OS X :: Unable To Connect To Internet / Settings Changed By Another Application
Mar 15, 2010
I am connected to the internet via a belkin N+ router..... this is in turn connected to an adsl modem...I am having no problems with the signal to the router but at least four times a day my internet disappears....
When I run Network Diagnostics hey presto, your internet is working fine....The only things I have changed recently was that as I am running osx 10.4.11 I was having that issue where you couldn't access Network in sys pref, it kept saying "your settings have been changed by another application", I found a solution on here whereby you delete the plist prefs and rebuild them... That worked a charm but now I'm wondering is this connected in some way....
or...
I got software from the makers of the belkin N+ wireless usb dongle chip that came with my router (belkin don't provide osx support but said that I could get a utility from the chip makers) I installed this but it never worked so uninstalled it, and ran disk utility and safe boot and pram and fsck (everything I could think of)
I only have one location in network, and airport is the only active network port
any ideas...????
System:
imac G5 20" | osx 10.4.11 | belkin N+ router | airport extreme card

My neighbor has an IMac with OS 10.4.11 installed. When I open System Preferences and select the Network icon, the Network window comes up but it is overlayed with a message that states: "Your network settings have been changed by another application." When I click OK, this same overlaid window comes back.
The only way I can get out of System Preferences at this point is to do a Force Quit. In other words, because this overlaid window appears, I am unable to access the Network window to look at TCP/IP settings, make changes, etc.
Next I went into System/Library/Preference Panes/Network.prefPane(more info) to look at the application that appeared in the "Open with" field. It stated "System Preference." I replaced this with a new "System Preferences from the Applications Folder, but the same thing happened - even after I rebooted the computer.
Please let me know how to solve this problem so I can access the Network System Preferences properly.
Thank you.

I'm getting a message every time I open Network in System Preferences saying "Your network settings have been changed by another application". I click OK, and the box goes away and immediately comes back. It means I cannot use the Network part of System Preferences at all, because this message is caught in some kind of loop, and won't go away.

My girlfriend changed the user's name and the problems started (iMac wouldn't remeber system settings and denied access to some files and catalogs). When I wanted to fix the problem I probably made a mistake and changed the access settings of some files (finally even hard disk's settings). After this action my iMac doesn't start (the screen is white with the apple logo and nothing happens). Is there anybody who knows what to do now?

I'm running OSX 10.5.8 on a Macbook Pro, and today I've been unable to connect to the internet via ethernet or wi-fi, unless I'm in safe mode. Then everything seems to work as it should, which makes me believe that this is a software issue rather than a hardware problem. I've tried making a new account with administrator priveleges, but that doesn't solve my issue. Does anyone have any advice on how I can connect to the internet under my normal user account, rather than in safe mode? I should note that I won't be able to get my hands on my repair CD or perform a clean install of OSX because that stuff is at home, and I'm in college. Also, I'm at a university and don't have a router. I just use the campus-wide wi-fi. Finally, my roommate has no problem accessing the internet in our room via ethernet or wi-fi, but I do. Thanks for the help everyone.

when I open my Network in System Preferences, "Network settings have been changed by another application" pops up and every time I click Ok, it pops up again, not letting me be able to access any other option in the Network window. The wireless icon has disappeared from my top bar and the only way I have managed to get online is via my ethernet cable. I have had nothing but problems since I started using my O2 Wireless Broadband dongle and I've noticed that behind the "Network settings have been changed by another application" notification, I can seen the Dongle has appeared as a new network connection option... but was never there before today (have been using the dongle for two months now)

My boyfriend is using a 2 week old MacBook Pro on OS X Lion (10.7.3).
He came in from work and was using it on the internet with no problems, it had spent the whole day downloading a patch for WOW from Blizzard... However, suddenly, he asked Safari to open a new page and BAM! Safari cannot connect to the server. It cannot connect to any website, iTunes store cannot connect, Blizzard updater keeps complaining that it has lost the internet connection, so it's not just a Safari issue.
We've checked the network connections and everything is fine, Network Diagnostics says there is nothing wrong. We've reset Safari, rebooted the Mac, rebooted the AirPort, deleted the network connection and added it again... no joy. Also we've plugged the Mac into an ethernet cable and it is still the same, so not an AirPort issue either. I'm using a MacBook on the same network, so it's not the network.
I think it's something wrong in his network settings
Console says:
<APS Courier: 0x7ff0a3200560>: Stream error occurred for <APSTCPStream: 0x7ff0a3021e20>: The operation couldn't be completed. Network is unreachable.

My MacBook Pro will not open any app or program that requires Internet, even though I am connected to the web. I recently installed Norton AntiVirus and think it may have changed a setting that I couldn't find. I uninstalled Norton and it didn't help. Every time I open Safari, iTunes or any other program that tries to connect to the Internet, it crashes. Strangely enough, Skype still works, but nothing else. I have OSx 10.6.8. I have tried erasing plists, and all the standard troubleshooting, ie resetting modem, restarting computer, reloading Safari from disk.

My Dad is currently unable to connect to the Internet with his Mac.
He's using Mac OS X Version 10.4.11. It connected fine this morning but he's been unable to connect this afternoon or this evening. A message keeps popping up saying: "Could not find a PPPoE server". I've tried running through the wizard for setting up the connection but it doesn't seem to work.
I've been using my PC online all day with no problems.

i recently bought an Airport Express, and i finally took it out of its box after i purchased my new stereo. I connected the audio cable to the stereo and the airport unit and plugged it into an outlet. I opened up airport utility on my mac, AX appeared and i configured it to "join a wireless network". After completing the remaining steps, i updated it.. and waited for it to restart. Now here's my problem. It comes up with an error telling me it couldn't find the device after restarting. I have Verizon FiOS as my provider.. and I know that airport express has a history of trouble with the Actiontec router. Is there anything i can do with my current equipment to get this thing to work? I do not need to extend the network.. only join to use airtunes and print wirelessly... Also, my Actiontec router and FiOS connection are through my crappy dell pc downstairs, while i am using my 24" iMac upstairs in my bedroom trying to connect this. Should i change my router's settings?

Anyway, so I bought a 15" 2.66GHz MBP beginning of December and up until a day or 2 ago I've been experiencing problems when I try connecting to the internet.
There are 2 other computers in the house (Windows based, don't know if that's go anything to do with it) and they both connect just fine.
So is there anything wrong with the MBP that I can fix?
(I've tried rebooting the MBP, the router, the modem, everything...)

Anyways, i used to have a Linksys wrt54g router. It was hooked up and had an SSID of linksys. Later replaced it with i think the wrt110n or whatever the 110 draft N model number is. This router was set up and the wrt54g taken down (no longer plugged in at all). The wrt110n has an SSID of hawkes, and everything works fine but after browsing for an hour or so I will loose internet connection.
When I click the airport icon in the status bar it tells me that I am connected to a network called "linksys". I have to then click to reconnect to hawkes which is the network that I should be on.
Now I'm not sure if there is someone else broadcasting an unencrypted wireless network with the SSID linksys and my mac is just trying to connect to it at times or if it is getting confused and trying to connect to an old network?
I'm wondering if anyone has had similar problems or if anyone knows how I could tell the airport utility to "forget" about old networks with the name linksys so it will stop trying to connect to them?

I have a MBP that will not connect to the internet. The airport shows an ip, but shows failed for internet and server. I have another laptop, desktop, ipad 2&3, iphone and 3 ipods connected to wifi and work flawlessly. I called the ISP and spoke with them for about 2 hours and they say all settings are right, and they can even see the MBP on their end. Wanted to add, i cannot connect with ethernet either, wired directly to modem by bypassing router.

This is a weird one. For some strange reason, iTunes is unable to connect to the internet on both my Vista PC (I know, I know) AND my Mac AND MY iPod Touch! All my other internet-enabled applications on all my machines (PC, Mac) can connect just fine.
This is too weird. I'm wondering if my school is blocking iTunes, but seriously, that's the LAST thing they should be doing. iTunes is, you know, legit and legal.

I was happy to get my mac pro yesterday, but upon setting it up, I couldn't get it to connect to my network. When I clicked I the airport logo and the top right, it said airport was on and I was connected to the network. However, when I opened up Safari I got nothing...just a screen that said something like "you are not connected to the internet." The last time I had a macbook, I turned it on and bam, I was connected to the internet right out of the box.
After trying to fix it for 30 minutes, I decided to reset my modem/router. After doing this, the macbook connected to the internet for a few hours and I went to bed. Now I come home today and it works for about 30 minutes and then stops working. Keep in mind, my PC is working flawlessly so I know my network is up and running. After about 30 minutes, it connects again...and then stops working again. Very frustrating. As I type this message, it still wont connect to the internet even though the computer says I'm connected to the network.
Another thing that makes me think there is a hardware problem is that the macbook wont connect to my wireless printer. I've installed the software 2x and right after going through the install procedure, it will print for about one minute and then it does nothing - I get a message that says something like "your printer is not on or not connected to the network." So then I went through the steps of connecting it again and again. Every time it would ask for the password to the network so I put it in and it says I'm connected....but nothing will print. After the 3rd time, I was finally able to make it to spit something out wirelessly from my macbook...but 5 minutes later it's back to saying my printer is not on or connected to the network. This is weird because initially it works and then it stops. During this whole procedure, my PC recognizes it just fine and prints within 5 seconds. For some reason the mac just wont do it.
I thought macs were supposed to just work, but this laptop has been more frustrating than any PC I've owned. Here I am with a new macbook that can't connect to the internet OR my printer. Granted, I know very little about computers so maybe I'm overlooking something simple.
If it's a hardware problem, do you think Apple will refund my money?

Internet runs just fine on Mac OS but when I restart XP through bootcamp it won't connect to the internet. ??? Didn't have any problems installing XP and the drivers from the Max OS disk either.
I've searched this everywhere online and cant find a clear answer on how to fix. Very annoying.
New 27" imac with all the updates.
Anybody else have this problem or know how to fix?

My girlfriend's MacBook (OSX 10.4) recently decided to not access the internet. I have a Linksys wireless router with 2 PC's connected (via ethernet). She usually connects to the router using her built-in AirPort. But, a couple days ago, she was surfing the internet and clicked on a page, and she got the whole "You are not connected to the internet" window. Usually this is no big deal, just a quick power cycle for the router and we're back on track. This time is different. Not only does she still see the router (192.168.1.1), and can access it, but even when she's hardwired via ethernet cable the Macbook can't access the internet.
I love tech'ing things out, and am a real geek for troubleshooting. But, I can't figure this out for the life of me. My other PC's can connect wirelessly, and surf the internet with ease. But, her Macbook seems as if it just doesn't want to access the internet.

I have an AirPort Extreme for almost a year now. I have never had any problems till today. Suddenly all devices in my home were not able to connect to the internet except my MacBook. I tried resetting and even restoring the AirPort Extreme but nothing has worked. The only thing recently that has happened was that I updated to OS X Yosemite Beta but that was days ago.

I currently use a Powerbook, and I access the internet though our AirPort Extreme router. Recently, for some reason, although I am on the right network, and signal strength is full - I am unable to connect to the internet! I've called my provider, and everything is fine on their end according to their systems. I've tried power cycling, and checking my settings, and everything SEEMS to be ok.

So to preface my problem let me just say that ive got my own macbook which works on the same wireless network with no faults at all, so i assume its not an error with the networking hardware. For xmas i bought my parents a macbook, recently (not sure how recently as theyve only just told me its happening) they can be browsing the web then all of a sudden the internet takes ages to load, it stalls on 'trying to connect' for a long time (40+ for each web page).
Ive tried using firefox and the same thing happens so it looks like its not safari specific, during this time i cannot ping google.com through a terminal either or if i can the response time is unbelievably slow. Now, ive tried disabling ipv6, ive set the dns servers to opendns and none of this has fixed it. if i click on the airport utility and turn it off and the back on it fixes the problem for a short period of time before it happens again.

I followed the guide over in the MBA Forum to forward the right ports in order to access my USB hard disk over the internet. I can access it on LAN just fine, and it all goes swimmingly until I'm asked to enter the "Private IP Address" of the device. The guide states to enter an IP address in the fashion of "192.168....", but as you might be able to tell in the picture, the first three octets of my address field are greyed out and unchangeable, and only let me enter an address in the form of "10.0....". Following the guide to the end is futile, and device connection doesn't work as advertised. Am I missing something? Is my problem clearly with entering the wrong IP, or what.

Everytime I open up my lap from its sleep mode and try to connect to a website it says, Unable to connect to the Internet. My network connection shows an active connection to the access point. I know the problem is the DNS. When the system is in the state of saying it can't connect to the internet I can both ping my local router, and through an IP for yahoo.com into the browser and have it resovlve.
Once I start my system and let it wait for 30 to 60 seconds it will finally work. For some reason the DNS is waiting for a while to kick on.
