Hello, only happens on some machines.
Ja took a look in the settings of Switch core that could be impacting it, as locking broadcast, access mode, dhcp snooping, but found nothing wrong.
The event viewer of the machines does not report any error, by disabling IPV6 message unauthenticated network disappears from the network interface, but on reboot, reappears.
I have exhausted all lines of research and can not find the cause of the problem, the machines access the folders on the network, log on to the domain, surf the internet normally, but the message does not come unauthenticated network interface.
Any tips on how I can resolve this?
Thank you!

My TP-LINK TD-W8970 router cannot connect with my iMac even though my iPhone 5, iPad 3, W7 laptop and LG smart TV can. I get the message "No configured AirPort base stations have been found". Any ideas please?

My iMac cannot connect to my TP-LINK TD-W8970 router even though all other computers can. I get the message "No configured AirPort base stations have been found" and "No PPPoE configurations were found". Any ideas please?

Open the Network pane in System Preferences. If there's a closed padlock icon in the lower left corner, click it and enter your administrator login password when prompted.
At the bottom of the service list on the left is a popup menu with a gear icon. From that menu, select
Set Service Order...
A sheet will drop down showing all listed services. Drag the one that you want to use to connect to the Internet to the top of the list. Click OK to close the sheet, then close the preference pane and confirm when prompted to save the change.

I'm trying to add my airport express to my network. The airport utility shows a message that its gathering info about my network then suddenly an unexpected error message appears. Why is that?

i'm trying to add my airport express to my network. The airport utility shows a message that its gathering info about my network then suddenly an unexpected error message appears. Why is that?

Until Bob Timmons gets back to you, first decide what you would like the Express to do. I understand you want it for AirPlay remote speakers, which you can certainly do.
I am assuming that you are not using an Apple AirPort router; if that's not the case stop here and let me know.
If your existing router is not an Apple AirPort Base Station, the Express:
can "join" an existing wireless network as a client, for the sole purpose of streaming music. If that's what you want to do, do not connect it to your router with an Ethernet cable.
can "extend" an existing wired network to serve as an additional wireless access point, which can also stream music. If that's what you want to do, connect its WAN port to an available LAN port on your router using an Ethernet cable.
Then, "hard reset" the Express according to the instructions below, and configure it. The prompts should be self-explanatory. If you run into trouble, describe which of the above two configurations you decided upon, and the point at which you're getting the "unexpected problem".
To "hard reset" an AirPort Base Station: make sure it's powered up, then gently press and hold its tiny reset button. Don't apply any more force than required to feel a tactile click. Keep it depressed for five to ten seconds, long enough for its LED to flash amber rapidly. Release the reset button. Then, the LED will glow amber steadily for about a minute. Then, it will flash amber, slowly, about once every second or two, waiting for you to configure it with AirPort Utility.

In a Roaming Network, Does the Primary Base Station have to be the only hub, or can spokes come out of an Extended Base Station?

I live in the basement of an old, brick building, in one of 5 apartments, for the building's staff. I have an older Airport Extreme and Express setup that's working for me in my unit, connect to a Comcast Ubee cable modem. The rest of the basement shares a DSL connection through a wired network that includes three routers. I've been asked to build a network that the rest of the staff can share, using my cable connection and any new hardware required. Since ethernet cable is already in place for the legacy DSL network, I'd like to re-use it with new base stations and Airport Expresses, just swapping out the old gear. But the Roaming Network setup instructions show all spokes coming out of the Primary Base Station. This does not match my situation, where my cable modem is in a different apartment from the hub of the old network.
My thought was to get two new Airport Extremes and wire one to my modem, replacing my old AE, and then place the other in my neighbor's apartment, connected by a new ethernet cable. His Extended Base Station would be where all the legacy ethernet cables terminate. I would plug them into the new, Extended Base Station on his end, and put Airport Expresses on the other ends, so each apartment (and the staff room) would have its own wired router.
Will this configuration work? If not, can anyone suggest a better way? I'm an Apple products user but some of the other guys use Windows. My understanding is that this shouldn't be a problem.

What I mean is that ethernet can be wired through switches.. (or bridged routers which are switches).
So you have
Router----Switch--Client
.      .      .   |
.      .      .Switch--Client
.      .      . |
.      .      . Switch--Client
The correct way to do this is
Router----Client
.      |
.    Client
.      |
.     Client
etc.. all clients are ethernet connected back to the router.. no switches. That means loads of ethernet.. one for every client run all the way back to a central area.
What you are proposing is to run switches (bridged routers).. so you are using each ethernet link to connect more than one computer. This is wrong from a purists point of view.
Sorry for the ASCII art work.. but I hope it makes sense.
You do not need fancy gear to make this all work.. what you do need is a main controlling router.
You cannot have two routers.. so you cannot put a switch between the cable modem and use two router. You have cable modem---ROUTER.
That single router must therefore do all the work... part of that work is to provide some way to control usage.. so everyone gets a fair share.. and keep an eye on quotas.. sadly you cannot do both with any cheap routers I know of.. what I propose you do is WNDR3800 flashed to gargoyle firmware.. this is key.. this firmware will be able to track usage and allow each user a fixed amount of your bandwidth.. upload in particular.. as even with high speed on your download you still do not have upload of the same capacity.
As far as end users are concerned they do not need fancy equipment.. they just need a wireless router. So they can get connection by ethernet or wireless.
Talk to me directly if you need more help..email is here.

I have an iPhone 5 on the Sprint Network. My iMessaging seems to work when it wants to when sending a message to others on the Sprint Network. I can send an iMessage to someone on Verizon during the same time and it works just fine?

I have iPhone 5 on Sprint. My husband is also on Sprint and my iMessage to him seems to work whenever it wants. I can iMessage to friends who have Verizon at the exact same time I am trying to iMessage my husband and the iMessages will go to and from the Verizon friends just fine, but not to my husband. With him its not even pretending to send our messages as iMessages. The send bar isn't even blue to him. To me this seems like an issue with the Sprint Network, but I wanted to see if anyone had had the same/simmilar issues and it ended up being the phone.

I can tell you that with Sprint their coverage area isn't as good as Verizon or AT&T.
Are you sending these imessage while on wifi or cellular data? Also your husband would need to be in a good coverage area.
Usually when imessage is unavailable it will send it as a text. Does your husband receive your imessage as a text?

Trying to update to iTunes 10.4.1 and I get a message "A network error occured while attempting to read from the file C:|Windows|Installer|iTunes.msi" Running WIndows 7 with all updates done. I have never had an issue with iTunes updating before. Anyo

iTunes has tried to update itself and runs into an error and tells me to manually install. When I d/l and run the iTunesSetup.exe file I always encounter the following error message...
"A network error occured while attempting to read from the file C;|Windows|Installer|iTunes.msi" and iTunes does not update to iTunes 10.4.1.
Anyone know what is creating this error message? Thanks for the help...

(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

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.

Hi Mark,
Are you trying to log in via Adobe Reader? If so, what happens when you log in via the web interface at https://cloud.acrobat.com?
(We've had reports of this error occurring in the latest version of Reader.)

Hi rebjrbaker,
I'm guessing that you're trying to log in to the service from within Reader. If that's the case, you may need to update the version of Reader you're using. Choose Help > Check for Updates. You should be using version 11.0.9 (this update was just released on Tuesday, 9/16).
Best,

About 3 hours ago I downloaded some stuff off itunes.

But this still doesnt work. Im in Australia. Anyone else finding the same thing?

Judging by other posts yes, and it looks like it's affecting a number of people/locations e.g.

After Loading Lion I now get 5 windows w/ a graphic of a Red Stop sign with an ! mark and the following text message:
"DAVE Networking
Dave kernel extensions could not be loaded! Error
71 - Too many levels of remote in path."
I have uninstalled DAVE and used Clean App to remove trace elements of program, however I still get the message and am unable to eliminate the error messages. When I click OK the message goes away briefly and then comes back up.
Any solutions would be great.

Dave,
Thanks....What I did was load the free eval version of Dave 9.0 and then used the uninstaller which must have deleted the kernel giving me the problem.
Thanks for the response.

When I try to connect to the wi-fi net work at my work place on my new iPad 3 I get a message, "unable to join the network". I have verified the password, so I know it is correct. I know the wi-fi works, because I can connect at home.

When I try to connect to the wi-fi net work at my work place on my new iPad 3 I get a message, "unable to join the network". I have verified the password, so I know it is correct. I know the wi-fi works, because I can connect at home. I have already tried the following:
turn wi-fi off and on again
did a hard restart of my iPad
reset network connections back to factory settings
verified wi-fi is working as my computer accesses internet without issue.
verified that my software is up to date.
Does anyone have more suggestions?

Couple of suggestions.
First, many companies have a gateway on their networks that block non approved devices. I work in such a place. You might check with an IT guy , and see if they have a block in place.
Second, the message you are getting means that you have not negotiated the security settings. So either the password is wrong ( case sensitive), or, in some cases, they want a network key as opposed to your normal password.
Again, if you can find one, talk to an IT guy and see if he has some suggestions.
