Why can't my MacBook Air connect to Internet?

I'm at my Dad's for the holidays. I normally connect my MacBook Air to his Wifi router without any problems. But now I can't.
Here's what I do to connect:
Apple icon>System Preferences>Network>Choose his network name>Assist me>Assistant
This gives me the Introduction window with a present location name. I click Continue. The "I use AirPort to connect to the Internet wirelessly" radio button has been selected by default. I click Continue.
I select his wireless network name and put in his password.   The "Ready to Connect" window comes up and it tell me I am ready to connect to his network. I can see the wireless icon in the upper right corner of my top window pane searching for the signal. At this point in the past, this is where it has locked onto the signal and given me Internet.   But it gives up after a fews seconds and I get a greyed-out exclamation point.
I click Continue and I get a new window saying, "Unable to establish a network connection."
So I don't know what to do. I use his laptop to connect to the Internet wirelssly without any trouble. I have tried connecting mine sitting right by the router with no luck. As I said, in the past, I've had no problems connecting.   As far as I know, nothing is different with my laptop and nothing is different with my Dad's setup.
Does anyone have any good ideas? Troubleshooting?   Thanks.

Hold down the option key and select the Wi-Fi menu in the menu bar. What values are shown for the following?
PHY Mode
Channel
Security
Signal/Noise or RSSI
Transmit Rate
Please do not post the BSSID, as that information is private.
Now hold down the option key again and select
 ▹ System Information... ▹ Network ▹ Wi-Fi
Compare the two-letter Country Code with the ISO code for your country. Does it match? The code X0 means that the country couldn't be determined. The code X3 means South America, not otherwise specified.

I can download and open pdfs on my macbook air. Why can't I open a pdf from a webpage?

I can download and open pdfs on my macbook air. Why can't I open a pdf from a webpage?

Back up all data.
Triple-click the line of text below to select it, the copy the selected text to the Clipboard (command-C):
/Library/Internet Plug-ins
In the Finder, select
Go > Go to Folder
from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens (command-V), then press return.
From the folder that opens, remove any items that have the letters “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari, and test.
The "Silverlight" web plugin distributed by Microsoft can also interfere with PDF display in Safari, so you may need to remove it as well, if it's present.
If you still have the issue, repeat with this line:
~/Library/Internet Plug-ins
If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari again.

Can the MacBook Air work with any other type of internet connection beside wifi?

Can the MacBook Air work with any other kind of internet connection besides Wifi?

Who? ITS VERY important when doing a restore, in fact you DO NOT want to do a wifi restore
The pros all have that Ethernet adapter,... that should tell you something. An Ethernet restore via that "thing" makes restoring the OSX about 8X faster.
Its called a Gigabit Ethernet adapter for a reason.
"who the heck" is anyone working with their Macbook Air at home and want a MUCH FASTER download / internet connection.
*Stockbrokers who pack their Macbook Air, arrive at work and plug that "hardwired" dongle to their Air........ because even seconds in the stock market can make the difference between losing a million $$, or making a million $$
So now you know WHY,.....before you didnt.

Why my macbook air is eating up so much megabits from my internet connection?

Is there anyone out there who can explain why my macbook air is eating up so much megabits from my internet connection, despite the fact that ı'm not using the internet?

Any client on a network, including wireless clients you don't know about, could be consuming bandwidth. Wi-Fi networks must be protected with WPA2 security. If yours isn't, change the security setting on the access point. If it's already set that way, change the password. Make it a string of at least 8 random characters, including digits and upper- and lower-case letters. The password is saved in the keychain and you don't have to be able remember it; in fact, you shouldn't be able to remember it.
You make these changes in AirPort Utility, if the access point is an Apple device, or in a web browser otherwise.
If the network or the password was insecure, and bandwidth use returns to normal after securing it, you can be pretty sure the problem was caused by intruders.
But intrusion may not be the issue. Most often BitTorrent, iCloud, Dropbox, or some other cloud-data application is involved in cases of mysterious bandwidth use by a Mac. If you use iCloud, uncheck at least Photo Stream and Documents & Data in its preference pane and see whether there's any change. If you use third-party network backup or file-sync software, disable that. If you use a torrent client, remove it.
Otherwise, if you're running OS X 10.9 or later, you can see which processes are most active on the network.
Launch the Activity Monitor 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.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select All Processes from the View menu, if not already selected, and also select the Network tab.
Click the heading of the Sent Bytes column in the process table to sort the entries by bandwidth usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Repeat with the Rcvd Bytes column.

Hi, my MacBook Air is not working anymore if it's not connected with the power cable. It's pretty new so I can't imagine that the battery is dead already. Why can't I use my MacBook Air without the power cable even though I charged it for hours?

Macbook air can't go to the internet when connected with hard disk

Hi, so my macbook air can't go to the internet everytime when it is connected with my hard disk. The wifi icon on the top right corner says my macbook is connected to my wifi but my macbook just can't go to the internet. I unplugged my hard disk and I have no problem connecting to the internet right away? I would like to know if there is any solution for this problem.
Thank you

Try resetting your SMC.
Resetting the SMC of an Intel-based portable Mac with a battery you should not remove on your own
Note: This will not delete any data.
The SMC is responsible for controlling various system functions. None of your data will be deleted by resetting the SMC.
Shut down the computer by going to Apple () > Shut Down…
Select Shut Down or allow the computer to shut down automatically.
Plug in the MagSafe power adapter into a power source and then connect it to your Mac if you have not already done so.
On the built-in keyboard, press the (left side) Shift (⇧), Control (⌃), and Option (⌥) keys and the Power Button at the same time.
Release the (left side) Shift (⇧), Control (⌃), and Option (⌥) keys and the Power Button at the same time.
I hope I helped.

My macbook air will not connect to the internet due to a self assigned IP address. I have tried trawling the support forums, but either I can't understand the suggestions, or they don't work. Please explain to me in simplest terms how to fix this. Thanks!

HT5395 why can't i use my imessage on my macbook air

I'm trying to imessage someone from my macbook air to their iphone. but it said i am unavaliable?? why can't i send imessages anymore???

Hi,
The iMessages account in Messages does not list itself as Unavailable.
AIM, Jabber and Yahoo accounts via their Buddy lists (if shown separately) or the combined List can show as Off line.
The iMessages Account seems to presume the computer will be on all the time and be connected to a Network continually like an iPhone is.
It does not indicate when a Contact is Off Line or Unavailable until you try to send an iMessage when it might pop up an alert to say it was not delivered. (Most likely when a iPhone has lost a Cell/Mobile service coverage as well as WiFi).
Can you explain what you are seeing and where ?

Installing on Macbook Air 4,2 - why can I not get this done?

I am trying so desperately to install Arch and dual-boot on my Macbook Air. I'm not an Arch noob - I promise. I've installed and loved arch on my old laptop a couple years back but that was not a mac.
I've been here but all it says is that this "works out of the box". Unfortunately, I can't get that far.
I flashed Archboot to my USB thumb stick using DD and booted into it using ReFind. I can't remember what the first option was, but I believe it was Arch-something with EFI. I chose that and I got an error message:
Failed to open file: boot\intel-ucode.img
Trying to load files to higher address
Failed to open file: boot\intel-ucode.img
So, I chose the second option which says (I'm sorry, I'm in my OSX right now so I'mg telling this from memory) something like Arch-something without EFI. Then I got to the actual install console. I created some partitions using cgdisk and chose my packages but they all failed to install due to a dependency missing. I'm really sorry I don't know what that error was. After I post this I will go back and try again and see if I Can get a screen shot.
Anyhow - This is nothing like my install was on my old PC laptop and I feel like I'm not even sure if I'm going down the right path. Does anyone know of a youtube video which shows this process? Honestly, as much as I've used Arch in the past, I truly feel like a dumbass right now but I'm willing to risk my reputation for a rig that runs the sweetest Linux there is.
Thanks -
Whatever you need, logs, etc... no problem - but tell me where to get them because I'm not sure how to with my system in limbo like this.

Alright, only problem is that the beginner's guide talks about entering things at a prompt - like "# sgdisk --zap-all /dev/sda". i'm not at a prompt. I'm in the GUI Archboot console. Also, I don't see instructions on which partitions to create, what size to make them, etc.. and, I still don't know why the original option in Archboot failed - the one that prompted me that it could not find boot/intel-ucode/img. It's not that I haven't read the documentation and it's also not that I'm too stupid to figure it out - I feel like I'm on the wrong track. For example, the Beginner's Guide doesn't even mention instructions for Archboot - which is what I'm using. By the way, thank you for your response. I don't want to sound ungrateful

After upgrading my iPad Air with IOS 7.06, I could no longer connect to the internet.
I have 2 MacBooks Air, 1 ipad mini and one iPhone 4S running on the same network, and they are all connected to the net and function well.
So I cleaned up the ipad completely, installed the latest firmware and reinstalled my apps : no connection.
I tried all things of resets and forgets. No result.
I have been fondling with my Airport Extreme 5 , but that did not help much.
This morning I went to a neighbor , hooked my ipad air on his network, typed the password and the thing all worked fine.
I have tried to connect the ipad air as an ethernet client, but that did not work. „Not enough power“ was the statement
Ideas anyone ?

Yes I tried this manyfold. But did not work. Reading on, I took Tesserac's advice. Shut down router and computer.
Start router after 15 minutes and wait another 10 minutes before starting the computer.
Et voila.... everything is back in working order,

Why can't my macbook pro / macbook air read FAT32 external hard-drive?

I have a USB external hard drive that's formatted as FAT32. It worked fine under Windows and Ubuntu Linux.
here is what it shows under ubuntu:
Disk /dev/sdc: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x3a39bfa1
   Device Boot      Start         End      Blocks   Id System
/dev/sdc1            2048   976773119   488385536    b W95 FAT32
As you can see its file system is FAT32, and as I understand FAT32 read/write is supported on all MACs.
However when I plug it to either a Macbook pro or a Macbook air, it said:
The disk you inserted was not readable by this computer.

How can I get Windows Internet explorer on my MacBook air?

I have several websites that I need to use for my new job that have not been tested for Mac. I don't want to have to buy a PC laptop, so I was wondering if there is a tried and true way to get windows Internet explorer on my MacBook air.

Or install Parallels 7 and then you can run IE just like any other app from within OS X itself. That costs around $50 plus the Windows license though.
Personally I have created an IE9 RDP (remote) App on my terminal server at work and just run that. Looks like it is running on my Mac natively.
