Macbook Air wifi issue

I have a problem with my macbook air. I can find easily my home network, and it usually works ok at the begining, but after some time, 5-10 minutes, it started to works very slow, or just stop responding at all. Than I cant open any page, cant download mail, or anything. Sometime if I move my macbook air to another location it starts to work again for some time, but sometimes that doesn't help either. Sometime it helps to turn wifi off, than on again, but that also works for some time, and than again it blocks. I had mac os x lion, and now I have mountain lion, and same problem occurs. I even reinstall mountain lion, because I thought maybe it's the software issue, but it happening again. Today I changed my router, because before I had one with only B\G, and now I took one with N standard, because I thought this happening because of old router, but it happened today again.
Could this be a hardware issue? Should I bring it to apple store, and what can I expect? Would they give me another one if this is hardware issue, or I would get refurbished one, or they will try to repair this one? I don't know what to do.

With the help of Apple Support this problem seems to be cured.
Here is a summary of the steps that they took me through:-
In Settings>Network>
Click on Gear Wheel beside +- at bottom of list of network services, select "Set Service Order" and check that WiFi is at the top of the list.
Click on Advanced and select DNS tab. Click on + at bottom of DNS Servers List and enter 8.8.8.8
In WiFi tab check that your preferred network is at the top of the list.
Apply any changes that have been made and switch off.
Reset SMC and NVRAM/PRAM
Check that there are no channel conflicts with other wifi networks.

MacBook Air WiFi issues

Ok, I recently got a MacBook Air 2013 that it currently OS X version 10.8.3 and it's great except for its absolutely attrocious WiFi problems. For example, after awakening from sleep, the MacBook almost always requires my password for my network even though I have the "remember this network" box checked. More than often, when I enter the password for my network, it will keep saying invalid password, even though I know the password is correct. The only way for me to fix this is to shut down the MBA and reboot it. Simply restarting doesn't fix this password issue.
Sometimes when my WiFi is working, the pages on all my browsers won't even load and the "webpage not found" oage shows up. And so I turn WiFi off then on and the problems I stated above reoccur. Is this an OS X problem or the MBA itself? This is absolutely ridiculous and any suggestions would be greatly appreciated. Thanks.

J_BB,
Check which model wireless router you're using (Netgear, Linksys, Motorola). The device type (WRT-54, etc) will be on the side or back.
Google your device model & type to determine its LAN gateway IP; most use 192.168.0.1 or 192.168.1.1
Enter this address in your browser's URL window to access your device's main settings page. If prompted for a username and password, you can find the defaults by googling. You should personalize these after you are done making changes for security purposes.
The default username and password should be on the same page you searched that brought up your model & type. If not, there are pages devoted to collating such information (google is your friend).
For most devices, your SSID (Service Set ID), or the wireless network name which is broadcast, will be the name of the router. Check out these links for a commonly used device (Linksys WRT-54G) - you can click through items as though you are making actual changes:

The option to change channels is under the 'Wireless' heading
Save settings when you're finished.
Good Luck!

Mid-2012 MacBook Air WiFi Reconnect-Partial Solution

The MacBook Air seems to have some significant WiFi issues for a lot of users. My issue is as follows: the MacBook will connect to any compatible WiFi hot-spot with no problems, and it will maintain the connection almost always. The problems come when I try to reconnect to the internet over the same WiFi hot-spot after waking up the MacBook. Even more frustratingly, the problem is not consistent. Sometimes it works, and sometimes it doesn't. After some investigation, I have come to the conclusion that reconnection problems happen when:
You wake the computer up from computer sleep (not display sleep or Power Nap)
You are using a specific cable modem (the one I tested on was a Motorola SURFboard SBG6580 DOCSIS 3.0)
You have not restarted your cable modem while your MacBook was asleep
The MacBook Air will connect to the WiFi network (i.e., it can access other devices in the wireless LAN) when woken from computer sleep; it just will not connect to the internet
The only way to get the connection back is to restart the cable modem. Restarting the MacBook, restarting your WiFi base station (in my case a brand new AirPort Time Capsule tower), having the MacBook forget the WiFi network and then reconnect--all do not work. But if I just restart the cable modem, the MacBook connects with no problems. This is a problem specific to the MacBook Air because none of my other devices ever have a problem connecting to the network after waking up from sleep (including a Lenovo ThinkPad E530c). As has been proposed in some of the many discussions about MacBook Air WiFi issues, I think it has to do with the bleeding-edge power saving modes that the MacBook Air enters in to when it goes to sleep. Apparently, the computer sleep mode will cause it to not be able to reconnect to the internet, so it seems to be some sort of incompatibility or bug between the MacBook Air and the cable modem--in my case, the Motorola SURFboard.
So that's the problem, but I do have a partial solution while the engineers figure out a fix. Set the System Prefs > Energy Saver setting on the MacBook to never go into computer sleep (I set it only for Power Adapter, not Battery). In my case, this is a workable solution because I have my MacBook Air plugged in at home almost all the time. I have lived with these settings for a couple of days now and whenever I wake up my computer, it still has the internet connection and works as expected. And if for some reason I don't plug it in and it goes into computer sleep, I don't waste time troubleshooting. I just restart the cable modem and after a minute or so, the internet connection is re-established. I'd be curious to know how many cable modems this happens with, and if anyone has a fix having to do with cable modem settings (the Motorola SURFboard, to my knowledge, doesn't have a web app interface to tweak settings, perhaps because my cable company doesn't want me tweaking things, but I frankly have not spent any time researching that end of things).
Hopefully this will help some MacBook Air owners (is this an issue with MacBook Pros?) that have this problem.
Good luck!

Have the same problem. Was OK for nearly two years then started two days ago.

MacBook Air wifi internet shared network not working on tethered android phone GT B5122

MacBook Air wifi internet shared network not working on tethered android phone GT B5122
I have created a password protected wifi internet network on my Macbook air. I tethered by Andriod phone onto this network, but the internet connection works intermittently on the phone, and when it stops working the network continues to show as connected to the shared network mostly(other times it keeps renewing the wifi IP address on the Andriod phone).
Also the network the MBA is connected to, is a hardwired one using a SSH login account in a student accomadations.
I am not sure, but all the restarting and refreshing of system, phone and wifi sharing and re-enabling wifi is not reparing the internet connecting on the wifi network for the phone
Really puzzled, if this is one of the Apple, Andriod compatability issues.
Cheers,
Vivek

Hi.
I'm having trouble with the wireless connection on my new home hub 3. Most devices will connect easily, but there are three devices that have trouble connecting. These are an Android Phone (Samsung Galaxy Mini), an android tablet (Sony Tablet S) and an iPod. All of these devices work perfectly on other network connections, and other devices in the house are quite happy connecting to the network.
The Androids can see the network, and will try to connect to it, but when they do they just go through a loop of "connecting">>"acquiring IP address">>"disconnected". I have tried resetting the Home Hub with a pin, and that lets the devices connect for about 24 hours, but after that time they stop connecting again.
I'm really not sure what to do to fix the problem, so I will very much appreciate some help.
Many Thanks.
My lads SGMini connects perfectly to our hub3
Have you installed the BTFon app to these devices?
If so, you could delete it and then see what hapens.....

Is the New MacBook Air Wifi N Dual-Band or Single-Band?

Is the New MacBook Air Wifi N Dual-Band or Single-Band? I cannot find any official information regarding this.
I have a Dual-Band router up to 450+450 and I'd like to know if the Mac would make the most of what I have.
Another related question would be… if the MacBook's Wifi could take up to 450mbs or would it only reach up to 300mbs?
Thank you!

Thank you Captfred for the quick clarification. A related question (and this might be obvious, I'm not sure) would be if the MBA uses single or dual antenna? I am not sure if N technologies always use dual antenna by default? The reason why I'd like to understand this is because I do watch quite a bit of streaming video. I supposed streaming through a single antenna could clog the connection quite a bit if at the same time I'm browsing other websites or download something else at the same time? While having two antennas would ease the communication by sending a request through one antenna and receiving the response through the other?
Best,
M

MacBook Air WiFi Connectivity Issue

I bought a MacBook Air 13" yesterday and I've noticed that my WiFi keeps dropping out. The WiFi icon in the menubar says it's connected and network in sys prefs says so too. But no pages will load and I can't ping anything. I have to turn WiFi off and back on for it to work. I've noticed it also does this with my iMac (mid 2011). On my old 2011 MacBook Pro 13" I never had this issue.
Does anyone have any solutions or should I just take it to Apple?

Not an issue with my router. Works fine on all my other devices, and I had the same issue earlier today at a different location using a different network.

Iphone 5c and Macbook Air wifi problems

Just bought an iphone 5c and got the new macbook air in September. Everything has been great with my macbook air until I got my iphone 5c. The problem comes when I have both the phone and laptop together, connected to my home wifi. Only one will connect at a time, on my iphone it wont even recognise my home wifi but as soon as I disconnect my laptop the wifi becomes visable. I know its not a router issue, Ive turned it on and off and it only works for about 5 minutes. Can anyone tell me what the think is going on or how to fix it? Thanks, Eva

What exactly have you tried? Did you try different security settings? Which ones did you try? Were there any more successful than another? Which one was it on when it worked for a few seconds? Is the router running the latest firmware?

Macbook air wifi connection problem?

Hello Apple Communities
So i recently pre-ordered a custom built 13inch macbook air, and i am just wondering
if theres still any issues with the wifi connection. I living in Australia by the way.
Thanks!

I don't know that 802.11 ac is the clear answer - but - if you have broadband access that is likely to support ac (not all is/can) in my opinion it would be wise to look to the future and buy an ac supporting router. Certainly those with older routers have more problems, and updating firmware (when possible) seem to cure some.
Some claim dissabling Bluetooth was their unhappy solution.
Certainly part of the "fix" for some appears to be to use 5Ghz and g/n settings as opposed to 2Ghz and a/b.
For others new hardware (returning/exchanging the device) was a solution.
There are moderators (who will quickly correct - or remove) this reply if I've made any false or misleading statements.

Mid 2013 Haswell Macbook Air Wifi problem: software or hardware?

I have the 11" Macbook Air (mid-June 2013, Haswell) and it has problems connecting to wifi. It reluctantly connects after searching for the network for a few minutes, but then it stays connected.
My question is: can anyone tell me if this is a hardware issue (in which case return/repair is necessary) or a software issue? If it can be fixed by an update, I don't mind waiting, but I don't want to waste my time if the machine is physically defective.

There is an update available now.

2013 Macbook Air Sound Issues

Alright so I've had my 2013, 13" i7 8GB/512GB Macbook Air for around 2 months. A while back I began encountering issues where the system's sound would just stop working. This issue applies to outputting through headphones and the built in speaker. I pinpointed the problem to occuring only when I closed the laptop while a program was outputting audio through headphones. Examples of programs this has happened with include Spotify, iTunes, and anything that uses audion in Safari (including Netflix and Youtube). After ths occurs, the only way I have found to fix the problem is a complete restart. I am interested to find other people who have, or who have fixed this problem.
On an unrelated note, I have also found a bug where sometimes when I accidently press the power button once and put it to sleep, the computer will sleep but the backlight on the keyboard will stay on. When I press the spacebar to turn it back on, the backlight on the screen will turn on, but the screen will remain black and unchanging. Again, the only thing that will fix this is a forced restart.
Any help that anyone can provide would be greatly appreciated.

Do not sleep your Air (close the monitor with headphones attached) with headphones attached, this is known to affect some Air under Mavericks.
* this occurrence is being looked into.
Much testing on my own and others as well show that in some instances this occurs in Mavericks.
If you choose you may contact Apple for an appt and diagnostics.
However as said, refrain from having phones attached when you close the monitor to prevent this until it is resolved
Also if you have the APP "BOOM" installed, uninstall it, this can cause same as Ive confirmed.

Upgrading the OS should have no effect on your keyboard.

Macbook Pro Wifi Issue

I incorrectly posted this in the wrong thread this morning.
I'm hopeful you might be able to help me diagnose a problem I'm having. I'll provide as much detail as possible.
I have a first generation MacBook Pro. As of this morning I was running 10.5.6 and up until this week was using a linksys router and a comcast cable modem.
I used to have a great wifi signal throughout the house (always full strength), and around 12-18 months ago noticed the signal would weaken. The best I would get would be minus the top bar on the signal, and usually only if I was directly above or next to the room with the router. There were no new phones or devices added that might adjust the signal. On the other side of the house, I would have no signal at all.
My wife has a nine year old ibook and has no issues connecting through wifi.
When I bring my laptop to her parents' house or to the Apple store, where they use Belkin on N or Airport Extreme, I get a full signal.
I've recently suffered a hard drive failure and had a replacement drive installed. The problem persists despite the software update.
Not knowing if it was a router issue or an airport card issue or a combination thereof, I went to the Genius Bar. The genius recommended I upgrade my router to Airport Extreme, and if that doesn't work to return it and he'd focus on the airport card or antenna. I could get the flat rate repair (no AppleCare at this point) for $320+ to repair the problem if Extreme didn't work.
I installed the Airport Extreme router and got a full signal in the basement, far side of the house, upstairs - everywhere. Until around 10pm. The signal died from the basement. If I walked into the room with the Airport Extreme router, I'd get a full signal. If I left the room, I'd get a partial signal. If I walked any distance (10-12 feet), the signal would die. I restarted both the modem and router with no change. I reinstalled the linksys router and got a depreciated connection. I restarted the Airport Extreme again and got a full signal throughout the night, morning, through restarts, and when I returned home from work.
Last evening after using youtube extensively it died again. Linksys would barely work if I switched back, and no matter how many times I restarted I couldn't get the signal to last outside of the area of the router. I left it in the basement overnight shut down, restarted this morning, and had a full signal.
I'm looking for any potential guesses as to what may be causing the problem. I don't want to replace the card if it's the antenna or sink too much cash into a machine if it's a heat related issue linked to Generation 1 syndrome.
During all of this the ten year old ibook works fine. I know a lot of macbook pros have issues with their wireless and don't want to sink in the cash if it's more complex than that. Any advice is much appreciated!

Hi nashie1002,
If you are having issues connecting to your WPA2 WiFi network after a recent update, you may find the troubleshooting steps and settings in the following articles helpful:

It may also be worth doing a search for the specific model number of your router to see if anyone has noted any issues with Mavericks.

Lion Macbook Air installation Issues - Won't Install

I sucessfully installed Lion on my iMac, then I downloaded it with my same user id from my macbook air (1.4ghz). I proceed with the installation, it claims to finish and then reboots. The Lion App store icon then sits on my dock and the computer is still running Snow Leopard at least it seems to be. However, when I go to about this mac it says 10.7.
This is a mistake since the machine is still physically running snow leopard, there is no mission control, no air drop, etc, AND the lion icon is still in my dock waiting to install!
I have repeated this process countless times and keep getting the same results.
Please help!

did you mean to say 'this problem has been SOLVED' ?
i'm having the same issue.... and always presumed the downloaded lion install was fine since it does image checking, etc.
either way.... i'll be giving it another download and try again

Macbook air wifi keeps dropping after sleep

This is driving me crazy. I have tried so many fixes but nothing has worked. Every time I hibernate / sleep my 2012 macbook air, the wifi drops and takes at least 20 minutes to come back on when I open the laptop again.
I can reboot, turn the wifi off and on, change preferences...everything. Nothing works. From reading around I am assuming this is a Maverick problem since lots of people seem to be complaining about the same thing, but has anyone found something to remedy it?
Thanks x

Test after taking each of the following steps that you haven't already tried. Back up all data before making any changes.
1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved. Make sure the box marked
Remember networks this computer has joined
is checked.
2. Follow the instructions in this support article under the heading
Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
3. Reset the PRAM.
4. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
5. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
6. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
7. Repair permissions on the startup volume.
8. Turn off Bluetooth and test.
9. Reset the System Management Controller.
10. This step shouldn't be necessary, but has been advised by Apple Support in some cases, apparently as a workaround for a bug. Open the Energy Saver pane in System Preferences. If applicable, click the padlock icon in the lower left corner to unlock the settings. Enter your administrator login password when prompted.
Select the Power Adapter tab and uncheck the boxes marked
Wake for Wi-Fi network access
and
Enable Power Nap...
if present. Then, if the computer is a MacBook, select the Battery tab and uncheck
Enable Power Nap...
11. Reinstall OS X.
