IMac will not connect to wifi says self assigned ip?
I cannot connect to the Internet with my iMac. I just get the message that my wifi has a self assigned IP and so will not connect. Any solutions to this?

Back up all data before making any changes.
Step 1
Take all the applicable steps in this support article.
Step 2
If you're running OS X 10.8.4 or later, run Wireless Diagnostics and take the remedial steps suggested in the summary that appears, if any. The program also generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. Continue if you find that Wi-Fi is faster with Bluetooth disabled.
From that same menu, select Open Bluetooth Preferences. If the box labeled Discoverable is checked, uncheck it. Click the Advanced button, and in the sheet that opens, uncheck the top three boxes, if any are checked. Click OK. Enable Bluetooth and test again.
If the application called "Bluetooth Setup Assistant" is running, quit it.
Step 4
This step will erase all your settings in the Network preference pane. Make a note of them before you begin, and recreate them afterwards. It may be helpful to take screenshots of the preference pane.

from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.

IMac will not connect to Wifi or recognize Ethernet cable
I have an iMac running on OS X. All of a sudden I cannot connect to WiFi...and the computer will not recognize an ethernet cable plugged in. It's wierd...the Wifi will recognize networks in the area. I'll see mine, click on it and it'll ask for the password. I put in the password and it says it's incorrect (The password is defiitely correct as I have several other devices hooked up via Wifi). It wont recognize an Ethernet cable pugged in. It just says one isnt plugged in.
I did aquire a new modem/router recently (Ubee from Time Warner Cable) but no other device is having any issues...including a brand new 27" iMac...among several other devices working fine on the WiFi.
Any suggestions are appreciated. ThanksFirst I would try Safe boot.
1. Shut down Mac
2. Start mac holding 'Shift' till you see the apple logo
3. Log in holding 'Shift'
4. Test there
5. Reboot
Also I would follow the steps here to create a new location:
http://support.apple.com/kb/ht2712
This will create some default network adapters and see if you can connect again -
I installed an Extreme in place of an old Express, the various phones and Ipads seem to work on the WiFi but the Mac itself will not connect. It says something about the IP address being used by another device. Second wifi network was also created. The Mac worked for a few minutes and then gaev up citing eth IP problem......any clues people??
If you have not already done so, now would be a good time to perform a complete network power cycle.......to give everything a fresh start.
Power off every device on the network.....computers, printers, hard drives, etc......in any order that you want
Wait a full minute
Start the modem, and let it run by itself for 2-3 minutes
Start the next device connected to the modem and let it run a full minute
Keep starting devices one at a time about a minute apart until the entire network is back up
Check the network -
IPod Touch 4gen will not connect to wifi no matter what
My white 8gb iPod Touch 4gen will not connect to wifi, I have reset the network and the entire iPod. When I got it for Christmas 2011 it worked perfectly for a few months then all of a sudden it stopped connecting, every connection I try to connect it to says the same thing; unable to join network... I am getting fed up, my first gen iPod Touch will connect to the wifi no problem, but the thing is it keeps crashing. I can't use it for more than a couple of minutes and it goes back to the home screen. If anyone could help, it is greatly appreciated!
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on the router
- Reset network settings: Settings>General>Reset>Reset Network Settings
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Mac OS X will not connect to wifi, airport is broken, will connect to internet with ethernet cord. Is there an accessory I can buy to replace airport so I don't have to use ethernet cord? Please help!!
Since the MacBook Pro currently works, you should put it next to the iMac and compare the network settings for AirPort in System Preferences Network pane Advanced. Also, if you want to start off with the default network settings, you can use Location drop down menu and select +Edit Locations+. Then click the plus sign to create a new location. Set up that new location.
On System Preferences Network pane, AirPort should appear at the top of the list (in the sidebar). To change the service order, click on the gear icon and select +Set Service Order+.
Some additional tests you can try, on top of seeing if it works with (1) WEP security disabled and (2) a direct wired connection to the router.
If you get it to work with either (1) or (2), be sure to run Software Update at least two times to apply any recent updates from Apple. See if that makes any difference to using AirPort with WEP back on.
(3) Start up in Safe Mode
http://support.apple.com/kb/HT1455
I don't know if any third-party software has been installed on the iMac at this point, but Safe Mode will start up with only the essential Apple extensions and processes running. See if it works any better in Safe Mode.
(4) Create a new admin user account in System Preferences Accounts pane
http://docs.info.apple.com/article.html?path=Mac/10.6/en/8235.html
Log out and log in to the new account. Try connecting with AirPort in the new account.
(5) Connect the MacBook Pro to the router with a wired Ethernet connection. Make sure its Internet access works. On System Preferences Sharing pane, set it up for +Internet Sharing+ so that it is set to +Share your connection from Ethernet - To computers using AirPort+. On the iMac, try to connect to that wireless network and access the Internet.
That last one (5) may be a good one to try first. It would at least show that the iMac's AirPort is working - you can even set it up to use WEP. If you have any questions about using the +Internal Sharing+ feature, please ask. -
My 6 day old touch will not connect to wifi .
My 5 day old touch will not connect to wifi. I have reset everything. Tried different networks. I am willing to do a full restore but because I have no internet I can't turn "find my ipod off"
It worked when I first opened it then it kept disconnecting. I reset "all network setting" and rebooted my router and it would connect. Now it will not connect at all
On my ipod it finds the network and when I try to put in password it say "incorrect password"Then restore the iPod using the following
Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
iOS: Forgot passcode or device disabled
If recovery mode does not work try DFU mode.
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: Back up and restore your iOS device with iCloud or iTunes
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
If problem what happens or does not happen and when in the instructions? When you successfully get the iPod in recovery mode and connect to computer iTunes should say it found an iPod in recovery mode. -
My iMac will not connect to time capsule used as base station in my roaming network
I have a network that is made of up a Time capsule as a base station and 3 airport express's used to extend my wifi coverage. It is setup as a roaming network with each express hardwired to the base time capsule. I have a iMac that will not connect to the base station, it will only connect to one of the remote express's. The iMac is next to the base satation. Other mac notebooks, iPhone or iPads all connect to the base station when they are near it. Only my iMac will not connect to it. Any suggestions as to why this is happening or steps I can take to fix this.
Hello FoxFamilyVA
Check out the first article below to go through some troubleshooting options to get your iMac to connect to your Time Capsule. I would go through and remove it from the list of known networks that you join and then add it back in. I would also recommend that you try and create a new Network Location to see if there is an issue with your current configuration.

I updated an iPod touch, an iPad 2, and an iPhone 4 to iOS 6, and all of them now will not connect to WiFi. They all give this wierd 404 error page from Apple and insist that I need to login to the network. What's the fix? None of the recommended fixes work in any of these devices. Reset device, reset network, renew lease, etc. None of them work.
Does the iPod work OK?
Does it charge when connect to the computer?

Look at the dock connector on the iPod. Compare with the iPod that does work/connect.

Hi jazznola9,
Welcome to the Apple Support Communities!
There are several steps you can take when troubleshooting Wi-Fi connectivity on an iPhone and it sounds like you have already done a few of them already. In your situation I would recommend reading over and working through the steps listed in the attached article.

Please take a look at this Apple support document to see if it help solve your issue:

Can anyone help? My wireless connection is working on both my iphone4S and my ipad2, but my Imac will not connect to the network.
First run Software Update to make sure your iMac is up-to-date.
Even though things are working OK on other devices there may still be issues with your modem or router so it's best to start there. Locate the manuals on both devices and reset each. Do the modem first then the router. Next make sure the router has up-to-date firmware. If the problem continues after updating resetting and updating both devices then download and install iStumbler and let it run for about 30 minutes. iStumbler will scan your area for the Wi-Fi networks being used, pay attention to the channels each network is set to. Most routers are pre-set to channels 5 or 6 and if you are in a congested area and all the routers are set for channel 5 or 6 then you can see where there might be a problem. Set your router's channel to one not being used in your area, you have at least 14 channels to choose from. Also check to see if your router is using 802.11n, if it's not then it would be wise to upgrade the router to a faster device.
Next is if you are still having issues the problem could be your ISP's DNS settings. If you want to learn about DNS please read CNET's DNS Article and MacWorld's DNS Troubleshooting . Then use the instructions below to reset the DNS settings:
1. System preferences
2. Network
3. Click Advanced
4. Click DNS tab
5. Click + sign
6. Add 208.67.222.222
7. Click + sign
8. Add 208.67.220.220
9. Click OK.
10. Exit System Preferences -

Have you tryed to restore the iPhone too ?
Restore the phone in iTunes using a backup, and if needed as a new iPhone, without using a backup. However, the greyed out WiFi is often due to a hardware failure requiring replacement of the phone.
