log in the list and select it. Many date and time-stamped entries will appear, hundreds of them, and you must find the entries relevant to your Mac's problem.
To do that click the Clear Display button in the Toolbar. All previously displayed log entries will be disappear.
Next: Perform whatever actions cause the Mac to exhibit the slow behavior. If the problem is caused by errors logged by the system, the Console window will show them being recorded in system.log.
One or more of them, along with their time stamps, may reveal the reason for the problem you describe.
Copy and paste those log entries in a reply. If hundreds of the same repetitive messages appear, please edit them before posting. There should be no need for more than a few log entries.
Most of the entries will be cryptic but will contain information you might consider personal such as your Mac's name. If you do not want that information to appear, delete or obscure it when posting your reply. Leave enough information so that the entries can be deciphered.

Why does safari is very slow on MacBook Air?, why does safari is very slow on MacBook Air?, why does safari is very slow on MacBook Air?, why does safari is very slow on MacBook Air?, why does safari is very slow on MacBook Air?

Hello. I am using MacBook Air. Safari is very slow and it doesn't open many websites. for instance: dizi-mag.com . please help me

Please answer as many of the following questions as you can. You may already have answered some of them.
1. Have you restarted your router and broadband modem since you first noticed the problem? If the answer is no, do that now and see whether there's any change.
2. Are any other web browsers installed, and are they also slow?
3. What about other Internet applications, such as iTunes and the App Store?
4. Are there any other devices on the same network that can browse the Web, and are they also slow?
5. If you can test Safari on another network, is it slow there too?
6. If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference?

Typical WiFi speeds for Macbook Airs

Hello,
I'll admit right away that I have a bit of an obsession with WiFi speeds, it's never fast enough for me, so I spent an inordinate amount of time trying to squeeze the best speed I can out of my mid-2012 Air. I'm hoping to find like-minded people here that are as obsessive as I am.
Right out of the bat, I know the Air has a 2x2 antenna, so there are limits to how much you will get out of a 802.11n network. I find due to where I live, only 5Ghz is a realistic option. It also allows for 40hz channels, so it does help. I use iperf for most of my testing.
As far as I can tell, theoretical speed for the Macbook Air Mid-2012 is 300mbps. I'm easily getting close to but never above 200mbps on an ASUS RT-N66U when in the same room. As far as I can tell, this is actually on the high side from various posts on the Internet. As soon as I go upstairs to my bedroom that sits right above the router, speed drops to at best 40mbps. This is consistent on both a Retina iPad Mini and my Macbook Air. Just goes to show what an impact a wall can have on the 5Ghz band.
So what I'm looking for are typical experiences from other users as well as from people who have made the jump to 802.11ac.

Also, not sure if it's just me, but the image in the orignal post is no longer showing up, so I'm posting it again here

Kernel_task slows down MacBook Air

Every now & then my MacBook Air slow WAY down.
Activity Monitor shows that a process called kernal_task is using 144.6% of my CPU!!!

Can someone tell me what is going on?
And how to STOP it?

Keep after Apple to fix the issue. You may need a new logic board.

IPhone 4s won't connect to Wifi or my Macbook Air

I have an iPhone 4s (iOS 7.1 software, phone says it is up-to-date) and it is not recognized by my Macbook Air (OS X version 10.9.2, computer says it is also up-to-date). I switched computers in January, from a Macbook Pro to a Macbook Air, but did not transfer any iTunes information onto the Macbook Air from the Pro. I've avoided connecting my phone to iTunes on the Air because I would lose my music on my phone (which I have backed up on the Pro). I don't know if that has anything to do with the problem, figured it was worth mentioning. My iPhone also stopped connecting to Wifi (it is greyed out), causing me to use a lot of data. How do I fix these two issues?

at this very moment, all of apple's servers are a little over loaded, so i wouldn't be surorised if you have trouble baking up to iclou right now. with that being said, go a head and try restting your network settings under Settings > General >Reset > Reset Network Settings

How to i connect to internet without wifi on my macbook air

Hi
i have a MacBook Air and i am visiting with my parents who do not have WiFi ....
how can i connect ?
as you know, there is no Ethernet Port on the MacBook Air
can i do this remotely through their PCs ?
thanks

If they have PCs with wi-fi capability. Most/all Windows laptops will but many Windows desktops do not. The following instructions may help (both are for Windows 7 so you may have to search if that isn't what they have):

Another option is an ethernet adapter if you have time to obtain one:

Problems with WiFi between my Macbook Air and Iphone 6

I have a Macbook Air (I purchased it around Dec. 2013)
My problem has been happening lately the past few months.
If my iphone 6 is connected to my Wifi here at home and it is plugged into my Macbook Air, the internet on my Macbook stops working.
I have to turn the Wifi off on my phone, for my macbook to regain it's connectivity and begin to work.
My hotspot is not turned on on my phone, or anything like that to prevent my Wifi from connecting on my Mac, but this problem happens EVERY TIME my phone is connected to my macbook.
Is this happening with anyone else? Is there something I'm probably overlooking?
Please help.
MacBook Air (13-inch, Mid 2013)
1.3 GHz Intel Core i5
4 GB 1600 MHz DDR3
OS X ver. 10.10.2
iPhone 6, 64GB, Gold (Verizon)

Update:
So just that quick! I updated to iOS 8.2 and It seems like the problem has went away.
