Network preferences problem

At one point, I hooked a Mac G5 running 10.5 up to my modem to help a friend update some things and since then when I go to Network Prefs a drop down menu appears saying "Your network settings have been changed by another application". I click the "OK" button and it retracts and immediately returns. I have to force quit preferences to get out of the situation. As far as I can tell all my settings are the same and have no problem connecting to the internet. The only thing that's different is before I connected manually and now it connects automatically. Does anyone have a way to remedy this annoying situation. Under the present situation, I have no way to change any settings if I had to. I appreciate any and all help. Thanks

HT4628 My Wi-Fi connection on my iMac drops frequently. The other computers in the house do not have this problem. If I go into the Network Preferences and choose my Network it connects immediately but it does not remember the setting.

My Wi-Fi connection on my iMac drops frequently. The other computers in the house do not have this problem. If I go into the Network Preferences and choose my Network it connects immediately but it does not remember the setting and I must reselect my network frequently.

The iMac picks up a wireless signal from the back of the screen, so you would want to avoid having it close to a wall, or in a confined area where the wireless signal cannot easily reach the iMac's antenna.
We don't know how far the iMac is from your wireless router, or how many walls or other obstructions might be in the signal path that would limit the quality of signal that the iMac receives.
Nor do we know whether you might have a cordless phone near the iMac, or whether you may be using a wireless keyboard and/or mouse....all of which can interfere with the wireless signal.
Can you provide some more info on this?

My 2012 Mini OS 10.7.5 cannot see the Ethernet connection to my Actiontec GT701 WG. The Network Preferences says "cable unplugged". The WiFi connection is working fine. Please Thank You

Never mind, problem solved. When I retunred to the Network tab the message had changed to "connected, no IP address" so I got that from the WiFi tab and configured the Ethernet manually. Have a nice day @:-)#

I can't connect to the internet. I keep getting an 'error in the network preferences pane'

Hi
I am having difficulties connecting my 2102 macbook air to the internet using 10.9.1 mavericks. The problem is that when I select the networck in the preferences networks panel, the panel extends down and says
Preferences Error
There was an error in Network perference pane.
my machine keeps serching under the network menu item but it cannot connect to any network. I can connect tho this network no problem using my iphone or through my main computer which has a wired link.
I have tried an apple hardware test which showed up as having no problems.
What should I do?

Some users with various Wi-Fi problems have reported that they were given the following instructions by Apple Support, sometimes with success. After completing the procedure, you'll have to recreate all your settings in the Networkpreference pane. Make sure you know how to do that before you begin. Taking screenshots of the preference pane may be helpful.
Step 1
Back up all data.
Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/SystemConfiguration
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password. Reboot and recreate the network settings.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combinationcommand-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
Step 2
Reset the System Management Controller.
Step 3
Reset the PRAM.

Unable to open network preferences

I'm unable to open the network preferences window inside system preferences. When I try, it just keeps saying "loading network" and nothing happens. I found a couple other discussions about this and trashing a .plist file, but it's not very clear how to solve the problem. Does anyone have any experience with this?
Thanks in advance,
Chris

Open /Library/Preferences/SystemConfiguration/, move everything but Boot and PowerManagement plist files to the Desktop (in a folder), restart, and see if you can reliably reset everything.

Cannot open network preferences, security, or downloads; blue screen appears

I have recently discovered that I cannot open my network preferences, security, or downloads folder. I do not know what else I am unable to open. For these three, I click upon them and instantly a blue screen appears, quickly followed by my desktop with all programs (except Finder) shut down, as if I was just logging on. The MacBook Pro is not yet a year old. I have recently downloaded the Amazon Cloud and was wondering if this could be causing the spastic behavior. My boyfriend seems to think that it is a corrupt file. Does anyone have any ideas on how to fix this problem? Thank you.

I receive a not connected to the internet message several times daily on my iMac connected via airport to a time capsule which accesses the internet via cable modem.. When I input my password to enter network preferences, the connection re-establishes.

I receive a "not connected to the internet message" several times daily on my iMac connected via airport to a time capsule which accesses the internet via a cable modem. Software/firmware is up to date on the iMac (OSX 10.6.8) and Tme Capsule(7.5.2). Browser is Safari 5.1.
When I input my password at the prompt to enter network preferences, all the lights go green (ie... ethernet, ISP etc.) and the connection re-establishes immediately and states "the connection appears to be working normally".
It more of a nuisance than anything and seems to have started ocurring over the past couple of months. I also have a windows XP box also connected to the same cable modem that I never have internet connectivity issues with. I've verified all the physical aspects of the connections and can't see any evidence of any actual drops in the modem logs. I suspect it is just an intermittent communication loss between the Imac and the Time Capsule, but I am not very familiar with Mac equipment yet.
Just wondering if anyone has experienced a similar problem and what you did (if anything) to resolve it?
Thanks.

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.

How to restart base station from airport utility? I used to be able to do it remotely
I currently use a Mac Pro 10.8.4 and have a time machine for wireless 6.3 (630.34). Sometimes I cannot connect to the internet and use network preferences to diagnose the issue. This results in being told to restart the wireless. The airport utility includes the drop down option of restarting but is not clickable so I can't choose it.
With my prior macbook and same time capsule, etc if i had problems connecting to the internet I would run network diagnostics to help out. This included clicking on the airport utility ---> base station --> restart. This worked most of the time.
Bottom line, is there something I am missing in not being able to restart the wi-fi remotely? ]
Thanks in advance

You are likely forgetting a step.
Open AirPort Utility
Click on the Time Capsule icon
Click Edit in the small window that appears
Now click the Base Station menu.....top of the screen....not the Base Station "tab" in the center of the screen
Click Restart

MacBook (ML) won't connect to Wi-Fi, no network preferences, no Spotlight

Hi,
First of all, thank you for taking the time to read and help ! :-)
I have not been able to find any kind of solution to my problem, because I did not find anyone with all these problems at once.
Here's what's wrong: out of the blue, my mid-2009 Macbook (white unibody) won't recognize any network (WiFi or Ethernet), refuses to load the Network preferences pane, and won't allow Spotlight to work (is "loading" everything on the right side of the upper bar, including the clock...). The Energy Saver Preferences pane seems to be out too.
I just upgraded my Macbook RAM, and subsequently upgraded from Snow Leopard to Mountain Lion, but it had worked fine for a week (granted, a week of not much use).
Booting seems to take more time too, so I'm considering a system repair or whatever the name is, but I'd like to understand the issue, and how to avoid it in the future !
Moreover, I'm not sure on how to repair my OS without any network .......
Thank you for the help ! ;-)

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot 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. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Thunderbolt ethernet not showing up in network preferences

this is happening with both my thunderbolt display and thunderbolt<->ethernet adaptor....
the ether net in the t-bolt display WAS working.... but was having probs with the ethernet adaptor while on the road, so I tried deleting the thunderbolt ethernet entry from the Network Preferences panel. Well, now when I hook up my thunderbolt Display, the option doesn't re-appear! So now I'm thinking there's something in the system that's keeping that from re-appearing in the network preference panel, and it could be the reason for both items not working.
The controller is recognized at a low level by the system - in system report I get:
Apple 57761-B0:
Name:          ethernet
Type:          Ethernet Controller

So it's a problem with the Network Preferences panel getting loaded, somehow.   I tried re-creating the kext cache, that didn't help.
Digging around a little in the system, I see this:
cd /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/
$ ls
AppleBCM5701Ethernet.kext          AppleYukon2.kext
AppleIntel8254XEthernet.kext          IOEthernetAVBController.kext
AppleUSBEthernet.kext                    Intel82574L.kext
AppleUSBGigEthernet.kext          nvenet.kext
But I'm out of ideas how to get the thunderbolt ethernet option back into the Network Preference panel. help?!

I also tried disconnecting the display and adding it back and rebooting - nothing worked.
But here's a bizarre twist: I show "Bluetooth PAN" connected and active, and it's coming from the Thunderbolt display! I can get online. Then I disconnect the network cable from the display, and test again - no network. So somehow, the driver for Bluetooth PAN is totally confused with the display Ethernet. In fact, the Bluetooth PAN shows connected, and "No PAN devices found". So I'm connected to a phantom device.
Maybe deleting the PAN and display, adding back the display, will get it to recognize it properly.
The short of it is I have Ethernet connected now through the display, but using the Bluetooth PAN device driver.

My wi-fi worked fine on Airport Express two days ago. Now the light is green, but I can't get the Internet on my satellite connection. I've checked Network Preferences, Aiport Express menu, and the satellite tech support. The Ethernet connection works.

My wi-fi connection from my iPad via the Airport Express Base Station on my home computer worked just fine until yesterday morning. I have a Macintosh G5 with a satellite connection. I could not get an Internet connection. After using the Network Preferences and Aiport Express applications several times, then unplugging and replugging in the computer, satellite modem and Airport Express module, checking the satellite dish for any obstructions, and so on, the computer still wouldn't connect to the Internet. (The green light was on in the Airport Express module.) I called the satellite company technical support division last night. The tech couldn't find any problem with the satellite connection. When I plugged the satellite modem cord directly into the Ethernet outlet on my computer, I could pick up the Internet.
Today, the Airport Express module still has a green light but still doesn't connect to the Internet. The only thing I can think of is that lights went out for about 15 minutes yesterday morning. All of my electronics, except the Aiport Express Base Station, are on surge protectors. Why would the Airport Express module still have a green light if it was damaged by the electrical outage?
I bought the module in 2009. I have never had problems with Apple equipment before this. Is this base station fixable?
I would appreciate your suggestions.

Hello everyone. I too have experienced the same problem Mary described starting on the same day she mentioned January 12. I have a G5 iMac, a G5 mini-mac, and a G4 laptop. They were all working fine but all have mostly the same problem now in that the G4 does not connect at all and the G5s connect once in a while after restarts but do not maintain the connection. In my case there was no power interruption. In fact, the G4 laptop was not even connected to the home power connection. My iPad2 and iPhone 4s wireless work fine and a wireless PC and Android tablet work fine as well. The G5 and G4 work fine on an ethernet connection. ISP tech support (AT&T u-Verse) was very generous with their time in trying to solve my problem although it was established early on that their connection and equipment was working fine and that the problem was with my computers. They walked me through a manual reset of all the particulars on IP addresses etc. so the problem was not related to that either. In the end ISP tech support concluded that the problem must lie with the Airport driver. For some reason it changes the IP addresses to an incorrect address so it cannot connect. Indeed when I tried the diagnostics on the G4 I got a window Pop-up that said an application had reset my settings. (In retrospect I seem to recall that I may have gotten that same message early on with the G5s but at that time I did not think much about it and went about trying to reset the settings but that process never concluded well) I think that the problem may be that there must have been an update of the Airport software that was not backward compatible with the G5 and older Macs. I mention all this for two reasons. First, perhaps someone out there who knows better than I do how to bring this to Apple's attention and perhaps they will address this. Second, I would be curious to know whether there is anyway one can return a configuration on Macs to some earlier time period (as you can on PCs) when everything worked and then leave it that way foregoing any subseqent upgrades or any subsequent apps?

"Back to my Mac isn't working properly because your DNS server isn't responding. Contact your ISP for an alternate DNS server address, and enter it in Network Preferences".

Hi, i am trying to setup back to my mac at home but I get the error "Back to my Mac isn't working properly because your DNS server isn't responding. Contact your ISP for an alternate DNS server address, and enter it in Network Preferences".
There is no documentation on how to solve this anywhere.
I have an Arris router set to bridged mode which is connected to a 5th generation airport extreme. I have tried using the google dns servers instead of the one assigned by the cable company in the AE but I still get the same error.
Any help would be much appreciated
Kenneth

New to BTMM, I got stung today with the silly DNS problem message. Solution:
1) Flush DNS cache with:
dscacheutil -flushcache;sudo killall -HUP mDNSResponder
2)System preferences > iCloud > untick BTMM then tick it again. The warning should have disappeared.
Edit #1
Apologies for the noise. The warning has come back
Edit #2
Just found out that BTMM is not compatible with double NAT. That's not helpful.

Built in ethernet not showing in network preferences

A friend has been experiencing random dropouts via airport, as a workaround she has been using a direct cable to the adsl router from time to time. Now all of a sudden she cannot see the ethernet anymore.
In network preferences ethernet is not displayed in the network status, regardless of whether a cable is inserted or not.
About this mac lists an ethernet adaptor and ethernet is enabled in the network port configurations in the preferences.
Dis/enabling the ethernet in network port configurations has no effect neither does repair disk permissions.
The machine is less than a year old, fully updated and still under warranty, anything else she can try?

did you fixed the problem?
i am having something like you where the ethernet worked for a while and then it was greyed out... and i went as far as formating my computer and reinstalling os x... but now the computer thinnks i don't have a ethernet card...

Getting a "Your network preferences prevent us from communicating with the server" error in dw 5.5

Hello, lately i noticed dw 5.5 can't seem to use browserlab, it says "Your network preferences prevent us from communicating with the server"
I can connect to BC and other ftp servers no problem, I've also turned off my firewall to be sure and it still won;t connect.
The only info I found on this error is a tip on how to turn off browserlab, which in turn gets this error, Not sure why you would wnat to shut the feature off, but no tip to turn it on. The tip on editing the registry doesn;t help because itsyays to change the registry key to 0 and all communication of adobe products will be turned off, however the key does exist and is set to 1, so I can;t even try that tip in reverse to enable, itshould be communication already.
Any help would be appreciated, I am just competinga site and was about to check it in all the browsers, an incredibly useful and time saving feature, but I can't now.
Rich

Phil, the only screenshot I've seen from you is the error message (and I can't seem to view the others you just posted), so apologies if I told you something you'd already tried. We still think there should be a solution to this, it's just that debugging issues this way can be a little difficult, so please bear with us.
At this point our best guess is that there is a registry setting that got changed that is causing the issue for both of you. We have been able to repro the issue on Windows XP by setting the following 32-bit registry entry to 0. The issue was fixed by changing it back to 1. We've also tested on Windows 7 and verified the same thing with the 64-bit registry entry. Apologies if I'm suggesting something that any of you has already tried, but no details were provided about which registry entry you checked or what article you were looking at.
From the CSLive team:
"To my knowledge the only way to get that error message is to disable CSLive in the registry. The Customer does not mention the exact article or reg value that he is looking at in his post but it should be:
For 32-bit systems: HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\AdobeOnlineDefault.
For 64-bit systems: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Adobe\AdobeOnlineDefault
http://kb2.adobe.com/cps/846/cpsid_84665.html
He should delete the AdobeOnlineDefault entry in the registry and try again. (he may need to stop and restart CS55Services Manager or reboot machine)."
Let us know if this fixes the issue for you or not. As with any change to the registry we recommend you make a backup first and proceed carefully.
Thanks,
Mark

Built-In Ethernet Port Doesn't Show Up In The Network Preference Pane

My ethernet port no longer shows up in the Network preferences pane under Network Status. The status Airport and the Internal Modem are still displayed though. Plugging in an ethernet cable causes my machine to crash; sometimes I get a message that I need to hold down the power button to reboot, and other times command line-like text is displayed on top of whatever was on screen.
The only change I've made to my system since last using a wired connection was installing Security Update 2006-001 on March 1st and OS X Update 10.4.5 on February 14th. After running the 10.4.5 updater, my machine initially refused to reboot. On the first attempt, it played the start up chime, but the screen remained black. The second time, the Apple logo appeared, but the spinning pinwheel never did. The third attempt was successful and my system appeared to be functioning normally.
How do I get my ethernet port to work again?

Does "Built-in Ethernet" show up as a choice in the 'Show:" popup? If so, is it configured as you would expect? For instance, if "TCP/IP" is set to use DHCP, do you have an IP address, subnet mask, etc.? There is an "off" setting for TCP/IP; make sure that hasn't been selected somehow.
There is also an "Assist Me" button that will let you launch the diagnostics app. Does this also crash the Mac? If not, what are the results of its tests?
Also, you may want to do a permissions repair with Disk Utility if you haven't done this since applying the updates.
If you still get crashes, there may be a conflict with a log-in item, particularly if you have any third party ones. (Check that in the "Accounts" pref.) One way to diagnose things like that is by creating a new test account & logging into it. If the problems go away, you can assume a user cache, .plist, or login item is the problem.
If none of this turns up anything, you may need to reinstall the OS. Short of that, you can try downloading the 10.4.5 combo update & running it. It replaces more components than the "delta" update so it just might do the trick. Besides, if you end up having to reinstall the OS, having the combo version handy will save you the time of downloading & installing any incremental updates to get back to 10.4.5.
As always, backup all important files before applying any updates.
Good luck!
