Airport Express as "Ethernet-Bridge" for old iMac - how to configure WPA?

Hi,
I have a very old iMac G4, which up to now was connected to my network via a Netgear wireless bridge. As I switched my router to a Fritzbox, which supports N-Draft I wanted all network clients to use N-Draft, so I bought the new AX.
It works ok as an Ethernet bridge when configuring the wireless part to "connect to a wireless network", "allow ethernet clients" and no encryption.
I am now online with that configuration.
But when I activate either WEP, WAP, WAP&WAP2 encryption on my Fritzbox router and then in the Airport Express it won't get an IP-address via DHCP anymore. It can connect to the wireless network, but via the ethernet connection it does not assign ip-address anymore.
I already tried assigning the IP-address manually. The light on the AX is green, but DNS does not resolve, although I also entered the DNS server of my provider manually.
Any idea? Is it perhaps just not possible the use the ethernet port if the wireless connection is encryted?
Regards,
Jörg

Hi again,
I can answer my question now: my router (Fritzbox) and the Airport Express can only communicate with ONE kind of encrytion - only via WAP2.
WEP does not work, WAP does not work, WAP/WAP2 does not work.
But at least now I have a complete N-Draft Network with good encrytion. It only cost me 4 evenings of long trial & error configurations.
Hope I can at least help others,
Jörg

Using Airport Express as Ethernet Access for Network Audio Receiver

Hello,
I have a quick question.
I recently bought a Onkyo CR-N755 Network receiver.
I would like to take advantage of the network radio functions, but am running into a problem.
I created an "Internet Sharing" set-up so that my macMini shared it's wi-fi signal over Ethernet, but it seems that this creates a new network as the receiver shows that it has IP address 192.168.2.3, where as everything else in the house is on 192.168.1.xxx. The receiver was able to access internet radio, but I could not find it with the controller app on my iphone, presumably because it was on a different network.
I think that the easiest solution would be to buy an Airport express and Connect the receiver to it by LAN.
In order to do this, would I set up the express as a bridge, create a new network with the same settings as the Extreme, or would I have to extend the network? I have read that bridging reduces bandwidth, so I would prefer not to do that if possible.
So can (and how do) I go...
Airport Extreme --wireless-- Airport Express --Ethernet-- CR-N755 while still keeping full bandwidt for the 3 ipads, 2 iphones, 2 wifi macs, appleTV, and numerous connected gaming systems that I, my wife, and 3 children use?
Thanks for any help you can offer.

In order to do this, would I set up the express as a bridge, create a new network with the same settings as the Extreme,
This option would require a permanent wired Ethernet connection between the AirPort Extreme and AirPort Express. This will provide full bandwidth over the entire network.
or would I have to extend the network
This setting would be used if you plan to connect the AirPort Express to the AirPort Extreme wirelessly. There will be some unavoidable loss of bandwidth over the network with this type of setup.....approximately 30-50%, depending on a number of factors.

Airport Express as a bridge for a Panasonic BD35 Blue Ray Player

Just put in Crank 2 and it will not play, discovered this problem is due to the coding on the BR disc that is looking for an internet connection and if one is not available the disc plays in a distorted mode.
I have connected an ethernet cable from my co-located Airport Express (that is hooked into the stereo to play streaming audio from laptop) to the Panasonic BD35. On the BD35 network set up I can not get it to hook up.....the connection test fails every time.
Any one have any experience with Panasonic issues of connectivity? My issue is with getting the BD35 to recognize the internet hook-up. Thank you for your time....

Welcome to the discussions!
Can you turn off the wireless temporarily on a laptop and plug into the AirPort Express to see if you can get an internet connection?
If you have a newer AirPort Express"n" and "enabled ethernet clients" during setup, you should connect.
If your AirPort Express is 2+ years old, you will not have the ethernet functionality on the older "b/g" Express. What main router are you using?

Airport Express as ethernet - Airport bridge

I just bought an Express thinking it would be easy to configure to bridge my existing DSL -> wifi connection to a new wireless LAN.
Before I open the box I would like to know for sure that this will work. If the Express can't do this, I'll order a LinkSys WET54G bridge.
Our internet connection is via Airport as we live on our yacht. Our G4 connects to the net via a 24db antenna to the marina wifi network. The G4 is configured w/ Internet Sharing ON.
Our iBook connects to the net OK over ethernet via the G4 sharing. Now I'm trying to create a local wifi LAN on the boat so we can avoid CAT-5 strung around the boat.
Is the Airport Express the right solution?
Any suggestions mucho appreciated!
Steve

iFelix wrote "You can connect an Airport Express to the G4's ethernet port and configure to not distribute IP addresses and this will work."
Thanks heaps - got that. Will the wireless client[s] receive their IP addresses from the G4 DHCP server [Internet Sharing]?
I ask because all the Apple docs I've seen on configuring Extreme or Express as a bridge say that "all AirPort and Ethernet computers need to have IP addresses set manually and use the same subnet mask."
E.g., In Designing Airport Networks, p48,
Using the AirPort Extreme Base Station or AirPort Express as a Bridge
You can turn off the base station’s Internet sharing features (which provide IP addresses to AirPort computers using DHCP or NAT) to allow bridging between the network’s wireless and wired computers. With bridging turned on, AirPort computers have access to all services on the Ethernet network, and the base station does not provide Internet sharing services. Using the base station as a bridge can be a way to address incompatibilities between the base station’s Internet sharing features and your ISP’s connection method. To use the base station as a bridge, all AirPort and Ethernet computers need to have IP addresses set manually and use the same subnet mask.

Hello 84wvu,
It sounds like you want to setup your Airport Express to Airplay music from iTunes. I found an article with steps to help you get this setup:
Connecting to an existing Wi-Fi network, exclusively for iTunes music
AirPort Express used exclusively for AirPlay by setting it up in Client Mode.
Choose this configuration if the computer containing your iTunes library may be out of direct range of the AirPort Express, but is within range of the Wi-Fi network.
How to Set It Up
Connect your AirPort Express to your home stereo or powered speakers.
From your computer, join the wireless network. Use the AirPort status menu in the menu bar on a Mac. On a Windows-based computer, hold the pointer over the wireless connection icon until you see your AirPort network name (SSID), and choose it from the list if there are multiple networks available. Enter the network password, if necessary.
Open iTunes on your computer and choose the AirPort Express(es) you wish to stream music through from the speakers pop-up menu in the lower-right corner of the iTunes window.
I also recommend reviewing the sections titled "Some things you should know about AirPort Express with AirPlay" and "Things to consider before you begin" in the full article:

Connecting to Airport Express via Ethernet Cable

Dear Apple Support Community,
My setup at home is such that all my devices are in such close proximity to the Airport Express, and therefore I connect everything to the Airport Express via ethernet cables (NAS, Apple TV, PS 3).
The final step in my network setup would be to connect my Macbook to the Airport Express to connect to the internet using the Ethernet Cables, instead of using the wireless connection - because my Macbook is positioned right next to the Airport Express.
However, I am struggling to get the Macbook to connect to the Internet via the Ethernet Cable through the airport express. Is there a special way to set this up if this can be done. I know Wireless would be the answer, but the problem is, when I download movies etc, I write the files directly onto the NAS which happens a lot quicker than doing so via WiFi.
I hope the above question makes sense.
Thanks in advance for any feedback.
Regards
ST

Hello Brian Hunt1. Welcome to the Apple Discussions!
I have an old PowerBook G3 and I do not have a wireless card for it. My plan was to connect it, via Ethernet cable to my airport express which is on my home wireless network (DSL to Mac Mini to AirPort Express via built-in AirPort).
Unfortunately, the network configuration your describing, where you would use OS X's Internet Sharing feature to share the Mac Mini's wired Internet connection wirelessly with the AirPort Express Base Station (AX), won't work.
If I cannot connect my laptop this way, could anyone suggest a wireless card that is compatible with this slightly antiquated, yet very useful machine?
Only the "Pismo" PowerBook G3 is capable of using the original AirPort card. If you have this model, then the following DIY instructions will show you how to install it.
If this isn't your model, then check out the following vendor offerings:
o QuickerTek
o hField Technologies' Wi-Fire

Connecting Two Airport Express Via Ethernet

I have a unique situation in which I would like to connect two airport express via ethernet. Here is the situation: I can connect the first AX directly to the internet and set up a WDS for the second AX. Unfortunately, the second AX signal does not reach where I need it to go. I can run an ethernet cable between the two. Is this setting valid for a WDS? Or does the WDS have to be wireless? If I can set up the WDS using an ethernet, will the relay AX broadcast the internet wirelessly then?
Are there any specific settings I should know about?
Any help would be great.
Thanks in advance,
Debbie

I currently have an old snow basestation at this location. Can I plug an ethernet cable into it and connect it to the AX?
Yes that will work.
My understanding was that the older basestation could not do this?
I think you have it confused with extending a network wirelessly. That is not possible with the snow AirPort base station (ABS).

Time Capsule & Airport Express as a bridge

I am using a Time Capsule as my wireless router upstairs, and I would like to set up an Airport Express as a bridge so that I can connect my Xbox 360 to my network (to play Xbox Live and stream Netflix and iTunes, etc.). Do I have to do something to the Time Capsule to get this to work? Or can I just use a laptop downstairs (where the Xbox is) to configure the Airport Express as a bridge? I looked in the manual settings of the Time Capsule but all I see is for it to extend a network, not to allow anything else to extend the network it's already creating.

+In the Airport Utility they are both configured to "Join a wireless network" and have checked the box to "Allow Ethernet clients". Very stable connection.+
Not sure if you were aware that you have the option to configure the AXs to "extend a wireless network" as well. The ethernet port is also active in the "extend" configuration. If you need more wireless coverage, this is a nice feature of the AX(n).
Then again, if you don't need the additional wireless coverage and things are working well as you indicate, you might want to just leave things alone.

Using Airport Express as internet connection for one Mac and one PC

Will probably be judged a complete dork for this question. I have successfully set up my Imac G5 to run an internet connection through an Airport express. My partner runs a PC (Windows XP) and I want to connect this too. Have installed a USB wireless card on the PC, and installed Airport Utility, but it just won't find the Airport Express - it will however find the Imac with something like 96% signal strength. So I set up a network on the Mac and have successfully linked into it with the PC, but it soon comes up with a connectivity problem that will not allow internet browsing. So two questions - can I connect two computers to the Airport Express at once for internet browsing, or do I have to do it through linking the PC to a wireless network? If the latter is the route - any ideas on what the connectivity issue will be? Help!

No, not if the AirPort Express "joins" the wireless network.
No, I do not want to join a network.
It is possible to have the AirPort Express "create" a separate wireless network that would not have access to the Internet, but if you did this, you would need to log off of your normal network....(losing your Internet connection) and then log onto the AirPort Express network when you wanted to listen to AirPlay.
Then, when you wanted to have Internet access, you would have to log off of the AirPort Express network and log back onto your normal wireless network.
Ok, I understand that it is not possible to use airport express only for sound streaming while having an Internet connection at the same time. Airport express does need to join a network if I want sound streaming next an Internet connection. I wanted airport express not to get into way of my Internet connection because in this case the sound streaming messes up sometimes. When I configure airport express only as a sound output, the problems I encounter fade away but then I cannot access to the Internet. Anyhow thanks a lot for the answer.

Question re AEBS Connected to Airport Express via Ethernet

If I have an AEBS that is being used to extend the range of my wireless network, if I connect an Airport Express via Ethernet to this AEBS for purposes of itunes airtunes will this work and will the wireless network remain wireless-n?

Yes, it will.
You also have the option of (a) completely turning off the radio on the Airport Express or (b) leaving it on, and using it to create a b/g point of access to your LAN thus allowing you to run the AEBSn in n-only mode for your n-capable wireless clients.

Airport Express as wifi card for Xbox Live, then connect to Extreme network

My son just got xbox Live and we're trying to use Airport Express as wifi card for xbox (connected to xbox via ethernet). We use Airport Extreme as router for the house.
We're having trouble setting up Xbox Live, keep getting stuck at getting the xbox to communicate/access the web. Error reads "can't obtain IP address from router... make sure DHCP is enabled and has a large enough address range for all devices on network.. also make sure MAC filtering allows your console's MAC address or is disabled... "
We dont' know what else to do. I'm at wit's end before giving Gates $100... Anyone know how to get connected?
Thank you!

You can also perform a simple test to verify if you have an internet connection at the ethernet port on the AirPort Express.
Move a laptop near the Express, turn off the wireless on the laptop, and connect to the Express using an ethernet cable. See if you can open your browser and get a good solid internet connection.
If you can, the Express is setup correctly and you know that you have an internet connection reaching all the way to the Xbox.
If you can't then there is a configuration error somewhere and it will need to be identified and corrected.

Connecting aiport extreme and airport express via ethernet cable ?

Is it possible to connect an airport extreme to an airport express via ethernet cable, I ask because I want to expand the range of my wifi network to the basement of my house, the floors are really thick concrete so I installed some ethernet cable runs, I hope somebody can help me, thank you.

+How do I do it ? Do I connect the modem to the airport extreme and then run the ethernet cable from one of the extreme's ethernet ports to the express ethernet on the basememt and a second cable from another of the extreme's ethernet connectors to the express on the second floor+
Yes, this is exactly correct.
To configure each AirPort Express (AX)
Open AirPort Utility, click Manual Setup
Click the Base Station tab below the icons to name your device, assign a device password and adjust time zone settings. Give each Express a separate name so you can identify then easily.
Click the Wireless tab
Wireless Mode...Create a Wireless Network
Wireless Network Name...Exact same name as your AirPort Extreme network
Radio Mode 802.11n (802.11b/g compatible) if you want to use 2.4 GHz
Channel...Automatic
Wireless Security...Exact same setting as your AirPort Extreme network
Wireless Password....Exact same setting as your AirPort Extreme network
Click the Internet icon
Change the Connection Sharing setting at the bottom to "Off (Bridge Mode)"
Click Update at the lower right and the AirPort Express will restart in 20-30 seconds
I think it is easier to configure each AirPort Express with AirPort Utility by temporarily connecting it to your computer with a short ethernet cable. Once you have saved the configuration, you can move the Express to the location that you need.
Please post back on your progress.

AirPort Express over Ethernet lost the connection

I have an AirPort Express device. It's works well, if I connect it over WLAN. If I connect the AirPort Express over Ethernet via cable, then after about 15 minutes, I lost the connection between my PC and the AirPort Express.
Does I have to change settings in my router?

then when I try to switch it to extending
That is not the correct setting to use.
"Extending" is only used when an AirPort connects using a wireless connection to another AirPort router.
When the AirPort connects using Ethernet, you have to use the "Create a wireless network" setting.
It might be a lot easier if you simply start all over again and let the configuration "wizard" do most of the work for you. All that you really have to do is name the network, name the Express, enter the password and click Next. Everything else is handled by the configuration utility.
Post back if you are not sure how to do this.

I'm getting poor performance from my apple TV, will plugging in my airport express via ethernet to apple tv increase its performance (poor wi-fi signal)

Yes, though it is less ideal than what I suggested earlier. You would need to place your AirPort Express in a location approximately midway between your AirPort Extreme Base Station and the TV. Then, using AirPort Utility, configure it to "extend a wireless network".
It may help. Bear in mind the signal thus "extended" by the Express can only be as good as the signal it can receive from the Extreme. That is the reason for selecting its appoximate midway location.
Read about it here: http://support.apple.com/kb/HT4145
Scroll down to "Wirelessly Extended Network (802.11n)" for a picture.
This solution requires an all-Apple wireless network. No third party stuff.
You mentioned using Ethernet. That would be a better idea. Scroll down to "Roaming Network (Ethernet-connected Wi-Fi base stations)" for a picture. In your case, the longer the Ethernet cable - hence the closer you can move the Express to the TV - the better
