My mac book air will not connect to the Internet

I have a late 2010 MacBook air which has been connecting to the Internet by wifi until very recently. It now connects to the wireless router but not the Internet, there is a alert saying there is no Internet connection. My iPhone and iPad both connect to the Internet so I don't think there is a problem with my Internet connection.

Ok then.
Would you like to give the forum some more details?
If not then there is very little anyone could suggest.

Reset the TC to factory and start again.
Use all SMB type names for wireless and base station.. Not apple type names.. this is more important since Mavericks.
I also recommend different names for the different bands.
So for example.
TC name.. TCgenx (I use whatever the generation number is for the x.. eg TCgen4 or latest one TCgen5)
WIreless name.. TC24ghz for 2.4ghz
TC5ghz for 5ghz
You can also set the channel manually.
If you still have issues.. start with no security and then if it fails to connect there is something seriously wrong with the laptop. Did you upgrade install Mavericks?? That can lead to driver issues.. I would recommend a clean install.

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!

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

MacBook Air will not connect to the internet

I am trying to assist my wife with her Macbook air (MbA), it will no longer connect to the "internet". BACKGROUND: I am running Century Link DSL Modem, with a Belkin Wireless router. I have about 10 different nodes on my home network, PC, Apple and Droid devices. All of which have no issues with access to the internet. My wife's MbA however will not access the web, it does however connect to my network and get a DHCP assigned IPv4 Address from my network. I am able to go to addresses and inside my network and serve up http such as my router's web page. WHAT I HAVE TRYIED: I have flushed/removed all previously connected wireless networks on the MbA and turned off wireless on the device then shutdown and restarted it and reconnected to my SSID (wireless network) = no joy, didn't work. I have rebooted all of my network equipment = no joy, didn't work. I have changed the DNS to an address outside my network = no joy, didn't work. I don't know alot about Mac/apple product, they seem simple and straight forward, and I have been a cisco routrer/switch jockey for about the last 7 years of my carreer.... this one stumps me. Any ideas? Firewall configuration, is there a "intranet" only box checked somewhere?
PS... I may have miss spelled my words, human communication matters, spelling is over rated.

I have OS 10.8.2 and use wireless at home just fine.
When I visit a friend with only a cable modem internet my Mac Book Pro will not connect.
I see that the Mac Book Pro is picking up the internet when I check the internet preference section but it will not open Safari.
What do I need to do connect via a cable modem?

You need to power off the modem for 15-30 seconds, then power back up and then connect. The modem is remembering the last connection (your friend).

My new mac book air will not show old emails. how can i fix this problem

my new mac book air will not show old emails. how can i fix this problem

The answer depends on a number of factors, such as the following:
If you have more than one email account, does this problem affect one, some, or all of your accounts?
Where did you last see this mail -- in your Inbox(es)? in some other folder(s) outside your Inbox(es)? somewhere else?
How old is the missing email -- yesterday? just before you got the new computer? over a week? over a month? over a year?
How are you reading email -- with the builtin Mail application? with some other mail-reading application? with a web browser?
How do you access your email on the server -- IMAP? POP? Exchange? web browser? other?
What version of OS X is on your new computer -- Mavericks (10.9.x)? Mountain Lion (10.8.x)?
Did you migrate your data and applications from your old computer when you set up your new computer?
For example, if the missing mail is the mail that was in your Inbox before you got the new computer, you are reading it with the builtin Mail via POP, and you failed to migrate data, then the mail was left behind on the old computer. The same would be true if the mail was in "On My Mac" mailboxes and you failed to migrate data.

Macbook air will not connect to the wifi network

I recently had to replace my wireless network router and now my macbook air will not connect to the network. it worked fine with the old wireless router. Now, i get a "unable to join wi-fi network" message. The network ID (SSID) and password (WPA) are the same as before. I try to manually enter the password, but continue to get the previous message.
Any help in figuring out how to correct this problem is greatly appreciated.
Also, I have several PCs in the house that have had zero problems connecting to my wireless with the new router. What am I doing wrong?

Hi,
Ever since did the last airport utility update this has been happening.
I believe the airport utility update is solely a software update. Repair permission and repair disk (boot from your installation disk A) may help.
Other wise, http://osxdaily.com/2009/12/22/mac-wireless-problems-guide-to-troubleshooting-ai rport-wireless-problems-on-your-mac/ may help, too.

Which OS are you using (update your user profile).Try a
SMC RESET

Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
The 5 second timing is important to a successful reset.

My imac and ipad2 will not connect to the internet with Windstream using an 2wire DSL modem.

Help my brand new imac and ipad2 will not connect to the internet with Windstream using an "2WIRE" DSL modem. Windstream tech service is useless. i can connect with the built in router through Ethernet or wireless, but still no connecting to internet, help! windstream said everything is working on their end, yea right. What i do know is that both the mac and ipad work at other places and can connect with wireless connected to the internet, so i know it's not the apple products.
these are brand new machines with lion.
This is my first mac, so I’m still new to how it works, which is not helping either so a detailed help would be great. Please help before my wife losses it
thanks

There is a 2701HG-B, and a 2701HG-D. If not labelled on the modem, ask Windstream which one they presently supply or how to tell the difference.
By the way tell your wife it isn't that bad. At least you have an ethernet DSL modem. There were times where DSL modems had RJ-11, USB, and Ethernet, and all three were used to provide access. At least now only the craziest DSL providers still use those modems.

My macbook pro is connected to wifi but it will not connect to the internet.

My macbook pro is connected to wifi but it will not connect to the internet. When I go on safari, it says that "Safari can't verify the identity of the website". Then I tried to update flashplayer but you need the internet to update it. All this only started happening after that Moutain Lion software was downloaded onto the laptop. Please help, I have been internet-less for a couple months now.

Hi rynhelp,
If you are not able to connect to the internet after installing Mountain Lion, see this article for information on how to start troubleshooting:

You may find additional troubleshooting information in this article useful:

It is written for Lion but works for Mountain Lion as well.

TS1492 When I go to iTunes and then check for updates. I can not do this action due to the fact iTunes will not connect to the internet although the internet is working just fine, what do I do to fix this issue? Apparently I am currently using iTunes 7.0.

If you're really using iTunes 7.0 you are very far behind the current version - maybe it is trying to connect to a decomissioned server. In fact I am kind of surprised it will run on a Macbook Air. Are you sure you are running iTunes 7?
