Cannot connect to Internet neither Airport nor Ethernet

Have tried many times to correct, do I have to reinstall or restore to factory settings? If so, how? And will I lose all loaded applications and data?

What type of router and modem are you using and have you gone to Network preferences and used the "Assist Me..." button(s) to setup a connection?

Windows cannot connect to internet with airport

I have a macbook with Windows via Bootcamp. I have DSL. My mac OS can access internet fine (wirelessly and ethernet). I can access internet through Windows if I connect directly through the modem (ethernet). If I connect ethernet through airport, I cannot connect. Of course I cannot connect wirelessly either. I would like to connect wirelessly. Any ideas?
Thanks,
Rich

Richard,
Some items to consider.
First, can Windows see the wireless router? You can go under network settings in Windows and see if it "sees" the wireless access point. Or, you can log into the router and see if it sees Windows as a connected device.
Do you have any security enabled on your router? If so, have you set up the security on Windows?
Are you using DHCP on your router? If so, does Windows have a valid IP address?
Also, have you made sure that the device driver for the Airport Card under Windows is current and working properly?

Cannot connect to internet as Airport "has a self assigned IP address"?

I suddenly cannot connet to wireless internet as the Airport has a "self assigned IP address" whatever that is. I have tried removing other wireless connectons but it makes no difference. I'm trying to use the wireless connection at the hotel I'm stying in..its working fine on this computer. Any suggestions ...PLEASE?
Thanks

Hmmm... well, not what I was hoping to find b/c that is not really a helpful answer, l.b, but thanks for joining in on the discussion. I too just experienced the same problem. Yesterday I was connected just fine, a little slow, but connecting just the same. I was able to do my banking, browsing & what have ya. Today I get up and have no internet connection and my computer says it Airport has self-assigned an ip address and I cannot connect to the Internet. I haven't done anything different and as I can tell, they haven't done anything different either. My iMAC will not connect, but this piece of poop del mini will as will my iphone4 and all three of my kids' ipod touches. Soooo.... anyone else have a solution b/c I am totally at a loss here. I really need my iMac to connect. Got things to do that I can't do on here.

Cannot connect to internet through AirPort in Costa Rica - HELP!

Hello,
I have been traveling Costa Rica for the past few days, and have had no problem connecting to WIFI across the country, but, tonight, I am not able to connect. I clicked on my AirPort icon > Open Network Preferences. The Status reads "On", BUT under the status is a message that says:
"AirPort has the self-assigned IP address 169... and will not be able to connect to the internet."
Reading through the posts here, I have tried several fixes...
- Renew DHCP Lease
- Repair permissions
...And still no luck.
I have no access to the router itself, because I am staying at a bed and breakfast. Anyone have any other ideas?
I really appreciate your help in advance. I love this community!
Sincerely,
Nathan

Hey,
This is obviously seems to be a DHCP problem, do you have any other wireless devices with you like an iPhone, iPad or just any wireless capable device ? If yes, try to connect through it and see if it will obtain a valid IP address successfully, if it didn't, then surely it's a router issue that it isn't able to distribute IP addresses, if you don't have a second device, can you see any ethernet connections in the wall ? another solution is to contact the IT person at your location and ask him if you should configure your network settings manually and if so, what would be the settings. Sometimes something as simple as restarting the router fixes similar issues

Pc cannot connect to internet via airport

Hi
I have an older Airport Extreme base station (round pyramid style) that is fine with my Mac (MacBook Air, iMac, iPad-2, iPhone 4+) and other wifi devices.
However, we also have various PC laptops (needed for work) that can connect to the Airport base station (PC= green line from pc to base, red line crossed through to internet Windows graphic) but NOT to the web (?)
We have high speed DSL, and a modem plugged directly into the base station.
How can I set Airport up or the PC laptops, so that the PC laptops can have access to the web and everything stays the same for all of my other stuff?
Very behind in my work...

Hi,
I believe you have the problem that I was able to correct last weekend on my son's pc laptop by updating the atheros wireless adapter drivers. Here are two simple options to test if you need to get an updated driver for the pc wireless adapter. The first is to just connect the laptop to the Airport Extreme with a network cable. If that is not an option, enable the guest network with no security on the Airport Extreme and connect the pc laptop to the guest network. If either method works, the wireless security method is the problem and a new driver was the solution.

Cannot connect to internet with airport

My laptop connects to my network, but does not have internet access--although the main computer does have wireless iinternet access through the airport's wireless connection.

What happens if you power off the main computer completely and then restart the AirPort Extreme and laptop?
Can the laptop connect now?

Cannot connect to internet after airport firmware upgrade

I bought a new Airport Extreme Base Station, hooked it up, and it worked just fine. Then it asked for a firmware upgrade, which I installed. Now the base station will not connect to the internet. I've tried re-booting my cable modem, re-starting the base station, etc. No luck. Pending an answer to this question, I re-installed my prior Airport Extreme base station, and it worked just fine. It wants me to do a firmware update, but I'm understandably reluctant.
Thanks for your help.
Bob

Thanks Chris. One of posts in this thread mentioned the possibility of a corrupt file in the operating system. I reloaded 10.7 using a flash drive I made and then did a hard reset of my Airport Extreme. That solved the problem. I hope this helps.

Cannot connect to internet using Airport

I am having difficulty connecting my new Airport express to the internet. Everything connects fine modem>Airport (WAN) and then back to my computer (LAN) and I get a green light on the Airport but when I open the safari browser it says I do not have an internet connection.

Hello mfort77. Welcome to the Apple Discussions!
It's always a good idea to perform a complete power recycle whenever you change network configurations.
Try the following, in order, checking for Internet access after each step, until resolved:
1. If the modem has a reset switch, use it to reset the modem. Wait at least 5-10 minutes for the modem to initialize.
2. Remove power from the modem. If it has a backup battery, remove this as well. Wait 5-10 minutes. Replace the battery, and add power back to the modem.
3. Perform a complete power recycle of your network components as follows:
Modem/Router Power Recycling - Quick
o Power-off the modem, 802.11n AirPort Extreme Base Station (AEBSn), & computer(s); Wait at least 5 minutes.
o Power-on the modem; Wait at least 5 minutes.
o Power-on the AEBSn; Wait at least 5 minutes.
o Power-on the computer(s)
If this fails to get the modem to "recognize" the Internet router, then try the "Full" version.
Modem/Router Power ReCycling - Full
o Power-off the modem, AEBSn, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
o Power-on the modem; Wait at least 15 minutes.
o Power-on the AEBSn; Wait at least 5 minutes.
o Power-on the computer(s)
4. Contact your ISP to have them perform a "modem reset."

Cannot connect to internet on PC laptops with Airport Express

I had to purchase a new Airport Express today - old one failed. My G3 I Book connects to the internet with no problem. My two windows laptops (Toshiba and Dell ) are showing a strong signal but cannot connect to internet. Can anyone help with advice for settings on these two laptops ? By the way, I had no problem with my old Airport Express and these two PC laptops - need them for work ! Thanks!

Airport problem-cannot connect to internet since update

I like many folks here is new to a Mac. I have a iMac intel duel processor. i apparently did this update to 10/4/8 10/2/06. Since then airport does not work and I cannot connect to internet at all. I have talked to Apple customer service but so far no help there. They want me to reinstall disc that came with computer. I also have a new MacBook that has update also. I can set it beside the iMac in my office and it works great. We have a wirelss system in our home and a PC and the MacBook still connect with no problem. Settings on iMac and MacBook look identical to what I can tell. Nothing I try to connect works, rebooting, change some setting. Can anyone offer easy to follow suggestions to a new Mac user. Thanks

Since it's only the iMac that's having the issue connecting using WPA, we don't need to troubleshoot the router or the other computers.
I suggest trying the following on the iMac before attempting to reload the previous version of the OS.
If you use "Preferred Networks," instead of "Automatic" for your "By default, join" setting Location, try the following:
System Preferences > Network > Show > AirPort > AirPort tab
- Delete all preferred networks with encryption
- Add them again after manually connecting
(Note: It will be faster if you turn on "Automatically add new networks to preferred networks list" under "Options" of the AirPort network connection.)
If this doesn't work, something might have gone wrong with the update to 10.4.8. I would suggest that you follow the Apple Tech's recommendation and reinstall the previous OS using the installation disk that came with your iMac.

When you use the Airport utility what happens?

Wi-Fi Setup Considerations
Things to consider before you begin
Start with a plan for the physical layout. Depending on whether you have an existing Wi-Fi network, or if you are using your AirPort Express as a standalone Wi-Fi device, there are several options available for you to choose from.
When using Ethernet, Cat6 cable is recommended.
The layout you choose should take into account environmental factors such as physical access, location, range, radio frequency interference, etc.
You will need to consider what AirPort Utility settings to adopt.
You will need to know whether you are using an AirPort Express (802.11b/g) or an AirPort Express (802.11a/b/g/n).
If you will be using more than one Wi-Fi base station, it may be helpful to read the article Extending the range of your wireless network by adding additional Wi-Fi base stations.

Lost connection to internet through airport

My Mac at home is configured to a timecapsule and connected through airport wifi. The Time capsule is connected via cable to modem and out via cable to Internet. Up until today everything is fine. started up and i have lost connection to the internet.
Network Preferences is showing that Airport has a self asssigned IP address and cannot connect to internet. The time capsule lights are showing green, as do the Modem, neither are reporting problems.
I have tried all of the "first Aid configurations" i.e. switch off/on etc, also tried a couple of ideas from forums, nothing works. I can connect the Mac directly to the modem via cable and access the internet.
As an aside, My iphone has also lost connectivity through home wifi.
It would appear from other forums that this is a growing problem, however not much in the way of resolution. Any Ideas????

Cannot connect to receiver using AirPort Extreme due to password protection

I have a new AirPort Extreme and Harman Kardon receiver. I am trying to connect the HK receiver to my home network, after entering in all the necessary info (IP, subnet mask etc) I still cannot connect to internet radio, Pandora etc. I called HK and they say it is because my home network is password protected. They recommend I disable to the password and keep it without a password. Is this the only option I have?

There is no reason to do this if your HK receiver cannot connect using wireless, as appears to be the case here. You must have misunderstood the HK support person, or they misunderstood you when you spoke with them.
The information in the manual only talks about a wired Ethernet connection. There is no information that I can find that would indicate that the HK Receiver will be able to connect to the wireless network using wireless.
Unless you can provide another link that would indicate otherwise, you will need to plan to connect the HK receiver using a wired Ethernet cable, or use a pair of EOP adapters to send the signal over the AC wiring in your home.
It would also be possible to use an AirPort Express to connect to the AirPort Extreme over wireless by locating the AirPort Express near the HK receiver and then in turn connecting a short Ethernet cable from the AirPort Express to the HK receiver.

ITunes cannot connect to Internet and iPad backup takes Forever

Hi, I have a workstation, high end Windows 7, PC, everything works perfect except the iTunes.. here's my story:
iTunes cannot connect to internet, nor can iTunes Store. I tried "Run Diagnostics" from Help menu, it showed "internet connection verified" green light BUT "Secure link to iTunes Store Failed" Red Light.
Then I thought, lets check other Apple App, Safari.. which couldn't load google for a long time and didn't even show any error, anyway, so I quit and uninstalled it.
I connected iPad for backup, it started all fine. At "Step 2 of 7" backing up, the loading/copying bar came half way up and stayed there for more than 20 hours. So, I quit that too. (Maybe, this is a different problem or connected, im not sure.)
I also checked the setting in Norton Firewall and made sure iTunes was allowed full access. Internet is working perfect in all the other applications, even "Apple Software Update" is working fine, checking for updates and everything. I have latest version of iTunes by the way.
THEN, I uninstalled everything Apple, left no trace of Apple in Program Files, and reinstalled iTunes. STILL SAME PROBLEM!!! Can anybody help? What could've happened, 'coz it used to work just fine before.
Thanks Guys!

start itunes.
update podcasts - no response.
click on store - no response.
use diagnostics for connectivity - no response.
sometimes, when i stop itunes from trying to connect, i will get an error code 11222
