IMac suddenly refuses to connect to the internet...? What?

Hello, everyone.
Yesterday I ran into quite a pickle, and have yet to get out. I was on the computer just about all morning, and got off. The internet was working fine, and there were no issues at all. However I hear, shortly after I get off, my older sister complain that the internet was out.
Being the tech-y of the house, I immediately responded to her issue. However, usually it's a simple fix, correct? Either the router is messed up, and I just have to restart it/go to the router's page and turn it on from there, or just simply connect the Mac back to the internet connection... however it lacked that simplicity.
I've been trying just about all day, to get this working. I'm completely stumped, and that's all I really can say about it. I'm currently running in BootCamp to access the internet, meaning it's not my router, or the computers ability to connect, it's the Mac side itself, and that alone. Was there a flawed update that was released? Because this Mac is just about as up to date as you can get. We have a mini-mac downstairs, not as well updated, and it's able to connect just fine, all the PC's in the house can connect, just not the iMac...
This was random, too. Like I said, I was on it all morning, and the suddenly it just stops working...
I'd appreciate any help, and I do mean any help. As long as there's a possibility of getting my computer fixed, I'm all ears.

On the Mac open System Preferences->Network pane and turn off the Airport card. Then while in the Network pane highlight the Airport in the left hand corner and near the bottom of the left hand side of the pane and click on the - button. Don't panic!
Lastly while still in the System Preferences->Network pane hit the + button and re-add the Airport card. In the right hand of the pane hit the 'Apply' button and then try to rejoin the wireless network.
Another trick in the Network pane is to make a new "Location', calling it whatever you want (i.e. Home), and hitting the 'Apply' button.
One of these tricks might help. Good Luck.

My iMac won't stay connected to the internet, even though all other computers in my house stay connected

My iMac won't stay connected to the internet, even though all other computers in my house stay connected, and its connection is set up the same way my fiance's macbook is (his macbook is about three years older than my iMac). Every time my computer goes into sleep mode and I come back (even if it's mere seconds after giving the black screen) I have no internet connection. I discovered a workaround for it some time ago, but now that is working less and less, and now my computer randomly disconnects WHILE I'm actively using the internet. Just a few minutes ago, the connection refused to come back until I restarted my computer, even though once again all other computers in the house were connected. The workaround I discovered before and which doesn't work as reliably now, is to click opne Airport at the top right of the screen, click "Open Network Preferences," then click "Assist me," then click "Diagnostics," and wait for everything to turn green again, signalling a connection.

Let's check the quality of your connection since signal strength alone does not insure a good connection. The "bars" that you see at the top of the iMac screen are there pretty much for show.
Hold down the option key on the iMac while you click on the Apple icon at the upper left corner of your screen and select System Profiler
Look down the list of items at the left of the window until you find the setting for Network, then click on AirPort.
In the window to the right, look for any listings of your wireless network name. You may possibly see two listings for the wireless network name.
We need for you to list the information that you see for Signal / Noise. These will be negative numbers. Post back with your findings and we will continue.
In the meantime, please move any cordless phones that you have or any other electronic devices that are near the iMac as far away as possible from the iMac.
If the iMac is located in a corner or an enclosed area, give it as much room as possible since the wireless antenna is on the back of the iMac and it needs to be able to "see" the room.
Anything that you can do to minimize the number of obstructions like walls or furniture etc between the iMac and the wireless router will help the cause as well.

My iPad Mini with retina display suddenly will not connect to the Internet. It shows full wifi bars, yet no web pages will load. My Internet is working with all other apple devices in my house. The iPad also no longer works with celluar data.

My iPad Mini with retina display suddenly will not connect to the Internet. It shows full wifi bars, yet no web pages will load. My Internet is working with all other apple devices in my house. The iPad also no longer works with celluar data. I'm not sure what has happened. It was working fine a few hours ago. I have tried resetting it, ive restarted my browser etc. I tried to erase all data from my Ipad but I can't do that because it needs to sign into my Apple ID and use the Internet!

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
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 http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are drooping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

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.

Macbook Pro suddenly will not connect to the internet via ethernet cable.

I know this is a long shot... but I figured I would give it a try.
My macbook pro suddenly does not connect to the internet via ethernet cable. Please bear with me, as I am not very tech-savvy - I will try my best to describe the symptoms!
I connect to the internet via ethernet (we don't have wifi). It was working before I went to work, and when I came home I suddenly couldn't get anything to work (I know everyone says this, but I truly didn't mess with anything). Internet browsers just think for awhile and then turn up the 'You are not connected to the internet' error.
I went into my network preferences and curiously, the 'Ethernet' shows a green dot and says 'connected'. However it says 'Authentication server is not responding' underneath the last part that says '802.1X: WPA: eduroam' (I think that is my user profile).
When I go into my 'security' settings I can see that my firewall is off, so that shouldn't be causing any problems.
I've tried restarting the router and computer itself many times. Diagnostics just gets to a certain point and reports back 'Network Diagnostics cannot fix the current networking problems.' I've also tried switching to a different ethernet cable, and I tried both cables out on a PC laptop and it connected without issue. Additionally, I brought my macbook along to a friend's house and it connected to his wifi just fine, so the problem appears to just be with ethernet connections.
I know it's hard to troubleshoot this kind of thing without being there and having a look at the computer yourself, but any tips wouild be greatly appreciated.

As I mentioned above, I am not very tech savvy so I have no idea why a wireless protocol would be showing up there, I'm just listing everything I see in hopes that someone might know something I can try. This is why I am asking for help here - I'm not sure what has happened that has made me unable to connect, especially since it seemingly occured while nobody was using the computer.
I guess I should clarify that I'm not a total hillbilly- normally my firewall is set to 'on', but I set it to 'off' to try and troubleshoot the issues here as I was told that sometimes it can interfere with the computer's ability to connect to the internet. If this is not the case and firewall does not affect anything, I will turn it back on while I try to fix this.
I have tried the method you mentioned above a few times - I actually contacted my ISP earlier this week and they recommended resetting the router like that. They didn't mention any known network issues.

If you are the only user on your computer you probably don't have multiple user accounts set up and can disregard that. If you are using iTunes 11 go to View>Show Sidebar. Now see if your iPad appears under Devices on the left side when you connect it. If it does, click on the name of your iPad on the left side and your iTunes sync settings options will appear in folders with tabbed headings to the right.
If it doesn't appear on the left side, follow the troubleshooting steps shown in this article: http://support.apple.com/kb/TS1538.

WIFi needs to enabled and you need to be connected to a network. Alternatively, you need Cellular Data to be "on". (Settings>General>Network). But it propably is a problem with your router (at least, it often is with me), provided you are using your private router. Try schutting it off and turning it on again. This usually sorts problems like this out.

IMac Can No Longer Connect to the Internet

My parents use a 2006 Intel Core Duo iMac (the 17", 1.83GHz model) running OS 10.6 (Snow Leopard). They typically connect to the internet using a wireless network set up using an Airport Extreme with RCN as their ISP.
As of yesterday, the computer can no longer connect to the internet, while all other computers in the house, both Mac and PC, still can. I've tried power cycling the modem and the router, connecting using ethernet, and connecting the computer directly into the modem. Thus far, none of these attempts have succeeded. I've taken a look at the network settings for the computer and while networking is most certainly my thing I wasn't able to detect a change. As a last ditch attempt I tried using Google's public DNS service, rather than RCN's default, but that made no difference, so I've reverted it.
I realize that the information available in this thread is almost certainly too little to guess at what the problem might be, but I'm more than happy to fetch information that might be helpful in finding a solution.
Thanks for taking the time to read the problem; hopefully there's an obvious solution.

"Drive is dead????" what in this thread gives you that idea? What card might be failing?
Agent: do you have any Input Managers (might be called Input Methods) either in the Home Folder/Library or in the HD/Library (not /System/Library.)
Yes, do try another Account and test for this there.
I know you've already tried Google DNS, but try OpenDNS
You don't need to go to the OpenDNS site to use OpenDNS. Simply open Network>Advanced>DNS in Sys Prefs and enter the following numbers for the interface you use, e.g. Airport or Ethernet,
208.67.222.222
208.67.220.220
Hit OK and then Apply. Make sure those numbers are entered above any others you may have there.

Suddenly unable to connect to the internet

hi all,
my mac's been working fine the past 4 years, when suddenly, a couple of days ago, i turned it on to surf the net, thats when this peculiar problem occurred..
i went onto firefox, typed in a url, but the browser is unable to load anything from it. tried other urls, same thing. tried using safari, same. i restart into this windows partition in the same computer, and i can surf the net as usual!
i connect to the internet via a wireless router that links to an adsl modem, so i try to access my router via its IP address while running mac os, and okay, the browser manages to load the router's webpage. after some fiddling around, i discover that i can actually load websites if i enter their IP address, but not urls, so the problem is most likely something to do with the dns. but the thing is i use the same dns under windows, and it works (and still does). i try using google public dns of 8.8.8.8, and it still doesn't work in mac, while in windows it works perfectly. tried turning off the firewall in mac, no improvement.
what is wrong with my mac?!
oh btw, i think one day before this happened, i just did a software update that gave an update on iLife, but can that actually cause this problem?? didn't change any other setting other than this as far as i recall..
let me know if any specs are required and i'll post them up.. thanks in advance guys!

Hi jf_element and welcome to Apple Discussions!
It sounds like this is an issue with Domain Name Service. Possibly your Internet service provider changed some settings and didn't tell you or possibly your settings have been corrupted.
Go to your *System Preferences* (under the Apple menu) and select Network. Select AirPort from the list of ports on the left. Click the Advanced button. In the resulting dialog box, click on the DNS tab. Is anything listed here? Contact your ISP and ask them for the IP addresses of their domain name servers. Those IP addresses should go here.
Best of luck.

HT1695 why would my new computer with windows 8 set up fine and now all of a sudden I cannot connect to the internet on my IPaD

I have a new computer an Dell Inetel Celeron 2020 with Windows 8. I had interent connection on my old desktop and to my Iphone and Ipad, however now I cannot get my Ipad to connect to the internet whatsoever. i have messed with this since Wednesday of last week and I am exhausted from it. Please help.

So just the ipad cannot connect to the network? Does it connect to any other network?
Try this:
Reboot ipad by pressing and holding both the home and sleep/wake buttons at the same time until the apple logo appears on the screen, then let go. Then try to connect to network.
Go to settings, turn wifi off. Toggle airplane mode on/off. Make sure bluetooth is off. Turn on wif (airplane mode off). Try to connect.
Go to settings/genreral/reset/reset network settings. Then try to connect to network.
If its your home router, then reboot router by unplugging for 5-10min. (do this while you're resetting network settings).
If problem persists, then check for firmware updates on your router.(you check router manufacturer suppot website for downloads and instructions).

1st edition Ipad suddenly won't connect to the internet.

My ipad was working fine online until I turned it on the other day and found it would not connect to the internet. I instantly went into the settings, the wifi section in the system preferences is greyed out. I have reset it via iTunes and it still does nothing, its like it has no inbuilt wireless capabilty at all. Its nothing to do with my internet as all my other devices are working correctly. It just does not recognise anything. Help!

Its always worked fine, its the first time its happened, and seems to be for no clear reasons, I have reset the ipad, reset the wifi etc, connected it to iTunes. I have also tried pressing down the on button while holding sleep and it does nothing. Its got no wifi symbol either. In system pref, it says No wifi, so I can't click on that. I have then gone into genral to the VPN and it says not connected. When I press on it ask for information to add a configuration, but I have tried putting info in there, although not entily sure what to add in some of the requests it want sin order to save the pref. I just do not have a clue. Other than thinking it needs a new card installed, but can you even do that on a iPad, I did this on my Macbook.
Thank you.
