Mac Book Air wifi 802.11n

Hello.
I've just bought a 2001 mac book air 13'' i7.
Unfortunately I can't use the Fast Wifi 5ghz 802.11n
I've some problem to log to the 5ghz wifi connection of the Airport Extreme. as soon as I try to connect to the 5ghz wifi the book air gives an error:
Time expired to log on Wifi.
Hoever I can log to the 2.4 ghz wifi of the Airport Extreme... so I can use the itenrnet connection
I'm sure that Airport works fine, I've an iMac and a Book Pro that log wihtout any problem to the 5ghz wifi.
Any help will be great.

Make sure that your router is set to one of the 5 GHZ channels that the MBA supports.
Channels 36 and above are 5 GHz channels.
Supported Channels: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 149, 153, 157, 161, 165

Mac book air md711 internet recovery error 2003f

I Hv accidenty delete the partation of mac hdd Then we are trying to internet recovery my mac book air shows me error 2003f Soo whats i do for recovery

Try OS X Recovery.
Startup your Mac while holding down the Command + R keys.
From there you should be able to acess the built in utilities to repair the startup disk if necessary, or restore OS X.
Read before proceeding > About OS X Recovery
Macs no longer come with restore discs.

I have a mac book air 11". When I boot up connected to the huge Thunderbolt screen it detects the detects the fact and gives me great quality. now I am travelling away from the scree it boots up, nice picture, then switches to rubbish resolution.

I have a Mac Book air 11". Normally at home I connect this to a large Thuderbolt Screen. When booting up it some times gets confused and offers me a low resolution result, but some plugging and unplugging of the screen fixes this. I assume it sometimes "sees" the big screen and sets the resolition accordingly. Sometimes does not. But now... I am away from big screen and cannot get the Macbook air on its one to deliver anything other than really poor resolution. I ahve done displays and chosen all three - but no better. And I have said Choose the Best ONe... again not luck. Any ideas. I read in back posts this was a problem a few years ago.

Welcome to Apple Discussions
I believe you have a failing GPU (aka Video Card). Run AHT and see what it tells you. Do not be afraid to run it up to three times in succession if at first it does not detect an error (sometimes errors that are caused by overheating will not show up until the computer is stressed enough - repeating AHT will do that).
As an aside - the MBA was not designed to take the place of a desktop. If you are powering your MBA by leaving it permanently attached to the thunderbolt port on the monitor you are shortening your battery life.

HT204350 Hey, migration from an old mac late 2008 aluminium to a brand new mac book air. Only the new one has firewire. Transmissiom via wifi estimates ~50h. Is there a faster Way to sync? Tanks in advance

I'll venture that your problem here is that you're using two very different versions of Mac OS X. The USB adapter has been useful to me when making big downloads or while using other networks, but it might not be your case.
Here's what I would advise, though it may be less than stellar: Copy the files you need into folders and move them through a USB flash drive or using that external hard drive of yours. (Could the format be the reason your MBA can't see it?). Some stuff like calendars and contacts can be exported too. At least in Lion, I haven't used Tiger in a while.
Good luck.

I have mac book air os x 10.8.2 i create a photo library on iPhoto and i moved it to my time capsule disk now i try to access library from my wife mac book running on mac os x 10.5.8 i always receive library locked on locked disk

Unless you can set the Time Capsule's drive to have it's ownership ignored
you won't be able to use the library on the same volume as the Time Machine backups.

Slow wifi on mac book air.. is this normal? (airdrop)

when using airdrop to send from mac book air (11 inch mid 2011) to a mac book pro (13 inch mid 2011) the wifi airdrop transfers seem very slow. a 5 gig file took 30 minutes to airdrop. when i was at my brothers house and i sent 11 gigs to his imac (unsure which model maybe 2009 <- before thunderbolt) it took 3 hours.
i thought maybe this was airdrops fault, so i connected this mac book air to my mac mini (mid 2010) using airdrop, it also took 30 minutes for 5 gigs.
so i made a manual WEP adhoc connection on channel 48, it also took 30 minutes for 5 gigs. i then tried copying files from another laptop (a dell)
and the 5 gig file copied at the full 300 mbps (or abouts) maybe 5 minutes to the macmini
whats going on here??? is this normal for the mac book air?? do i have a bum wireless card?? i was going to ask a genius to switch out the wifi card or check the antennas but i thought i would post here to see if anyone else has problems
when copying to the mac book pro or the imac i made sure that both computers were connected at 2.4 to different networks, to make sure that 2.4 was
tied up, figuring the simulataneous airdrop connection would prefer 5 ghz. ive seen it sometimes airdrop on the same machines on the same network and taking longer because it was a 802.11g network.

seems like any of the 2 computers on at 2.4 ghz (even on different networks) slows down airdrop. but havingboth computers wifi cards on but not connected to anybody, speeds up airdrop dramatically.
sending from air to mini (air = 5 ghz wifi) mini (2.4 wifi) airdrop speed 12 gigs in 1 hour
sending from air to mini (air = 5 ghz wifi) mini (not connected) air drop speed 12 gigs less then 30 minutes
sending from air to mini (both at 2.4 ghz) 4 hours
sending from air to imac (both at 2.4 ghz on two different networks ) 4 hours

There is no need to download anything to solve this problem.
You may have installed one or more of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it. It's been reported that some variants of the "VSearch" malware block access to the page. If that happens, start in safe mode by holding down the shift key at the startup chime, then try again.
Back up all data before making any changes.
One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, ask for further instructions.
Make sure you don't repeat the mistake that led you to install the malware. It may have come from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
Malware is also found on websites that traffic in pirated content such as video. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
Still in System Preferences, open the App Store or Software Update pane and check the box marked
Install system data files and security updates (OS X 10.10 or later)
or
Download updates automatically (OS X 10.9 or earlier)
if it's not already checked.

Mac book pro can detect wifi but not DNS server

MMy Mac book pro will detect the wifi at school but it won't detect the DNS server meaning that I cannot access the internet! Help!

If the Mac connects to the Wi-Fi network but webpages do not finish loading while using Safari, it may be a DNS issue, try the following:
System Preferences>Network>Select Wi-fi on the left and click on "Advanced..">select DNS tab>add 8.8.8.8 bellow DNS servers>click on OK then Apply.
If thats not the case, please specify to us why you think the mac does not recognize DNS server.

Getting an error when setting up Apple ID on new Mac book air

I am setting up new Mac book air and getting an error at the sign up with Apple ID. Says couldn't sign in because of a server error. Try signing in again

I got this error when setting up a new iMac. I now beleive the reason was that I had already restored accounts and files from a Time Machine backup, and it then connected me to the Apple ID during the login. It is a flaw in the setup process that it didn't check for that and skip the Apple ID step.

My mac book air suddely disconnects many times the wifi while using wifi

Lots of things can impact wifi connections. If you are at the marginal edge of the wifi range (which depends not only on distance, but what's between you and the transmitter) you may find the connection dropping in and out. Sometimes a minor repositioning of the computer or transmitter can solve the issue.
As well, interference can also create problems. For instance, microwave ovens are really good at disrupting 2.4Ghz signals, and that the frequency used most often in wifi routers--so if someone turns on the microwave and it's between you and the transmission point it won't be surprising if the connection drops. As well, metal blocks the signal fairly effectively, so if (say) ductwork is between the CPU and the wireless router there can be problems.
Finally, I've run into some combos of devices and routers that just don't seem to like each other :-) . That said, I've not hit that problem with either Air I'm running (an 11" and a 13"), though obviously I've not tried to connect them to every type of router out there.
Just this week I was at a hotel and in my room the hotel wifi was "interesting" with every device I tried (iPhone, Android phone, Kindle Fire, iPad and the two Airs) dropping connection regularly from the work desk. Turned out if I moved the devices over to the nightstand on the other end of the room (not the best work environment) all of the problems went away, so it clearly was a signal issue and the exact layout of that room and the hotel's wifi.
If the machine has a problem when positioned close to a variety of routers, then I'd suspect a hardware issue with the wifi card in the Air and get that checked by Apple. Similarly, if your problem is with your home router, I'd check to see if other devices also are getting dropped, since there could be a hardware issue on the router.

I keep getting this error message and cannot back up my Mac Book Air to MacBook Air to Time Machine; "Air.sparsebundle" is already in use" how do I correct this?

Restart the Time Capsule. Launch AirPort Utility and check for a firmware update.

Hello skiier4life,
Thanks for using Apple Support Communities.
