Hey Babakgh,
I understand that you've experienced recent issues with your Wi-Fi network where you can only connect to it if you're close to the router. I would start off troubleshooting your Wi-Fi network by following the steps in here:

About AirPlay and Airplay Mirroring
AirPlay Mirroring requires a second-generation Apple TV or later, and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer). For non-qualifying Macs you can try using Air Parrot.

Thanks to the $15 Beamer, AirPlay streaming is still possible on Macs that do not support Airplay and mirroring.
Other solutions are the Air Parrot, StreamToMe, and AirServer. -

I am unable to attach/send a 2486KB file when using Firefox browser. I am able to attach and send via Internet Explorer though. Up until a few days ago, this was never a problem. I've sent the file before. What could be the problem? I am very frustrated.
I do have anti-virus software that scans the files. It sounds like you are accurate. But nothing is new...I have sent the same file numerous times in the past with no problems, but all of sudden, I can't send the file. What can I do to fix this problem?

May macbook air can not turnoff! what is the problem?
my macbook air cannot turnoff! I am turning off with button! How can I solve this problem
If you have more than one user account, these instructions must be carried out as an administrator.
If you have an optical drive, make sure there is no disc in it.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged during the time something abnormal was happening. That time might be before or after the boot.
For example, if the problem is a slow startup taking three minutes, post the messages timestamped within three minutes after the boot time, not before. If the problem is a system crash or shutdown failure, post the messages from before the boot time, when the system was about to crash or was failing to shut down. In either case, please include the BOOT_TIME message at the beginning or the end of the log extract.
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall or hang logs — they're very long and not helpful. -
Can you figure out what was the problem in this simple 3 liner code?
Hello, below is a class to demonstrate a problem I see that I can't understand. I create an instance of the enclosing
class at class level, another instance in static main method. Class below fails at run time with stack overflow exception. It's all fine if one of those two instantiation steps is removed, What is wrong can anyone any ideas?
public class App
// create instance of this class
App app = new App();
public static void main( String[] args )
// create instance of this class again.
App app2 = new App();
System.out.println( "Hello World!" );
}As soon as a new instance of 'App' is created, 'App app = new App();' is called, which calls 'App app = new App();' etc. Hence the stack overflow.
When you remove 'App app = new App();', obviously, the stack overflow does not occur. And when your remove 'App app2 = new App();' the 'App' class is never instantiated and therefore, the exception is also not thrown. -

Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC. -

Block pop-up windows is not checked in my preferences, yet when I try to play a card game at a yahoo site it won't allow me to join table because it says "please set browser to allow pop-ups to join table". What do I do to join the games then?
Open Firefox -> go to Tools Menu -> Options -> Content section ->
press "Exceptions..." button infront of "Block Pop-up Windows"
-> Type the address of the website you wish to unblock pop-ups from e.g. www.yahoo.com -> Allow -> Close -> "OK" the Options window -
Hi Guys,
I have a problem with Importing Pictures onto my Mac mini with Lion installed by using a Card Reader,
What is the problem here so I can get Pictures onto my Computer. ,Hi Noob Søren
There are a few things that are confusing in your question.
As far as I know, you dont have to install Time Machine on this OS as it is already installed for you. You only need to connect a hard drive to your computer via firewire or usb, click on the Time Machine icon, Open Time Machine Preference in the drop down menu and select a disk: your connected hard drive.
You can of course reformat this connected device, partition it into a few volumes to organise data if you so wish.
I find it strange that your mac's hard drive is divided into two volumes... perhaps this was created through bootcamp?
You can access the configuration of your hd through Applications/Utilities/Disk Utilities.
Clicking on one of the icons on the right hand panel will bring the details of the contents of your hardDrive and volumes. From there you can decide to erase a partition, reformat etc....
If your hd contains more than one volume, and one of them is empty, you could decide to remove it. Back up all your important data before doing so.
Hope this helps

My Imac is ejecting every disk inserted in it, I cannot access the disks, can any body help me troubleshoot the problem. I am using snow leopard.
Try resetting the SMC Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
and PRAM How to Reset NVRAM on your Mac - Apple Support
If those don't help you can try a cleaning disc or a quick shot of compressed air. Chances are that your drive has failed, join the club it's not all that uncommon. You can either have it replaced or purchase an inexpensive external drive. Don't buy the cute little Apple USB Superdrive, it won't work on macs with internal drives working or not.
