Network connect and switching Wi-FI Locations results in no Internet
Machine:
MacBook Pro
OS X 10.8.2
Scenario:
I work at two locations mainly, office and at home during any given week. At both places I VPN in using Network Connect. Let's say I am at home using the VPN on Monday and use it all day. I will then close the computer lid, putting the machine to sleep. Before putting it to sleep I can either sign out of the VPN (Network Connect) or not, either way my issue of no Internet will happen when I get to work the next day. On Tuesday I take my laptop into work, oepn it up an grabs an IP via DHCP, but I have no Internet at all. My machine will have an IP via Wi-FI, but no Internet. My assumption is that my Wi-Fi connection is holding onto something in my routing table from when I was using Network Connect. As of right now my only way of fixing this is to reboot the machine, which if I have items I was working on from the day before, I'd prefer not to.
Couple Things worth Noting:
- If I re-open my laptop on Monday while at home later that night, Internet will work just fine with/without the VPN.
- The scenario will happen when I go from work to home as well, it's just not home to work.
- I am not the only one with this issue
- I should point out that if I connect an Ethernet cable to my machine, I will have Internet without having to reboot. (we do not have Ethernet to our desks, so this is not a viable solution)
What I've tried so far:
- Renew/release does nothing (I already have an IP, but figured it was worth a shot)
- Turning Wi-Fi On/Off (Left machine off for 60 sec)
- Disconnecting from the Network and then reconnecting
- Changed my DNS
- Statically assigning an IP
What fix I'm looking for:
- Fix this issue 100%
- Set of steps to resolve the issue without having to reboot
OK, so I am going to assume my issue was unique and hence the lack of replies. Needless to say it is now working. Hard to say what fixed it, but there are two possibilities.
1. Latest Java update that Apple pushed out
2. Java update form Oracle.
These were both updated at the same time or there of. Regardless this was some bizarre Java issue. Why can;t we live in a word without Java...I sometimes wonder.

Imessage could not sign in. Please check your network connection and try again
Since I updated yesterday I have been wanting to try Imessage on my Ipod Touch 4G, but I keeo getting this message:
imessage could not sign in. Please check your network connection and try again
Any ideas? I checked internet it works in other apps, in email and in safari.
Thanks!Hi,
The Apple ID does not have to be an iCloud listed one.
If you notice in System Preferences > iCloud or Internet Accounts you cannot enable the iCloud account for Messages.
Linc has posted a Starter Document for you to look at.
If you have upgraded from Lion then you could have an issue if your Serial Number is not on your Logic/Mother board.
This should be replaced if the board is replaced through Repair or Refurbishment.
Use the Apple Menu > About this Mac.
Click twice on the line that is the Current OS level.
This will change to the Build Number (Another counting method for the OS) and then to the Serial Number.
This should of course match the one on the back/base/battery compartment of your Mac.
Apple uses this to generate the Authorisation tokens for the app (And FaceTime and the Games Center)
If the Serial Number is Missing you will need to have it installed at an Apple Store or an Apple Authorised Service Provider (AASP)

On March 31, we starting experiencing this issue across our entire domain. We have not made any changes to our network configuration. We are using the same ISP, routing hardware, computer hardware, software versions and group policy settings as we were on March
30.
The issue appears to be related to network connectivity.
Here is what I have found so far:
We have three networks in our building and two ISPs.
Network-A uses ISP-A and is affected by the issue. Network-A is our corporate domain.
Network-B uses ISP-B and is affected by the issue.
Network-C uses ISP-B and is not affected by the issue.
If I take a Network-A domain member and launch PowerPoint while connected to Network-A and ISP-A I am unable to upload PowerPoint presentations.
If I connect the same computer to Network-C, the issue persists.
If I close PowerPoint, connect to Network-C, and reopen PowerPoint while connected to Network-C, I am able to upload presentations.
A non-domain computer is affected by the issue if PowerPoint is opened while connected to Network-A or Network-B, but unaffected if PowerPoint is launched while connected to Network-C. Again, in this scenario, switching connections while PowerPoint is open
has no effect.
The issue appears to be caused during PowerPoint start-up and not while attempting to share a document.
Microsoft is either unwilling or unable to find a resolution and has finally resorted to simply ignoring my calls, voicemails, emails, and ticket requests regarding this issue. Any suggestions would be greatly appreciated.
Here is a brief description of our configuration and what I have tried so far.

So our school lets us use Macbook Airs for the school year, and it has facetime on it. I know facetime isn't blocked because like everyone else is using it. So I decide to give it a try. I click the icon, it says enter your apple ID. I dont have one, so I click to make one, and do so. I then enter my apple ID and click next. The screen reads "People will call you using your email address. What email address would you like to use?" I enter my email address in the box below the message, and then go to my email and click the link, and sign in, thus verifying the email. I go back to the facetime window, and click next. At the top it says Verified, but when I click next it doesn't go on to the next step, it simply blacks out the next button so that I can not click it, and after a few minutes a message comes up that says "Could not verify the email address. Please check your network connection and try again."
So that is the issue, please help!!!!!
*Note-I repeat that I know it is not blocked by the school because everyone else uses it just fine.*Hello BassoonPlayer,
Since you are using one of the the school's Macbooks, it is quite possible that the time and date are not properly set on the computer that you are using. FaceTime will not work if you do not have the proper time zone set up for the location that you are in. This past week, there were a two other Macbook users I've helped by simply telling them to set the Date/Time properly. By the way, you described your problem very well, which makes it easier for us to help you. Hope this solves your problem -- if not, post back and I can suggest other remedies.

Losing network connection and NIC acts weird from warm/hot weather/temperatures?
Hello.
Is there a known issue on MSI P43 NEO3-F (MSI-7514) motherboards' onboard RealTek RTL8168C (P)/8111C(P) PCI-E Gigabit Ethernet NIC network disconnecting and acting weird during warm/hot weather?
I noticed lately and back on 1/11/2009 night when weather got warm/hot (e.g., my room can get over 85F degrees, but lately it has been 80F degrees), my network would lose its connection. See http://img9.imageshack.us/img9/5580/screenshots.gif for a few SpeedFan's sensor readings when the incidents occurred. I have never seen this happen when the weather is cooler (60-70F degrees in my room).
I also think this only happens if I am using the PC lightly (nothing intensive) like watching fullscreen videos (video overlay), surfing the Web, etc. I don't see any errors or evidences that it happens when idled (e.g., asleep or out). Uptime doesn't seem to matter since I have seen days to 3.5 hours.
I tried upgrading network driver twice (e.g., Realtek_XP_5714_0219 from
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false ...), disabling Kerio Personal Firewall v2.1.5 (XP's disabled already), releasing and renewing IP address (works, but still no network -- can't even ping my router!), unplugging and replugging the cat5 cable (do see the network port lights on), touching the network jack and hardware inside and outside of the case (not hot), trying another cat5 cable and a network port on a switch instead router's), changing from "Minimal Power Management" to full power (no underclocking/slowing down when idled), etc.
During the disconnections, I tried:

I also noticed the disconnections usually start with red X icon in my taskbar with its bubble and then later the long disconnection even though no red X (1 GB and connected). If I were to disconnect the cat5 cable from NIC, then it wouldn't even detect it is missing the cable!
The only way to fix this was to reboot (best way and last longer) OR disable network connection and re-enable it (Windows XP's Network Connections) or the NIC itself (Device Manager), but that doesn't always last long (maybe a minute). Example of my pings right after disabling and re-enabling NIC:

Force your NIC to run at 100Mbps full duplex and see how it goes.
Check your router / switch ports as well as cables.
I will try 100 Mbps if it happens again. So far, it hasn't occurred after installing the driver supplied by MSI's Web site and not RealTek's Web site. The room temperatures even got warmer like 83F degrees.
As for router and switch, what am I checking for? Other computers didn't have any problems. As for cat5 cables, I already tried another one like I said in my original post. -
"iMessage Activation. Could not sign in. Please check your network connection and try again"

My iMessage will not let me sign in. The error message "Please check your network connection and try again" keeps popping up. I am connected to wifi.
Welcome to Apple Support Discussions,
Have you tried:
Turn FaceTime or iMessage off and then back on in Settings.
Launch Settings by tapping the icon on the Home screen
Scroll down to Messages or FaceTime
Toggle the switch from on (green) to off (white)
Wait a minute
Toggle the switch back to on (green)
Wait for it to re-activate
Hard reboot your iPhone, iPod touch, or iPad
Make sure you're on Wi-Fi
Hold down both the Home button on the front, and the Sleep/Wake button on the top of your device
Wait for the Apple logo to appear
If it still doesn't work, repeat step 1 (turning FaceTime or iMessage off and on)
Reset network settings
Launch Settings by tapping on the icon on the Home screen
Tap on General
Scroll all the way to the bottom and tap on Reset
Tap on Reset Network Settings
If it still doesn't work, repeat step 1, then step 2, above (Turning FaceTime or iMessage off and one, rebooting).

Facetime error "Could not sign in. please check your network connectivity and try again
When I try to log in to Facetime on my iMac, it gives me the an error. "Could not sign in. please check your network connectivity and try again" I have already tried fixing the time and I dont have any firewall installed
This could be a complicated problem to solve, as there are many possible causes for it. Test after taking each of the following steps that you haven't already tried. Back up all data before making any changes.
Before proceeding, test on another network, if possible. That could be a public Wi-Fi hotspot, if your computer is portable, or a cellular network if you have a mobile device that can share its Internet connection. If you find that iMessage works on the other network, the problem is in your network or at your ISP, not in your computer.
Step 1
Check the status of the service. If the service is down, wait tor it to come back up. There may be a localized outage, even if the status indicator is green.
Step 2
Sign out of iMessage and FaceTime on all your Apple devices. Log out and log back in. Try again to sign in.
Step 3
Restart your router and your broadband device, if they're separate. You may have to skip this step if you don't control those devices.
Step 4
From the menu bar, select
▹ About This Mac
Below the "OS X" legend in the window that opens, the OS version appears. Click the version line twice to display the serial number. If the number is missing or invalid according to this web form, take the machine to an Apple Store or other authorized service center to have the problem corrected.
Step 5
Take the steps suggested in this support article. If you don't understand some of the steps or can't carry them out, ask for guidance.
Step 6
From the menu bar, select
▹ System Preferences... ▹ Network
If the preference pane is locked, click the lock icon in the lower left corner and enter your password to unlock it. Then click the Advanced button and select the Proxies tab. If the box marked SOCKS Proxy is checked, uncheck it. You don’t need to change any other settings in the window. Click OK and then Apply. Test.
The result may be that you can't connect to the Internet at all. Revert the change if that happens, or if iMessage still doesn't work. Remember that you must Apply any changes you make in the preference pane before they take effect.
Step 7
Select from the menu bar
▹ System Preferences… ▹ Flash Player ▹ Storage
and click
Block all sites from storing information on this computer
Close the preference pane.
Step 8
Make sure you know the ID and password you use with iMessage. Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
Use the search box in the toolbar of the Keychain Access window to find and delete all items with "iMessage" or "com.apple.idms" in the name. Log out and log back in.
Step 9
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
If iMessage worked in the guest account, stop here and post your results.
Step 10
Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you start up, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start and run than normal, with limited graphics performance, and some things won’t work at all, including sound outputand Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. After testing, restart as usual (i.e., not in safe mode) and test again.
If iMessage worked in safe mode, but still doesn't work when you restart in "normal" mode, stop here and post your results.
Step 11
Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/com.apple.apsd.plist
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
Step 12
Reset the NVRAM.
Step 13
Reset the System Management Controller (SMC).
Step 14
Reinstall OS X.
Step 15
If none of the above steps resolves the issue, make a "Genius" appointment at an Apple Store, or contact Apple Support. When you set up a support call, select "Apple ID" as the product you need help with, not the hardware model. That way, if you're not under AppleCare, you may be able to talk your way out of being charged for the call. -
I have used iMessage on both my iPad and iPhone for successfully, using the same Apple ID. However since I upgraded to IOS 7.0 .4 on my iPhone recently, it has turned off iMessage. When I try to turn it back on again and login with my Apple ID, The message "could not sign in. Please check your network connection and try again" appears. I have tried again numerous times. I have tried switching off iMessage on my iPad as well then try and switch on them both back on my iPad works but my iPhone does not. Can anyone help
-Deactivate iMessage on your iPhone
- Reset phone by holding both Home and Sleep buttons for about 10 seconds until Apple logo appears.
- If you have wifi where you are, temporarily disable it.
- Activate iMessage.
Tell us what happens next. -
Just for the record:
I had received the error message "An error occurred while uploading one of your files. Please check your network connection and click Retry to resend your file" after all data apparently had been uploaded.
After trying everything recommended on the internet, I finally found the culprit: Glimmerblocker, an ad blocker!
(GlimmerBlocker version 1.4.16, Mac OS X 10.7.2 Lion)
Actually, the credit goes to the very patient German Apple support: they had finally asked me: "what software have you installed lately" ... a big applause to the guys there!
Best,
Gabriel.In our case, it was not third party software, but a problem with our router not accepting pings. If you are using a router be sure to set-up Enable WAN Ping Respond, in the advanced settings. I reviewed my wireless router's logs and found that it was blocking ICMP Type 3 packets from Apple's server. As a result, it would give the message, "An error occurred while uploading one of your files. Please check your network connection and click Retry to resend your file." You can find the blocked packets in your log based on the time you clicked the buy button for your iPhoto purchase (in my case about a dozen times). If your packets are blocked, then that is your problem.
I should have suspected it was the connection since the message plainly said, "...check your network connection...". However, I discounted this along with so many others based on the forums, since I could connect to the internet. If there only was a way the message could have gave a little more saying, "Enable your WAN Ping Respond now, or else!"
Good fortune on your road to Macenlightenment! -
Can't connect to Facetime or messages on iPod touch. When I try to sign in, message says to check network connection and try again. I have tried multiple times with both apps with the same result. There is nothing wrong with my internet connection as I am able to check my e-mail and all of the other apps that require wifi so I can't figure out what the problem is. Has anyone else had a similar problem?

Cannot install Firefox. When I click on the link on the Mozilla website, it goes to an "error loading page". My network connection and Internet Explorer are fuctioning normally.
== computer was recently wiped clean and am now reinstalling all previous software and applications ==
== User Agent ==
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)None of the stuff in " http://kb.mozillazine.org/Locked_or_damaged_places.sqlite " helps. I have tried and tried and I have even wipe the computer clean still didn't help. I got the same problem as he/she has got in the first posted. Can add some web pages but not all the web pages I want.. I should have never updated to 3.6.13... That's when it all started for me, from that version..... Now Version 3.6.14 is out, I was hoping the version 3.6.14 might would fix the problem wrong again....
Funny thing is i can not even Bookmark Firefox.com!!!!!...lol
So any ideas on how to fix it other than the link giving would help.
Thanks. -
When I try to sign in with my Apple ID and password, it says I can not sign in. To check my network connection and try again.
I am connected to my home wifi network. Why can't I sign in??Not sure, but iAd Producer probably has nothing to do with this.
Did you try posting in a forum that discusses iPhone, or FaceTime, or networking?
I searched and this looks like the best fit : https://discussions.apple.com/community/iphone/using_iphone
