Airport express for isolated network diagnostic tool.

I have many isolated IP networks that I maintain. I am amazed by the network scanning capabilities of my iPhone. I use the various scanning tools when setting up wireless networks. My question is: can I use an Airport Express connected to an isolated network (no internet connection) via an Ethernet cable and connect my iPhone wirelessly to scan the wired network. I have been reading that the Ethernet port is only active when extending an existing wireless network. I would need to be able to set up a static IP address to get it into my network. I'm hoping this would work, much quicker and portable than a bulky laptop and computer bag.

I have been reading that the Ethernet port is only active when extending an existing wireless network.
It would also be active (802.11n AirPort Express only) if the Express is configured as a wireless Ethernet bridge. Apple calls this mode ProxySTA. However, in this mode the Express would not provide a wireless signal.
To get around this, you would need to use a second Express connected to the ProxySTA by Ethernet. This second Express can then broadcast a wireless network for your iPhone to connect to.

I really don't have an answer for that one. I guess that while trying to get things working correctly, I would use the most basic monitor I had which in your case would be the Eizon using the Thunderbolt port and adaptor.
When you boot into Safe Mode the startup is quite slow, but you should get the Apple logo and then the spinning gear below it (release the SHIFT key when it appears.) Then after a little more time you should see a gray progress bar appear below the spinning gear. When that disappears the computer will startup to a login screen.

Airport Extreme with Airport Express for extending WiFi Network...

I have had an iMac for quite a few years now and never needed WiFi until this week. I purchased a Macbook Air, an Airport Extreme and an Airport Express over the last 24 hrs. I opened the Airport Extreme first and followed the somewhat easy installation procedures. My iMac is wired via Ethernet cable to my Airport Extreme. The Airport Extreme is connected to a Motorola Cable Modem using Time-Warner. I also happen to have a Verizon Network Extender connected via Ethernet cable to the Airport Extreme. The spot where I most frequently would be using the Macbook Air, is about as far away from my iMac and Airport Extreme Base Network Router as you could be. The WiFi works, shows only one bar on the Airport icon. Consequently I want to plug my Airport Express in near this location to give me a better WiFi signal (and thus perhaps faster performance). I have read both the Airport Express Manual and the Airport Extreme Manual but neither talks all that much about the network extension function with the exception of connecting a stereo to an existing WiFi network. I am wondering what the specific steps are to add the Airport Express as a Network Extender. I also wonder if my Macbook Air will be able to access my iMac as the iMac is connected via Ethernet to the Airport Extreme vs. using the Airport Network. Any help will be most appreciated.

It was easier for "WiseJD" because he was using two Apple base stations, instead of your AT&T router.
I select Manual Setup, it just sits there thinking - I can't get into the actual set up.
So you see the Express in AirPort Utility, but when you select it and select "Manual Setup", nothing happens?
When setting up the Express to extend my existing wireless network (AT&T 2WIRE modem and Airport Extreme), do I initially connect the Express, via Ethernet cable, to the modem or the Extreme?
I'll guess that the AT&T device is connected to your broadband connection. Is the 2WIRE device either without Wi-Fi support or is that turned off? How is the Extreme configured, in particular in the AirPort/Wireless panel "Wireless Mode" setting and in the Internet/Internet Connection panel, "Connection Sharing" setting?
If anyone could provide a step by step process on exactly how to set up the Express to extend my existing network, I would be grateful.
I have very little experience with mixed-vendor home networking, but someone should be able to help.

HT3728 I do not need another wireless network but want to use the airport express for printer access only. Can this be done and how?

I do not need another wireless network but want to use the airport express for printer access only. Can this be done and how?

You can configure the AirPort Expess to "Join a wireless network" and enable the Ethernet port so that Ethernet devices will be able to connect.
In order to print from the iOS devices, you will need to have an application like Printopia installed on your Mac. The Mac must be active when you want to print.
More details here: Printopia - AirPrint to Any Printer - Print from iPad - Print from iPhone ...
There is a free trial available for Printopia, so make sure that it will work before you buy the AirPort Express.

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".

Constant Error While Setting Up Airport Express with Existing Network

I just bought an Airport Express for use with printer and existing wireless network (two original Airport Extremes). I can't get past the error msg below*. The AE shows in Airport Utility. I click on that and then "Continue". A window appears asking if I'm sure I want to "Switch" wireless networks. I assume I do since set up doesn't continue if I select "Don't Switch". But every time I try that it shows a spinning wheel and "Joining wireless network...", and un-joins existing wireless network (losing the two AEBS's), giving me the continued error msg. And on a few occasions Airport Utility can't see it, like now.
*Error Msg: "An error occurred joining the selected wireless network."
It's been a while since I've set up Apple's wireless devices but I thought it was easier now. The manual is ambiguous with "1) Open Airport Utility, 2) Follow the onscreen instructions...". If I could only get to that. Very frustrating for a device that's suppose to be so simple to set up.

Addendum: Now that I've plugged it in near the printer again Airport Utility can see it but can't read it's configuration so that I can set up the printer. How is this helpful with setting up a printer in another room/level if you have to set it up near your computer first because the two Airport Extreme's you have already set up (one of them, to create the wireless network, 8 feet away from the Express, and the other, to extend the wireless network, on an upper level, to reach the iMac) to give your computer a wireless network? So Airport Utility can see all three airport devices, the network/internet works and is extended to my iMac, but it can't read the Express device to set up the printer. Isn't that the point of the extended wireless network? And yet I can read/set up the Extreme near the Express. Now I have to lug the printer up two levels to set up the printer.

Adding a second Airport Express for Internet Share?

I currently use an Airport Express for two reasons - either for Airtunes (which is wonderful) and also for Internet Sharing...
My ADSL modem is connected to my eMac via USB and if I turn on Internet Sharing to Airport (in the Sharing prefs pane) I can access the internet from my iBook or G5... but this way, I lose Airtunes... so it's Airtunes or Internet and not both at the same time.
I'm thinking of buying another Aiport Express so I can keep Internet Sharing turned on and use the other one for Airtunes. Is this possible?
Any ideas appreciated.
Jonny

You would be better off replacing your USB Modem with an ethernet modem wireless router and connecting your Macs to that network rather than use a Mac based software base station.
Having said that, your problem arises as you have two wireless networks, the eMac based network and one created by the Airport Express (AX).
You can re-configure your Airport Express to join (as a client) the eMac wireless network and then you can maintain internet sharing and use Airtunes.
Ensure that the eMac is working as the software base station.
Hard reset the AX.
Configure the AX (probably best to do this from the iBook or the G5) to join an existing wireless network and choose the eMac wireless network.

Can't connect airport express to college network

I live in halls and I have an ethernet connection in my room which I want to send to my airport express and connect wirelessly on my macbook. The network is 802.1x secured, so I have to connect it each time if I've got the ethernet cable attached.
I've managed to get the airport express working as a wireless network, with airtunes, but it won't connect to the internet, I just get a 'server not found' error whenever I try to use the internet. The warning for 'no ethernet attached' has gone away, but I can't find anything else in airport utility which tells me that I'm connected to a network.
How can I get the airport express to connect properly and give me internet?

Welcome to the discussions!
Many schools prohibit the creation of wireless networks, so you might want to check on this before you try it.
You may want to temporarily connect an ethernet cable from your computer to the AirPort Express for the configuration. After the configuration is done, connect the ethernet cable to the wall jack and the AirPort Express.
Configure your AirPort Express (AX) as follows:
Open AirPort Utility, click Manual Setup
Click the Wireless tab below the row of icons to setup your wireless network. You want to "Create a wireless network" and enter your network name, security and password.
Then click the Internet icon
Look for the Connection Sharing setting at the bottom of the page and set this to "Off (Bridge Mode)"
Update to save changes and the AX will restart

Can Apple TV replace Airport Express as wireless network extender?

I currently have a 1TB Time Capsule plus an Airport Express 802.11n 5Ghz setup as a wireless network extender to the TC. I also use AirTunes on the AE tied into our home theater system. I'm contemplating purchasing an Apple TV and cannot figure out (after browsing forums and Apple.com) if the Apple TV can fully replace the Airport Express for both AirTunes AND as my wireless network extender? In other words, if I buy the Apple TV to I need to have it serve side-by-side with the AE, or can I move the AE to another location to even further extend the network range? Many thanks for any help on this topic!

Yes, that's correct. However, the OP wasn't asking if they could do that. They wanted to use the ATV to extend the network to other devices, and it won't do that. It will connect to the network even if the network runs off a single computer as a opposed to a router. But devices not connected to the computer or router can't connect to the ATV.

Airport Express for AirTunes. Problems.

I have a Windows XP computer and Laptop with a Linksys G wireless router in my house. Laptop connects to the router wirelessly and the desktop is hard connected to the router. Everyone is talking to each other nicely and I decided to invest an Airport Express for the sole purpose of playing itunes from my computer on speakers in another room.
I bought the Airport Express and have had nothing but disaster. I don't want to use it to create another network, just to "join" my existing network. So the first thing I do is plug it in with only the speaker connection plugged in. I have not plugged in an Ethernet cable or anything else.
According to the "manual" it is supposed to go solid yellow, blink and then go solid green. Because my home network is PW protected, I would have thought it could not "connect" to it on its own, but from just plugging it in to the wall outlet, I never get solid green, just flashing yellow, which apparently is bad.
Anyways, I use the software (updated over the net of course) to set up and it is looking for a "base station" (which is confusing to me because I don't have an Apple base station, I have a linksys router and the stupid Airport Express box plugged into the wall). At any rate, it "finds" the Apple base station and appears to treat it as an unsecured Apple network, with some funny id. I do "manually configure" and I tell it I want to use it for AirTunes, and I don't want to create a new network, I want to join it to an existing network. I give it the SSID of my home network as well as the 64 bit encryption key (that is not autogenerated, but that I manually type in), and that's it.
While I am able to get a message that it is ready to use (and I no longer see "Apple XXXX" as one of the available networks when I scan for available networks) the light on the Airport Express never stops blinking yellow, and it has done something to my home network because my laptop now is unable to keep a wireless connection to the router. I checked all my settings and they all seem to be ok, my desktop which is hard wired connects fine, but my laptop either won't connect at all, or connects and then drops. I have re-started everything including the router (not re-set, just unplug and plug back in) but my laptop now is totally not connecting and the Airport Express still doesn't work.
Sorry for the rant, but any suggestions?

Hello Birdman325. Welcome to the Apple Discussions!

Not necessarily. A flashing amber status light generally indicates that the AirPort Express Base Station (AX) is not connected to a network. Since the default configuration of the AX is a wireless Internet router, the flashing status light would be normal.
Anyways, I use the software (updated over the net of course) to set up and it is looking for a "base station" (which is confusing to me because I don't have an Apple base station, I have a linksys router and the stupid Airport Express box plugged into the wall).
The AirPort utilities are specifically designed to work only with AirPort base stations, so it would be normal for it to try to "find" base stations.
At any rate, it "finds" the Apple base station and appears to treat it as an unsecured Apple network, with some funny id.
Again, normal. Remember the default configuration of a powered AX is a wireless Internet router ... since you don't have it connected to the Internet, the utility will find it as a stand-alone wireless network that is unsecured.
While I am able to get a message that it is ready to use (and I no longer see "Apple XXXX" as one of the available networks when I scan for available networks) the light on the Airport Express never stops blinking yellow, and it has done something to my home network because my laptop now is unable to keep a wireless connection to the router.
Let's double-check your AX's settings ...
Perform a "factory default" reset of the AX
o (ref: http://docs.info.apple.com/article.html?artnum=108044)
To set up AirTunes on the AirPort Express Base Station (AX), either connect to the AX's wireless network or temporarily connect your computer directly (using an Ethernet cable) to the Ethernet port of the AX, and then, use the AirPort Admin Utility to check these settings:
AirPort tab
o Base Station Name: <whatever you wish or use the default>
o Wireless Mode: Join an Existing Wireless Network (Wireless Client)
o Wireless Network: <select the existing Linksys wireless network>
Music tab
o Enable AirTunes on this base station (checked)
o Enable AirTunes over the Ethernet port (optional)
o iTunes Speaker Name: <whatever you wish>
o iTunes Speaker Password (optional)
In iTunes:
iTunes > Preferences... > Advanced > General
o Look for remote speakers connected with AirTunes (checked)

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.

Can't Reconnect AirPort Express to my Network

Hello all,
So I have somewhat of a problem here, and I'm hoping to get some input. Basically, my house is 3 stories. In the basement, we have a room with all of our networking hardware (our modem with an AirPort Extreme router). On the 2nd floor of the house, there's an AirPort Express in the kitchen. On the 3rd floor, there was an AirPort Express in my parent's room, which I just recently unplugged to move to my room (I needed an extra ethernet port source ). Anyways, in AirPort utilities, I had everything set up perfectly fine. Both AirPort Expresses were set to "Extend Network," which is how we wanted it. Now, for some reason, the AirPort Express in the kitchen got the error message "AirPort Express was previously part of your network." So, I clicked "Forget" and was just going to set it up again by selecting it from the drop-down menu and going from there. The only thing is, it's not there... I don't know how moving the Express on the 3rd floor led to this, but it did. Any ideas on how to get it back? There's all green lights across the board (AirPort Extreme in the basement, AirPort Express in the kitchen, AirPort Express in my room). The connection in the kitchen is a bit iffy, but in all other spots across the house it's 100% fine.
Thank you!

Can't connect Airport Express wirelessly to network so that AirTunes and internet are available simultaneously

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.

Love airport express for music throughout the house but it goes dead from time to time

Airport Express for music just goes dead
is there a quick fix to this

You don't really want 2 wireless networks. After you get the Linksys set up, you will want to configure the AirPort Express (AX) to join the wireless network created by the Linksys base station. You will then have one wireless network that provides Internet and wireless music streaming.
Use the directions in KB 302153, AirPort Express: How to join an existing wireless network in client mode to configure the AX.
