Internet connection and firewall
I have seen several other posts on what appears to be my problem, but I have not seen an answer, so my apologies for trying again. I had service done on my MBP recently and they altered the network settings at the Apple store. When I got home, I set them back to where they had been, but I have had a recurring problem ever since - if I have shut down or been disconnected for awhile, my computer refuses to connect to the internet.
I normally keep the firewall set to "Set access for specific services...". To make an internet connection, I have to go to the firewall and select "All all incoming connections". Once the connection has been made, I can change my firewall back to its normal settings with no issues. I no nothing of the inner workings of the Mac OS, but does the initial connection require that some utility program be run with the firewall turned off in order for the connection to be established? If so, could it be added to the firewall's allowed application list to prevent this back and forth with the firewall settings?

If you had services done which you had to pay or are covered by the APP at the Apple store, you should have received a receipt at the time you got your mac back. If you are not happy with the service... look at the bottom of the page, it says how many days you have to make a claim (either 30 or 90 days).
You can take your mac and your receipt back to the Apple store and have them fix your problem for free as long as the problem you have now is derived from the old problem...
As for OS X apps that need internet access, that would be the clock time servers, any dashboard apps...mmm... Do you have MSN or any other programs which may need instant internet access?
(I am guessing here... since it is hard to tell since it depends what you have in your setup...)

Can anyone help with setting up my CC tells me to check my internet connection and firewall settings which are ok. I have a PC
my internet connection and firewall settings which are ok.
Most likely not, but since you haven't provided any proper system info and other technical details like what internet connection you actually use we can't advise specifically. Start by reading this:

I just installed the CS6/CC applications I use without any issue. I then was prompted to install various updates. All the updates failed and the message says the downloads failed. I checked my internet and firewall settings and they are fine. I the was able to install a different CC application I hadn't installed before. That process worked fine so I retried all the updates. They all failed again and for the same reason. I have even tried a cold system reboot. Nothing works. I am really baffled.

Im at a loss here, even switched cables thinking that would help. no luck either
Cpress1 please see Error downloading Creative Cloud applications - http://helpx.adobe.com/creative-cloud/kb/error-downloading-cc-apps.html for several possible solutions for your current download error. I would also recommend looking at any software firewall or security software which you have installed that could be interfering with the download process.

Photobook order stops after preparing files due to Internet issue and firewall. I couldn"t correct
Photo book ordering stops at preparing files. Says I don't have Internet connection and or Firewall is blocking Elememts. I turne off firewall and my internet seems ok.
You have Acrobat Pro on your system. It will try to open PDFs, and of course it will fail. You must uninstall it. Then, you will need a PDF reader. So install Adobe Reader. That seems quite simple, but perhaps something is wrong. If anything goes wrong with these two steps (1) uninstall Acrobat Pro (2) install Adobe Reader, then please let us know the details.

Everytime I turn on Outlook, it kills my internet connection and I have to reboot the router
As the title says, each time I turn on Outlook with Office 365, it kills my internet connection and I have to reboot the router. I can still login to the router admin and do a soft reboot. This kills the internet for all the computers on my network as well.
The weird exception to this is when I'm connected to my work VPN, then everything is fine. Also, should be noted, it never did this at first...then started doing it randomly and stopped after a while...now a few months later, it started doing it agian.
Is there some sort of weird port forwarding I should be using?
I'm running through an Exchange server.
Windows 7 Pro
Router is a D-Link 857 - HD Media Router 3000..running latest firmware.
Everything is setup standard. No firewalls except the standard Windows firewall and the router is a really basic config.
Please any insight would be great!
CoreyHello AyaTheBookWorm,
Thanks for using Apple Support Communities.
I can definitely understand how this is frustrating, I would feel the same way. To troubleshoot this issue please see the steps below, as well as checking out the Wireless Diagnostics.
Symptom: The network connection drops unexpectedly
Your Mac may not not stay connected to your Wi-Fi network reliably.
Your Mac may stop accessing the Internet during use.
Solution
Use these steps if your computer disconnects from its Wi-Fi network unexpectedly.
Check your range to the Wi-Fi router and reduce the effect of interference.
If your computer is too far from your Wi-Fi router or your environment has too much Wi-Fi interference, then your computer may not detect the Wi-Fi network properly. The easiest way to check for range limits with your Wi-Fi network is to move your computer or your Wi-Fi router closer together and make sure that there are no obstructions (such as walls, cabinets, and so forth) between the router and your computer.
See Potential sources of wireless interference for more information about interference and solutions.
Try connecting to a different Wi-Fi network. If your computer works fine when connected to a different Wi-Fi network, then the issue may be related to your network router or ISP. In that case, contact the manufacturer of your router or your ISP.

my iphone has an internet connect and can browse safari, and it can also connect to the app store, but wen i go to download anything it says i have to review my account.. so i enter all my details and card details and move on to the next step.. but it says "cannot connect to itunes " and " your request is temporarly unavailable"
Emily,
thanks for your posting, it just reflects my experience (although I didn't contact the helpdesk, but after what you wrote I think I can skip that part). I am livin in China and buy from the German MS, worked fine until about a week ago when the download of an album stopped just after 5 songs. I have never been able to connect to the shop ever since.
The interesting thing is, that I get a response from their server in the domain phobos.apple.com (phobos.apple.com/WebObjects/MZStore.woa/wa/storeFront) which I would interpret that there can't be a problem which they always list (Antivirus, Firewall etc...)
So will there ever be somebody from Apple who is going to give a better explanation how to solve the problem ? Or are there already too many people buying iPods and music ??? -
Using Remote app on iPhone 5 without a separate internet connection and wifi router.
Hi,
I need to be able to control iTunes within my MacBook Pro remotely. Using my mobile broadband service and wireless router I've been able to get the Remote app to allow my iPhone 5 to do the job nicely through Home Share. So I went and bought a separate WiFi router and tried to do the same thing. Of course when it didn't work, I discovered that I need an internet connection and WiFi network to make the Home Sharing work.
So I got to thinking, can I create a WiFi hotspot using the Personal HotSpot functionality of my iPhone, set up Home Sharing on phone and MacBookPro and then use the Remote app. Ideally this would work as it seems all the key components are in place.
The MacBook Pro accepts the iPhone hotspot as a means of Home Sharing, however the iPhone won't use the personal hotspot to Home Share and I can't connect to the iPhone personal hotspot on the iPhone itself.
Does anyone know how to make this work for me? It would be such as neat solution if I can get it to work - not to mention the potential to save me about $200 (I need to set this model up for two people).
Cheers
KathySame trouble here, iPad 2 with latest OS and remote app, iPod with latest OS and app.

Since the Mountain Lion OS update today I've had issues with internet connection and e-mail, has anyone else?
That's what I would have thought, but even after saving the setting, as soon as I shut down my computer or log out of Mail, it automatically defaults back to 25. It's a bit frustrating.
Now I just need to figure out how to get rid of those horrible pop-up banners but still have my glass sound and number of emails in the red dot when I get an email...
These little tweaks are the only thing I HATE about upgrading my OS. -
Background is I can't hook up my time capsule directly to my internet connection via network cable. I tried to extend the network via Wifi, but that did not work. At the moment I have two wireless networks, one with internet connection and another one with my time capsule. So to use time machine I have to change my network all the time.
Can I buy an Airport Express, use is as a client to my internet connection wifi and provide that connection via network cable to my time capsule and all it's wifi clients?The AirPort Express will connect to your existing wireless network if the network is using WPA2 Personal or WPA/WPA2 Personal wireless security settings.
So, it can join the network as a client and then provide an Ethernet signal to your Time Capsule.
Be sure to configure the Time Capsule to operate in Bridge Mode so that it will be operating on the same network. -
facetime stops working after installing mavericks. After login it says: check internet connection and try again. My internet connections are ok, I have both wifi and lan.
Please describe in detail what happened when you took all the applicable steps in the support article. That's the starting point for any further efforts to solve the problem.

I keep getting the same errors with the damn Creative Cloud application on my Windows 7 machine, which IS connected to a LAN and IS actively connected to the internet at the time the error routinely appears in the midst of tasks. I have checked root certificates, manually checked my hosts file and run the tests outlined above to both Adobe addresses.
In fact, the error kept occuring while I was on an over 3-1/2 hour call with a very through and nice representative from Adobe who had remote screen access at the time (through Adobe connect) and could see the error repeatedly occuring!
Her comment, "This just happens sometimes with this application and there's not a patch for it yet", The problem I was having with Photoshop CS6 and Photoshop CC was so severe that I had to do a SYSTEM RESTORE which then started affecting other Adobe applications because Windows had erased part of the programs (or all of some programs) but Adobe's software saw them as still installed, that she had me uninstall ALL Adobe Creative Cloud applications using the Adobe Cleaner Tool and reinstall everyting from SCRATCH. She and I had tried numerous other ways to repair the problems I was having with updates not installing correctly AND constant program freezing, etc. before this taking this extreme step.
I'm a professional programmer / software / web designer, so I had tried for hours correct the issues the previous night and had tried once overnight to reach someone in Adobe support only to be told of over an hour wait time by the automation and not offered a callback.
Anyway, despite her best assistance this afternoon (and double confirmation that everything tested correctly), it has taken, so far, well over six hours to reinstall only a portion of what I need for my work and on a deadline because the application keeps reporting "No Internet Connection" and I have programs cued to install unattended. I am now way behind schedule on some design projects which MUST BE COMPLETED by deadline and require Adobe's software to be installed and function correctly.
Adding to this, Windows Explorer has repeatedly crashed after installing the damn Creative Cloud application and works normally when it's removed and "cleaned" ... and I've seen so many problems with the install system, etc. that I have to wonder what in the hell the company was thinking when this approach was launched?
I generally have liked -- and indeed loved -- some of Adobe's products in the past, but the recent experience has certainly been costly in time and disappointing.
Many other software manufacters integrate suites, perform updates and confirm licenses without such a buggy, time intensive and unreliable process -- including my own company.
Aside from complaining at this point, I wish somebody from Adobe would provide alternative install methods and / or a fullproof fix for this bug and some of the other installation bugs many of us experience. Any thoughts, advice, knowing that not only I -- but also the Adobe Support Staff Person accessing my computer LIVE -- tried the various "fixes"?Branching this to a new discussion as the previous discussion was related to the inability to connect and download the installation software.
Rob it does sound like you are facing some connection and stability difficulties. Do you manage your network youself? I am a bit concerned by the fact that you have stated that you periodically loose Internet connection while completing certain tasks. Does this affect your ability to utilize the already installed Adobe Creative software?
I would also recommend reviewing your installation logs to determine if any errors occured during the installation process. Please see Troubleshoot install issues with log files | CC - http://helpx.adobe.com/creative-cloud/kb/troubleshoot-install-logs-cc.html for information on how to locate and interpret your installation log files. Please feel free to post any specific errors you discover to this discussion thread. -
using Bridge CS5 to exporting to flickr, but get error message "Unable to connect to Flickr, please check your internet connection and try again." please help?
I'm experiencing the same problem. Don't think I can help, but maybe I can offer an explanation. It looks as if Flickr has changed their API and Adobe will need to update the export plugin to comply to get it working again. I found this announcement on Flickr:
