No internet connection after migration of profile

I just migrated an os x 10.68 user profile to a fully functional install of Yosemite. Now, while the system gets an IP address from my router (an airport extreme), I get the message - "not connected to the internet" whenever i try to browse the web. I can't send email either.
The machine is a late 2012 21 inch iMac with 4 GB of ram and a 1 TB hard drive. It was working fine before I did the migration. I have 4 other macs and various iOS devices working on the same wifi network - without problems.
By a process of elimination I think I probably overwrote a key file or something similar. Any advice on how to proceed? My next step is a reinstall of OS X using the recover volume (command - R on reboot). Anything else I should attempt?
Thanks in advance for the assistance.

Apple programs will not recognize Internet connection after Tiger upgrade

In January, I posted the question below. I wanted to update it, but this site has archived it and will not allow responses. In the hope that I may help someone else, I am repeating my question, now that I have the answer.
===============================================
ORIGINAL PROBLEM
Last week, I upgraded from 10.3.9 to Tiger. Ever since then, I have had trouble using Apple's programs that require internet usage: Safari, iTunes, Software Update, etc. All of these programs think I am not connected to the Internet. But I am; I can use Netscape, Internet Explorer, and other non-Apple programs on the web.
Furthermore, it's not consistent. Sometimes Safari will recognize the connection. I'll be using Safari, looking up websites, when suddenly it will quit connecting, giving me the message, "Cannot connect to the server," no matter what server it is, even apple.com (so I have to use Netscape to access my .Mac and this Support screen).
How can I resolve this?
==============================================
The problem was that my Earthlink Access software was setting a proxy on my connection. Netscape & Firefox worked because they ignore any proxies; the Apple programs (plus Shiira and Internet Explorer) didn't connect because they use the proxies.
Why did it sometimes work? Well, if I first used Safari to go to a secure website of my bank, somehow that opened up the connection and then I could continue to use the Internet and Internet based programs like iTunes and widgets. However, if I tried to use an Internet-based program before going to the secure site, then it wouldn't work.
After months of phone calls and e-mails and sending data packets and all such stuff with Apple Care, they finally stumbled upon this answer: Uncheck the proxy box. And that did it. At first I had to uncheck it every time I started up the computer, but now it stays unchecked and I can use my Apple programs with no trouble.
I just wanted to share this with you in case you also had trouble with Internet connections after upgrading to Tiger, because I did see several other people had this same trouble.
Movable flat-screen iMac G4 Mac OS X (10.4.6) 1.25Ghz processor, 256 MB memory (DDR SDRAM)

For the record, could you state each Proxy box you ended up unchecking please? I'll attempt to submit a user tip with credit to you for finding this solution.

MBA loses internet connection after waking from sleep

I have a new Macbook Air running Mavericks and new 802.11ac Airport Extreme router.
My problem is that the MBA drops the internet connection after waking from sleep. I tried the solution offered by the OP, but it didn't work.
In my case, here's what I have to do to get a connection again. I open the Network preference pane, and then choose "Assist me..." and then "Diagnostics". Invariably it will show a green light beside Wi-Fi, Wi-Fi Settings and Network Settings. I have 5 bars showing in the WiFi menu bar icon. But ISP, Internet and Server will be yellow.
When I go through the steps prompted by the wizard, the ISP/Internet/Server lights turn green on the third screen where I select the wireless network I want to join.
It seems as if it's connecting to the WiFi network when it wakes from sleep, but losing the internet connection?
Note: I have a new iMac as well running Mavericks and don't have this problem with it.

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.

I'm having problems with my internet connection after installing OS X Lion. Is this a known problem or just a local problem?

I'm having problems with my internet connection after installing OS X Lion. Is this a known problem or just a local problem?
After +/- 10 to 15min my connection is gone.
Does anyone have a sollution?

Lots of people are having the same problem, you're not the only one, belieeeeve me.
Just Googling the problem gets you tons of people complaining about the same thing, SOMETHING is up with Lion what wasn't happening with Snow Leopard. i just bought a new Imac and it CAME with Lion, so i started experiencing this internet dropout immediately.
It's been going on for the most of a year it looks like (at least by the dates from the threads i've been reading)
So your best bet is to fiddle with the System Preferences and read what other people have used to make theirs work. i'm doing that myself right now. I already posted a similar thread last night trying to figure out why my connection kept on dropping, i got a reply which linked me to a site. i followed the instructions there, so far so good, but i'm just being cautiously optimistic.
i'm gonna call Apple today and see if they've found anything, though seeing as this is a problem right out of the box there may not be an immediate solution. Good luck hunting for a solution :3

I've lost internet connection after a power outage; how do I restore?

I've lost internet connection after a power outage; how do I restore?

Check with your internet provider for help. Your modem or router could have been damaged if they did not come on after the outage. If your modem and router look OK all you should have to do is restart your iMac.

IMac keeps on loosing internet connection after a few minutes...

Intel dual core iMac with 10.6.8 OS keeps losing internet connection after a few minutes. Need to put it to sleep and bring it up again. Than it works again...for a few minutes. Other equipment like laptops and iPad using same wifi internet connection and have no connectivity problem at all... What to do?

Then what I suggest that you do is go to the Finder and select Mac Help in the Help menu. In Mac Help go to Index>C>Connect to the Internet. There you can read all about configuring your Mac, using a modem, etc. After you better understand how all that works then come back with your questions.

Lost internet connection after installing BT dongle (MS-6967)

I have tried installing the MSI Bluetooth USB dongle (MS-6967) drivers twice. I tried the 1.3.1 version and the 1.4.2 version drivers. The Bluetooth dongle itself works fine, but both times I lost my internet connection after installation. After this I have to remove the drivers and repair my installation with the Windows CD, but then windows and all of my programs also need to be updated again since my original Windows CD is a first release version.
The weird thing is that I can connect to other local computers and I can even ping external computers, but browsing websites (on IP address), looking up domain names and retrieving mail are no longer possible. I have no firewall software installed.
Does anyone konw how to fix this?

Am I really the only one with this problem? Well I have seen someone else on another forum ...
Maybe someone knows how to reinstall just the TCP/IP stack?
I'm using a notebook with buil-in network card. It runs W2K dutch version SP4 and things worked before when I was using SP1. Somehow it doesn;t work now anymore. Before I start reinstalling everyting again, I just want to check once more if anyone has some tips for recovering.

Anyone having trouble with internet connection after downloading mountain lion

After installing Mountain lion to my mid 2011 imac 21" I am having trouble with my internet connection. Anyone else have to deal with this?

Are you on 10.8.2 as ypur profile says? If so, it's worth updating to 10.8.3 which was released last week.

Loss of internet connectivity after upgrading to windows 8.1

Hi, After upgrading to windows 8.1 from windows 8 i am experiencing major problems , loss of internet connectivity for no reason both I.E. and G/CHROME are now taking an age to open there are no virus issues as far as i can see.
I have uninstalled and re-installed windows 8.1 about four times over the past 9 months or so and the same thing happens after all the updates are in it runs like a dream for say 6weeks or so then i get the same faults as described above then i uninstall/ re-install ok for 6 weeks .
I would apprieate any help or advice thanks

Hi @BMATH
Thank you your query.
I understand that after updating to Windows 8.1 about every 6 weeks you loose wireless connectivity for no reason and the web pages are very slow to open. If you uninstall and reinstall Windows 8.1 it works fine again for about the same amount of time. You have done this about 4 times with the same result each time.
Do you know if there is any changes at that time , perhaps an update?
You stated you do not believe you have any viruses. Just to be sure here are two links that will help confirm that.
Microsoft Malicious Software Removal Tool
Microsoft Safety Scanner
After updating to Windows 8.1 have you checked for Windows updates?
Have you ran HP Support Assistant ?
Here is a link to Troubleshooting Wireless Network and Internet (Windows 8) that may also help.

Problems with your internet connection after upgrading to iOS 7.1.2

2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

WiFi self assigned IP and no internet connection after OS & iTunes upgrade

I have two likely related issues that started as a direct result of upgrading to OS X 10.8.5 and/or iTunes 11:
Starting tonight, after upgrading my OS and iTunes I am no longer able to use Home Sharing between my iMac and Apple TV. Apple TV is logged in to my network and Home Sharing is on, on both devices (signed in to the same account), but Apple TV says Home Sharing is not connecting to my iMac. My iPhone 5 is also not showing a Home Sharing connection.
I've restarted both my iMac and Apple TV several times. Logged in and out several times. Turned Home Sharing off/on several times, power cycled and reset my network modem once.
While trouble shooting my Home Sharing connection I noticed that under my Network settings, Wi-Fi is yellow instead of green and reads "Self-Assigned IP... Wi-Fi has the self-assigned IP address xxx.xxx.xxx.xx and will not be able to connect to the Internet.".
When I go back to Apple TV I've found that althought it's connectted to my iMac through WiFi and I can see my purchased movies I can't view them becasue there is no connection to the iTunes Store (no internet coinnection through WiFi). But my actual network connection on my iMac is just fine.
So it seems that my new OS or iTunes upgrade has caused my WiFi to no longer allow an internet connection across teh wireless network.
Can anybody here tell me why that would happen and how can I fix it?
Any help is greatly appreciated,
David

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.
Triple-click the line below on this page to select it:
/Library/Preferences/SystemConfiguration
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
Go ▹ Go to Folder...
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.
Step 5
Reset the System Management Controller.
Step 6
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
*An SSD doesn't need to be zeroed.

Re-establish internet connection after restarting laptop

I have a wireless router (WRT54G) and to make an internet connection to my laptop I must use a cord and establish the connection, then that cord is removed. However, I must do this everytime I turn my computer on/off or restart it. When I first purchased the laptop, router, and adapter I only had to establish the connection once and had no problems with connecting to the internet even after I restarted my laptop. What is wrong that I must re-establish the connection with each restart?

okay... hardwire the computer directly to the router, logon to router's setup page, open I.E. and in the address bar type 192.168.1.1 it would ask for username and password, put "admin" (default password) as a password without any username…click on wireless tab and try changing wireless channel to 11, click on advanced wireless settings reduce beacon interval to 50, fragmentation and RTS threshold to 2304… make sure that you have latest firmware installed on the router… also tell me the model and version no. of the adapter that you have and OS on computer…

All browsers lose internet connection after awhile

After upgrading Safari and Java yesterday, all of my internet browsers are losing connection after awhile (10 - 15 minutes), until I disable and enable Airport. However, when the browsers are dosconnected, the airport connection is still ok, because Mail stays connected. The disconnection in the browsers happens randomly.
So if 1 browser suddenly disconnects, all the other browsers cannot connect either. Mail stays connected. Browsers only connect after I disable and enable Airport
I tried the following stuff:
repair disk permission
maintenance
cleared java's cache
rebooted osx a few times
reseted router

Hi Tim
What does your Application/Browser log say in 'console' ?

I lose internet connection after shutting down

I lose my internet connection whenever I shut down my desktop. I know it's not my modem or router because laptops, iphones and ipods all have a great signal and connection. This only started happening after I downloaded the latest software update 2 weeks ago. I have a Motorola modem and Apple extreme router.

last two days exactly the same - it states that my network is not available and yet shows it, I then have to re enter the password, also date had reverted back to Jan 1st, however, there was one bonus, scrole on the mouse now works correctly again!

No internet connection after software update

Yesterday I did for the first time my Nokia E51software update. I followed after instruction, update has installed properly. After update I backed up my data and settings. But there is one problem. After update my phone lost internet connection. Everytime when I try to go to the internet my phone is connecting Vodafone Live, but after that always appears error - Web: connection time out.
I wanted setup internet settings here, but I see that Nokia doesn't do automatic setup anymore Hell, how it was helpful and handy!!!
I was also on my mobile provider's (Vodafone) website, but they doesn't have any manuals for this kind of Nokia like mine.
Do you have any suggestions what should I do?

If you have done a full backup in PC Suite, then do a fresh Restore but this time uncheck the Settings options and just restore the others.
It is usual that settings may change after a firmware update.
