MacBook Air 6,2 does not connect to 5GHz network

Hi,
My problem is about wi-fi connection. When I try to connect to my network (Time Capsule 5 GHz), it doesn't connect. Password is right.
Also I try to connect using terminal, and it show me this output:
Failed to join network SML TC 5 ГГц.
Error: -3905 The operation couldn’t be completed. (com.apple.wifi.apple80211API.error error -3905.)
The Mac connect good to regular wi-fi network. My iPhone connect to 5 GHz TC without any problem.
So, can you help me with this issue.
PS. I can give you any required additional info.

Hello:
I just purchased a new Motorola DROID 2 Global, and am having difficulty connecting it to my home WiFi network. My router is a DLINK 655 router, which I have set to 802.11n only with WPA2 encryption and I do not broadcast the SSID. I have gone through the setup process on the DROID 2 by entering the SSID on the phone providing my password etc. The phone keeps attempting to connect to the WiFi network, but just cannot do so. I have a Lenovo laptop which has no problem connecting to the network at the same time, and I have connect it many times.
If I change the router setting to broadcast the SSID, the phone will connect. But as soon as I hide it again, the connection will drop. The saved network setting on the phone will show "Not in range" even though I am standing right next to the router, and the phone connected to it just a minute ago when the SSID was being broadcast.
Has anyone else experienced this problem? Is there a solution to this problem or is this a known limitation of the phone?
A soft reset may resolve your WiFi connectivity concerns. Please remove the battery from your phone while is ON. Re-insert battery after 10 seconds. Power phone ON and allow it to register applications.

I am trying to set up internet sharing from my macbook air but there does not seem to be an option for this because the air is connected to the internet via wifi connection. Is it possible to still share this?

It depends upon how the other machines are connecting to your MBA:
If the the other machines are also using wi-fi, they can connect directly to the wireless access point (router) without going through your MBA
If the other machines are connecting to the MBA using ethernet you can share your wi-fi connection to them

Trying to set up my brand new MacBook Pro and it does not connect with the wifi network I have selected for this purpose. Nothing wrong with the wifi as both my iPad and iPhone are happily connected. Suggestions for connecting to the wifi network accepted

Setting up my brand new MacBook Pro and it will not connect to the wifi network. Nothing wrong with the network which is happily working for my iPhone and iPad! Suggestions accepted for making this connection.

Fixing this is a two step process:
1) System preferences > WiFi/Airport ...
... check [√] Ask to join new networks
"Known networks will be joined automatically.
If no known networks are available, you will
be asked before joining a new network."
2) Remove unwanted networks from the list of "known" networks under
System preferences > WiFi/Airport > (Advanced) > | Airport/WiFi pane ...
Close the window and save changes. If no joy, do a restart to ensure you are playing under the new rules.

Macbook air says airport isn't connect to a network

Lately it's been frustrating to try to use the internet on my MacBook Air. The first time I start Safari each day, it tells me that I'm not connected to the internet at first, and then after a minutes will start to load the apple page. Using search engines is excruciatingly slow. When I try the diagnostic, it tells me that the airport is on but has no network. However, my husband's iMac works just fine on the network that we have established through the airport extreme.
What would make our home network unrecognizable to my latop? The diagnostic doesn't seem able to "find" our home network either, when I ask to join a new network.

Yes, multiple times. Would it be stupid to think that the Airport card was 'accidently' removed when the iMac was getting repaired?
Anything is possible, the only thing I'm not clear on is you mentioned the "The AirPort light is on yellow and its telling me its turned on but not connected to a network." in your original post. What device (iMac, Airport Extreme, Airport Express, etc.. are your referring to?"

[SOLVED] NetworkManager does not connect to WiFi networks

I'm using `networkmanager` to connect WiFi.
I have selected WiFi Name through `networkmanager`.
Next, enter WiFi Password.
But the problem is, `networkmanager` asks me about password again and again and over again and does not connect to WiFi never !!!!
I'm sure WiFi password that I entered is correct.

I just got the mid 2011 macbook air and it does not have ilife or iPhoto on it...isnt it supposed to come with it? and if it does then how do i get it on the mac without having to pay for it in the app store?

I just got a macbook air and i thought that it was supposed to come with ilife already installed? But there is not ilife apps...how do i get it on the laptop without having to buy them all from the app store if it was supposed to come with it?

From the iPhoto Licence:
3. Transfer.
A. Apple Software obtained from the Mac App Store is not transferable. If you sell your Apple-branded hardware to a third party, you must remove the Apple Software from the Apple-branded hardware before doing so.
B. For any preinstalled Apple Software, you may make a one-time permanent transfer of all of your license rights to the Apple Software (in its original form as provided by Apple) to another party, provided that: the Apple Software is transferred together with your Apple-branded hardware; (ii) the transfer must include all of the Apple Software, including all its component parts, printed materials and this License; (iii) you do not retain any copies of the Apple Software, full or partial, including copies stored on a computer or other storage device; (iv) you have not associated the Apple Software with your Mac App Store account as set forth in Section 2B; and (v) the party receiving the Apple Software reads and agrees to accept the terms and conditions of this License.
If the previous owner accepted the preinstalled software (iPhoto, etc) to the AppleID, it cannot be passed on to a new owner. Even if the previous owed would use her or his Applied to install it for you, you would never be able to reinstall it or to update it.
In that case buy your own copies of the software.

Just bought a Macbook Air. I does not appear to be compatible with my LCD projector. What LCD projectors work best with MacBook Air?

My Cannon LCD LV-7210 projector does not recognize my Macbook Air nor does my Macbook Air recognize it is attached to an LCD projector. Yes, I do have the proper adapter.
What LCD projectors work best with Macbook Air? Does this LCD projector have auto-detect for computer?
Thanks!

I've just purchased a *27in (aluminium case) LCD Cinema Display* and am using it with my MacBook Pro, linked by the supplied three-jack cable (Mini DVI display jack).
The 27" display uses Mini DisplayPort, not Mini DVI.
But I also have *a white-cased MacBook (purchased in 2008) which has an older type of display socket*, certainly not compatible with the Mini DVI type.
The early Mac Book uses Mini DVI.
1. Is there a cable or adaptor available to link my older MacBook to the Cinema Display? Nothing in the online store looks 'right'
No. Mini DVI is single-link, and does not support the resolution needed for the 27" display.

New MacBook Air 11" 2012 does not recognize 3G dongle

Hello,
Bought the new 11" 2012 MacBook Air last week. Unfortunately I can't use my 3G dongle with it. (it's a T-Mobile branded Huawei E173) The Air just doesnt recognize it. Even not as disc image. When I plug it into my 15" 2009 MacBook Pro it just works fine. Disc image with the pre-installed software pops up and it can be used to access the internet. It works fine on my 2008 Mac Mini as well and tested it on my dad's 2010 iMac as well. It just won't work in my Air. Any idea??
Thethering from my iPhone is not an option because T-mobile has blocked that. Mifi is too big for my pocket and I don't want to think about charging it all the time. So a dongle is the way to go for me.
Thanks in advance.

Ok, I solved my problem. It cost me some money but I can use a dongle in my Air now...
After reading on another forum how someone else solved this I went the following road: I walked into a Vodafone store and bought the dongle they offer with their dataplan. It's a Vodafone k3770 which is actually a Huawei as well. It has no simlock so it works with my T-Mobile sim. It got recognized immediately by the Air as a drive station and offered the Vodafone software (which cannot be installed on OS X 10.8) But the stick is being recognized as a modem in the network settings of OS X itself. The only thing I did is enter the phone number of T-Mobile *99# and I could connect! If you tick a box there to have to modem status displayed in the menu bar you can just connect by clicking the icon in the OS X menu bar. Awesome! Much better than the crappy software that comes with these dongles.
I made a deal with the Vodafone salesman: if it doesn't work, money back. But it works. But note: in different countries it may be simlocked. I live in The Netherlands and over here it's not locked. It cost me € 60,- but it's worth it because I can't work otherwise....

Macbook Air (11 inch) does NOT go in hibernation mode when battery runs out

Hi,
I have a problem with my new Macbook Air. When the battery runs out to 0% it does NOT go into hibernation mode, it just turns itself off and all my data is lost. It never happened to my old 2008 Macbook Air!
I have all updates, the 1.4Ghz Macbook with 4GB RAM upgrade in case that matters. Hope anyone can help? Is there perhaps a setting where I can set at which Percentage (%) the Macbook should go into hibernation? Thanks in advance!

Noone knows a solution? I also still have problems with my Macbook not waking up properly (like everyone else). The main problem is, however, that it SHUTS down when the battery is empty and does not hibernate!
And I can't install the MacBook Air Late 2010 Software Update 2.0 - I always get this message: "MacBook Air (Late 2010) Software Update can’t be installed on this disc. This volume does not meet the requirements for this update."
- The update also does not show up in Software Update, I had to download it manually!
And I believe its NOT because I have 10.6.6 because I have talked to others who have the same problem under 10.6.5!

Yosemite does not recognize HP printer after upgrade. I can print from my iPhone, but not my 13" Macbook Air (2013)
Are others having the same problems?

Try this. Worked for me.
- turn off your router
- turn off you Mac's after removing all available printers
- turn off all iDevices
- do a factory reset of your printer remove all cables min. 30 sec.
- turn on your router first
- ran the network set up wizard
- give your printer also a new name like "DeskJet 2015"
Something which you don't have used before.
- turn on your Mac's and add your printer
- turn on your iDevices at least.
Should work after these steps.
It worked for me including all iDevices.
iOS and Yosemite

HT201150 macbook air 11" 2013 does not wake from sleep mode. Any ideas?

Since I have changed my macbook air, I had started to have these issues. This is my third macbook air11" and until this one all was fine.All of a sudden I started to have the sleep/wake problem. Oce the lid is closed, it goes to sleep and does not wake up or the battery needs to be charged pops out and I have to charge for 10 minutes and find out that I already have 80-90% battery power. Also the apps open up, but the windows get lost( mail is open, but no window to read the mails) The genius bar checked the laptop twice and finally changed it , but nothing else changed in my life. All the issues are the same, and even getting worse. Just a minute ago, I even lost the WiFi. "There is no hardware message appeared!! Anyone for any ideas?

You're welcome... here's hoping it's not a hardware issue but this test will elimnate any suspicions.
You could also check the startup disk for errors.
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart

My new MacBook Air shut down +does not detect battery + won't charge

My MacBook Air is only a few months old and at random it shut down and when I restarted it the computer did not recognise a batter. I tried to charge the MacBook but the light on the charger did not turn on at all and the charger was not recognized at all. The MacBook does not detect any wifi's at all aswell

You have to take the computer to the Apple store to have it checked out.
Try resetting SMC before that.

MacBook Air 11 in. does not hold a charge

I have a brand new MacBook Air 11 inch computer that I got in the fall of 2013. It does not hold a charge for very long, probably only 2-3 hours before I have to charge it again. This happens even though I always have my brightness on low. When I shut down my computer at the end of the night and go to use it the next day, the battery will also be drained. I do not know why this happens...

1. did you often drain the battery very low?
2. did you often /always have your macbook on charge,......or did you often / always BOTH have your macbook on charge AND in sleep mode?
1 or 2 are harsh on the battery chemistry and therefore its longevity
all batteries are consumables meant to replaced either in their own "due time" or early due to abuse / misuse.

Macbook Pro 10.6+ will not connect to wifi network

Having a strange issue with one particular Macbook Pro not being able to connect to the internal wifi. There are 5 machines, mix of Windows and OS X, none have this issue. We have a wireless network coming from a SonicWall router with wireless capability. This particular Macbook will not connect to the wifi. Just an "!" symbol around the wifi. It has no issues connecting to any other wifi in the area, even to a second on within the same floor.
What are steps to troubleshoot? I am an advanced Windows user and would check ipconfigs, flushdns, among plethora of other things. I am not so sure about what to do in OS X (10.6 or 10.7, not sure).
Any guidance would be appreciated.

I can assure you it is not the router. I am pretty good with Windows and Networking, particularly these model routers. This is an issue on the laptop. I feel as if it keeps remembering old credentials to this wifi network (when user kept typing the wrong password). Once I changed the WiFi password, it no longer even asks me to update the WiFi password when attempting to connect. I have to manually try to connect to it by inputting SSID and password and still does not accept.

2.4Ghz MacBook Pro 2010 model doesw not connect to n network.

I have three Mac's one iMac, one Mac Mini (2010) and a brand new 13" MacBook Pro. I am using a Buffalo WHR-HP-GN wireless N router. All the computers except the MacBook Pro connect at N speeds, but the MacBook Pro connects at G speeds. All the computers are in the same room so distance is not the problem. I thought interference was the problem, so I turned off WiFi on the other computers and used Ethernet cables. Still the MacBook Pro would not connect at N speeds. I brought it to the Apple store and it connects at N speeds there. Any ideas why it will not connect here at home?

Yes it helps clarify, but no it doesn't answer your particular problem. The Wireless Network Access: Allow All would be the parameter I asked about.
You indicated it was 802.11b (only?) network. If so, it would be a pretty old unit. Linksys Model ?what? Perhaps you should check its firmware and see if there have been updates posted on the Linksys support site.
