Still: Macbook Air 2013 Wifi Issues On Wake-Up (And Partial Solution)

I just got my new MBA 13" Mid 2013 last week (updated to Mavericks), and have been having issues with the wifi for a couple days now. Specifically, when I wake my MBA in the morning, it will have disconnected from my home wifi and will not reconnect again. It can see the wifi (and it did ask the WPA2 password after I deleted the network in preferences), but it will not connect due to a "Connection timeout".
I didn't have these issues with my old MBP 13' Early 2011 (also running Mavericks). Also, this only started after I had fully set up my MBA and replaced my MBP, that is, connected it to the external display, hard drive, etc.
Now, it turns out what I have to do is disconnect my external hard drive and reconnect to the network. What kind of architecture makes something like this even possible? And it's not just me, https://discussions.apple.com/message/23423481#23423481 had the same problem: needing to remove a USB device in order to be able to reconnect to his wifi.
This reminds me that with my old MBP, I had an issue where copying large data volumes to external drives via USB would render the wifi connection unusable. So apparently there is something about Macbook architecture that links USB and wifi.
But why does this only occur after a full night of the MBA sleeping? I guess it would have to drop the wifi for energy saving, which it doesn't do right away whenever it goes to sleep?
In any way, this is extremely frustrating. What is the deal with USB and wifi in Macbooks? I really hope Apple can fix this via a software solution, but to be honest, I don't trust them to anymore. I guess for them this is "working as intended".
Cheers
Nate
PS: Please, do not post any links to "troubleshooting steps I may find helpful". I do not, because they were not.

It turns out the MBA doesn't even have to go to sleep for this to happen.
Today i received a new HDD for my time machine backups, so some data transfer was necessary. I made a 600GB backup from my Mac and an external hdd I use for media files, then i started copying another 500 Gb from one external drive to another (USB to USB).
Now in the middle of this transfer (which is rather slow to begin with at around 46 MB/s) my wifi connection just went out. My iPhone, iPad and Windows PC can still connect to my router, but the Mac tells me to "move closer" to it.
It's interesting that my Mac can no longer see any other wifis besides my own, so I guess it's wifi range is somehow impeded by these USB transfers? How does that even work?
At around 50% the data transfer had come to a complete halt, so I interrupted the process. Two seconds after I had ejected AND unplugged both external drives, the MBA could "see again". All visible wifis were listed again and I could connect without problem.
Is there anyone with a similar experience? Is this a hardware defect or an architectural problem? Why have I had these USB/wifi-issues on two Macbook models spaced lmost three years apart?

MacBook Air 2013: Graphical issues

Hey,
I'm experience a few graphic gliches on my MacBook Air 2013. There two types of graphical issues:
1. Horizontal stripes for a few seconds

Mid 2013 Macbook Air serious wifi issues

Okay, so I am basically turning to these forums because I am out of options at this point and am seriously considering selling my Macbook Air. I have a mid-2013 Mabook Air. My Macbook has been an incredibly dependable and efficient laptop until around late August time of 2014. I started having minor wifi connectivity issues (before Yosemite was even out). The problems started with random wifi dropouts, I would get an "icmp timeout" error. I tried dozens upon dozens of fixes for it, from resetting preferences and configurations in the Mac terminal before bootup, deleting the keychain, preferences, I even bought a new freaking wireless router and modem for over $300 bucks. My problems only got WORSE.
My problems still persisted. I moved on to the Yosemite install. Now this past month or two, my Macbook in terms of wifi has become utterly useless. The other night I tried playing my Macbook and it would just constantly disconnect from the wifi. Today I thought I would try reinstalling the operating system and wiping the hard drive. I am in a brand new installation of Yosemite. Now I can't connect to my router at all, I just get a "connection timeout" error" when trying to connect.
Let me say I am an IT professional now and I have tried EVERYTHING in my knowledge of computers to fix the connection problems on this ridiculous laptop. I scoured these forums for hours, tried tons of solutions and suggestions on the web. Below is a complete list:
1) changed system settings and files, basically all the stupid things, the keychain, I've changed settings in terminal, I've reset the cache, I even reinstalled Yosemite entirely while wiping the hard drive, I thought a fresh OSX install would fix any potential system file errors or corrupted areas, guess I was wrong
2) The macbook is not near any other wireless devices and is only 15 feet away from the router
3) I've tried multiple wifi channels and spectrums on my router and even bought a new router and modem with updated firmware which did not fix the problem
4) Tried turning bluetooth off, didn't do crap
5) Nothing else on my network has problems on wifi, and I can turn everything else off and this Macbook will still NOT connect to the wifi
<Edited by Host>

I have seen lots of issues on Yosemite with Wifi (and have been having issues myself), but yours seem different. It is a pretty new computer, have you tried taking it in under Applecare (if you live somewhere this is convenient)? Maybe you just got a defective wifi card. I won't defend Apple over this wifi mess, because it really is terrible, but your issue seems not the same as the ones I've read about while researching how to fix mine (unsucessfully....).

Macbook Air 2013 able to run Logic, iMovie and Final cut?

Hey, I am planning on buying a Macbook Air 13" 2013-version.
I want to use it to record music with logic pro, edit my own youtube-videos with iMovie and maybe a little with Final Cut.
Do you think thats possible?

I'm sorry my thread title is so bad. What I meant is "iMovie and Final Cut Pro quit unexpectedly when importing 720p MP4 files"
Cheers

Cannot get connected on MacBook Air to wifi that previously worked; iPad and iPhone OK

MacBook Air cannot connect to wifi that previously worked; can connect iPad and iPhone. All software current

If this is a new MBA, and the router is filtering hardware ethernet addresses for security, you will have to add the new address to the router. You can get your wireless hardware address from the Terminal:
ifconfig en1 | grep ether
In System Preferences > Network, check the advanced panel for your Wi-Fi, and verify that you have checked Remember networks this computer has joined. If you network SSID name is not in the Preferred Networks list, add [ + ] it, and drag it into preferred order.
Verify your password used is the same as on the two IOS devices.

Macbook Air 2013

I just got myself a new Macbook Air 2013 and while I realized I couldn't expect the smoothest experience, I never expected this much hassle with it. So many differnet issues. No need to have a sad face about it, though - let's get together and figure out how to make this work! At least we only have one graphics chip to worry about this time around
This is going to be a pretty long post but I figured it's good to have it all in one place. Please correct me if you think this is the wrong way to post these things.
Installing and booting
Booting from a normal 2013.6 USB key works fine, but I couldn't seem to get either GRUB or Syslinux working.
I was able to boot by first installing Arch Linux following the Macbook guide at the wiki (having a separate FAT32 /boot partition). Skip the bootloader installation.
Installing rEFInd from OS X (important!) and installing the EFI stub loader made me able to boot fine.
Separate thread.
Stability problems
This is the big worry for me. Every now and then my system hangs for a brief moment and everything involving net or disk access just hangs there for a while and then it seems to work.
So far it only seems to happen when I run something disk- or CPU-intensive. Also had an occassion when I couldn't start X and just got this repeating all over my screen:
ata1.00: failed command: WRITE FPDMA QUEUED
ata1.00: cmd 61/08:f0:10:8c:c2/00:00:0b:00:00/40 tag 30 ncq 4096 out res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout)
ata1.00: status: { DRDY }
On the next attempt it worked fine.
I did SMART short and long tests on my disk and they returned fine:
smartctl -a
There are some messages in my boot that indicate this could be disk and/or ACPI related.
journalctl -b
dmesg
This was on a boot when my NIC was renamed from eth0 to wlp3s0 as noted under Wifi - this should hopefully not be a big deal to fix. Will update when I look more into it.
uname -a:
Linux temperance 3.9.7-1-ARCH #1 SMP PREEMPT Thu Jun 20 22:45:32 CEST 2013 x86_64 GNU/Linux
WiFi
WiFi does not work out of the box. Installing wireless-bcm43142-dkms from AUR made me able to connect to my network. I haven't been able to get it stable yet -interface name changes randomly between wlp3s0 and eth0 between reboots and I get disconnected from my network every 30 minutes or so. Disconnects seem to correlate somewhat with the freezes mentioned above.
Separate thread.
Touchpad
Have only been able to get it to work like a one-button mouse using evdev for now. Looks like an upstream bug.
Separate thread
Audio
In order to get audio, I need to put the following in /etc/asound.conf:
defaults.pcm.card 1
defaults.pcm.device 0
defaults.ctl.card 1
I'm no ALSA pro, but I can only seem to get output from the headphone jack so far - no speakers yet.

While I'm using Ubuntu and not Arch, I wanted to chip in with my experiences.
First, I am happy to tell you that I've found a fix for the ata errors/freezes (which for me were so bad I could hardly install) -- at least I think it's the same or related. I got udevd spitting errors about blkid timing out, and it couldn't find the disks. I found this in a Ubuntu forum -- sadly, I can't find the url now. Anyway, Pass
libata.force=1:noncq
to the linux kernel parameters (in Ubuntu you can add this to /etc/default/grub). This disables NCQ, which according to that post wasn't needed.
YMMV and I am not certain that it doesn't have bad side effects, but for me it made the laptop usable.
Other findings:
My Fn key, and thus delete, page up/down, media keys etc didn't work. That's because the keyboard has a new device id which isn't in usbhid. I added entries like the existing apple keyboards with the new device id (05ac:0291) and after recompiling, it works. I'm pretty sure this is fixable by passing the correct "quirks" flags to the usbhid module, e.g. "quirks=0x05ac:0x0291:0x00001248", but I'm not sure which flags should be set (I have an ISO keyboard layout which is yet another flag).
My sound card doesn't work. Or; i hear no sound at least ;-). After checking in alsamixer, it had two cards, one HDMI with S/PDIF only and one with analog in/out and digital in. I tried passing "index=1" to snd_hda_intel, which makes alsamixer pick up the right card by default. I'm not sure if the problem is that pulseaudio still has the wrong card, or something else.
My wifi works after installing bcmwl from Saucy (i.e. the upcoming Ubuntu 13.10 release), which was a relief because I feared this not being supported.
Sometimes after resuming from suspend, the screen is totally dark -- barely discernible in bright daylight. First I figured this was an issue with lightum (a daemon which monitors the lighting and adjusts keyboard and screen brightness), but after checking /sys/devices/pci0000\:00/0000\:00\:02.0/backlight/acpi_video0/brightness it turns out that when this happens, only the brightness levels 13, 14, and 15 (which is the brightest) have any brighness at all. 12 and under means no backlight. The only "fix" I've found so far is rebooting, which sucks. I hope this will get fixed (I will report a bug on Launchpad next time it happens).
Somewhere I picked up that passing
i915.i915_enable_rc6=1
to the linux parameters enables some great power saving features in the GPU. From modinfo:
i915_enable_rc6:Enable power-saving render C-state 6. Different stages can be selected via bitmask values (0 = disable; 1 = enable rc6; 2 = enable deep rc6; 4 = enable deepest rc6). For example, 3 would enable rc6 and deep rc6, and 7 would enable everything. default: -1 (use per-chip default) (int)
Oh, and if anybody knows how I get my GNU/Linux partition to show up in the Mac boot screen I would be grateful! Right now I have refit installed, which works but I would rather just use the built-in boot manager, which works on the predecessor (MBA 3,2).

IPhone 4s keeps connecting and disconnecting from my new Macbook Air 2013

Ok I've been having this problem, I recently got an 11 inch Macbook Air 2013 and after I try connecting my iPhone 4s it keeps connecting and disconnecting every 1-2 seconds. I already check the community, I know this subject has been asked many times. Nothing worked out though. My cable cord must be fine because it works perfectly on my PC. I updated the OS and iOS to their latest firmware and still nothing. Whenever I try opening iTunes I get this message saying " iTunes could not connect to this iPhone. This device is no longer connected. " Please if anyone fixed this issue I would appreciate some help. Thanks in advance.

I just solved it, I hope this helps everyone who is experiencing the same problem. Apparently the iPhone seems to charge normally and connect to iTunes if the iPhone battery is over 60%-70%. This must be a power issue the MBA has.

[SOLVED] No Audio on Macbook air 2013

Hey all,
Currently I have no sound (either through speakers or headphone jack) on my macbook air 2013.
Card: HDA intel audio controller
Chip: Cirrus logic CS4208
when I boot up alsamixer, it says everything is unmuted and everything is at 100% volume, everything looks like its working fine but still no sound.
Things that I have already done but no effect:
blacklisted snd_intel8x0m (as per ALSA page)
added options snd-hda-intel model=intel-mac-auto to both my sound.conf and modprobe.conf files.
I am running the most up to date version of everything, including kernel version 3.12.8 which is supposed to have out of the box support for the card.
Let me know if you need any other information!
Thanks!

I pretty sure its not that. I use ratpoison as a WM (I like a minimal arrangement for my laptop) which doesn't use pulseaudio. Even when I had Gnome with pulseaudio. I still had the same issue.
So I ran speaker-test -c 2 on my computer and this is the output:

I have also checked amixer and none of the channels are set to 'off

How can I control my my mac mini with my macbook air (no wifi)?

How can I control my my mac mini with my macbook air (no wifi)? Also...what is the best method (less lag) for screen sharing?
I own a mac mini Quad Server 2.0 i7 and I use it for audio production. It's great but I need to travel with it. I was hoping some form of screen sharing could be useful using the macbook air to control the mac mini. Therefore, I'd be using the stronger processor of the mac mini but would still be using the keyboard and trackpad from the air.
My two problems:
1. I can't depend on wifi to make this happen. Wifi is not always available when travleing. What would be the best way to configure a LAN connection?
2. The less lag the better for screen sharing. Which apps are fastest?
Thanks in advance.

Both of your devices have WiFi built in. Here is Apple Support's solution:

Why can't I update bootcamp software on my Macbook Air 2013?

I'm running windows 8 on my 13" macbook air 2013. Apple sent me a notification of updated bootcamp support software and directions for installation. This web page included a list of the models that are supported by this software and mine is one of them. When I began installing this support software an error message said my computer model isn't supported. I called apple care and they told me it isn't their responsibility to supply windows drivers for people running bootcamp. This sounds fishy and completely wrong. Can someone help, please?

Can you go back and post the web page and actual details (drivers, versions, etc)?
Are you trying to update in Windows and from the Apple Software Update application? manually downloading in Windows? you can use either.
Yes, very fishy. Use to be even worse I think with just how well they are ready to answer and help with Windows on Mac topic.
Use to be the old support pages were to me easy to see and find updates and tech support articles but you can still try there for both your Mac, firmware and model specific, and for Boot Camp.
Also when Mac OS X gets updated, often you download new drivers from within Boot Camp Assistant, too, a 3rd method.
Wasn't clear which method was used.

MacBook Air 2013 Camera Problems

I have a MacBook Air 2013 and recently, after the most current update my built-in camera not only does not work with Skype but does not work with Facetime or Photobooth either.
Under "Camera" in System Report my camera does not show up. I have rebooted, shutdown and cold-booted, pressed Shift + Alt + Ctrl + Command when booting.
I don't want to do a fresh install of my (brand new) computer all over again just yet. What should I do? Is it a software issue?
It's rather frustrating because I can't Skype or even Facetime my family and resorting to an external webcam is a ridiculous notion for a laptop.
Thanks,
scintoon

Hey dominic23,
Thanks - that update solved the issue of me not being able to use the webcam. However, now my mic does not work as well. I have rebooted a few times (shut down, cold boot) as well as holding the Shift + Alt + Command when powering up.
Is there a fix to this? Apple seriously needs to fool-proof these updates. Or, at least never have any of these problems in Mavericks
Thanks for all your help.

ISP,INTERNET,SERVER failed on macbook air 2013 13'

hi,i have problem connecting to wi fi with new macbook air 2013 13' 2 days old,network bars showing that im connected all the time,but i cant surf the web,deley btw having and not having connection is about 20-30minutes sometimes is 10 minutes,i tried to reset router several times and its the same,my internet and cable provider is sending 2.4ghz internet,the model of router is
huawei HG532E and i have cable and internet with two devices, router and cable box they are connected each other its a adsl connection.
macbook air comes with mountaine lion 10.8.4 installed i updated to 10.8.5 but i have same problems with both versions of software.
so i run diagnostics and im almost always have first 3 icons green and always (when there is no connection) i have other 3 icons red and failed
ISP
INTERNET
SERVER
and asistent tells me that i need to check my router and access points,all other devices in my home works normaly with the same router.
i know that new macbook air 2103 comes with new 802.11ac Wi-Fi and as far as i know its a 5ghz i read someone have same problem with the same macbook air but different router,and he is assuming that new wi fi AC is not backward compatibile with the older or regular routers,i dont know if this is true but can someone try to help me to solve this problem,maybe i need to change settings in mac?

in the manual i linked up on resent post you can see how to acces the router.
it says
Step 1
Launch a browser on your computer. Enter http://192.168.1.1 in the address box, and press Enter.
Step 2
On the login page, enter your user name and password.
 By default, both the user name and password are user.
 For security reasons or to make the user name and password easy to remember, you can change them. For details, see section 4.1 "Changing the User Name and Password for the Web-Based Configuration Utility".
Step 3
Click Login.
After verification, the web-based configuration utility is displayed.
The first time you log in to the web-based configuration utility, a configuration wizard is displayed. To skip the wizard and further configure your HG532e, click Here when the following message displays: Click Here to enter the advanced configuration page.
and go to advanced configuration page and se WiFi settings, check transfer mode/protocol 802.11 if it is on b/g b/g/n
you can try to set it to 802.11g only and change channel to 11 or 9
Yes you need to do that on your mac when your connected to the network, then you will get an Advance view option over WiFi.
