IMac was connected to my wifi, now "no internet connection" works on others
Hi Everyone,
So, I'm using a current generation (I think!) 21.5" i3 iMac. All has been fine, except since yesterday, but, it's a weird problem..
So, I was connected to my home wifi, (a netgear router provided by my ISP), all was well (for the last 6 months or whatever), and then suddenly out of nowhere I have an exclamation mark over my airport sign and "no internet connection" when I click it. (now known as "!")
First thing I tried was restarting router, then restarting iMac. Neither worked, came back and still "!".
Then I realised, my iPhone is on the WiFi and it has been working fine, sure enough it is fine. I got out my old MBP and went on it, and hey, the internet works absolutely fine. So, I started worrying that perhaps the airport in the iMac has suffered some kind of failure...
But, alas no, as I realised some of our neighbours have unprotected networks, so went on a nice "NETGEAR" network, and hey! The internet works on the iMac again. Went back to my network and it comes back with.... "!"
So, I then logically (perhaps) thought that the router has decided to dislike the iMac and isn't letting it connect... So, I reset the router to factory settings (which was a bad idea now that I look back as I didn't have login settings so had to phone call centre of ISP to get details... D'oh..) but now that the internet is back up, I also changed the name of the network, the passwords etc, thinking I could fool the iMac into thinking it's something else, but.. NO! Connected to the new network and.... "!"
So, it's miffing me off quite a lot. I am currently using my Uni's network (which just reaches my flat) but it's not that fast, and not intended for use at home, I'm sure! I'd like to get back on my network.
Any help greatly appreciated but, I realise this is an odd problem.. just hoping I'm not the first?

Take a look at your router settings. If you use WEP encryption, change it to WPA2. Macs really don't like WEP.
Also, here is a good article on all the settings. It references IOS but ignore that:

Im connected to wifi but the internet wont work?
im connected to wifi but the internet wont work how do i make it work
Go to settings, then wifi. There, you can choose a wifi router and if needed, enter the password. You haven't provided any details in your post. Are you trying to connect to a home network? A commercial network?

I have downloaded updates for microsoft office and now the internet wont work - any ideas?
I have downloaded updates for microsoft office and now the internet wont work - any ideas?
If you want to simply do a 'fresh' install (versus wiping out all of your data and doing a 'clean' install) simply boot to your Recovery partition (hold down the Command and R keys whilst booting) and when the Recovery screen appears, elect to freshly install OS X.
Don't know that will solve your problem, though... did you do the 'automatic' update or download the update as a disk image (.dmg)? I wouldn't think that would be causing your problems...

Help! My Facetime and iMessage just totally stopped working on my MacBook Pro - my wifi is still connected and all other apps/internet are working fine. What happened??
Associate your mobile number with your Apple ID, if you haven't already done so.
Sign out of iMessage on the Mac:
Messages ▹ Preferences ▹ Accounts ▹ Sign out
and on the iPhone:
Settings ▹ Messages ▹ Send & Receive ▹ Apple ID ▹ Sign out
Then, on the phone, tap
Use Your Apple ID for iMessage
Sign back into iMessage on both devices and test. If there's no change, you may have to wait for a change in network conditions.

I needed iDvd, but since my iMac is newer, I didn't have iDvd on it. I installed iLife 11. I shouldn't have installed the iPhoto part because now my iPhoto wouldn't work since iLife 11 was 9.1 and my iMac had 9.2. So I used iPhoto Library Manager to create a new library. That was working, but my computer ran out of hard drive room since my original iPhoto had 137 GB of photos. My new iPhoto library had the majority of my pics and the iPhoto now worked with those pics. But now I still had all of those original pics in my hard drive. I thought that by getting rid of the original iPhoto on the iPhoto Library Manager I would get rid of all of those original pics. I now have no access to them but they are in my hard drive and I can't do much with my iMac because it is all clogged up with those original pics - I think. How do I get rid of my original iPhoto pics out of my hard drive?
What system are you running? If it's Mt. Lion go to the App Store and sign in with the Apple ID you used to purchase the Mac. Go to Purchases and download iPhoto again. The current version is 9.4.3.
If you're unable to download iPhoto from the App Store you can reomstall iPhoto from the iLife 11 disk and update it from the Apple Downloads website to the highest version you can get to (I was able to update all the way to 9.4.3 via the updaters). Then if iPhoto can't open the library use iPhoto Library Manager to rebuild it and it will rebuild it compatible with your version of iPhoto via this iPLM tutorial: Fat Cat Software - iPhoto Library Manager Help - Downgrading a library to an earlier version of iPhoto

I just had my logic board replaced. i am now having trouble with using the interent even with a strong connection. all other devices are having no problem with the internet. please help
Test while started in Recovery : if the problem persists, then it likely is a hardware issue.
Resetting the System Management Controller (SMC) probably won't change anything, but you can readily do it before contacting the repairers. -
Help with itunes - was locking up and uninstalled now it won't work at all
Last week, every time I connected my iphone it would lock up during the sync. So this weekend I uninstalled every apple product on my computer so that i could get a clean install. Now, nothing will open. i've reinstalled itunes, etc at least 4 times. It won't open, I keep getting an error message.
"The procedure entry point QTCF_CRUniCharGetUnicodePropertyDataForPlane could not be located in the dynamic link libray QTCF.dll."
What does that mean?"The procedure entry point QTCF_CRUniCharGetUnicodePropertyDataForPlane could not be located in the dynamic link libray QTCF.dll."
That one is usually caused by a misplaced older version of QTCF.dll.
If you've got a 32-bit vista, first look to see if there's a copy of QTCF.dll lurking in your C:\Windows\system32\ folder. If you find one there, drag it out onto the desktop.
If you've got a 64-bit vista, first look to see if there's a copy of QTCF.dll lurking in your C:\Windows\sysWOW64\ folder. If you find one there, drag it out onto the desktop.
Now try launching iTunes again. Does it launch properly this time? -
please help with the above question
Is the wifi optoin greyed out? If so, go to Settings>General>Reset and reset nerwork settings. You will need to reenter any wifi passwords you had previously saved. If that dosn't work, backup the phone and restore it http://support.apple.com/kb/ht1766 this will walk you through all that. Just make sure you setup your phone as new and test the wifi before restoring from backup.

I just upgraded an old Imac from Leopard to Snow Leopard, now it won't work
I just upgraded my 2003 imac from leopard to snow leopard and after restart all I get is a blue screen. Nothing happens. How can I get back to the old leopard. I use this computer for research just because of the 23'' screen. Help
I'm sure that a 2003 machine is incapable of accepting Snow Leopard. Have you checked the specs to see if it is ...
Mac OS X v10.6 Snow Leopard -Read the Technical Specifications
In particular, check the amount of RAM you have.
You could contact Apple through your National Apple store with the serial number of your machine to see if they can provide a replacement DVD ... but I doubt they can.

Hardware - iMac 27 inch (Model 11,1 - late 2009), Processor 2.8 GHz Intel Core i7, Memory 16 GB 1067 MHz DDR3, OS X 10.9.3 (13D65), Storage Capacity 2 TB (Available 1.86 TB)
Background
(1) Me - I'm 72 years young, and am trying desperately to catch up with computer-literate youngsters. Downloaded Mavericks last winter, but then was in hospital, so am only just getting to grips with the further reaches of all the software. One of these is FaceTime, which I never managed to get working before Xmas, and have started to attempt it again now.
(2) The problem - Upon startup of FaceTime (FT), the only thing that appeared in the Right Hand Sidebar (RHS), was a message stating that FT was switched off, alongside a big slide switch, and above both was a spinning wheel (spokes) and the title Preferences. I slid the switch to ON, and the well of the switch glowed a brilliant blue.
I waited for several (perhaps 5) minutes, but nothing changed, the switch continued blue, and the Preferences' wheel kept spinning. There were no other boxes or info in the RHS, so I then checked the FT menu, and found that Preferences was greyed out, and the FT Help pages only described a normal signing in, I couldn't find a trouble shooting section.
So, I decided that the next step was to switch the FT programme off, and then back on again. there was some progress. Now the RHS was showing the signing in boxes. So I filled them in, but got back the answer "Could not sign in. Please check your network connection and try again." Checked the connection, tried a couple of web sites, all appeared OK. Tried signing in again, same result.
Tried creating a new account. That took some time, because my first attempt at an answer was over 32 characters long, and I had to rethink. Once the new answer was typed, a message came up (with words to the effect of) this name is already being used, so it's not a separate account (which I accepted), and the RHS changed to the signing in boxes again.
So I tried signing in again, but received the same message "Could not sign in. Please check your network connection and try again." I tried again a couple more times, but always with the same result. So my Questions are:-
(1) What's happened?
(2) Was it caused by something I did?
(3) What needs to be done (or What do I need to do) in order to get FaceTime working?
Any help will be very gratefully received. Yours

Internet does work on other computers but not on Imac
Hi, after an electricity problem my Imac won't make connection to the internet anymore. My macbook and a Toshiba PC still do.
The Imac finds the network but says there's been a time-out while trying to make the connection.
I called the helpdesk of the internetprovider but they said everything works fine, after having tested the connection.
And of course they don't know anything about Mac...
Thanks for any help.What type of modems and routers do you have? A full make and model workup is necessary to determine the source of the problem. Have you tried connecting directly to the modem by ethernet? And what sort of electricity problem did you have?

Help! I updated to 10.9.1 on my mac and now the internet stopped working!
I updated to 10.9.1 on my mid 2010 macbook (yes these things still exist) a while ago and since then a few strange things have been going on with my computer for example: eventhough I installed an SSD it takes ages to log me in, or sometimes my dashboard decides not to load but the thing that is the most annoying that after about 20 mins or so the internet stoppes working on the app store and all browsers (surprisingly the internet works on games that use it) also if i reboot my computer i have another 20 min window to use the internet. It all started a while ago when i opened safari and it told me that "safari web content could not be displayed" or something like that. Does it matter that i installed the newest flash player shortly before i updated to 10.9.1?
It works. It also gives you lots of options - clone tio image, bootable clone, clone to root, leave stuff in root untouched, etc.
Nice guy who wrote it too.
Basically a front-end to rsync
Before you muck around, at least back up what you have - your files, libraries etc are intact. If possible, then make THAT external drive bootable (put 10.9 on it)

i have att u verse modem and it wi fi was not working. So i got net gear wi fi and connected to att modem . i connected my apple TV via Ethernet cable to att uverse modem . i did not want slow down my wi fi speed. My Apple phone is on Netgear wifi .Now airplay is not working .
Make sure that the Att Modem goes to the netgear router via ethernet cable. Then connect your Apple Tv with a ethernet cable to the back of the net gear router. Airplay wants it to both be connected to the same device, usually.

Internet stops working after being connected for 5 minutes to wifi
My macbook pro running on os x mavericks is giving me an issue. After 5 minutes of connection with the wifi network, the internet stops working even though its connected the network. Reconnecting fixes it for yet another 5 minutes.
Might be corrupted network preferences ..
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following:
/Library/Preferences/SystemConfiguration
Click Go then move all the files in the SystemConfiguration folder to the Trash.
See if that makes a difference.
Your Mac will generate a new SystemConfiguration folder for you.
If that doesn't help, try here > Wi-Fi: How to troubleshoot Wi-Fi connectivity
