Why does the Mac Airs keep dropping the network

We are using WEP and or WPA-WPA2 Personal. Once the lid is closed and reopend, system ask for admin user name and password. This happens on just the Macbook Airs. Our WAP's are Cisco. Or when a teacher is working with the unit, the signal will just drop for a few minutes, then come back up. Any one else having this issue and what did you do to resolve thie problem?
Thank.

Might be some of the same issues in this thread assuming your MBA is a 2013 model

  • Why does my Mac Air keeps logging out and restarting

    Can you explain to me why my Mac Air keeps giving me this message? In the middle of a download and I get this when the computer goes into sleep. Once I get this message it will keep trying to log out until finally I log out and then back in again.

    From the menu bar, select
               ▹ System Preferences... ▹ Security & Privacy
    If there's a closed padlock icon in the lower left corner of the preference pane, click it and enter your login password when prompted.
    Click the Advanced button and, in the sheet that opens, uncheck the box marked
              Log out after … minutes of inactivity

  • Why does my iphone 4 keep dropping wifi connection since ios5.0.1update

    Why does my iphone 4 keep dropping wifi connection since ios5.0.1 update, it worked perfectly before, my wifes 3gs connects fine and stays connected while my £400 paperweight losses connection, thinking of going back to nokia! Sort it out apple!

    If the "oh so Great Apple" were to monitor these forums then they might see all the problems
    that the people who have paid good money for their devices are having, i suppose they can do no wrong
    In your eyes, i just thought that if you pay a lot of money for a product that works fine, and you update
    It with a firmware update that they kept going on about how good it was and it can do this and it can
    Do that, then i think they should sort it out. I don't care if i "don't deserve to be an apple owner" or not,
    The fact is i paid my money and it should do what its suppose to do, i moved from Nokia to Apple because
    The N97 was crap and i put up with it for too long, and they didn't do anything to fix the bugs they just stopped
    Selling it and basically said tough s**t, so now this is happened i hoped Apple whould be better but they seem
    To be just like the rest.

  • Why does my mac air always restart when I open it in our university?

    Why does my mac air always restart when I open it in our university?
    This has been always bothering me for some time already. Whenever I open my macbook air in our university it always warns me to restart my device. When I do the same thing happens over and over again until it reached 27 reports.

    I'd make a sound too if i was put into a bag haha.
    Only thing i could think of it it has a mind of its own or your putting your computer to sleep. Try shutting down your mac before placing in your bag and see if that changes things.

  • Why does my apple tv keep dropping out of home sharing.

    why does my apple tv keep dropping out of home sharing.

    I use homeplug powerline adapters to create my home Lan. I've never had any problem with my ATV 2.
    This isn't ideal either, I would rather have shielded CAT7 cables reach all the way to my modem.
    Either way, wired solutions are more reliable and have a higher potential speed as wireless uses pulsed electromagnetic radiation as a means for transportation in stead of copper or fiber optic cables
    The World Health Organization's IARC has recently classified radio frequency electromagnetic fields as possibly level 2 carcinogenic to humans, concluding:
    "the evidence, while still accumulating, is strong enough to support a conclusion and the 2B classification. The conclusion means that there could be some risk, and therefore we need to keep a close watch for a link between cell phones and cancer risk."

  • Why does my ipad 2 keep dropping the connection to my BT Home Hub, whilst streaming video, since upgrading to IOS 6?

    Ever since i have upgraded to IOS6 My connection to my BT Hub 3 wifi router keeps dropping out whenever i am streaming video. I have an Apple TV connected as well which is fine as are other devices, its just the Ipad since the move to IOS6. It is really frustrating and i had hoped the 6.01 release would have resolved it, but it didnt. I have seen other similar comments, i just want to know if this is a common known fault which Apple are going to fix.
    The strength of Apple has always been 'it just works' , i can't help but feel that there are cracks appearing in this.
    David

    Some things to try first:
    1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    4. Go into your router security settings and change from WEP to WPA with AES.
    5.  Renew IP Address: (especially if you are droping internet connection)
        •    Launch Settings app
        •    Tap on Wi-Fi
        •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
        •    In the window that opens, tap on the Renew Lease button

  • Why does my Mac air make a lot of noise with the fan inside?

    I bought Mac air one year ago. at the beginning, I satisfied with the product. However, 8 months later, the laptop made a lot of noise from the fan inside. When I I run about 4 or 5 solfwares, it starts warmer and make noise. I feel so unhappy with this. How can I fix it. I bought AppleCare programme for 3 years as well
    Thanks

    The mid 2011 MacBook Air fans are pretty quiet but not silent and since they are the only mechanical decice you'll hear - there's no hard drive or DVD drive to make noise - it is possible that what you hear is normal. On the other hand, fans can go bad - bearings fail and dust an make the blades become unbalanced. None of us can help - you'll need to take the computer to a repair center or Apple Store and let an Apple repair person determine if the fans need replacing or not. If so, your warranty will cover the cost.
