Airports disappeared from airport utility

While trying to add a 2nd airport express (new type, old type added already) to to my airport extreme based wifi network (to extend it) all 3 have disappeared from the airport utility. The wifi network has of course gone to. Stuck now, tried soft reset of base station. Where to start anew?

Called Apple for support (as the new airport is under guarantee). 1 hr 40 mins later all sorted. Need a supervisor to talk me through it though. Neil - what a star!!
Need hard rests, downloading the older Airport Utility, & ano all 3 are up & running well. Very satisfied

My Western Digital external hard drive suddenly stopped showing up on my Macbook Pro and disappeared from Disk Utility. It works on a PC.

My Western Digital external hard drive suddenly stopped showing up on my macbook pro and it disappeared from disk utility. I have tried making invisible files visible but nothing has worked and my hard drive shows up on a PC but not my Mac anymore.

What is the manufacturer of the external and how old is it? Does it have its own AC power supply or is it USB bus powered?

Printers disappeared from printer Utility

Not only have my printers disappeared from the printer utility window I also get the error message "server-error-service-unavailable I have tried the fixes on the OS X support page such as: Repairing permissions on the startup drive; verifying the /tmp file thru terminal but I still can't see my printers and still get the error message. Any help would be appreciated.

This just happened to me as well. G5 dual, 10.3.9. Earlier in the day I ran software update which applied a security update to the OS and some other updates (Quicktime, Garage Band, etc.). I repaired permissions before and after. For a while I could print as normal over the network (printers not directly connected to this Mac). Later in the day I suddenly got "no printers selected" and when I went to add/delete in the Printer Setup Utility, I got the "server-error-service-unavailable" message and the utility hung. I've shut the machine down completely, but the problem persists on re-start.
Are there perhaps corrupted prefs to trash? I don't want to just go trashing stuff blindly.
Or does it indicate a server problem, not my machine? Doubt it because others can print successfully.

DVD drive (?) won't disappear from disk utility

i was desperately hunting for a cd last night, and was going through various old cd is the vain hope i'd find a neglected blank one. I found what i assumed was a rewritable disc, which is something i haven't really been into, but seemed to be my saviour. i don't have toast so i went into disk utility to erase it. Except it wouldn't let me although i eventually managed to eject it
(the ejecting of disks had been behaving weirdly beforehand. Everything seems to be working ok except there is an icon in disk utility that i can't eject or unmount
Name : OPTIARC DVD RW AD-7170A
Type : Optical Device
is this the dvd drive? the now ejected disc? why can't i unmount it? It's there even after i restart my mac, many thanks

This is perfectly normal, it is your optical drive you can not unmount or eject it.
The thing with you ejecting of disk try:

Where did my AEBS go??? AEBS disappears from AirPort Utility

I have set up my new AirPort Base Station using the Airport Utility but once it is setup it disappears from the utility. I am able to use the AEBS as an ethernet router for my mini HOWEVER my secondary MacBook is only able to "find" the wireless signal periodically. It is not a distance problem since the two computers and the routers are in the same small bedroom!
Any suggestions to improve performance? Reliability? I am beginning to think that I was better off with my not so fast Airport Extreme. . .

Thanks for the quick response! I will not discount the idea that I made a mistake in the setup but I have not duplicated any of the names or passwords in the setup.
I also thought that maybe there could have been that type of issue so I reset the AEBS and used the Airport Utility to set up the router again (it seems like whenever I setup a router at home it takes at least two tries before I get all the steps right. . . so it was not a big deal).
After completing Airport Utility on my mini everything looked great, then without any action on my part the AEBS DISAPPEARED from Airport Utility!!! It makes sense to me that if the utility cannot see the AEBS then the MacBook is going to have problems too. . .
Any other plans of action? My partner, the MacBook user, is voting for taking the **** thing back even though I am really liking the much faster ethernet connection. . .

Gspeed ES Pro RAID keeps disappearing from Mac, have to re-initialize!

UPDATED VERSION:
MAC PRO KEEPS LOSING CONNECTION TO RAID DRIVE.
After 9 months of organizing a documentary film edit on an external RAID drive (12TB, Raid 0. Yes, I have 2 layers of backup), I purchased the PNY Nvidia Quadro 4000 video card for the primary edit. Soon after, I began having boot up issues. The screen would freeze at various points during the startup process, requiring manual power-downs.
Over the past two months, my computer has lost communication with the RAID 3 times, forcing me to rebuild it from my backup drives (10TB). One tech at Diskwarrior said my computer lost the partition, and that the 1s and 0s had been largely replaced with gibberish.
The Raid becomes unrecognized by my computer in one of two ways:
1- After two days of copying data back over to the raid (rebuilding it), I get an error code -36, saying a file cannot be read or written, then the Raid partition disappears from disk utility and the next time I start up the computer says it doesn’t recognize my drive. The ATTO configuration tool (the card that attaches my raid to the computer) sees the drive, but my computer does not. I have to re-initialize it and start over again.
2- The Raid will go from being recognized to not being recognized when I reboot one day. Again, I have to re-initialize and rebuild.
I removed the PNY Graphics card and put in the stock ATI Radeon HD 5770 it came with. On day 2 of rebuilding the RAID, I got the error -36 and the Raid disappeared from disk utility again. When I opened the raid folder, which seconds before had 10 TB of data on it, it read as zero items. So the PNY Nvidia card was NOT the problem.
Apple has worked on the computer 3 times, running extensive hardware tests, but the same problem persists. At one point they said my blackmagic card was the problem, and more recently they said I probably have bad ram. I tried separate ram (the old 6GB my computer came with), and my computer seemed to begin booting up okay, but one day later I had the -36 error, the RAID couldn’t be recognized again and I lost the data during another rebuild. Apple even replaced the Ram Tray, but the same problem persists.
G technology says my RAID’s hardware is fine, and ATTO, who makes the Raid card, says it looks fine to them too. This does not mean they are 100% not the problem though.
Yesterday as I was attempting to rebuild the RAID again, I saw the -36 error come up, and files stopped copying. I immediately made a screenshot and noted the time.
Today I spoke with a really cool tech at Apple named Ron who helped me investigate the Kernel log, and this is what it said (the RAID is called FadingWest):
Dec 6 17:05:36 Jesses-Mac-Pro kernel[0]: hfs_swap_BTNode: invalid forward link (0xbb739311 >= 0x0000df00)
Dec 6 17:05:36 Jesses-Mac-Pro kernel[0]: hfs: node=2717 fileID=4 volume=FadingWest device=/dev/disk3s2
Dec 6 17:05:36 Jesses-Mac-Pro kernel[0]: hfs: Runtime corruption detected on FadingWest, fsck will be forced on next mount.
Ron believes my problem is with the RAID card. He thinks it’s dropping the connection. So I’ve got an RMA going with ATTO for a new one.
Here are the final things I can troubleshoot at this point:
New RAID card (ATTO)
New RAID drive (G-Technology)
Motherboard / PCI lanes (Apple).
NEW COMPUTER (Apple)
Any ideas are appreciated. Here are the items in question:
Mac Pro mid 2010 2x2.66 Ghz 6 core Intel Xeon OS X Lion 10.7.5
G speed ES Pro (G Technology) – 12TB @ RAID 0
ATTO R680 RAID card

I found this on another help site, I think it's the trick:
there are 2 halves to the Dock. With a bar in the middle.
on the left side, there are 2 sections. the furthest left are the icons that will stay in the dock, then on the right side of the left half of the dock, are the temporary icons, the ones that just stay there till the program is done.
You can freely move a temporary icon to the left and it will be come a permanent icon.
I am reminded of the wizard of OZ here... you could always get to firefox... you just had to click your mouse (and drag an icon)..

Had a Airport Express connected to my stereo and it was working. I brought an Airport Extreme and suddenly it took over and Airport Express stopped working and disappeared from Airport Utility. What I am supposed to do? ar2ro

I have an Airport Express connected to my stereo and it was working without any problem.
Recently I bought an Airport Extreme to use it as my Base Unit connecting it to my DSL.
I followed the instructions of the Airport Utility, and it started working.
Suddenly, problems started happen the Airport express that was connected to the stereo , stopped working and it disappeared from the Airport Utility area , as it did not exist in the network. I tried to reset it but it did not appear in the Airport Utility page.
Apparently I have other problems with the private network that it created because I cannot use it because of problems with the password that was created. I can only use the network that I created for my guest...
I dont know if my problem is a configuration problem or there is problem with the equipment.
I read that other users where having the same problem with the Airport express , using non apple equipment as their base unit , but I thought that using the Airport Extreme was going to be compatible and no problems would happen.
What should I do?

Common Problem. Common solution.
Connect your Express via ethernet cable to the Mac while other network connections on the Mac are switched OFF.
After the Express shows up, change the settings of the Express to join the existing network. Take the appr. settings.
Unplug and reconnect your Mac to the network.
Check if the Express shows up in Airport Utility
Alternative solution:
Hardreset the Express to factory settings
(while on power push the Pin next to the audio plug with a paperclip. Plug out the Express still holding down the little button then replug the Express to power and release button)
After that, the Express will show up in the Airport Utility.
Make all needed settings.
I would prefer the first solution, its easier just to plug a cat5 cable.

I have Airport Extreme (802.11ac), which disappears from Airport Utility

Why does it disappear? I am not further than 50 feet from AE and it flips out! AE is connected to a switch from ISP located floor below my apartment that only works if set to "Bridge Mode" on network settings tab. I am trying to use connected 1TB drive to stream movies to AppleTV that is not 50 feet away from AE. When AE disappears from Airport Utility, I still have connectivity to web via Wi-Fi, but I cannot stream from HD. Very frustrating!!!! Running MBA with all software updated. Any thoughts?

Are you running Yosemite on your MBA? If so, this may be the culprit. There are a number of posts here describing this exact issue. At present there doesn't seem to be a solution. Even the latest OS X build 10.10.1 did not seem to resolve it. One theory going around is that this may be due to a conflict between the Bonjour protocol and the AirPort Utility. Some have tried temporarily disabling their OS X software firewall which appears to work ... BUT not consistently ... nor would I recommend it.

Airport Extreme keep disappearing from airport utility

Hello,
I have purchased recently an Airport Extreme and set it up as such:
- wired connection to my ADSL modem
- connected a 1TB drive by USB to the airport extreme
On top of this, I have an airport express that I use exclusively for itunes streaming to my stereo
Devices connecting to the Airport extreme are:
- one Windows XP PC (wired)
- iPhone, Ipad, Macbook Pro, all wireless
All firmware and airport utility versions are up to date.
First it works. All is connected, green lights, extreme and express detected by utility, USB drive visible everywhere. Then after a few hours, the following happens:
- extreme and express are not visible by utility on mac book pro (but still detected by utility on iPhone!)
- cannot stream music to express
- USB drive no longer visible from my Macbook pro
- shared itunes library no longer available
- green lights still on
- internet still on
The only way to fix it is to reboot the extreme.
Any ideas ?

I'm sorry to say that I've had this exact same problem. It's very frustrating because I lose the ability to stream to appletv and also to use wireless printing... the two main reasons I bought an Airport Extreme and got rid of my old router.
I will continue to have connectivity to the WAN but the airport utility on my MBP can't see any available airport devices. I thought it might be an issue with my OS, so I upgraded to Lion, but no change...
I've spent time searching the forums without success. I've also posted it to twitter. Hopefully, someone can help us? I'm wondering if the router hardware is bad or if it's a wireless driver issue with my MBP.

Airport Extreme randomly disappearing from Airport Utility

Dear All,
We've got here 32 AirPort Extreme Basesations, all with firmware 7.5.2. They are setup for Radius via Server Admin and linked to the OD Master. The basestations work fine except that they drop randomly from the list of basestations in the Airport Utility. They appear to work fine however it's very frustrating that remote access gets lost from time to time. The only solution then is to go under the ceiling and restart them. The units are configured identically and have it's own hostname defined via DNS and the tickbox is on for remote access via Bonjour.
Does anybody has seen this? Especially if configured via Server Admin to authenticate via Radius?
AirPort Extreme has no console login either, that would enalbe us to remotely login and restart the device.
Thanks,
Alex

I had the same problem. I figured out what the problem was when I answered the phone while I was using the computer. My 2.4ghz phone matched the freq with the AirPort, and it killed it every time the phone was on. It took me a few months before I figured it out. Try making a call when you can see the signal meter on the computer. If you don't have a 2.4ghz phone, ask your neighbor. It could be their phone.

Time capsule disappears from airport utility and finder while wifi still works

I am connected through my time capsule as wifi router.
Sometimes, while connected to the TC's wifi, the time capsule disapears from the finder and from the airport utility.
This leads to my time machine not backing up.

Thank you for your idea. However, after having imported the setup of the previous TC and having experienced problems, I had already done a factory reset and configured everything from scratch! Without using the profile. So I think we can safely exclude a problem connected with importing the older profile, which was in fact my first idea.
On the other side, I haven't tried your suggestion to give separate names to the 5 and 2,4 GHz wireless signals. I'll try this evening, as a last attempt before sending the TC back to Apple. BTW, I put my old TC back in place, and apart from the fact that the disk is noisy and almost full it works without a glitch. Which makes a software or configuration issue less likely, I believe.

Time Capsule disappears from Airport Utility, need to restart to find it.

I got a new Time Capsule for Christmas. Our household was using a D-Link router. The network was working fine for a Macbook, iMac, 2 x iPhones, PC Laptop and desktop. The two laptops are upstairs and connect wirelessly to the Time Capsule and an airport Express connected to stereo is set to extend the network.
Since Christmas the laptops are losing contact with the Time Capsule. At first I'd physically disconnect the modem and TC and the TC would reappear. Finding this annoying I rang Apple. I was told to edit locations in networks, add a location and basically reselect my network. I was told to monitor this, but that it should help. The TC went off airport utility again (the green light was still on), so i went through the process of edit location again and it worked. I posted the problem in macbook internet, thinking it was a macbook issue as my iPhone could still connect to the network and have internet. People suggested i do a power cycle. The next time the network crashed I performed a power cycle on every item connected to the network and turned on in correct order.
Tonight my macbook and pc laptop lost connection with the internet again. I had to physically take the TC and modem of power to get the network back again.
This is happening every couple of days, and I'm now sure it's a Time Capsule issue, this issue didn't happen with my D-Link router. I have my Macbook completing Time Machine Backups wirelessly, and when we lose connection with the TC, backups are delayed. Could the Time Machine backups be causing this loss of connection?
I'm going to call Apple and see if they have another solution, but was checking to see if others have had this problem and maybe a solution?

I just purchased a new Airport Time Capsule 3TB (ME 182 AM/A)
I broke my own rules.. as I saw one going really cheap and our currency is dropping like crazy so i thought I better get one .. stupid idea.. it lasted less than week and then refused to even power on.. It has gone back for replacement.
For your situation I think the problem is not the TC as much as it is yosemite.. but it is the combo.
Try the things I have suggested in this thread.. they have worked or helped other people.
Time Capsule keeps losing connectivity

"Allow this network to be extended" has disappeared from latest Airport Utility

I bought the new Airport Timecapsule (the vertical one) and have the latest version of the Airport Utility. Under "Create a wirless netwrk" there used to be a checkbox that said "Allow this network to be extended" As best I can tell, that option no longer exists (at least with the latest Airport Timecapsule). How does one extend this network? I have been using another Airport to extend my network and would like to continue extending it.

"Allow this network to be extended" is automatically enabled (and hidden) in the newer versions of AirPort Utility 6.x, so there is no setting needed for this.
The setup to "extend" is now much easier to configure with AirPort Utility 6.x compared to previous versions of AirPort Utility.
What device will you be using to "extend" the network? Do you plan to "extend" wirelessly, or "extend" by connecting the AirPort to the Time Capsule with an Ethernet cable? (Much better performance with the wired connection if you are able).

I am trying to setup my new time capsule but it is not working. after entering the airport utility and locating the TC, after I tell the program to continue, the unit just disappear and the setup menu says there is an error. Any idea of what is happening?

I am trying to setup my new time capsule but it is not working. after entering the airport utility and locating the TC, after I tell the program to continue, the unit just disappear from the menu and the setup menu says there is an error. I tried using the wireless connection, and also the cable, but none worked. Any idea of what could be happening?

What are you setting it up as.. join wireless network .. the very worst setup, it will disappear.. reboot the whole network in order modem. router TC.. clients and it will likely reappear.
Tell us what network setup you are using..
If you setup with cable to a computer completely isolated from the network with TC also isolated.. finish the setup of everything you want. .before update.. then plug it into the network. .then restart everything in correct order.. it will work most of the time.

I have accidentally "disconnected" from the Internet in Airport Utility. How do I reverse what I have done?

I have accidentally "disconnected" from the Internet in Airport Utility. How do I reverse what I have done? I clicked on the globe and clicked where it said "connected" and now it says "disconnected" HELP!

markwmsn, In the Airport Utility on my iPad I clicked on the globe at the top of the screen and over to the side there was the word "Connected". I clicked on it and it changed to read "Disconnected". At that point I started having Internet connection problems. All of the extremes (2) and expresses (6) I have spread throughout my home at first were green, but then began to either turn yellow, like the globe had, or disappear from the screen. Even though the globe remained yellow I went through the house and reset all the other devices. I was sure the problems were caused by my clicking on the word " Connected" and changing it to " Disconnected". I clicked on "Disconnected", but nothing happened. I called and wrote my ISP to ask them to reset the server serving my home. I got a call few hours later telling me that there had been an outage in my area, so I began thinking that perhaps there had been a coincidental occurrence of me clicking "Connected" and there being a service outage in my area. Needless to say I've decided to never click that word again for fear of the problem really being my actions.
If you can shed light on any of this, I'd be grateful.
Jay
