Use Airport Express as ethernet to wireless bridge Network
As far as I know this is an undocumented feature of the Airport Express. When set up to extend an existing wireless network, Airport Express becomes a ethernet to wireless bridge, with a dhcp server running on the ethernet port. This is a great way to connect any computer that has ethernet, but no wireless capability to your wireless network.

I found this out when I got frustrated waiting for an Airport Adapter on backorder for one of my old indigo slotloading iMacs. The Extreme costs ~$20 more than an 802.11b Airport card + adapter, but is available today, not weeks from now... and also extends my wireless coverage to my whole house including front and back yards!

Use Airport Express as ethernet to wireless bridge
Authored by: jbouklas on Oct 01, '04 12:23:25PM

I bought an Airport Extreme and Airport Express. The Extreme is used to share the Internet connection, and the Express is for bridging the connection to an ethernet port on my old G4, as it's very hard to find the original airport card for under $120. I couldn't get it to act like a straight bridge until I used the Wireless Distribution System feature. Once I did that, it bridges my ethernet connection and allows the Extreme to assign IP addresses. It also extends my wireless coverage seamlessly throughout my entire house, which is awesome. It was a bit pricey (about $300 for the setup), but well worth it.

what kind of throughput are people getting using this situation? I only get about 1 megabit/sec when transferring files to the bridged computer, which is way toooo sllloooowwwwww! any ideas on how to increase the speed?

How did you config the AP Express. I remember reading an Apple KB article stating that this was not possible. (or at least not supported)

That explains why my searches on AE didn't turn this up. Thanks!

I forgot to say that my iMac wouldn't load the AE Setup Assistant software - because it didn't have an Airport installed. Luckily I have an airport enabled tibook, and was able to use that to configure one AE as a base station using WDS and the second one to extend that network.

I want to extend my wireless range, but I'm using a Netgear router. Does anyone know if the Airport Express will extend a wireless network for devices other than Apple's?

From their web site:

3. AirPort Express can extend the range only of an AirPort Express wireless network.

If your non-Apple router is 802.11g and supports WDS, it's possible that it would work. I replaced my $15 D-Link router with an AirPort Extreme/Express combo so I could do this.

Also, I really thought bridging to a wired network was advertised, because I bought my Express the day it was announced with that exact purpose in mind. I don't see it explicitly mentioned on the web site now, but I'm sure it's in the manual.

Netgear does not support Apple's WDS protocol. You can use an Airport Express to extend a wireless network by joining the Netgear router, but it will not join as a WDS remote station and thus disables the ethernet port on the Express. Wireless connections is all it will support.

I have spent the last week trying to get the network that I expected using a Netgear 814v2 802.11b router and an Airport Express. My intent was to have Airtunes and an XBOX connected at the other end of the house. While the wireless network worked the XBOX could not join. It took a second Airport Express connected to the Netgear router to create a wireless sub-network that allowed me to create a WDS that the XBOX could join.

As it would happen an open-box airport extreme came up at a to-good-to-pass-up price. Now with the Netgear, Extreme, and two Express' I have wireless everywhere in the house, Airtunes upstairs/downstairs/outside/ XBOX online, mobile ethernet ports for my old Wallstreet PB and my wife's Dell, and BASE100 ethernet for the two main stationary computers for large file transfers. While more than I set out to spend it has added a lot of connectivity possibilities.

And the cool part, using multiple accounts or multiple computers you can stream Airtunes to each of the basestations at the same time with Nicecast. If you can stand the difference in songs or synchronization you can do it just using I tunes and different accounts.

Ciao, Mark

Thanks for the detailed info.

So, are you saying I would need to buy 2 Airport Expresses, one to attach to my Netgear 814v1 router, and the other to go downstairs near where I want the network to extend? And that the Ethernet port on the remote Express would be disabled?

But the benefit is that I'd have greater wireless range. Mainly I want my G4 PowerBook with built-in wireless to be able to connect to the network more reliably, so that need would be satisfied. It would have been better to have the Ethernet port available too...

Authored by: Loren on Oct 01, '04 02:37:32PM

I went to my local Apple Store and asked the Genius bar if I could use the Express this way. They said No. The express would extend a network wirelessly, but when it did so, the it wouldn't give access to a machine plugged into the Ethernet port. That didn't make any sense to me, so I chose not to believe him and to try it myself (for my ReplayTV).

It worked like a charm.

Phenomenal little devices.

I have an Airport Express set up in this manner, but didn't realize that it isn't documented. (I have a bad habit of neglecting user manuals.) The only hitch is that the AX must be configured wirelessly (it can't be set-up using the ethernet port).

This is simply not true.

I have an express, also set up as an Ethernet bridge so that wireless devices are on the same subnet as my wired devices. I configured it completely over the wire.

On my machine the Airport express Setup Assistant software wouldn't install on an non-Airport enabled computer. Not saying you can't configure it from the ethernet port, just that you can't load the assistant to a wire-only machine.

Use Airport Express as ethernet to wireless bridge
Authored by: covvie on Oct 02, '04 04:42:25PM

Note that it will NOT behave as a standalone bridge like a WET11 or WET54 is. The only way to make it somewhat close is to get it to join using WDS. Unfortunately not all APs support it, so you may be stuck having it connect in client mode. If you join using client mode, the wired port is shut off as others have said.

I spent a couple days working with the Express because I wanted to replace my existing WET11 and wound up having to return the Express instead. It and my Aironet 1200 would only play nicely together in client mode, which was worthless for my needs.

It would be great if Apple would update the AE code to let it function as a straight bridge without requiring WDS. It would seem to be fairly trivial, and not everyone needs a base station repeater.

I don't know how your network is setup so I can't say if you will have problems. However it sounds like your have a both a router and the airport express handing out DHCP on the ethernet section of your network.

If this is in fact the case, the fact your network is working now does not mean it will work when the DHCP leases expire and are renewed...which is maybe why Apple says this will not work. Again not knowing the topology of your network I can't say for sure but from your description this sounds like the case.

I have a DSL router to ethernet network. I bought the airport express and a 17" laptop. I can get email and surf the web wirelessly. I can't print to the network printer or connect to iChat wirelessly. Is this a configuration issue or can't you do that with the AE?

1. Launch Airport Admin Utility on your Powerbook. Start configuring the Express. (Connect it by a cable if you don't see it.)

2. Go to WDS tab and Enable this station as WDS remote base station. Select the current network.

3. In Airport tab, Change Wireless Security... to the same settings as your current wireless provider. THIS MIGHT NOT WORK WITH WPA. If your WEP password is hexadecimal, start it with a dollar sign.

4. I assume there's DHCP on your current wireless. Therefore you don't need to Distribute IP addresses in Network tab.

5. Give the Express an IP address or just choose DHCP in Internet tab.

I actually figured this out by accident. I've read before that bridging with Express is not supported. Then I was using a cable to setup the express as WDS/Airtunes with my Linksys wireless router. But then to my surprise i noticed i got another IP from router's DHCP - through the cable!

"WPA is generally not supported over bridged connections on WiFi products due to the fact that WPA encrypts the MAC addresses which WDS relies on for communication." I see, from arstechnica.com.

Can this be done using an Express as the base station, Aexpress to Aexpress instead of Aextreem to Aexpress?
Can a airport express be setup as the main base station connected to a cable modem and another express be setup as a wireless bridge inplace of an airport card in my old i mac?

This also works for ethernet printers
Authored by: whoadoggy on Jun 06, '06 09:09:34PM

I have a Airport extreme base station that is extended by an Airport Express. Got a new laser printer (a brother HL-2070 for 100 bucks!) and plugged it in to the ethernet port (had another printer on the USB) and it just works.

Sweet little device, airport extender, 2 printer shares, airtunes, all-in-one!

Excellent tip! Connecting my PS3 to the AE Express fixed the wireless problem, and now I can stream perfectly.

Use Airport Express as ethernet to wireless bridge
Authored by: jdc5683 on Sep 30, '09 09:48:17AM

I have what may be a more complicated situation. I have a Slingbox AV in the living room, with the desire to watch television on my iMac in the den. The iMac is connected to a wired DSL modem. Because it's in an old house, I can't run wires all over the place, so connecting to the Slingbox must be done without the spaghetti.

I already have an AirPort Express in the living room so that I can use my AirTunes feature (music from the den's iMac played through the stereo in the living room).

Someone told me I must get a router which, when paired with an AirPort Express, could make all this work, but beyond that I have no clue how to establish the settings or anything. I need some help to make sure this Slingbox doesn't morph into a paperweight. The help on Sling's online (and phone line) support has not been useful. Can anyone help?

This is probably impossible. That being said...

Is there any way to extend a wireless network without physically connecting the AX via Ethernet? I'm leeching internet from my neighbors in Japan because currently the ADSL pipeline is full for my city. I plan on getting my own internet, but until then I'd rather not have to surf the internet with my computer propped up on a chair on a table in my kitchen.

Thoughts?
