Trouble setting up 2nd mac with my Airport Express

I just got the Airport Express (802.11n) on the weekend and finally (after an hour or so) got my imac G5 to get hooked up to it. It wasn't easy and although I used the Airport Express utility, it was a bugger to set up for some reason.
I also have a G4 Powerbook that my wife uses. When I originally set up our Airport Express on the weekend, both of our computers found the network and connected no problem. Yesterday, there was a problem with our ISP (Rogers here in Toronto), so I reset everything back to the factory settings on the Airport Express and did our network all over again. My computer can connect again to our network but when I checked her computer, it sees the our network name but can't connect to it. Her computer, however, can connect to the unsecured wireless network our neighbour has lol, so we know everything is good with her airport card.
I'm wondering what I did wrong here. I think it has something to do with the settings I'm manually putting in but here's my question:
Do I have to manually configure both computers to get onto our wireless network or should I let it happen automatically?
I don't really understand all the IPv4 settings either (or, for that matter, the DNS settings either). Do both computers have to have a IPv4 address that is one digit off one another?
If someone could dumb this all down for me, that would be perfect lol. I need to also write down all these settings when everything is up and running perfectly for both computers.
TIA,
Dale

Keep in mind that ordinarily your airport functions as a router. This means that the one IP on its WAN side (via cable) is used to serve numerous artificial IPs on its LAN side (via radio).
Outbound packets get their return-IP addresses changed by the airport on the way out. Inbound packets are a little more difficult. The automatic translation of inbound packets from one IP address on the WAN (Wide Area Network) into the correct one of several potential IPs on the LAN (Local Area Network) is done by a clever little function called NAT (for Network Address Translation), which is also built into your airport.
Normally, you let the airport assign the artificial LAN IPs. It will do this in numerical order as the respective computers in your house get recognized.
Most houses work fine with the automatic setup.
And then there are variations galore...

Trouble extending my WiFi network with older Airport Express

Hi,
As the question states, I have an older Airport Express which I have dug out to try and extend my WiFi network in a new house.
I am on Virgin Media (fibre optic) in the UK and get a good WiFi service but one room in the house (which I have just turned into a cinema/media suite) has no reception.
I have successfully managed to 'create a new network' via the Airport Express and the signal strength is 100% but for some reason if I try to reconfigure the device to extend the existing network I get no improvement at all from the (zero) signal I was receiving before.
Am I doing something wrong? Or is there an additional step I am missing?
I could live with having a secondary network but what I would really like to achieve is Home Sharing from my main computer, so that I can access my photos, movies and music etc. from iTunes on the big screen. If the computer exists on another network my iPad, iPhone and AppleTV can't see/use the media from that room.
Many thanks in advance,
Colin

Are these the steps you used?
To create a wireless extended network, you must place any extended Wi-Fi base stations within range of the primary Wi-Fi base station.
Start with the device that will be configured as the primary Wi-Fi base station. Then configure your extended Wi-Fi base stations, ensuring that each is within direct range of the primary Wi-Fi base station.The physical location of extended Wi-Fi base stations will vary according to the building environment and may require some experimentation.
If you have configured your Wi-Fi base stations in the past, it may be helpful to do a factory default reset of each Wi-Fi base station that will be part of the wireless extended network before you begin.
Configuring the primary Wi-Fi base station
Power on all 802.11n Wi-Fi base stations and allow them time to appear in the AirPort Menu Extra.
Open AirPort Utility (On a Mac, choose Go > Applications from your desktop, click the Utilities folder, then open AirPort Utility. In Microsoft Windows, choose Start > All Programs > AirPort to start AirPort Utility).
Select the primary Wi-Fi base station in the Base Station Chooser, then click Continue. Note: If you see a message appear that indicates that the Wi-Fi base station has been reset, click Cancel to continue.
Click Manual Setup. Enter the base station password if necessary.
Click AirPort in the toolbar.
Click Wireless.
Choose “Create a wireless network” from the Wireless Mode menu.
Select the “Allow this network to be extended” checkbox.
Enter a Wireless Network Name.
Optional: By default, Wireless Security is set to None so that no password will be required to join the network. We recommend you click on the Wireless Security menu, select WPA2 Personal, and create a password between 8 and 63 characters long.
From the Radio Channel Selection menu, select Automatic.
Click Update.
The next window may indicate that there are some problems. Resolve the problems, then click Update.
You are now ready to add extended Wi-Fi base stations to your network.
Configuring an extended Wi-Fi base station
Place any extended Wi-Fi base stations within range of the primary Wi-Fi base station
Ensure that all 802.11n Wi-Fi base stations are powered on and allow them time to appear in the AirPort Menu Extra
Open AirPort Utility (On a Mac, choose Go > Applications from your desktop, click the Utilities folder, then open AirPort Utility. In Microsoft Windows, choose Start > All Programs > AirPort to start AirPort Utility).
Select the Extended Wi-Fi base station in the Base Station Chooser, then click Continue. Note: If you see a message appear that indicates that the Wi-Fi base station has been reset, click Cancel to continue.
Click Manual Setup. Enter the base station password if necessary.
Click AirPort in the toolbar.
Click Wireless.
Choose “Extend a wireless network” from the Wireless Mode menu.
Choose the network you want to extend from the Network Name menu.
Enter the network and device password if necessary, then click Update.
The next window may indicate that there are some problems. Resolve the problems, then click Update.

HT5211 My HP 2355 won't show up in AirPrint? I have it plugged in via USB and set it up on my Mac mini with the airport express network. Any advice?

Unless your HP printer is an AirPrint-ready device, just connecting it to the USB port of the AirPort Express base station will not make it so.
On the other hand, connecting a non-AirPrint printer to the base station's USB port it can be shared out by the base station's print server. Please see the following Apple Support article for details.

Set up Airport Extreme with 2 Airport Express connected by CAT5??

I recently bought an Airport Extreme base station and an Airport Express. My plan was to use to Airtunes with my AV receiver in my basement. Unfortunately, because the distance between these two areas is long (and separated by two floors) I'm not able to get a strong enough signal with the Airport Express to use Airtunes. I bought another Airport Express to put on the middle floor of our house but the signal in the basement was still not strong enough even with this addition.
I do have a way of connecting the middle floor of our house with the basement area by a CAT5 ethernet cable. My plan now is to connect the two Airport Express modules by their ethernet ports with this cable. The Airport Express on the middle floor connects with the Airport Extreme base station wirelessly without any problems. My question is what is the proper setup for the 2nd Airport Express connected by ethernet in my basement.
Airport Tech support said this could be done. They recommended setting up a new wireless network with the 2nd Airport Express by "fooling" into thinking it was connected directly to the router but using the same network name with a different wireless channel as my Airport Extreme base station. This setup actually works for several hours but then the Airport Express module that is connected to the Airport Extreme blinks amber. Interestingly the 2nd Airport Express with usually remain with the green light on.
Does anyone have any suggestions for the best way to set this up regarding network configuration with the Airport Utility?
Thanks

That will work with as long as the AirPort Express (AX) is connected via Ethernet. The only other setting you need to make is to configure it to act as a bridge (not sharing a single IP address).
If this one looses connection, then something is wrong with the AX or the Ethernet connection (cable and/or connectors).

Mac Mini Server Airport Express with Server Firewall Settings

I posted this in the Server forum, but I've had no responses so far - so I'll try it here instead! Any help is appreciated...
I've got a new Mac Mini Server (mid 2010) with Snow Leopard Server v10.6 that I intend to use as a file server in the long term, and as my main computer replacing my old PC in the short term.
One of it's uses will be my iTunes server for my Airtunes network with two airport expresses.
When I disable the server firewall iTunes can connect to the airports with the check box in the 'multiple speakers' menu in iTunes. If I enable the firewall with the default settings of 'allow these ports' I cannot. I have used the Apple document on well known TCP and UDP ports to open for Apple software packages with particular attention to streaming audio / iTunes etc. Still doesn't allow the speakers to be selected in the 'multiple speakers' check box.
I also tried the 'allow all traffic' option for the firewall, again no connection to the remote speakers happened. If I turn off the firewall it all works fine. It seems that there are some ports that need to be open in order to establish the connection - I just don't know what they are.
Does anyone know of the appropriate ports to open? I tried searching the forums and I did try some of the suggestions for port 5000, 6000, 6001 etc but it doesn't make any difference!
Thanks in advance...

I found this works too. Though I came about this a slightly different way.
I moved over to Airfoil as Airtunes didn't work without the firewall and Airfoil did. I then had problems with Airfoil not reconnecting to the remote speakers when you cycled the power on them, I don't want all of my remote speakers powered all of the time. They were set to automatically connect, yet they refused connection a couple of times before connecting, which meant logging into the mini and reconnecting manually, which wasn't what I wanted to do. During an email conversation with Rogue Amoeba I sent them a debug logfile - they pin-pointed it as a connection denial with IPv6 addressing.
Once I had that info, I disabled IPv6 for my network adaptors and Airfoil worked and reconnected fine even when airport expresses are power cycled. I then tried Airtunes again and now the speakers can be connected. It's down to the first choice for connections is IPv6, if this is not available it's IPv4.
It's definitely a bug with the IP6FW control and link-local traffic.
Hope this helps.

Setting up Time Capsule with existing AirPort Extreme 802.11n and AirPort Express.

I already have and am using an AirPort Extreme 802.11n with an AirPort Express. I want to set up a Time Capsule 802.11n. Which is the best way to configure this?

... Which is the best way to configure this?
The answer depends on what you need the TC to accomplish. If all you need it to do is perform Time Machine backups, simply have it join your existing network in client mode. It would be if it were to connect to your existing router (presumably your Extreme), not through an "extended" wireless network (presumably your Express).
If you need the TC to "extend" your network so as to serve additional wireless clients, you can do that also. Configure it to "extend" the network created by your Extreme.
As you can see it's quite versatile.

You will need to enable file sharing in System Preferences
as well as setting up sharing and permissions for the
directories that you want shared. You may also want to
setup a non-administrative user or allow limited guest
access. The user would require entering a user name and
password to make the connection, but would allow remotes
to change files, if set up tat way.
As for serving iTunes media, better to post in the iTunes forum.

When our iPad is in use on the internet, my iMac internet connection goes off. I can't get the two devices to work at the same time with the AirPort Express. Is there a setting somewhere I may have missed?

When two or more devices conflict it typically means that the DHCP service is either misconfigured or is not running at all. DHCP provides IP addresses to local network clients.
Is your AirPort Express base station the only router in your current network configuration? That is, is it connected directly to an Internet modem and not to another router upstream of it?

Yes, it is one of the things AirPort Express was specifically designed for.

Losing wireless connection with my airport express with my powerbook G4

Lately I've been losing my wireless signal from my powerbook G4 to my airport express. The light on my airport express still shows as green, so I was wondering if the trouble lied in wither the airport express or my mac? I'm running on the 6.2 version that mac had offered as an update for the express.
The signal returns if I shut down my mac, and then turn it back on, as well as unplugging the airport express and replugging it in as well. This is starting to occur now once a day at least.
I keep my powerbook in the same room as the airport express, and it is usually in fact sitting on my desk above it...so range isn't really an issue.
This is getting tedious, and would like to know how to nip this in the bud.
Please be detailed in your responses. I'm not to tech savey. Thanks.

I am also experiencing the same problem, also only since recently updating my AE firmware. I will provide a bit more information so that maybe someone will be able to offer some suggestions.
I have one AE connected to a BT Broadband modem. My iMac is down the hall, connected to the AE for internet and for Airtunes. What I experience is that I will lose connectivity to the airport itself. In fact, sometimes I can actually watch as my airport signal indicator in my menu bar jumps up and down repeatedly (although sometimes the airport signal just disappears altogether and then when I go looking for it in my Airport menubar, my network is no longer listed). The green light on my AE always stays constant when this happens (even when the airport signal goes away completely). The BT modem seems to be fine.
AE basestation firmware is V6.3.
I am connected to my AE using WPA Personal (anyone know what the Group Key Timeout option does? Mine is set at 60 minutes by default... no idea if that is connected to my issue, but I didn't want to play with it since I don't know what it does).
Channel: Automatic, Closed Network. Access Control is enabled so that only my iMac can access the network. Airtunes is enabled.
Under wireless options, multicast rate is 1, interference robustness is not enabled, and transmitter power is 100%.
Anyone have any ideas about what the problem is and what I can do to try and fix it?
Thanks.

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"

How do I set up wireless printing to my Airport Express?

I run my 17" MBP through a DLink wireless router which is located next to my modem in my basement. I have an Airport Express station (not the Base or the Extreme) which I used to use for wireless iTunes serving to my stereo, but which I now wish to use as a wireless print server in my study upstairs. I am not, however, using the Airport Express station for internet.
I can't find any useful instructions or step-by-step guides to set up a printer on my Airport Express. Can anybody point out how to do this and/or refer me to the appropriate KB article?
Many thanks,
Dustin LindenSmith

Yes but they don't seem to be making it to the post to be deleted Punctuation seems to be a possible cause
If your goal is to use one network with the AE and your other router online the AE needs to be connected to the modem as the base station as the AE can only be a wireless bridge with an Airport Extreme or connect the AE via ethernet from your other router
The printing is usually as easy as plugging in the printer and selecting it from your printer list AE is a print server and I use a 4 port hub with 4 printers connected They used to be listed as Rendezvous printers but lately mine are just showing as a connected printer but is printing wirelessly
Finder > Applications >Utilities > Airport Setup and Airport Admin utilities are pretty straight forward for setting up the routers. I have had and there are still issues being reported with the AE and certain configurations. My first gen MBP1.1 could see it but not connect and my MBP2.2 connected immediately and settings on both machines were the same.

How do I share a 3G USB modem connected to my Macbook Pro with my Airport Express?

Hi. I have a 3g USB modem connected to my macbook pro, and I want to try share the signal with my Airport Express (latest model).
Now before everybody screams that it can't be done, I was searching the forums and found a discussion in which someone describes how to do it from 2008, unfortunately it is archived and I couldn't ask the author directly, and the description doesn't go into much detail.
In the thread, the author describes turning internet sharing on to share the USB modem, creating a network on the macbook, then renaming the Airport Express network name the same as the macbook, and setting the AX to Join a Network.
Problem being there is no description of whether the macbook connected to the AX via ethernet or wifi, what settings were changed on the AX eg bridge mode.
Is this possible in theory, and has anybody had any success sharing a 3g USB modem via a macbook pro to an AX? I know there are other options like getting 3g ethernet modems, unfortunately not an option in this case - new house, waiting for DSL to be installed, 2-3 month wait.
Thanks

Well, you cannot use the 3G USB modem plugged directly into the Express. However, you can configure your MacBook Pro to do 'Internet sharing' (SysPrefs>Sharing) over the Ethernet port, and then connect your Express into the Ethernet port. Alternatively, you could always get your MacBook to 'create a wireless network'.

You could always look for open WiFi networks to *cough*borrow*cough* .

I am unable to join my existing wireless network with new AirPort Express

I am unable to join my existing wireless network with new AirPort Express.
I am using a DLink DI-524 Router, Windows 7 (64), and the AirPort Express.
AirPort Utility will not recognize the AEX wirelessly, it will only recognize it when it is connected by Ethernet. I can then configure the AEX and verify that the settings stick once disconnected and then reconnected. However, even after that, it will not recognize the AEX once disconnected from the Ethernet cable.
I followed the suggestions of several other threads on these forums. But I am unable to get the AEX to work.
Any suggestions? Thanks in advance.

Welcome to the discussion area!
It's almost always a security setting that causes problems when the Airport Express (AX) tries to join a third party wireless network. The AX usually does not "join" correctly and that's why you can't see it on your wireless network using AirPort Utility.
Using an ethernet cable is still the more reliable way to configure and adjust the AX, but if you are want to try to configure it using wireless, you must return the AX back to factory defaults as follows:
Power down the AX
Hold in the reset button +and keep holding it in+ as you plug the AX back in to power
Release the reset button after 10 seconds
When it is set to factory defaults, the AX broadcasts a wireless signal with a network name like "apple network xxxxxx" where the "x's" are either letters or numbers. You must look for this network by clicking on the fan shaped Airport icon at the top of the screen. If you don't see this network, then click Join Other Network to search that way. Unless you connect to this network, you will not be able to configure the AX using wireless.
Do you know the exact security type that your D-Link router is using? That is the key element in the process.
Open AirPort utility, click Manual Setup
Click the Base Station tab to establish a name for the AX, device password and adjust time zone settings
Click the Wireless tab
Wireless Mode....Join a wireless network
Wireless Network Name...must exactly match your D-Link wireless network name
Enable ethernet clients if you want the port to be active (your D-Link must be compatible with ProxySTA for this to work)
Wireless Security...exact setting of the D-Link network. WEP security causes a lot of issues. Try to use WPA/WPA2 Personal, which is far more secure.
Wireless Password...must match the D-Link network
Click the Music icon to enable AirTunes
Click Update to save settings
Any luck?
