Airport Express won't work simultaneously with Internet Sharing

I just purchased two Intel-based iMacs (each with standard configuration including Airport cards), and 1 AX. I placed iMac #1 in Room #1 (near my cable outlet), iMac #2 in Room #2, and the AX in Room #3, along with powered speakers. Using an Ethernet cable, I connected iMac #1 to my cable modem (and its broadband internet connection). I then turned on Internet Sharing, so that iMac #2 now connects to the internet through iMac #1. I also placed the AX in another room and connected it to powered speakers. Here's the problem: Airtunes only works (i.e., the AX-connected powered speakers only show up in iTunes) when I turn off Internet Sharing. The powered speakers "disappear" from iTunes as soon as I turn Internet sharing back on.
Is there any way to fix this?

I assume that you are having this problem with iMac #1 which is doing the sharing... Perhaps this happens because iTunes will not cross subnets.
Even though iMac #1 exists on both subnets (the Ethernet one and the one created by Internet sharing) it appears that iTunes is not using the subnet created by Internet sharing. Therefore it won't cross between the Ethernet subnet and wireless subnet.
The solution is to get an inexpensive wireless router and use that instead of iMac #1 to create your wireless network.

AirPort Express won't work with 7.0.2

Everything was fine til I bought a new Shuffle. It made me upgrade to 7.0.2, now my Airport Express won't work. I have firmware 6.2 and just uploaded all of the newest updates from apple.com for it (AX). The security is off on my network and the AX is connected with a green light. Still no option to choose my home stereo which is hooked up to the AX. HELP! I have spent all day trying to get this to work!!!!

My Airport Express when it is setup to extend my network while plugged into Ethernet will Create a network under settings
This is the correct setting to "extend" the network using an Ethernet connection. Technically, this is called a "roaming" network.
If I change this to Extend A Network it doesn't work properly.
This is because "Extend a wireless network" is used only when AirPort devices communicate with each other using wireless only......not Ethernet.
It would help if Apple used settings like "Extend a network using Ethernet" and "Extend a network using wireless only".....but they don't.
The AirPort Extreme will need to be configured as the main router if you want it to provide a Guest Network. It cannot do this if it is configured in Bridge Mode.

Someone gave me a airport express router. it works great with my macbook but when i try to connect to my iphone it says it can't be set up by "this software". Where can I download whatever software my iphone needs so I can get wifi?

Per chance is your AirPort Express Base Station (AX) an 802.11g model? If so, that is why you are getting this error message from the AirPort Utility running on the iPad. You would need to use either version 5.6 or 5.6.1 running on a Mac or a PC to administer this base station.

I am setting up a used Airport Express. It works fine with my computer for internet connection. Now I am setting it up for Tivo connection. They ask for a Gateway router number. Where can I find this number?

The "gateway" number for your AirPort Express, by default, is 10.0.1.1

I changed cable providers and now my Airport Express won't connect to the Internet. How do I fix this?

I changed to Time Warner cable. Upon doing so, my Airport Express lost its connection to the Internet. When I run the Airport Utility, I am stuck at the first step, which says the AE doesn't have any DNS server addresses. What are they and how do I find out what they should be? And if I supply them, will that fix the problem?

Have you performed a Factory Default Reset on the AirPort Express?
If not, the Express is still remembering the settings that you programmed into it when you configured it to work with your old modem.
The Express is "looking" for your old modem, but it does not "see" 'it because it is no longer there...so it can't connect to the Internet.
If you have not already tried the Factory Default Reset and you need more info about this, post back for more details.

Older model Airport Express won't work with Mountain Lion Airport Utility

just upgraded to Mountain Lion and noticed that of my network of three airport expresses connected to various stereo speaker systems throughout the house, one of the older models won't work with the supplied version of Airport Utility (v 6.1). Here is the message it gives in the utility when I attempt to select this particular Airport Express:
"This version of AirPort Utility doesn't support this base station. Use AirPort Utility 5.6 to configure or manage this base station. AirPort Utility 5.6 is available at AirPort Service and Support."
Well, I go to download v 5.6 and none of the versions available will install on Mountain Lion! (even the version for Lion) Catch 22.
Any resolution to this (other than having to go out and buy a newer version Airport Express)?

Airport Express won't work with VPN

Finally made it through the nightmare of setting up my Airport Express to act as a wireless print server on my existing network (Linksys WRT54G router). However once I log onto my corporate VPN, I cannot print or even see the Airport. I have checked the LAN access box on the Transport tab of my VPN software which is supposed to allow split tunneling, but no luck. Everything works fine once I log off the VPN. I bought the Airport Express specifically because an Apple rep told me it would work with my VPN. My previous wireless print server (Linksys) would not support VPN.
Appreciate any help!

Airport express won't work with Extend Network, only Create Network

My Airport Express when it is setup to extend my network while plugged into Ethernet will Create a network under settings. If I change this to Extend A Network it doesn't work properly. It keeps kicking me on and off WiFi, but the former way works with no foreseen issues. What is going on? I can't extend my guest network with the first option, I don't believe.
I have a 5th Generation AirPort Extreme and a 1st Gen AirPort Express.

Airport Express won't work with Acer Aspire One

I've recently set-up a wifi network for my parents. They have a cable modem from which an ethernet cable runs to their Vonage modem. From there, another ethernet runs to the Airport Express (set to Bridge Mode). Wifi uses WPA2 Personal encryption.
My MacBook Pro as well as my dad's Dell laptop (Vista) can connect just fine and browse the web, no problemo.
However, my Mom's Acer Aspire One netbook (Win XP) keeps on saying "Acquiring network address" and kind of just hangs there. I've tried resetting the Airport Express to no avail. Does anyone have any ideas what could be causing this? I'm open to any suggestion guys, thanks!

I'll take a quick pass, but no guarantees as I'm not a PC guy.
XP, depending on the version installed on the Acer may not fully support WPA2 Encryption. Or, if it does, you may need to change some settings on the PC to use TKIP, not AES associated with WPA2.
It might be a bit easier to switch the security to WPA/WPA2 Personal on the AirPort Express and give that a try.
AirPort Utility > Manual Setup > Wireless Tab > Wireless Security.
The same TKIP/AES thing may still apply on the ACER though, so you'll need to investigate if things are still sticky on the ACER.
Finally, my PC friends tell me that 90% of all connection problems on a PC can be traced to the Firewall settings and/or anti-virus settings. You may have to go into the applications to specifically allow the connection to the Express.

Airport Express Won't work on Computers but works on other devices

I switched from att dsl to comcast internet. I set up my modem and then purchased an airport express to use as my wireless router. When I set up my airport express, I installed the airport utility on my windows vista laptop, was able to create a network, password, etc.. However, once set up, I could no longer find my airport express in my airport utility. My windows vista laptop, and windows 7 laptop can not connect to the internet. I also installed airport utility on the windows 7 laptop and that laptop cannot locate the airport express. However, my PS3, Wii, iPhones, and old XP desktop can all locate the network, connect and work very well.
Also, if I directly connect the ethernet cable into either laptop, they will connect to the internet fine. I have tried downloading drivers, changing security on both, resetting the airport, power cycling, and have not succeeded. I have no idea what to do next. I can not understand why most of my devices can detect the router and others can not. I know that the laptops can connect wirelessly because I brought them to my parents house to test them out and they both worked fine.

Hello akommatas. Welcome to the Apple Discussions!
Please try temporarily disabling the Windows or third-party software firewall on any PC that is having difficulties accessing the AirPort Express Base Station (AX) with the AirPort Utility. Can the utility find and access the AX now?
If not, instead of waiting for the AirPort Utility to scan, go to the utility's menu bar, and then, choose File > Configure Other ... > Enter 10.0.1.1 in the IP Address field, and then, enter public for the password.

Aiport Extreme and Airport Express are not working together with DSL

My 2wire modem failed and I have replaced it with a basic actiontec dsl modem. I have my airport extreme connected to the actiontec via ethenet cable. All is working. Internet access through the actiontec is working and internet access through the extreme is working. What I cannot for the life of me remember how to do is get my express to work as a range extender for airport extreme.
The extreme is set up in Ethernet not PPPoE mode which might be the issue, but I can't remember the right settings (IP ranges, etc) if I set it up in PPPoE mode.
Net - my network that was working DSL modem to Extreme to Express as a range extender no longer works at the Express end. And don't even get me started about AT&T tech support. Help smart guys/girls out there - I know this is something simple that I should have written down when I first set up my network...

Good People,
I have an Airport Extreme serving as my wireless router with an external hard drive connected to it. I also have an Airport Express in another room connected to a stereo for Airplay. Neither can be found on the Airport Utility (v5.5.3), but wireless internet still works. This happens often, with both reappearing in Airport Utility for short amounts of time periodically.
I've once had the same problem.
The reason for that issue is the frequency (radio band) hopping of the station.
On your AP-Extreme
Enter the manual setup
Disable Guest Network if not desperately needed
Set a dedicated name for the 5GHz wireless (wireless -> wireless options)
Eventually change the radio mode (if no 802.11b/g systems in your home) to "only 802.11n (5GHz) - only 802.11n (2.4GHz)" by holding down the option key *alt* while clicking on the drop down.
On your Mac
Disable (switch off) wireless
Enter system configuration -> network -> wireless
Uncheck "Ask to join new networks"
Enter advanced options and check that your wireless name is in the first position of the list. If not, drag it with the mouse to the first position.
Click apply
Join your wireless again and try to connect to the 5GHz name (SSID) because the 5GHz will improve the connection speed of your Mac remarkably.
Eventually you might change the settings on the Express too.
Check the location of the AP-Extreme.
It should NOT be placed: On the floor, in a corner, behind furniture, near metal objects, life high voltage wire or cordless phone bases.
It should be placed: As high as possible (up on a shelf or ceiling mounted) with a maximum line of sight to all stations, even thru walls.
If your home situation allows that, try to use the 5GHz band only. If you own a iPhone this must use the 2.4GHz radio.

Second Airport Express won't work

I'll explain my current set up first, then explain my problem. I have an iBook G4 running 10.4 with the latest version of Airport Utility. I have a BT Home Hub as my main wireless router, to that I have an Airport Express connected via an ethernet cable. To the AE I have a stereo lead connected to my amplifier. I use airtunes from my iBook to play music via the AE. I also connect the iBook to the internet via the AE unit (rather than through my BT Home hub as it's faster that way!).
Ok my question/problem:
I have a amp/speakers in my kitchen. Also the wi-fi signal in the kitchen is poor. On mentioning this to my Dad he mentioned he has a spare AE unit, why not plug it in and extend the range of my original wi-fi signal and connect my second amp/speaker set up that sits in the kitchen. We are both working to the assumption that when a second AE is connected to the network, you can simply go to iTunes, select the drop down menu in the bottom right hand corner (the "select which speakers" and I choose "Kitchen" instead of my current "Living Room" AE.
Now I've spent so may hours trying to make this scenario work, checking the usual sites but it just doesn't seem to work. My wife may divorce me if I spend much more time on this! Save my marriage and help me listen to my beloved music in the kitchen.
Can this be done?! It's driving me crazy!!

Sorry guys I'm totally lost now.
The two units are clearly not at the same firmware level, one being older than the other.
I can't find a selection anywhere for "extend a wireless network" on AX2
I've also tried to configure the 1st AX to act as a WDS main base station. The 2nd AX should be configured to act as a WDS remote base station and I get the error message:
"AIRPORT UTILITY WAS UNABLE TO FIND YOUR APPLE WIRELESS DEVICE AFTER RESTARTING.
The settings for this apple device have been successfully updated, but there was a problem re-joining the wireless network or finding the Apple wireless device. You may need to select your network again from the Airport menu and try again"
Which I can't do as AX2 disappears and I can't see it in the toolbar, or see it when I scan for it in Airport Utility and I can't see it in iTunes it just sits there flashing orange in the Kitchen as an expensive, useless bit of plastic.
Help.

Airport Express won't work unless it's behind a router...

After experimenting with my airport express to try and get it to work with some game of mine, I discovered that my airport doesn't get an internet signal unless the connection from the modem to the base station goes through a router.
This is really strange... does anyone know anyway to fix this?
By the way, yes, all my cables work, I use SBC Yahoo DSL as my ISP, I have a speedstream modem, and my connection apparently has to go through an Asante router, although it may work through other ones.

OK,
Is the IP address of the form 192.168.x.x, or 10.x.x.x, or something else ? This will help us identify if the ISP is allocating you an IP address dynamically, or maybe you have to key it (just once) because they've allocated you a static IP address.
The DNS server addresses present but greyed out is what I hoped to see. I had hoped Router address would be set (and greyed out), this is where all your internet traffic gets sent to. I'm also a bit puzzled at the Subnet mask not being 255.255.255.255, which would be the normal value for ISPs to set on customers connections.
If you plug your mac (if possible) straight into the ethernet cable that comes out of the modem, put the Network system preference on Automatic, and then check the Built-in Ethernet in the same system preference, what does it show ? same values as appeared in the Airport config ? This is just to rule out any other factors.
I'm sure the answer we need is in the configuration of your (nearly redundant) router. It will have settings, either already set, or allocated by the ISP that we need to mirror in the Airport. If you're comfortable in the router configuration, print (or screen dump) all the details, then we know what works and can begin to configure the Airport in a similar fashion.

2nd airport express won't work

I have an airport extreme base station and 2 airport expresses. The first express is necessary to extend the range for our wireless in the house. I can't get the second express to work with itunes since I started using the first express to extend range.
I have configured it and my computer sees it but it doesn't stop flashing amber and itunes tries to connect but is unable.
The guy at the apple store told me that it IS possible but I must be doing something wrong.
Thanks for any help.

Hard reset the second Airport Express and reconfigure it to join your existing network in client mode.
