my daughters mac air 2013 just does it on her user (standard) account using either safari, chrome, firefox. safari is a little better. try all other comments. i have the latest airport extreme. However, my Admin User, Guest, and another test standard accounts seems to operate properly. all browser settings were the same setup between accounts. all these other accounts are not linked to an Apple ID. tried on and off many times, the same results. Maybe my daughters account somehow got compromised. Her Icloud account is completely full of her pictures. She mostly uses chrome. Is the problem with synchronizing with Icloud that is full?
I have 2013 13" with the i7 processor and 8 GB of ram.
I was having excruciating wifi issues previously which resulted in me turning off bluetooth and using a Ethernet adapter.
I recently switched from my Linksys WRT54GL to the airport express.
I am also running on 10.9.3 with bluetooth on and 3 BT devices connected (keyboard, mouse, and speakers).
Since updating to 10.9.3 and switching the router, all has been working fine.
I wish I could pinpoint what change made the problem disappear but I have no clue.
If there are any system logs or any other reports I can provide to help, let me know and I will.
A possible scenario that might be in play is that apple implemented something in the ethernet (layer 2) packet headers indicating something about the device (the macbook air itself). This in turn would help airports determine in what capcity they can communicate with that device and under what circumstances (power nap?). (perhaps this is already part of the RFCs as it relates to layer 2 network headers?)
If the router isn't capable of this kind of proprietary (actually don't know if it is proprietary or now) header info then I could see the macbook air incorrectly determining when it is ok to turn off the adapter to save power.
Now I kind of think that the OS should instead default back to "normal" failsafe behavior. This assumes this scenario is what's actually happening.
Whatever is happening it seems like the Air is not defaulting to a failsafe sort of behavior.
Someone w/ a new airport and a non-apple router might do a packet capture with wireshark or tcpdump to see if there are any distinct differences in packet headers.
I have been using 10.9.x throughout and I've tried every combination of beta and releases, but the only real solution for me was to swap to a new basestation for my one particular problematic connection at work. The rest of the connections at home and everywhere else (wifi sharing to iphone or ipad) seems to work fine.
I can still try connecting to the problematic station to see if anything has been fixed but sadly none of the proposed solutions have solved this for me. All other devices (iphone, ipad, PCs) have no problems with this base station except my 2013MBA. I dread the day when I find another base station that fails like this one and I have no alternatives.
I must admin first, that I've read this complete articles before asking here:
- 2013 MacBook Air WiFi Problems (high latency, dropped connections) [Updated]
- New Macbook Air - wifi connectivity problems (the 141 pages all of them)
- How-to Fix OS X 10.9 Mavericks – Wi-Fi Issues
- Late 2013 Macbook Pro Retina 13'' Wifi Issues (the 44 pages all of them)
- And some other pages looking for "macbook pro late 2013 network issues"
I have my "old" 2008 Macbook Pro, and I've bought a new one (late 2013 version). I've experienced serious network issues, not only WiFi as everybody is claiming on the Internet, but also ethernet network issues, and I'd like to share here my benchmarcks.
I've tried everything described in those articles and others I found, as to:
- clean PRAM
- reset SMC
- delete System Configuration folder (bluetooth and/or wifi and/or complete folder)
- upgrade to 10.9.3
- change order (to put Wifi first) in network preferences locations
- disable iCloud completely
- disable "Wake for Wi-Fi network access" in Energy Saver
- disable bluetooth
- create a little script to ping every 0.2 the router
- reinstall everything (fresh install 10.9)
All tests were done in a clean environtment (just the current testing device connected to the network), and even reseting router in each test. My network is a 100Mb fiber optic. (I performed other tests in 3 other 100Mb networks and in a 50Mb network, and results are the same). I also did tests with a Windows 7, and Windows 8 laptops and have no problems at all (obviously).
I did all tests with http://testvelocidad.eu, a page when you can check network speed.
TESTS WITH MACBOOK PRO 2008
Ethernet. Speed shown in tests (in Mbps): 74, 79, 71, 82, 74, 81, 89, 70, 25, 76, 81, 83, 77, 79 (average 74.3, top of 89!)
Wifi. Speed shown in tests (in Mbps): 45, 48, 50, 44, 41, 47, 39, 45, 43, 36, 41, 42, 49, 50 (average 44.2, top of 50!)
- This Macbook connects to my WiFi with 802.11n
- Bluetooth does not affect the tests at all
- The graph grows normally and test is running well
TESTS WITH NEW MACBOOK PRO LATE 2013
Ethernet. Speed shown in tests (in Mbps): 43, 45, 42, 40, 40, 30, 35, 44, 37, 35, 39, 48, 37, 36 (average 39.3) << SLOW !! Top 48
Wifi. Speed shown in tests (in Mbps): 24, 23, 18, 21, 24, 25, 22, 23, 20, 24, 19, 23, 21, 20 (average 21.9) << SLOW !! Top 25
- New Macbook connects to my WiFi with 802.11g, impossible to get a "n" connection even touching everything in router. I had an option to just connect to "n" networks, and then WiFi does not even recognize my network.
- I tried with DHCP, and static IP (both in WiFI and ethernet tests)
- I tried changing the MTU manually to 1453 as some forums said (in WiFi test) (https://www.google.es/search?client=safari&rls=en&q=macbook+wifi+issues+change+m tu+manually)
- It's curious when running the test (both in WiFI and ethernet tests), the graph is growing and after 4/5 seconds, it shows flat line for the rest of the 10 seconds test, never grows again (http://cl.ly/image/1w473J0L0J2I)
Ethernet. Speed shown in tests (in Mbps): 41, 45, 40, 39, 47, 46, 46, 43, 42, 41, 46, 47, 49, 47, 42, 44 (average 44) << SLOW AGAIN !! Top 49
Wifi. Speed shown in tests (in Mbps): 3, 5, 4, 3, 2, 4, 5, 4, 4, 3, 3, 2, 3, 3, 3, 3, 4, 3 (average 3.3) << DRAMATICALLY SLOW !! Top 5
- It's curious when running some of the tests, that after 2 seconds, the graph is frozen, does not move at all for 3/4 seconds and then the test finishes suddenly, it seems the network hangouts for a while!
Summarizing questions happening JUST IN NEW MACBOOK PRO:
- Why Bluetooth is affecting drastically the WiFi performance ? (from average to 25 to 5)
- Why even turning off Bluetooth I can't get the same network Wifi speed as old laptop does ? (from average to 44 to 21)
- Why I can't get the same network ethernet speed as old laptop does ? (from average to 74 to 44)
- Why can't Ethernet connection can't get more than 45/50 Mbps in all cases ?
- Why can't I connect to 802.11n networks (more people happening,http://apple.stackexchange.com/questions/131455/why-doesnt-my-macbook-pro-retina -connect-to-802-11n) ?
I know I can change the laptop for other new (store staff told me so, and I have Apple Care too), but I think this will happen again, since it's a hardware/software issue from Apple.
Thank you for any help
I think it would be worthwhile for *everyone* affected by this problem to go and sign up for Apple's beta program. It is free. You may need to use beta software, but it does include a program called "Feedback Assistant."
This is where you can provide feedback that goes to the Mac OS X development team as they are building the next (incremental) update. Reporting your problem through that channel is probably better than only reporting it through here or the Genius Bar.
I have been waiting a week to post this, but since I upgraded to 10.9.3, I and 12 of my co workers, have not had any issues with disconnects.
About 6 Late 2013 MBP Retina and 6 Late 2013 MB Air's Retina
(hope I didn't jinx this!)
I didn't see anything in the release about this issue though..... hmmm?
Hello guys, I bought a new MacBook Air 13" today (late 2013 model) and experienced the same wifi connectivity issues as everyone else on this forum. It was right away considered something related to bluetooth, which I could confirm as disabling any bluetooth devices temporarily increased my wifi speed.
However, turning off bluetooth, turning off bluetooth devices, turning off bluetooth on any other computer in the house and deleting the bluetooth plist files did not help.
But, I came across this one fix hidden under an article at LifeHacker I believe and it suggested changing the network service order under network. The moment I kept Wifi first (initially Bluetooth was), my wifi speeds returned to normal.
Forgive me if this has been posted and hasn't worked for most, but I thought it was worth sharing.
Hope this helped, and if it didn't, forgive me for not reading through the previous 141 pages to check whether this isn't a repeated solution.
Just after about 2 minutes after this "magic fix", the Air started misbehaving again.
However, after a few painstaking hours of downloading the 10.9.3 software update, deleting bluetooth preference plist files and experimenting with turnign bluetooth on and off(I can turn BT on and off now with no problems), the problem seems to have been fixed, FOR THE MOST PART.
I still have those moments where the speed randomly halves, and as an article pointed out, seems to be with how it goes into a low power mode to conserve battery. I have turned off Power Nap and kept "wake for Wifi access" on. Hopefully the combination of these things helps yoo guys out too.
I have a new MacAir. It has these problems too, None of which are experienced with older macbook with Snow Leopard. MacAir crashes with every sleep - must be rebooted. First internet connection after bootup takes 6-7 minutes (using Verison DSL) Then each page rendering takes 1-3 minutes per site request. After about 10 minutes it operates normally. I then quickly turn on VPN to keep the signal. Download speeds are ok. Just no connectivity. Same using Firefox or Safari.
