AirPort Express disappears for network until it is rebooted, Arp problem
Hi,
I have just configured my AirPort Express as a remote speaker for iTunes.
After the AirPort is powered on I can access it via AirPort admin tool and from iTunes.
After a while, the AirPort can no longer be connected to, either by the admin utility or iTunes.
I am running firmware 6.3, and have reinstalled this version. The unit is around 4 months old
Anyway, what I have noticed is that the AirPort does not seem to respond to TCPIP ARP requests which means that if a computer flushes or expires its ARP cache it will not be able to connect to the AirPort.
A network sniffer shows the ARP packets being broadcast on the network but there is no response from the AirPort.
I can see that the AirPort sends out ARP requests after a reboot, but will not respond to ARP requests that other machines on the network send out.
Any ideas?

I have had the AU running at all times but the AX's would still disappear.
The latest think I have tried is "not allow wireless clients" check box on the AX units. Since I have done this, I have not had an AX actually disappear. I now just deal with music skips and chops, if I turn on more than 2 units.
I also realize that using the AX units in for an Ethernet bridge is actually slower than using the Wireless G adapter. I use wireless to transfer shows on Tivo.
At this point, I am back to square one. The AE router gives me no benefits over a linksys or other wireless router. I can't use WDS, I can't use Ethernet Bridge.
The next thing I will try is to go back to Wireless G adapters on all the Tivos, then "allow wireless clients" and the AX units. At least I will get the WDS feature and be able to extend the range on my network.
I am guessing, if I just set up the AX units they way they were before (non-wds) and use the Tivo Wireless G adapters (essentially the way my networks was originally set up minus the AE router), that everything will work fine.
I would think Apple would do a better job before marketing products to do this.

Airport Express Disappears From Network
I have my Mac connecting to my Airport Express (6.3 firmware) via a Netgear DG834G wireless router.
If I reset the Airport Express, then it can be seen by the Admin utility and iTunes, but will disappear after a short period of time ( say 10 minutes ).
However even when it is not visible to the Admin Utilities scan I can still connect to the AX by its IP address, reset it and it will re-aooear again for a short duration.
Any ideas?Same problem here...and yes also after receiving a new router from my provider.
The weird thing however is that when I use Airfoil in combination with Winamp (or whatever media player) there are no problems at all.
So the problem is for me clearly related to iTunes and the admin utility.
When using iTunes I have exactly 1 hour and 17 minutes music.
I have however no idea if Airfoil has a different way of comunicating with the AX (name, IP address, protocol) -
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. -
Apple Airport Express disappears
Hello,
I do not think you live in the Bermuda Triangle and it is normal that my Airport Express disappears No, unfortunately not.
I would like to use my AE to stream music, they've also integrated it with the Airport utility into an existing wireless network.
10min long this works well, music will play properly, then "disappear", AE, and I can not in iTunes, select speakers, yet she finds the Airport Utility.
Oddly enough, the pilot light is lit on the AE still green ie actually it should work.
I use a router ASUS RT-N56U and use Windows 7
Airport Utility software version 5.5.3
iTunes version 10.5.2.11
p.s. Sorry for my bad english, it comes from Google Translate german-englisch :-)See if this doesn't help.

So. I've had an Airport Express extending my network for months. Lovely. I have an Airport Extreme base station upstairs. Suddenly the Express lights up yellow. Airport Utility cannot find it. I choose "forget". Try to reset everything. The base station still cannot find the express. Any advice is appreciated. Really ticked.
Welcome to the madness!
Take a look at this forum discussion...
http://discussions.apple.com/thread.jspa?threadID=1447946&tstart=15
It seems a very large number of users are experiencing this Cheshire Cat act; the disappearing Airports of all kinds with Airport Utility.
I am hoping for a major release or something from Apple to help us all out. For now, Apple's claim to 'effortlessly set up wireless networks' is untrue.
My AX disappeared exactly as yours did when I tried to add it into a network created by Airport Extreme Base Station- both brand new out of the box n types. Right now my AEBS works fine, but the AX is unconfigurable and unrecognizable despite resets etc. I used WAP security when I first set up AX, but then it got stuck on amber and that was that, resets, warts and all.
This whole issue needs a real sort out. -
How do I remove an unwanted Airport Express from my network?
I have been using a Time Capsule for several years. I am having trouble backing up to my Time Capsule. I have discovered an unknown Airport Express in my network. I've changed networks, added passwords to the network, etc. How do I remove this unwanted Airport Express from my network? I think he is wreaking havoc with my system!! Help...
Maybe this is an issue I should consult my ISP about??
No question about that. If you can "see" Travis's device, then he can likely "see" your Time Capsule.
I'm just concerned that whomever the APExpress belongs to could be changing settings on my computer or Time Capsule that would cause the issues with me not being able to backup.
Make sure that you have a Time Capsule base station password. Unless a user has that password, they might be able to "see" your Time Capsule, but they cannot access any of the data on the Time Capsule or change the settings.
Open AirPort Utility, click on the Time Capsule and click Manual Setup
Then, click the Time Capsule tab below the icons to see the device name and password for your device. Make sure that you have entered the password and confirmed. Click Update if you have made any changes.
The message I get is "The backup was not performed because an error occurred while copying files to the backup disk. The problem may be temporary. Try again later to back up. If the problem persists, use Disk Utility to repair your backup disk."
I am not sure what this error means, because I cannot duplicate it here to test.
If it were me, I would try this "fix".

Since updating to Yosemite my airport express (used for airplay) connects for a short period then drops, the error message "An error occurred while connecting to the AirPlay device “Kitchen”. The host cannot be reached." Has anyone else had this problem
I'm having the same issue. Haven't found a workaround. I use a main TimeCapsule as my main router, also have another TimeCapsule that extends the network, three Airport Express and an AppleTV. For whatever reason, the two AirportExpress that I have in a different rooms cut out. I only have 600 square foot apartment so it's not that big, the signal should be strong enough. Airport Utilitiy reports the signal strength to be strong on all devices.
I'm using all new equipment, a new MacPro for my music, new TimeCapsules, new Airport Express, new everything with the latest Yosemite software. Very frustrating. My Airplay used to work very nice and now I'm constantly having issues and restarting my network. I did a fresh install of all my software on my MacPro when I got it in January so it's not as if it's an old machine with old software, everything is new within the last 6 months.
The only workaround I found so far is to unplug the devices and to plug them back in. Since upgrading to Yosemite, I'm restarting my Airport Express at least twice a week. Very annoying. -

I can't connect Airport Express wirelessly to network so that AirTunes and internet are available simultaneously. My old AE allowed this but can't make the new one work that way.
In your instructions, you say to use the same encryption type as the router has set up. well, I am using the WEP 64 bit encryption and the Airport Utility does not have this...it has 40 bit. Is this a problem, or do I have to be using a the same type of encrytion ?
WEP is available in either 40 or 104-bit, but is usually "advertised" as either 64- or 128-bit respectively. For example, 64-bit WEP uses a 40 bit key (also known as WEP-40), which is concatenated with a 24-bit initialization vector (IV) to form the 64-bit RC4 traffic key. So, WEP 64 on the Linksys & 40-bit is equivalent.
What concerns me more is the loss of bandwidth performance you are experiencing when connecting the AX. When the AX is configured as a wireless client it is acting just like any other wireless devices (computer, laptop, printer, etc.) and not like another router. This should cause little or no bandwidth loss. True the more secure the wireless encryption used WPA2 vs. WEP, the more overhead is required for security, but the differences you are seeing seem excessive.
It is very possible that you may have some form of Wi-Fi interference in the immediate area that is preventing your Linksys from providing a good clean signal.
I suggest you perform a simple site survey, using utilities like the following to determine potential areas of interference, and then, try to either eliminate or significantly reduce them where possible:
For Macs:
o MacStumbler
o iStumbler, or
For PCs:
o NetStumbler -
Airport Express: Extend a network and do Airtunes at the same time?
Hi, I'm trying to organize the people in my apartment building to share an internet connection wirelessly.
The connection is originating from a friend's apartment; he has a Linksys router, probably "g" flavor.
We're going to put one Airport Express in a neighbor's apartment to extend that.
I have an Airport Express connected to my stereo which I use only for Airtunes.
So I'm wondering: can I connect my Airport Express to this network and extend it and ALSO use it for Airtunes?
Also: Can I prevent my neighbors from seeing my Airport Express for Airtunes purposes? IE, I don't want my stereo to show up in the "multiple speakers" drop down of iTunes for other people connecting to the network...
Hope there's a way to work this out...can I connect my Airport Express to this network and extend it and ALSO use it for Airtunes?
In order to extend the wireless range of the Linksys router, you would have to configure your AX and the Linksys in a Wireless Distribution System (WDS). Unfortunately, very few non-AirPort router are WDS-compatible. The few Linksys models that are reported to be compatible are the WRT54G & WRT54GS.
If you can create a WDS, streaming iTunes should not be a problem.
Also: Can I prevent my neighbors from seeing my Airport Express for Airtunes purposes? IE, I don't want my stereo to show up in the "multiple speakers" drop down of iTunes for other people connecting to the network...
No, but you can establish an iTunes Speaker password so they would not be able to stream to it. -
I just bought a new Motorola modem. Do I need to reconfigure my Airport Express? For some reason we have WiFi even though the amber light is blinking.
Typically, when changing out networking hardware, it is always a good idea to perform a complete power reset of all of your networking equipment.
I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Continue with step 2 in the first set of steps.
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results. -
Airport Express added for iTunes
I've got my AEB up-and running in a N network.
Now I would like to add an Airport Express wirelessly for Airtunes purposes.
I've read the document "Designing AirPort Networks Using AirPort Utility" and I'm still not sure about the configuration.
How should I configure the Airport Express to connect to the existing N network.
There are several possibilities: remote, relay, WDS, extending ...
Which one to choose and why?
Your help is very much appreciated. Thanks.William,
I just added an Airport Express N w/ AirTunes to my existing Network that has an AirPort Extreme N. I initially added it as an extension to my network, but my Internet connection dropped frequently. This was because the Extreme and Express where physically located too close to one another; therefor I switched the Express to only just join my existing network instead of extending it and haven't had any problems sinces.
I think it really depends on the distance your stereo is from your current base station. If your stereo is on the other side of the house extending it would probably be beneficial; however it they are in the next room from one another I would select to only join the existing network instead of extending it. -
15" MacBook Pro randomly loses connection to my AirPort Express wi-fi network.
My 15" MacBook Pro randomly loses connection to my AirPort Express wi-fi network. I have to switch off wi-fi on my Mac then switch on again to reconnect. Any reason why this random occurrence keeps happening which never happened before? Any solutions and fixes would also be welcomed.
JazzIn the airport utility, you can alter the radio modes... and change the channels from automatic to a manual one.
Hold down the Option key, and click on your wifi icon, it will tell you what channels are currently being used on your OSX. -
Is airport express needed for an airprinter
is airport express needed for an airprinter? I'm confused about the concept. Pls help
The concept is that you need a printer that is AirPrint compatible if you want to be able to print from an iPhone or iPad, etc without adding additional software.
Apple updates the AirPrint compatible list from time to time, but you can get a general picture of AirPrint compatible printers here:

On my new iMac, mail has no sound after waking from sleep. If I select do not wake for network access in general preferences, the problem does not occur. Anyone have an idea on how to fix this? Thanks --
Same here on an older iMac since Lion. Thanks for the uncheck wake for network access tip though, it doesn't do it either in that case, I will leave it that way.
