AirPort does not have an IP address and cannot connect to the Internet.

Wi Fi problems
I have recently changed from a old netgear router to using a vigor 120 modem with airport extreme
Internet connection is established but my airport express reports "AirPort does not have an IP address and cannot connect to the Internet." although status is ON and the correct wifi address appears.
My iPhone also identifies the correct network but cannot connect
Any suggestions?

I don't have any phones, so not aware of the options, but on a Mac to fix this problem it'd likely be...
Instead of joining it from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed. Before I went through network diagnostics and all of that stuff in system preferences, and then I tried the "Join Other Network" method, and now it works like a dream.

Or...
Go to System Preferences
Click Network
Highlight AirPort and click Configure...
Choose “By default, join: Preferred networks”
Select your access point and Remove your access point with the minus button.
Launch your keychain access in Utilities and delete your access point keychain entry.
Reboot

MacBook has self assigned ip address and cannot connect to the internet.

Is there an Apple recomended fix for this problem that works? I've looked on this board and have found several similar suggestions but as yet nothing that results with consistent connection every time I restart.

Since there is no exacting way to tell what of several suggestions offered in
these discussion boards, you may have tried, I will offer an Apple Support
article name and web address link; it may be you have tried this:
• Mac OS: How to release and renew a DHCP lease
http://support.apple.com/kb/TS1920
And you can get a similar self-assigned IP address via a wireless network
or a wired local network - with a theoretical connection to the internet. If
the actual connection in software is not set correctly, the default will likely
be something very familiar since the same one appears then.
If the Network system preference panel is set and you have chosen the
mode of connecting to the internet or other connected network, then
you can set the configuration of that choice in a secondary screen. In
order to have a choice to connect via AirPort, for example, you have to
check box the item and also drag it into a position of priority (first.) Or,
if you have to connect via Ethernet to a cable/DSL modem (if not USB)
you can choose to place Ethernet in a position of priority above others.
Then, further the Network configuration's next step to set it up correctly.
The above link does cover the basics adequately, including a reset of
the cable or DSL modem. If there is a cable modem and also a wireless
base station, you may also have to reset each of them in a specific way
in order to get them to start up and work. This may be all it takes.
Good luck & happy computing!

I have Windows XP / bootcamp and can connect to the internet via Wi Fi (Apple Express) but when I try to open Int. Explorer I get a message "cannot connect". I checked to make sure IE is not off line. Any suggestions please?

Try using a different browser as a test.

My iphone 4s keeps saying it does not have enough icloud storage and cannot be backed up. When I go to icloud storage and backup, it says that I have 5.0 GB of total storage and 5.0 GB of available storage.

My iphone 4s keeps saying it does not have enough icloud storage and icloud cannot be backed up. When I go to icloud Storage & Backup in my settings, it says that I have 5.0 GB total and 5.0 GB available. The only thing I have selected, at this point, to be backed up are my contacts and the Find My iPhone app. Why does it always say I have no icloud storage available when I have ALL of the icloud storage available?!

It says that my next backup size is 7.3 GB, but I have no idea why, because the only thing selected is the Find iPhone app, which takes up 0.2 KB...How do I get rid of whatever it THINKS it's backing up?

ITunes does not recognize my iPhone when I am connected to the internet!

Okay, I am back with an old problem that I had with iTunes 9.0. iTunes will not see my iPhone if I am connected to the internet. If I turn off the WiFi, I am fine. Is there a fix for this? I found the following (see below) on 1 website and did all of them already. I don't have # 3, so I did not have to try that one thing.
Run through this series of potential fixes, which will solve sync issues for most users:
1. Reinstall iTunes. In some cases this issue can be resolved by completely removing then reinstalling iTunes as described in this Apple Knowledge Base article.
2. Remove third-party backup software. If you’ve installed software for an external hard drive or another device, it may include an automatic backup utility that recognizes the iPad as a storage device, interfering with the normal sync process. Try uninstalling any such software then re-syncing your iPad.
3. Remove iToner. It appears that the presence of Ambrosia Software’ iToner software may cause problems with syncing the iPad. Navigate to ~/Library/iTunes/iTunes Plug-ins and/Library/iTunes/iTunes Plug-ins (the Library folders inside your user folder and at the root level of your startup drive) and look for a file called iTonerSupport.bundle. Remove it, then restart, and check to see if iPad syncing occurs more quickly.
4. Delete iTunes .plist. Delete the following file
~/Library/Preferences/com.apple.itunes.plist then restart

try deleting these preference files
•C:\Documents and Settings\Your Username Here\Application Data\Apple Computer\iTunes
•C:\Documents and Settings\Your Username Here\Local Settings\Application Data\Apple Computer\iTunes
•C:\Documents and Settings\All Users\Application Data\Apple Computer\iTunes\SC Info

Just received my T530 and cannot connect to the internet

I just recieved my T530 laptop on Friday, 8/26. Right out of the box, I am unable to connect and sustain any internet connection. I have my other PC tried on two different wireless routers and it works fine. It is not the routers that is the issue.
My computer says I am connected to the internet but I cannot browse. I have enabled the Intel connection under properties. The drivers are all up to date. I have restored the system to factory settings because a Lenovo tech support rep said the Windows update was messing new laptops up.
All of this and I still cannot connect to the internet. I am a wits end. What do I have to do to get this working? Also, how do I return the laptop for a refund?
Thanks!

ladiel,
Typically support will ship a box overnight to you for you to send the system in, and in most cases repairs at the depot are 1-2 days and then it will be shipped back to you overnight.
If you wish to return, you will need to call sales, and let them know you had a defective system and provide the service case number (where you called support to verify your trouble)
I appreciate your time urgency on this.

Restore from iphone4 itunes backup stops after upgrade to ios6. does it have to do with my computer settings as it starts hanging and cannot connect to the internet anymore either till I restart.

I have the latest version of iTunes and the iOS6 installed on my iPhone4. The restore from my iTunes backup stops at the end of the recovery process though. Do I need to change anything in my computer settings to let it totally finish?

I recently upgraded to 10.5.8 from 10.3.9. I have a Powerbook G4. All was working well with no problems until I upgraded. Initially, everything was still working fine then after about a week it stopped connecting to the internet both wirelessly and via ethernet. It was down for about 2 weeks when I started to 'play' with the settings. I don't know what I did, but it worked again. The computer stopped working again about a month ago and I just am now getting to it. I don't know what else to do and why it stopped.

I have AirPort Extreme and cannot connect to the internet with a land line but the WiFi works

I have an AirPort Extreme and have been using for several months successfully, but as of two weeks ago, the line that I have hooked up to my desktop no longer provides internet service, but the WiFi works fine for the I-Pad and I-Pod.
I have checked with my service provider and my modem works successfully hooked up the the AirPort extreme or directly to the PC. When I am hooked in from the modem directly to my PC, I have internet for my desktop, but of course no WiFi.
If I connect the Modem to the Router and the router to my desktop, I have WiFi, but no internet service to my desktop.
I have replaced the network cable but to no avail.
Any suggestions?

It appears that there may be something amiss with the Ethernet switch that is built-in the 802.11n AirPort Extreme Base Station (AEBSn) or its configuration settings may be incorrect. I assume that you also tried using the other LAN ports on the AEBSn and the outcome was the same ... no Internet access via a wired connection.
One thing to try is to change the Ethernet adapter settings on the PC. It is possible that its current settings may be appropriate when connected directly to the Internet modem, but may be off for connecting to the AEBSn. If your PC's Ethernet adapter has options to control Speed, Duplex, & MTU, I would change these to the following respectively: 1000 Mbps, Full duplex, & 1500

Connecting to Time Capsule via ethernet but my computer does not have an IP address

I'm connected to internet w/Airport TC.
I want to connect via ethernet for fast and stable backup. When I connect the ethernet cable what I see is "The cable for Ethernet is connected, but your computer does not have an IP address". I don't want to mess up with my connection. What should I do?

Thanks for your response Bob, I found a way to resolve my issue.
I'm connecting to internet via wireless modem. TC is connected to that wireless modem via wired ethernet connection and functions as a router - I guess - so our Apple devices connect to the network.
I had disabled WiFi earlier, since I wanted to connect to TC via ethernet. I realized I somehow needed to have the connection re-enabled WiFi but change the connection order, so ethernet is at the top of the list.
It might have been some other things I did, like trying to imitate config samples I found on the net by typing 255.255.255.0 and 192.something.something.0...etc.
Not sure exactly what made it work, but eventually, I believe I managed to connect and transfer many gigs of data over to TC with ethernet but it still took soooooo long.
Thanks,

"Server either does not have a virtual switch configured or none of the configured virtual switches have an IP address assigned" error driving me nuts!

OK; have been trying to setup a test VM based RDS deployment for a few days now with no luck.
this error mentioned above:
"Server <server name> either does not have a virtual switch configured or none of the configured virtual switches have an IP address assigned" error is driving me nuts!
I have removed and re-added the RD Virtualization Host role numerous times, each time having the "create a virtual switch" checkbox selected, but it did NOT create any virtual switch.
I created the external virtual switch manually and tried to create the desktop collection again, no luck with the same error.
a few questions:
1. you don't assign IP to a switch! you assign IP to Network Interfaces. why does the error puts it like this?! it is technically wrong.(yeah yeah I know all about how you'd assign IP to managed switches in real world to telnet into them and manage them.
you know better than me that it is not the case here!)
2.the RDS Virtualization hosts are using their wifi card as the card for the virtual switch. could that be the reason? I even disabled their unplugged wired NIC just to make sure that the wifi is the only available option for the RDS wizard to use for the
virtual switch creation; but it didn't use it and it didn't create any virtual switch automatically.
3.if WIFI nic is indeed the reason, is it your suspension or an official documents is there somewhere stating so (that the WIFI NICS on a Virtualization hosts are not supported as the hub for a virtual switch).
4.what are the properties of the virtual switch the RDS requires? does it have to be external? why can't it work even with my manually created external switch?
5.how would I fix it?
P.S: the environment is made up of 2 laptops, having windows 2012 R2 trial installed on them, using their wifi to connect to the out world. no cable is plugged into their wired NIC card.

Hi,
Thank you for posting in Windows Server Forum.
The simplest short term solution was to connect each computer to a small switch that had no other connectivity. This brought up the link light on the external NIC and allowed the creation of the collection to complete. You need to use an external switch. You
can create one external switch which might fix the problem.
Please check below article for information.

In addition please referthis article for information regarding virtual switch.
Hope it helps!
Thanks.

When updating to ios 7, my airport does not function in my ipad and iphone. No icon appears...I´ve check I´ve got last firmware on aiport utility, and also I´ve restart both devices... thanks for your support..

Restart your AirPort Base Station or other router if that's what you have. Unplug it and allow a moment or two for it to reset before plugging it back in again.
If that does not work, try resetting your network settings: on the iPad and iPhone, tap Settings > Wi-Fi, select your network then "Forget this Network". Select the network again, provide its password, and verify you can connect.
If that does not work, Settings > General > Reset > Reset Network Settings. Select your network again as above.
If that does not work, "hard reset" your AirPort Base Station, assuming you are using one and not some third party product. You will need to reconfigure it using AirPort Utility.

My Netbook that my phone is sync to does not have a cd drive and I want to put my digital copies onto it

My Netbook that my phone is sync to does not have a cd drive and I want to put my digital copies onto it but I do not know how to, I have a laptop I can put the disks in but I don't know if it will let me copy the file to a flash drive any ideas? also I keep getting this message about updating my media player security and when i go to the site it links to the update button is greyed out and will not allow me to do it

If you import the CD on your laptop with a disc drive, then you can place the music files on a flash drive and transfer them over to your netbook. You could also choose to email the music files from the disc drive laptop to yourself to download them onto your netbook through your mail account.
As for your second question, is it windows media player you're trying to update? Try downloading the latest version of WMP to see if that resolves the issue.

Recently updated to itunes 10.6.1, but during update it says itunes does not have a valid signature and update fails ,now older version is not able to connect to itunes store error 306. I am using windows 7.

(Apologies for butting in, wha.)
now older version is not able to connect to itunes store error 306. I am using windows 7.
If you still get the 306 after updating to 10.6.1.7, perhaps try the following user tip:

My airport is not connecting to the internet. I have a cable modem. and i'm on the internet now connected directly to the modem. what can i do?

my airport is not connecting to the internet. I have a cable modem. and i'm on the internet now connected directly to the modem. what can i do?

I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Continue with step 2 in the first set of steps.
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

AirPort does not have an IP address and cannot connect to the Internet.
