Network settings changed

Cannot connect to the internet. I don't know what happened. Cannot find server. I re-entered the information and it is showing it is connected, but when I click on Safari it says it is not connected to the internet. My network says the settings were changed by an application. I can't get that screen to go away except by turning the computer off.????

Hello,

Think there is an open bug on this...
Instead of restarting Firefox, if you toggle work offline on and then off again it should connect

Network setting changed...no printers, no file sharing

I had a message "network settings changed by another application" and could not change settings. After reading the discussion forum, Jona's fix worked to resolve that. However, I still can not print anything and can not "connect to server" to share files from my laptop to my desktop (which had the original problem with settings changed). HELP! I have many projects left to print for Christmas and have no idea where to start to fix this problem. I know it has something to do with the origninal network settings issue.

Hi AubreyM, and a warm welcome to the forums!
Did you delete those files or just lock the Security?
Have you tried connecting by IP>
Finder>Go menu>Connect to Servers..., then enter afp://ip.of.other.mac, like...
afp://10.0.1.3
afp://192.168.1.2
On the Printer, did you try removing the existing one in Printer Setup Utility, then adding it again?
Might try these two...

"Network settings have be changed by another application" stuck in loops

I have the exact problem as others with Network System Preferences saying that the settings have been changed by another application. The message goes into a loop that can only be stopped with a Force Quit of the Preferences. I also have the Airport not connecting at start-up without choosing the Network Name from the Airport Pull down menu. I also think it may have started with the last Security upgrade and Java upgrade. I have used the airport utility to reconfig the base station. I discovered a system keychain with a password for the airport that my normal passwords would not open to show what it's password was. I have done many disk permissions and verifications. Any ideas? I would think if this is a Security update error, that Apple would be aware of it by now and post a repair. I have followed some threads on this issue but would rather wait for an Apple fix. There appears to be no way to contact Apple in customer support.

How to change Network Settings on iPhone OS 3.1.3 on my iPhone 3G?

I'm using the iPhone 3G locked with Bharti Airtel in India. Airtel, for a brief time was authorized to unlock the iPhone 3G after the completion of contract period of a year but, now it doesn't.
Airtel has three network settings but I'm unable to change the settings. I need to change it to use unlimited data plan. Is there any official way to change it? and if not, will it possible to change the settings after I unofficially unlock it? Please suggest.
P.S. I'm running the latest iPhone OS 3.1.3

The ability to change the APN settings on the iPhone depends on the carrier file. Basically the carrier has told Apple if they want the settings to be enabled or not. In the case of the iPhone in Canada all carriers do not allow for the APN settings to be changed, and it would appear that Airtel is the same.
If the iPhone is being used properly with the carrier that the iPhone is locked to there should be no reason to change the APN settings.

As far as unlocking the iPhone goes the only way it to see if your carrier will unlock it for you. According to Apple you are correct in saying that Airtel does not offer unlocking, but you can always call them to double check.
http://support.apple.com/kb/HT1937
Hacking the iPhone is not recommended, and can not be discussed here on this forum. You can search Google, but if you are running 3.1.3 hacking your iPhone to unlock it might not even be an option.

Does the iOS device connect to other networks? If yes that tend to indicate a problem with your network.
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

My Network settings are being changed by another program??

When i open up system preferences>network an alert window pops up to say "your network settings have been changed by another program"...so naturally i click the 'o.k' button to get rid of it, but it immediately pops up again.
So its impossible to make changes in my network settings because it'll keep popping up, meaning the only way to close system preferences is to force quit.
What could this other program be? could it be my ISP (virgin media) messing about with my settings?
so until i can fix my problem i cant even change any of the settings in the 'network' panel of 'system preferences'.......and you guys ideas to fix this would be appreciated!!

This recently happened to me. Go to System Prefs, Security. Click on Require Password to Unlock each secure system preference. That should do it. After you fix it, go in to security prefs again to uncheck it, or you will have to enter password each time you want to change any system prefs.

Possible in any way to change tcpackfrequency/tcpnodelay/other network settings in win 8.1?

As far as I've been able to find, pretty much everything has been locked down in windows 8+ regarding network settings (templates) in general which were earlier easily editable by either netsh or going into the registry.. unless you're running a server
version, which of course most aren't.
Why was this even done? Not like the normal user will accidently change these settings, for power users, as a gamer myself, I would like to tweak everything possible to get the lowest ping since this is one of the few things you can do on your own side that
affects it at least a decent amount, except for having a good router and whatnot. The larger part is up to being lucky with your isp.
So please make it possible to activate and edit the InternetCustom in normal setups.
If it's not possible to do this for whatever reason, please at least make a specific template for low ping desired setups as a gamer, like InternetGaming or similar.

I accidentally changed network settings and now I can't connect to internet

(I posted this on the board for OS X 10.4, but I figured my OS is irrelevant to my problem, so I thought I'd post it here for a better chance of getting help)
I accidentally changed some network settings on one of the computers on my network, and now it wont connect to the internet. All the other computers on the network work fine. I guess I need help getting things back to how they were.
I have absolutely no experience with networks, so I don't have a clue what to do. One thing I notice that might be of help is that when it's set to "Configure: Using DHCP," the section for "Router:" is blank. No address. The router address on all the other computers is 192.168.1.1. Similarly, the IP address on all the computers is some variation of 192.168.1.x, but on the problem computer it's a completely random number (as far as I can tell).
Any help would be EXTREMELY appreciated.
Thanks!

Open Network preferences on the computer, select the connection method, click on the Advanced button. Click on the TCP/IP tab and set the Configure IPv4 drop down menu to DHCP. Click on the Apply button.
BTW, you need to post your questions in the appropriate forum which would have been the appropriate Tiger forum. This is the Snow Leopard forum.

Question about changing a Snow Leopard Server network settings

We have an Xserve running Mac OS X Server 10.6.8, the primary services running on it are afp, smb, dhcp, dns, jabber and the calendar sever.
Right now we have a router connecting two networks together, 192.168.0.0/24 and 192.168.1.0/24. The Xserve has a static IP address in the 192.168.0.0/24 range.
In order to combine two phone systems into one I am required to combine the above networks, this will involve removing the router and changing the subnet mask on every device from 255.255.255.0 to 255.255.254.0, any device that is currently part of the 192.168.1.0/24 network will also need to have it's router setting changed from 192.168.1.1 to 192.168.0.1. That part should all be easy.
However, this is my first experience expanding a network past a standard class C and am wondering if there is anything I need to watch for on my Snow Leopard Sever.
Specifically I wonder about dhcp settings, right now there are two dhcp servers, the Xserve which provides dhcp for 192.168.0.0/24 and the router that provides dhcp for 192.168.1.0/24. Once the router is removed the Xserve will need to provide dhcp for the entire network.
Looking at the Xserve dhcp configuration right now I have one subnet defined providing addresses 192.168.0.5 to 192.168.0.125.
Can I simply click the + to add another subnet and add for instance a range of 192.168.1.5 to 192.168.1.125?
Will it simply give out all of the ip addresses in the first range and then start with the 2nd? Or do I need to find a single range of ip addresses large enough to meet my needs? (e.g. 192.168.1.5 to 192.168.1.225 or something).
Is there anythign else to watch for after making this type of network setting change?
Thanks in advance.

Thank you for your very detailed reply.
I understand the problems that can arise using 192.168.0.x and 192.168.1.x and if this were a new project I would definitely switch to something else, however in this case we have been using these ip ranges for years (they were in use here long before I started) and I don't want to have to redo all of my dns settings at the same time I make these other changes so I'm going to stick with the same ip's we are using at least for now. Anyone here needing vpn access has already dealt with this issue but we have very few vpn users so it has not been a major problem for us to date.
My biggest question is about increasing the size of the dhcp pool. For instance, after I change all the network settings and set up a /23 network is it possible to have a single dhcp pool that includes some ip's in the 192.168.0.x range and others in the 192.168.1.x range? I guess what I am asking is when I am in Server Admin and click on DHCP one of the tabs across the top is "Subnets". Right now there is a single "subnet" configured that provides addresses from 192.168.0.5 to 192.168.0.125.
Ideally I would like one dhcp pool that provides ip's in the range of 192.168.0.5 to 192.168.0.125 and then if all of those are used up, moves to 192.168.1.5 to 192.168.1.125. Can I do that by simply adding another "Subnet" so there are two? Or do I have to find one larger single range? (e.g. 192.168.1.5 to 192.168.1.225?) You may have already answered this indicating I have to have a single larger range but I just want to be sure.
The parts about changing subnet masks, and routers and all that I think I have a pretty good understanding of.
Your last paragraph is something I have been worried about, I do have a feeling that after making this change there will probably be unforseen issues that will need to be resolved, I'm just hoping it is not too many. For the scope of this thread I will just focus on issues that may arise with the Snow Leopard Server however.
Again, thank you for your help.
