'An unexpected error occurred' using AirPort Utility to configure an Extreme

Hi all, I've been fighting with this problem for a while. I have a 2011 Mac Mini running OS X 10.7.5 and AirPort Ulility 6.2. I also have a new-ish AirPort Extreme A1408. They've never really seemed to work properly together. The only way to configure the device is to manually launch the AirPort Utility, go "file > configure other" and enter the password "public" to log in and manually change the settings.
If I hard-reset (which I've been doing to troubleshoot another issue) and simply choose "Other AirPort Base Stations (1)" I can see my router in the drop-down. It goes through the process of gathering information and joining the default wireless network (I'm using the unsecured default right now as a matter of fact), but then the process ends with 'An unexpected error occurred'. Even with that message displayed, the default wi-fi connection stays up (clicking cancel kills the wi-fi connection immediately).
I can always go back through the "file > configure other" process and set it up manually, but then it never appears in the AirPort Utility as a connected base station - all I see is a green light for Internet and a "No configured base stations have been found" message.
Here's what I'm seeing in the Console:
13-05-25 11:12:27.000 PM kernel: MacAuthEvent en1 Auth result for: 20:c9:d0:20:4c:10 MAC AUTH succeeded

Looks like after I open AirPort Utility, the connection to the default wireless network is established, the system goes to probe the base station, says "nope I know this guy already", then the process spits out the 'An unexpected error occurred' message, I click "cancel", and the link is dropped.
Does anyone know why my AirPort does this? Is it a network configuration setting somewhere in the Mac? I've had this thing for a while and of course decided to dive into the Apple ecosystem entirely dropping to a single Windows gaming rig, only to find that the special magic doesn't work for me

Read this please, before assuming your AirPort Extreme is broken. The links at the end will likely resolve your issues. First try to rollback your AirPort's firmware to 6.1.1, which should restore your Internet connectivity. If it does, but you'd rather have the most recent upgrade available, follow the steps given in the following links, 6.1.3 should work fine for you then.
After numerous attempts by apple IT reps to persuade me that my modem was somehow the cause of my AirPort Extreme broadcasted WiFi network suddenly losing connectivity after the 6.1.3update, I found the truth that helped me to correct my own problem, and successfully use 6.1.3 rather than the rolled back version 6.1 i had been forced to resort to.
If rolling back your Airport's firmware fixes your connectivity issue, or your dns server has been erased by the update to 6.1.3, I speculate that these links will help you out greatly.
It turned out, that this was A KNOWN ISSUE to Apple! With an actual fix Published by Apple themselves! They've just got it hidden away because they must have wanted to drive me to the brink of insanity. . Luckily for Apple I worked with an amazing rep *(Thelma) who at least acted as if she didn't think I was a crazy person. I found the fix on my own after 16 grueling, redundant and fruitless, hours of troubleshooting (time wasting) with "senior" Apple techs.
Let me tell you, 'I told you so' has never sounded so sweet. (Thelma) was ****** that no one in the company bothered to fill her in on this issue or solution and had her support send me a new AirPort just before I discovered the fix. After the discovery, she told me not to bother sending either back, and apologized for the run around that took up weeks of my life.

TS4597 AirPort base station not seen or "An unexpected error occurred" appears in AirPort Utility 6.3 - It did the above steps and cannot get airport utility to allow access to the Airport extreme in order to reconfigure please help

I tried following the article's instructions by going into System Preferences / Network and changing the configure ipv6 tab to Link local only and I STILL am getting the same error. Can someone please advise how to get this ariport extreme back online and configured

I'm in a frustrating predicament with this error, so if folks have any suggestions, that would be greatly appreciated...
A few days ago my internet stopped working as best i know out of the blue (3rd gen Airport Extreme with a couple iPhones, iPad, Apple TV's, Mac's (one with Mavericks) on it). In trying to fix it, I powered down everything and reset the router. When the router is initializing (seen through the Airport utility), the internet starts working again on the Mac in which I'm running the Airport utility. (a browser in background loads a previously unloadable webpage). I'm then left with a screen where the Airport utility is waiting for me to enter set-up info:
If I leave the Airport Utility in this state and don't hit next, my internet works fine on my Mac. If I set-up this info, however, my internet no longer works (in Airport Utility the Internet globe has a orange circle saying internet disconnected) and I get a screen saying "An unexpected error occured. Try again." I've tried toggling a number of router settings, restarting the router, but nothing seems to fix it.
I've taken the router to Apple, where they were able to create a network fine with the router. I also bought a new AE router, and tried an old AE express router, but all attempts get the same error. I've also tried using the iOS Airport utility, but that doesn't seem to help. I've tried the older version (5.6) of Airport Utility run on a non-Mavericks Mac, but that didn't help.
I had a ISP technician come out, but they basically said the plug (we don't have a modem, but just a ethernet plug in our apartment) in which you're getting the internet from us is working, and it's your router. They're diagnostics said the router is 'throwing off a bunch of errors.' That being said, they've confirmed the setting on the AE are okay (as far as they know...).
Any thoughts here? I'm not especially network-proficient, but searching around has pointed me to potential issues with mavericks, IPv6, and the latest version of the Airport Utility.
I'm desperate - please help!
Much thanks in advance.

After hard reset of time capsule, airport utility cannot setup again. "an unexpected error occurred. try again"

I've tried my iphone 4 with the same result. I've tried the utilty on my pc and same result. The airport is producing a great wireless signal and working to all devices. I really just want to get in and set the password.

When you did those resets, did you continue to hold in the reset button until the status light blinked several times? If you didn't, then you didn't do a full reset.
Here's what I do to reset an AirPort base station: I unplug it, press in the reset button, then, while continuing to hold in the reset button, I plug it in. (Yes, doing this can be easier for people with more than two hands!) I then watch the status light and wait until it flashes rapidly several times.
I have a Time Capsule that I couldn't configure at one point. To recover from that I had to unplug it for many hours. You might try unplugging your unit overnight.

Unexpected error when connecting Airport Express A1264 to Airport Utility 6.3.1

My current wireless setup is and has been the following: Phone Jack --> DSL modem ---> Airport Express via Ethernet cable
Off of that connection we've been able to wirelessly run our MacBook, Apple TV and iPhones for several years.
We recently left for vacation, so I unplugged everything (apparently a huge mistake). When we returned from vacation, the wireless connection was intermittent and kept being dropped.
If I connect the Ethernet cable directly from the modem into my MacBook the internet works fine.
I tried refreshing the Airport Express by unplugging it and cycling it through. It continued to drop.
By opening the Airport Utility, a firmware update was recommended. However, since that update the Airport Express isn't detected anymore.
I tried a hard reset and Utility finds the Airport Express under "Other Wifi Devices" but then, at the end of trying to "Join the Airport Express to the Network" I get an "Unexpected Error" message.
Airport Express Model Number: A1264
Airport Utility: 6.3.1
OS: 10.8.5
I am very frustrated and way out of my league here with understanding how this all works and what I can do to fix it. If anyone has any suggestions or expertise to offer, I would greatly appreciate it.
Thank you for your time,
Amanda

Hi AMM222,
"Unexpected Error" message with Mountain Lion and AirPort Utility 6.3.x. Hopefully this is just a matter of enabling IPv6.
AirPort base station not seen or "An unexpected error occurred" appears in AirPort Utility 6.3
http://support.apple.com/kb/TS4597
This can happen if IPv6 has been disabled. To enable IPv6 for your network interface:
Choose Apple menu () > System Preferences, and then click Network.
If a lock icon appears in the lower-left corner, click it and enter your admin name and password to unlock the pane.
Click your network service (Wi-Fi or Ethernet) in the list, and then click Advanced.
Click the TCP/IP tab.
Choose Link-local only from the Configure IPv6 pop-up menu.
Click OK.
Click Apply.
The AirPort device should now appear in AirPort Utility.
Thank you for using Apple Support Communities.

Time capsule unexpected error message using maverick and utility 6.3

I have a TC 3TB new in last year. I had it set up a to join my home wireless network, it is connected via ethernet to my iMac, and it has been working fine. I updated to mavericks last week and everything was still working fine. Until yesterday. Now my TC is not recognized. I've tried to hard reset it several times and set it up to join as before, I've tried to restore previous settings, and set up a new network, none of these have worked. I continue to get the same message, "an unexpected error occurred" and to try again.
Any suggestions?

AirPort Utility won't let me change the router mode. In fact, I can't even get to the menu shown in the picture you've posted. The button "Other Options", if this should be the way, is innactive...
You need to get in.. connect by ethernet dongle.. and make sure you have an IP from the TC..turn off wireless in the MBPr.
Then if you cannot get into the device do a factory reset.
See instructions on reset.. http://support.apple.com/kb/ht3728
In simple terms.. hold in reset and THEN power on the TC.. keep holding reset until the front led flashes rapidly .. about 10sec. no data is lost from hard disk.
Select the TC in the airport utility
Info on the unit appears. Then click on edit.
That gets you to the manual setup screen..
One last question. For option 1 (all I need is using TC just to back up stuff from my MBPr automatically via Time Machine), should I connect the TP-Link modem/router to the WAN port of TC or to one of its 3 ethernet ports?
Thanks again
In bridge it makes no difference.. but by convention we use WAN to connect to modem.. it helps to keep things clear when you troubleshoot.. but when you bridge.. WAN port is assigned to LAN.
Spell checking is always fun here.. but I refuse to follow the US convention even if normal spell check is forced to US on the website.. my posts always have lots of spelling errors. !!!

Cannot connect airport express to ipad I keep receiving the message: "an unexpected error occurred" when I try to connect my Ipad to my airport express. Does anyone have a solution?

cannot connect airport express to ipad
I keep receiving the message: "an unexpected error occurred" when I try to connect my Ipad to my airport express. Does anyone have a solution?

I could not "see" my Express via my wireless router or via the Airport Utility until I reset it to Factory Settings by unplugging it then holding in the tiny reset button while plugging it back in, waiting for the flashing yellow LED signal before letting go.
Then I set it up to DHCP - "connect to wireless network" and DOWNGRADED the firmware to 7.3.x
I would tell you the exact Firmware but I can no longer "see" the Airport express............ AGAIN or still.....
BUT at least I am listening to music streaming from my MacBook Pro... Hmmm.
I log back into the router (Linksys WRT110) and it no longer shows the Airport Express as a DHCP client AND the Airport utility can no longer "find" any Airport Devices..
So if I don't move, or there are no cosmic events, or maybe my KARMA is effecting the device or my "VIBES" are good, but I'm not sure if will continue to work.. Sure would like to use this little device from hel*.
Since I have had this Airport Express I have spent many hours trying to get it to work.
It works just long enough to fool me and then takes a dump...
Maybe this time?
5 Minute later...
Music was playing. I went into iTunes and switched from Airtunes to Computer speakers. When I tried to switch it back GUESS WHAT?
[An unknown error (-15006) occurred while trying to connect to remote speaker "Airtunes"]
Wonderful Green LED though. Totally useless piece of equipment AFAIK.

Airport TC 2TB after following all Setup instructions. Error message "an unexpected error occurred try again"

After following setup guide my Airport TC 2TB will not get past the amber flashing light. Message is "an unexpected error occurred. pllease try again."
my cable modem allows me to connect to internet
my Airport allows me to connect to the internet while it is searching and preparing my network. When I cancel out after the error message above I lose internet connectivity.
Any help would be appreciated.

Completely isolate the Mac and the TC from the network.. plug the TC lan port by ethernet to the Mac.
Factory reset the TC.
Factory reset TC Gen 5 or AE Gen 6
Unplug your AE/TC .. hold in reset and power the TC/AE back on.. without releasing the reset.. wait until status led flashes rapidly.
Make sure in the ethernet settings you have ipv6 set to link local and the dhcp set for ip. It should give you an address of 10.0.1.2
Open the airport utility, using the top menu.. File, Configure Other.
Type in the address, 10.0.1.1 .. no password is required at this stage.
Click ok and the main setup will open.
Set all the names short, no spaces and pure alphanumeric.
Set the TC to the right mode .. dhcp+nat for router or off (bridge mode) for bridge.
Set wireless to create a wireless network.
No luck then the TC is faulty and needs to be returned.

Airport Express - "An Unexpected Error Occurred"

Airport Express A1264 (802.11n compliant), trying to set it up using OS X Mavericks (10.9.3) OR Snow Leopard (10.6.8).
I do a hard reset on the Airport Express by depressing the reset button and plugging it in. The Airport Setup utility recognizes that there is an Airport Express, I am able to connect to it and try to set up a new network by entering a password, network name, etc. In BOTH system versions the AE is updated and it says it's restarting, but that is it. The WiFi network name never appears and the connection times out - I get an "unexpected error occurred" message. The AE is not recognized again unless I reset it but that doesn't fix my problem.
What I've tried:
-Have already adjusted IPV6 to no effect.
-Unable to get the AE to join my existing WiFi network.
-Have tried to set up the AE with ethernet cable connected and disconnected.
Current setup is DSL line -> WiFi router/DSL modem -> AE
-> Mac desktop
-iPhone/iPad etc. via WiFi router
Any ideas? I'm pretty sure at this point it's a dud.

Power up the Express for a few minutes, and then hold in the reset button on the device for 10-12 seconds and release. Allow a full minute for the Express to restart.
Connect an Ethernet cable from one of the LAN <--> ports on the 2Wire gateway to the WAN "O" port on the AirPort Express
Open up AirPort Utility
Click on Other WiFi Devices
Click on AirPort Express
That will bring up a window that looks similar to the illustration below
Network Name........Type in a short, simple name for the wireless network
Base Station .......Type in a device name that you want to use to identify the Express
Password.......Type in a password that will be used for both the wireless network and device password
Verify the password
Click Next
When you see the message of Setup Complete, click Done
You should be able to log on to the new network and enter the password to connect

Airport Express - when extending with a second Express I get "Unexpected error occurred" and wifi goes down

I've had one Airport Express G2 running smoothly for months and now trying to extend it with a second Express over LAN cables (ie join existing network). When doing this I get "Unexpected error occurred. Try again." error and then the working base station goes offline (wifi down).
I have tried various ways of going about this and sometimes managed to bring the second one online to try different configs. But it only stays online briefly before both devices go offline (up and down constantly).
Also tried restarted the process from scratch on both devices several times but keep landing up with the same result as soon the second device gets connected.
Any ideas?
thanks

You do not indicate whether you are trying to configure the extending AirPort with an iPhone or iPad....or....with a Mac or PC.
Can you provide a bit more information in that regard?
Assuming that you are using an iPhone / iPad for the setup, or a recent Mac......the setup utility will practically configure the extending AirPort for you automatically. All that you really need to do is name the device and the setup "wizard" takes over from there.
While the utility might initially indicate that the AirPort Express will be setup to extend the network, the real key is checking to make sure that the next setup screen indicates that the AirPort is being configured to extend using Ethernet. If you don't see extend using Ethernet, then the setup will not be correct.
Once the extending AirPort has been setup, if you then go back into AirPort Utility to check the setting for the extending AirPort, the actual setting for the AirPort will be "Create a wireless network".

Airport Express won't connect to network, blinking amber light, and "unexpected error occurred."

I have two aiport expresses - both have the problem. Both continue to have a blinking amber light, when I go through all the setup activities, after completing the factory reset multiple times, I simply get "An unexpected error occurred."
In fact after I do this, my laptop has issues connecting to the network. I have Verizon Fios, not sure if that means anything.
Haven't seen this covered in any of the troubleshooting materials; they just keep going to factory reset to solve all problems, which I've done several times with each device to the same end.
Any ideas?

Hi - You can install 5.6 on Mountain Lion but it is tricky - here are instructions from a post by guru Bob Timmons -
The workaround is to use a utility like Pacifist to manually extract the application and then manually install it in the Utilities folder - see this link:
http://www.macworld.com/article/1167965/mountain_lion_and_the_ancient_airport_ba se_station.html
Another workaround....if you have Time Machine backups.....is to back in time to locate AirPort Utility 5.6 and restore it to the desktop. Then drag it into the Utilities folder.

Are you using the IMac in your profile, or are you using the iPhone or iPad to set up the Express?
If you are using the iMac, what operating system is installed on the Mac?

External hard drive networked via AirPort Extreme gives "The operation can't be completed because an unexpected error occurred (error code -50)" roughly every two days

My lab has about 10 Mac computers. We all access a central hard drive by the way of wifi provided by AirPort. It's just a regular external hard drive (Seagate Desktop Drive) that I turned into our central storage space by plugging it into AirPort (USB). It works pretty well. We seem to be fine with viewing the file directories, opening files, saving, deleting etc., for a day or two. But then after a day or two, when when trying to modify files or move new files onto the central hard drive, we get the error message: "The operation can’t be completed because an unexpected error occurred (error code -50)"
Any suggestions as to what may be causing this problem?
All of the computers are 2011 iMacs & MacPros. The AirPort is 802.11n WiFi. The hard drive is a Seagate USB 3.0 Desktop Drive.
Thank you for your insight/suggestions.

Thanks for your reply. I agree about the communication issue. Let me explain my setup and what I am trying to do and perhaps you can answer my questions or make suggestions.
I have a MAC Mini with a Sony TV for the video monitor. The Mac Mini is hard wired to the AE (Airport Extreme). The AE has a 2 TB HD hooked up to the USB Port. I have a 17" Mac Book Pro on the WIFI Network.
I am trying to use the MAc Mini as a "Media Server" of sorts. Once I get iTunes running the way I plan I am goign to hook up my Apple TV (2nd Generation) to my television downstairs.
What I am trying to accomplish is have iTunes on all my computers look to the External HD on the AE for the files. This is why I am having my (-50 errors).
So far I have noticed that if I go and try to download from iTunes purchased videos that are not ont he computer (to the external HD) it will also occassionaly give me teh -50 error.
Is there a way to change where the files go when I download them? Say I want to download videos to the computer but not to the external HD? However I would want to still be able to move them to the External HD.
