Airport Express joined to network but not discoverable

I have two airport expresses - an older b/g model and a newer draft n model - both on their latest firmwares.
December last year I joined them both to the wireless network in a new place and both worked fine.
I hadn't used either since December - so there my have been some airport utility and itunes updates since then.
Today I plugged either one in and it synched with a green light immediately - however neither could be found in itunes or airport utility.
I have tied configuring them - both wirelessly and via ethernet cable.
I have tried a hard reset to restore to factory default and then configure them.
They can only be found by airport utility and iTunes under these circumstances:
1. After a hard reset to factory settings - awaiting initial configuration
2. Configured as it's own wireless network
3. Joined to the existing wireless network via ethernet only (WiFi off).
If I join to existing wireless network as I need to do the device is not discoverable.
I input the correct credentials and then the device reboots - at this stage it drops out of the airport utility and never gets picked up by it even though it reboots with a green sync light, indicating it is now joined to the network. Only way to still see it after reboot is if it is still attached to computer over ethernet. As soon as ethernet is disconnected it dropsout.
I would think it was not broadcasting a wireless signal were it not for the fact that it does work when set up as its own wireless network, and also were it not for the fact that it was doing it to two different airport expresses, both different models.
I have two laptops - one on leopard and the other on snow leopard and still no luck- so I don't think it is an OS update issue.
I have never had trouble configuring AEX joined to an existing network before and they both were working December last year.
So in summary: two different model AEX displaying the same behaviour, two mac laptops with different OS' used to configure, tried wireless and ethernet configurations, reboot after configuration gives green sync light but is not discoverable in itunes or airport utility. Airports ARE discoverable when broadcasting their own wireless network or joined to network over ethernet only. Airports are discoverable after hard reset to factory settings but become invisible when correctly joined to an existing wireless network after reboot.
Please help - it is driving me crazy!!!

I'm not trying to set it up as a network.
I just want to be able to play iTunes on my hifi.
The Airport Express is currently sat right next to an Huawei HG532 router with a solid green light.
However both iTunes and Airport utility says: "Airport Utility was unable to find any Airport Wireless devices.... make sure it's plugged in etc...."
Never had a problem before, but i've just plugged it in after a 4 month absence.

Airport Express works with Skype but not with internet

Hi,
I recently bought some new Airport Express' for my company. However, when plugging it in we seemingly get full access, but only Skype seems to work. If I do a search on the internet it can sometimes look like it find the address after a long while, but don't manage to open the page. E.g. writing www.google.com in the search field doesn't give access to that page.
I brought them home to check if the Airports worked there, and they did. No problem. But at the office the Airports don't. If I connect the same plug which is connected to the Airport into the MAC / PC, then I have full connection to the internet.
What to do?

After Grant pointed out the DNS thing, I started to check that part, and I noticed something funny. I called Apple Support regarding the problem, and now it's solved
Here is my experience:
1. My Airports worked fine when home, but not at work.
2. Checking the LAN DNS addresses I received three addresses. 2 in the 158.xx... range and one in the 129.xxx... range.
3. The Airport Extreme and Airport Express does only support two DNS addresses, and since the two 158.xx... DNS addresses came first in that range the 129.xxx... was left out.
4. I manually changed one of the 158.xx... addresses to the 129.xxx... address I got on my MAC / PC when I connected directly to the wall and did a "ipconfig /all" on the PC. The three same addresses is listed under network - airport on the MAC.
5. Now suddenly it all worked. This due to that the two 158.xx... addresses seamed to be internal addresses, and the 129.xxx... address was from outside delivered from our operator.
Summarized:
When you receive 3 DNS addresses you MAC and PC can handle it fine, but your Airport not. Find all your DNS addresses and write them down. Enter Airport Admin Utility and do a manual setup. Change one of the two equal address to the third address. Most probably listed as the last DNS address when you are connected directly and type e.g. "ipconfig /all" on your PC or you enter the network settings.
Best regards,

With my Airport Express, I can join the network but not extend it.

I just bought a new Airport Express to extend the network I have setup with my Airport Extreme. At first, it seemed the Express was unable to get a correct IP address, I think because I had my DHCP server running from the cable modem, and the Extreme was just acting as a bridge. I switched the Extreme to run a DHCP server and now the Express correctly receives an IP address. However, it still tells me that it cannot extend the network, but gives no details why. It just tells me to make sure I have the correct password and to be sure I am in range.
Clearly I am in range and have the correct password, because when I switch to "join network", all works fine. Though when I do switch, I still get an amber blinking light and Airport Utility still thinks the Express is in Extend mode. When I unplug and replug the Express, then it comes up with a green light and Airport Utility shows it in Join mode and all works fine.
I am thinking there might be something wrong with my Express and am considering exchanging it. Just wondering if anyone has any ideas as to why this may be happening?
Thanks.

However, it still tells me that it cannot extend the network, but gives no details why.
Suggest that you check your AirPort Extreme to make sure that you have enabled the wireless network to be extended.
Open AirPort Utility, select the AirPort Extreme, and click Manual Setup
Click the Wireless tab below the row of icons
Just under the setting for Wireless Network name......make sure that there is a check mark next to "Allow this network to be exended".
Update to save changes
Now, try the configuration with the AirPort Express set to "Extend a wireless network"

Airport Express Shows in WAN, but not Wireless

I have an old Airport Express and a Time Machine (and Powerbook 13" 2011 model ... OSX 10.8.2). I have been using the TM fine for quite some time now. I used to use the AE, but packed it away for the last two years. Having just gotten a new stereo, I would like to play music via the AE again, as I used to.
However now I cannot get the AE to show up in Airport Utility. If I plug it in by Ethernet, it shows up fine and plays music. But the moment I unplug the Ethernet, I lose connection. I have tried to configure as Extend a Network and Join a Network, and the same thing happens with both ... music plays fine with plugged in, but cannot get a signal with wireless. AE does not show up at all on AU on wireless. Resetting the AE has no effect. The AE light is solid green the whole time.
I suspect I am doing something really basically wrong and dumb, but cannot figure it out at all. Any advice would be greatly appreciated.

ok here's an update.
now my airport express turns to green automatically (only in my room)
it will still be blinking amber anywhere else
so the problem is still not solved.

Airport Express Join Wireless Network Disables Ethernet

I have one of the the older Airport Express (firmware 6.3) and I'm trying to use it to connect a non-wireless machine to an existing network.
Act as a single Wi-Fi interface to any computer or almost any other devices such as game consoles that has an Ethernet port but doesn't itself have built-in Wi-Fi
If I choose "join a wireless network" it appears to disable the ethenet port. Any ideas what I might be doing wrong.
My Setup
ADSL Modem ------ Time Capsule ---[wireless-g]--- Airport Express ---[ethernet]---Computer

Unfortunately, the Ethernet port is disabled when you configure the older AirPort Express version that you have to "join a wireless network"
It can be enabled in the newer 802.11n version, which uses firmware 7.x.x. Sorry, not possible up update the Express that you have since hardware changes were made in the 802.11n model.

Airport Express joining a network - Please HELP!

I just got an AirPort Express 802.11n Wi-Fi, and I am trying to make it so I can get better connection to the internet from different floors of the building wirelessly. When it decides to actually read the Express I can get to the point where it is asking me for the network I want it to join and I select it and put in the password (which I know is correct), but when I hit continue absolutely nothing happens. Its as if I did nothing. So I'm stuck because it doesn't even tell me if I did something wrong or if it wont work or anything.

Hello feldmane. Welcome to the Apple Discussions!
If your goal is to extend an existing wireless network with the 802.11n AirPort Express Base Station (AXn), then the option to "join an existing wireless network" would not be the correct choice. If the wireless router you want to extend is another AirPort, then you should use reconfigure them into a Wireless Distribution System (WDS) (for 802.11g) or "extend a network" (for 802.11n). If the other wireless router is NOT another AirPort, then extending with the AXn most likely will not work as very few non-AirPorts are WDS-compatible.

Can my airport express join my network via Belkin Router?

What's up everyone?
I have a question regarding my apple airport express. Is there any way to get this my airport express to join my belkin network? My current network is being run by my Belkin N Wireless Modem-Router(model# F5D8633au4A)and i can't seem to get my airport to join it properly. Everytime i try to install it, it seems to mess with the signal my laptop gets and the AEX doesn't even connect to the network. The best i've gotten is it shows up on itunes, but i can't select the remote speakers.
For now, i just want my AEX to be able to join wirelessly so i can use airtunes, but would it also be possible to set it up so that i can plug my xbox into it so it can go online?
Anyone have any experience setting up the AEX with a belkin router?

Hi:
I do not have a Belkin router, but have basically the same problem using a Linksys 54G 802.11n router.
I can setup my HP laptop/printer/router as a wirelss network, but cannot get my AE to join that network as a client, wirelessly. IF, I have an Ethernet cable connected from the router to the AE, I can configure the AE, get the solid green LED on it, etc., and play music out of external speakers, but all falls apart whn I disconnect the Ethernet cable from the router to the AE, even though Airport Utility has things setup as a wireless connection.
Have you tried setting up an Apple ad-hoc network from the PC/laptop to the AE and speakers ? See if you can do that. If so, you can play music wirelessly thru the AE/speakers from iTunes (the LED will be a flashing Amber). The trick is that you have to wait about 1-2 minutes duing the config in order for the AE to establish the connection where it (the ad-hoc network) shows up in your system tray network list, when the icon is clicked. The Appel ad-hoc network will have a name like Apple XXXXXX, where the XXXXXX are 6 (of the 12) digits from the AE's MAC address (listed on its label).
If this works, my guess is that the AE is OK, and the problem is getting your AE to join your already existing Belkin network (in my case, LinkSys network).
I was at one of "Apple Genius Bars" last night probing this problem, and they feel that this is most likely a compatability problem between the AE and non-apple routers...though I do not feel that there should be a problem, or they shouldn't be selling the product claiming that it works with non-apple products.
The guys at Apple suggested that I call Apple for Tech Support at:
1-800-APL-CARE (1-800-275-2273)
There shouldn't be a charge, though the guys at the Genius Bar said that if they try to charge, to raise a big stink over the phone since the
Apple product is not working as claimed !
Another issue: What level of encryption are you using with your router ?
WEP-64, WEP-128, WPA, WPA2 ???
This greatly affects how easy (or hard) it is to add the AE to your existing network. From what I have learned, the lower the level of encryption, the harder it is to add the AE to the network, since it is an older, less-capatible standard.
Let me know if you find any answers...

Airport express working on mac but not on pc

My airport express works wonderfully on my Macbook Pro, but I would also like my PC to connect to the same network. I have tried everything that I have found online, and the PC will not recognize or "find" the airport network. Does anyone have any suggestions?

Ok, thanks for the additional info.
I suggest trying the following:
o Temporarily disable the WPA/WPA2 Personal wireless encryption, and then, check to see if any of the XP devices can now access the network/Internet?
o If they can't then, while the encryption is still disabled, change the radio mode on the AX to a non-"n" one, like "802.11g only." You can access this mode, by holding down the <Option> (Mac) or <Control> (PC) key prior to selecting the mode within the AirPort Utility. Can they access the network/Internet now?

Airport Express: Internet Access Works But Not "Seen" in Admin. Util. ??

Hi All --
I have a friend with the set-up described below and a seemingly impossible problem. he's asked for my help, and so I'm asking for yours, because frankly the situation just has me stumped. Here goes:
Set-Up & Other Relevant Facts
• DSL connection comes out of the phone jack and goes to a Westell model 6100 modem.
• From there, a short Ethernet cable goes to a Linksys 5-Port Workgroup Switch.
• Two Ethernet cables exit the Linksys Switch: one goes to a PC, and one goes to an Airport Express (AX).
• From the AX, a USB cable goes to a printer (a Brother 1440 laser printer).
• The AX is only about 10 feet from his PowerBook G4 15-inch and he gets a full (four-bar) signal on Airport menulet at the top of the screen.
• When he first set-up his system, the G4 and the Airport did set up the Brother printer (using the Airport Setup Assistant), and the Brother is listed as a printer on the G4's printer window or such.
• Both the G4 and the PC access the web fine via this setup (the G4 wirelessly). In System Preferences > Network, the Airport Network is listed, and it says "Airport is connected to the network Apple Network 6c6c1. You are connected to the Internet via Airport."
Problems
• When the Airport Admin Utility is opened, no Airport Express appears at all, even when "rescan" is repeatedly clicked.
How can this be? How can the PowerBook be connecting wirelessly to the Web through the Airport Express, but the Airport Express no be "seen" by the Airport Admin utility?
• In addition, although web surfing is possible for both PowerBook and PC, neither computer is able to successfully print to the Brother 1440. When he tried printing from the PC, he got the following error messages:
[Status for LPT1]
Result=(02)The printer on this port is not responding.
Status Line=BUSY:H,ACK:H,PE:H,SLCT:H,FALT:H,SLIN:L,HBSY:H,INIT:H,STB:H
Later, it seemed that printing from either computer would start and then stall, flashing a variety of different signals about spooling or "printer busy" and the like, all of which appeared to indicate things just weren't working right..
Anyway, the initial questions we're dealing with are the ones in bold above. The printer issues are probably are related and they can be addressed secondarily.
Any and all help with this will be greatly appreciated. Thanks everyone.

Thanks for your reply- just to re focus my problem- I
have no issue with getting a wireless network "green
light"
Which is the cable modem correctly giving the Express an IP from your ISP's DHCP pool of numbers.
- my issue is I can't stream itunes or get a
usb printer to work off the xpress USB port.
I have checked everything as my posts explain- The
reason I have been looking at this thread is I have
never been able to see the airport in a "scan" per
JDee post.
That is odd and doesn't happen on my wireless network!
Nor have I read in any post that an extra
ip address is necessary
All routers have at least two IP's - an external and an internal. When the router acts as an internal DHCP server it hands out many more IP's. Your Express gets one external IP and the default internal one is set to 10.0.1.1 and the first IP handed out is 10.0.1.2, etc.
However I have seen different subnets- from dncp
server.
Are you talking about the external IP's that your ISP is randomly assigning without your control? Are you talking about the different ways you can configure the internal DHCP numbers? If not there's something else going on. Everything on Douglas internal network should have an IP from the Express DHCP server vs. JDee's internal IP's should all be assigned by the modem/router DHCP server. Once you have everything on the same network numbers AirTunes, printers, and Airport Admin Utility lists just work!
Hey look I really appreciate your help here in
anyway- I'm really stumped. I want to stream music
really bad... and just don't see why it won't work-
its drving me crazy...
I enjoy a good challenge, especially when they are solvable. After trying all the possible software and connection possibilities there's always the chance it's been a hardware failure all along
What IP number does your computer have and what number does the Express have? If it's a router it has two IP's!

Airport express connects to internet, but not print server

hello all. i hope someone can help me with this. 2 days ago, my wife was able to print using her ibook/airport expess setup. today, the network diagnostics has this message: "network diagnostics was able to connect to the internet but not to the server EPSON Stylus CX3800.pdldatastream.tcp.local. this could be caused by problems with the server, or an internet problem between this computer and the server." she says this happened when she turned it on. what could be causing this? any and all help welcome. mcrat

You can reset the AirPort Express (AX) following the directions in Resetting an AirPort Base Station or Time Capsule FAQ.
Then you can use AirPort Utility on your computer to configure the AX.

Airport Express connects to MBPro but not to my Lenovo or Blackberry

I just got the new Apple Express and here's my setup:
Optimum online cable modem --> Airport Express [Note that I don't have a regular router or Apple Extreme]
Airport Express software installed on my Macbook Pro 2010 (Snowleopard) to set up the wireless network. After struggling for a few hours, I managed to get my MacBook Pro to connect to the wireless (with and without password). However, I am unable to connect my work laptop (Lenovo T410...my wife has the same and it won't connect either), nor my Blackberry Bold.
The problem is that the Lenovos and our Blackberrys detect the wireless connection, but fail to connect (or acquire a network address). I am constantly getting "limited or no connectivity" message.
At first, I thought it was because of my WEP / WAP2 security, but I disabled my security and am still facing the problem.
I know this is a common problem, have searched forums extensively but have not yet found a solution. Any help will be much much appreciated.
Cheers

I've been having similar issues with a Blackberry 9650 (5.x) but I'm using the Apple AirPort Extreme with an AirPort Express as an extender, it seems I've tried everything to get it working (change to WEP, WPA/WPA2, Mixed Mode, 5.0 GHz, etc.), but nothing seems to work.
Can you see the Lenovo or Blackberry in the DHCP logs of the AirPort?

Airport Express USB Printer Visible, but Not Printing

I've connected my printer (HPc7260) to my Airport Express. It is visible on the network. But print jobs get stopped and the print utility says the printer is offline.
Any thoughts?
+This question is also posted in follow up to a thread I started earlier, which was answered helpfully by Duane (thread: How Setup Airport Express for Wireless Printing to HP Photosmart C7280) Sorry for redundancy and clutter. I hadn't followed up on the old thread for a few days. Thought it might not get another response.+

Solved.
A restart, followed by reselecting the printer in the print dialog got the job done.

Airport Express prints from Vista but not Leopard

I have an airport express (G model, not N) which I've started to use as a print server. I'm using a Samsung ML-2510 printer. Everything worked just fine about yesterday, but today I'm finding that the Airport Express will only print from windows vista. On my wired macs nothing happens and it sometimes tells me the printer is busy, when it's not. On my wireless mac, an iBook, it tells me the printer is offline.
I can print from mac using a D-Link print server, but not from my airport express. Windows Vista has absolutely no problem with airport express. I find this a little odd.
Is there any way to fix this? I don't even know how it broke. I would like my airport express to work with my macs again.

Connecting to wireless thru airport express (joined home network)

I have a wireless router in my bedroom, which is the source of internet connection.
I use the airport express to join this connection, and this airport express is now plugged in my living room.
the name of the wireless connection is "my_name room".
the name of the airport express is "my_name airport express".
i cannot locate the "my_name express" on my devices, including macbook pro, and iphone 5.
i can only locate "my_name room".
is this normal for using airport express as an extension of a network ?
thanks in advance.

What are the benefits of extending a wireless network then ?
Unfortunately, you are not extending your wireless network since the Express is not compatible with your router for that purpose.
The benefits to extending a wireless network...assuming that your Express is working with a compatible wireless router.....are the same as "joining" with the added plus that the Express is also providing more wireless signal, so the wireless signal strength will be provided over a greater area.
Another question is, the only purposes of joining a wireless network are for AirTunes, and remote printing ?
As I mentioned above, the Express can be used for AirTunes or a remote printer when it is configured to "join" a network. It can only "extend" a wireless network when it is used with another Apple product. In that case, the Express is configured to "extend a wireless network".

HP Officejet Pro 8600 - Printer is on Network but not Discoverable with Typical Discovery Method

Hi all.
I need help! I have fought with this printer (HP Officejet Pro 8600) for about an hour. The error message I get says that the printer is on my network but is not discoverable using the typical network discovery method. I can set it up using the IP address (and will), but we frequently reset the router, and I don't want to deal with the printer everytime I do this. I figured it was something with the Windows firewall. I temporarily disabled it and tried again - nothing different. I am also running AVG free edition, but it does not have a firewall. Any help is appreciated! Forgot to add... I'm running Windows 7.

Hi Kelly,
The printer should be able to reconnect to the router by itself after the router is reset. Why do you have to reset the router? It might be part of the issue with the printer.
There are multiple ways for the software to discover the printer. There could be a setting in the router or even software services in the computer that are causing the normal methods to not work.
After you reset the router, does the printer not reconnect? The blue wireless light would continually blink if the printer cannot reconnect to the router after the reset.
I was an HP employee.
