Using an Express to create a closed network

I have a home automation/control system in place. All of the touch panels communicate via ethernet. Three are wireless devices using 802.11g to hit a WAP which is then cabled to the head end processor.
One of the WAPS on the system died last night. (I did temporarily slap in an old linksys WAP4400 which worked after pointing the wireless devices to the net network name) but I want to replace that closed network with 2 air port expresses. (by closed i don't mean hidden but rather a network that doest have a connection to the internet and no modem connected)
I'm wondering if should set up one express to share a public ip and the other in bridge mode or since this network does not hit the internet and is a closed network is there a more appropriate setup.
Also can two ABExp be set to create a wireless network, in bridge mode and with the same ssid and security settings or does one have to be set to share a public ip address or some other setting?
Thanks in advance
Marc
Thanks in advance.

Are these AirPort Express devices connected to a hub via ethernet cable connections, both wireless, etc.?
You can do what you want, you'll just need to click the "ignore" box when AirPort Utility informs you that you don't have an Internet connection, there's no ethernet cable connected (if applicable), etc.

How can I use Airport Express to create a standalone Wi-Fi network without Internet Access so I can browse web pages on the local network? I will be using MAMP as my server (Apache)

I would like to create my own Wi-Fi standalone network at an upcoming tradeshow where there will be NO internet access.
Currently, I run and develop sites on my iMac use MAMP to manage my sites locally. Using MAMP, I run my sites as though they are on the internet although everything is local.
I purchased an Airport Express hoping I could create a standalone network so that the iMac would broadcast its website to whatever device connects to it such as my iPhone, iPad and MacBookPro.
However, after setting up the network successfully (I have a green light on the Airport Express, and there is NO internet going through it), I am not able to go any further by logging into the iMac's websites from the other machines. Form my MacBookPro Finder, I can look at files and folders using afp://10.0.1.2, from the Find/Go/Connect to Server utility, but I can't browse the website that is running on the iMac via the Safari browser.
Can anyone help me configure my MacBookPro (or iPad, or iPhone) to run the website on the iMac when they are all on the same network?
Thanks so much!!

1) connecting the TC using a ethernet cable from one of the two modem's LAN ports to the TC's WAN port
2) create a new Wi-Fi network using the TC ?
Does someone already create a new Wi-Fi network using its TC connected by Ethernet on a modem/router device ? How do you set up the DHCP (and NAT) ? Which range did you use ?
This is easy enough to do..
Plug the TC directly into a computer.. without other connections to do the setup.
Using the newly installed 5.6 utility.
Bridge the TC.
Create a wireless network.
This is an older screen shot and I would set security to WPA2 Personal only not WPA/WPA2 Personal as shown above.
I do recommend you use wireless names that are short, no spaces, pure alphanumeric.
Update the TC..
Now plug it into the modem router.. it will be a part of the network without doing NAT and DHCP itself.. which you do not want.. that leads to double NAT issues.. but it is a WAP that provides access to devices on both 2.4ghz and 5ghz bands directly to the main router.

Can I use airport express to create a local wireless network that my apple tv can connect to for AirPlay/mirroring in student halls/dorm without Internet connection

Hi I was wondering :
Would I be able to make a local wireless network using airport express that my apple tv can connect to which in turn is connected to a projector with hdmi in so that I can mirror/AirPlay from iPhone pad and mac

will the Airport Express allow you to log onto a hotel wireless network, and broadcast a secure wireless network in your room for your wireless devices, like the Ipad, Iphone, etc.?
The bottom line with a single AirPort Express is no.
The AirPort Express can only "extend" a wireless network when the network is being provided by another Apple router.
As you might imagine, it is extremely unlikely that that the hotel network....which no doubt uses professional wireless access points provided by a manufacturer of commercial systems.....would be compatible with an AirPort Express.
In many years of travel domestically and internationally, I cannot recall a time when a single AirPort Express would "extend" the signal provided by a hotel's wireless network.
However, if you had two AirPort Express devices handy, you might be able to configure one to "join" the hotel network and provide an Ethernet signal to the second AirPort Express, which would be configured to "create" your own "private" wireless network.

Can I use my AirPort express to create a wireless network in my uni room?

So, I'm going to university in september and my room has an ethernet port to connect to the internet. If I buy an AirPort express, can I plug it into the ethernet port to create a wirelss network in my room?

The quick answer is yes. However, You should check with the appropriate University authorities to make sure they will allow it (some do not) If they agree, they may offer you a tutorial as to what you need to do to enable it.
Many business people utilize the Airport Express to provide the convenience of Wi fi in their hotel rooms, if the hotel doesn't supply an in house Wi Fi system.

Using Time Capsule to create a wifi network from a Powerline Adaptor

OK, before I ask my question, I just have to 'paint the picture'.
I live in a work residential complex, with wifi provided. However this wifi is awfully weak, to the point that I can only sit in one spot to receive it, and then it still drops out. I tried using an airport express to extend the signal, but the wifi router won't allow it.
Through the company that provide the service, I am know using a powerline adaptor ( you know the sort; one ethernet cable from router to adaptor, and another from adaptor in room to laptop) and I get broadband.
I'd like to find some way of getting wifi from that, to my mbp, iphone and appletv all on the same network.
Ok, the crux, I want to buy a Time Capsule, if I do so, by plugging the ethernet cable from powerline into it, will I be able to create a wifi network that 1. Allows devices to connect to it, and 2. Access the Broadband service.
Hope that's clear ;-)

Yes and yes.

Using Airport Express to create a connection between two Macs

We have two G5s in the office, one of them has built-in Airport and the PowerMac doesn't. We have Airport Express but we aren't sure whether it can be used as hardware to allow the non-built-in-Airport G5 to HAVE wireless access to the other Mac's files and so forth...
In other words functioning as a server connection or a network between the two.
The Airport Express didn't come with a USB cable, thus my suspicions.. Is this meant to be used solely with Macs with built-in Airport?
Many thanks,
Anne

The USB port on the AirPort Express (AX) is ONLY for a single compatible USB printer.
The AX can be used to allow a non-wireless computer connect to a wireless network (via it's Ethernet port) ONLY if the AX is configured to use WDS to connect to the wireless network. If the wireless network is created by another AX or an AirPort Extreme base station (AEBS), using WDS is possible.
Be aware that each WDS link cuts your available bandwidth in half.

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.

How do I use airport express to extend my wireless network?

How vcan I extend the range of my wireless network using Airport Express?

It appears that you may have "join a wireless network" and "extend a wireless network" mixed up a bit.
The Express can "join" virtually any wireless network produced by any manufacturer's router if it is provided with the correct settings:
name of the wireless network
the correct wireless security settings
and correct password.
"Join" is normally used for AirTunes or to connect a USB printer to the Express for remote printing.
But, the Express does not provide any additional wirless coverage when it "joins" another wireless network.
Apple's "Extend a wireless network" feature, which was introduced about 5 years ago, allows the Express to connect to another Apple "n" wireless router and then "repeat" or "extend" the wireless signal....providing more wireless coverage in the area where the Express is located.
This is a proprietary setting. Apple says it will not work with devices from other manufacturers. To our knowledge, this is correct.
Prior to 2007, Apple used a setting called WDS to allow the Express to be configured to provide more wireless coverage. Attempts were made by a number of manufacturers to standardize the WDS settings, but things were never finalized.
The result is that Apple's older "b/g" routers were sometimes compatible with WDS settings from another manufacturer. There were a handful of products....5 or 6, as I recall....that were said to work. Some did, some didn't. Linksys had a couple of models, Netgear had one, SMC another, etc. Extremely limited.
Since WDS was never adopted as an industry standard, manufacturers developed their own WDS settings. Compatibility was extemely limited and unreliable. That continues to this day with WDS.
Bottom line....It is always best to stick with the same manufacturer throughout your network as far as routing is concerned.
If you have an newer "n" Apple router like an AirPort Extreme, the Express can extend the wireless as can along Extreme. If your Extreme is dual band, and you want to extend both bands, then you need another Extreme.
Another responder suggested to someone that they could connect the AirPort Express to a router via Ethernet. What exactly would that achieve?
That is a completely different subject since this discussion is about extending a wireless network using wireless only.

Do you have to disable your Wifi on your existing Reuter if using time capsule to Create a new network

Does one need to disable the wifi on ones reuter if using a time capsule to create a new network what happens if you don't and what are the benefits of doing so

No but you may experience a bag of hurt from cross channel interference. You may have to reset the Subset Mask of one of the routers along with separating the broadcast channels.
Further if you then have one device a PC perhaps on one network and your Mac on another you may not be able to share files/ITunes etc.... with any ease.
So switching off the Wifi on the router/modem and hanging an Ethernet cable to the Time Capsule and setting that up as your WiFi router distributing the IP addresses over DHCP really is the least problematical approach.
IF you have cable Internet with a decoder with Ethernet output ditch your old router completely !

Using the iMac to create a wireless network. Is it possible?

At my college, we are not allowed to have routers. We can use switches that allow us to share the connection among many computers. I have a wired Intel iMac. I want to know if I use iMac to create a wireless network that way I can connect my Nintendo Wii and Nintendo DS.

It is not possible to do this, but this will solve your problem:
Wireless-G Linksys Access Point
Add High-Speed Wireless Access To Your existing Wired Network!
This is not a router, so you are probably allowed to use this. This will bridge your ethernet signal to a wireless signal.
Hopefully this is helpfull or solved your problem.

Using Airport Express to extend my wireless network

I recently purchased a Time Capsule but found that I could not see the wireless signal from my bedroom. To solve this I purchased an Airport Express to extend the range. I plugged the AE into an outlet in my bed room and set it up to join my existing network. Everything looked fine from the point of view of the Airport Utility. Unfortunately my iPod Touch still can not see my wireless network from my bedroom. I new iPad can see it but the signal is very weak, even when I hold it right next to the AE. Is there a setting I missed?

Rick, welcome to the discussion area!
I plugged the AE into an outlet in my bed room and set it up to join my existing network.
You need to configure the AirPort Express to "Extend a wireless network". The AX does not provide any additional wireless coverage when it is set to "join".
First, you need to check a setting on your Time Capsule as follows:
AirPort Utility > Manual Setup > Wireless tab (below the icons)
Make sure there is a check mark next to "Allow this network to be extended"
Update to save any changes
On the AirPort Express move it close to the Time Capsule for configuration:
AirPort Utility > Manual Setup > Wireless tab
Wireless Mode = Extend a wireless network" (Hold down the option key on your Mac if you do not see this choice appear when you click the selection box).
Wireless Network Name = Same name as your Time Capsule Network
Check mark next to "Allow wireless clients"
Security = Same setting as your Time Capsule
Password = Same password as your Time Capsule
Confirm Password
Update to save settings
The AirPort Express can only "extend" what it "receives". Most users position it too far away from the main router and consequently, the Express extends a weak signal. Try a location that is about 1/2 to 2/3 the distance between the Time Capsule and the area that needs move coverage. Then experiment a bit to find the best signal.
Post back on your results.

Use Airport Express Brick N to extend network via ethernet

I have the old brick-style Airport Express N model, which I'm currently using to extend the newer Airport Express hockey puck. The hockey puck is setup to with DHCP and creating the network. The brick is in setup to extend the network using DHCP and in Bridge Mode. When I plugin the Ethernet cable from the Ethernet port of the hockey puck to the brick, I lose all internet connectivity. I seem to recall reading some documentation that said the brick would support ethernet rather than just over-the-air. Thanks for your help!

My question is: can I connect the two via ethernet cable to the extending is happening over the air? I'm not sure the brick is capable of this?
It is possible to "extend" in two different ways:
1) Extend using a wireless connection between the AirPorts. Apple calls this "extend using wireless" during the setup. When you extend this way, about half of the potential speed on the network is lost.
2) Extend using a wired Ethernet connection between the AirPorts. Apple calls this "extend using Ethernet" during the setup. When you extend this way, full bandwidth on the network is maintained since there is no signal loss in a wire.
If you want to "extend using Ethernet", the 2nd Gen AirPort Express must be the "main" router, so you will need to reconfigure it for that purpose. The 1st Gen will also need to be reset back to default settings and reconfigured as well.
Once the 2nd Gen Express is working correctly as the main router, connect an Ethernet cable from the LAN <--> port on the 2nd Gen Express to the Ethernet port on the 1st Gen Express and use AirPort Utility for the setup.

How do I use Airport Express to extend my current network.

I am now using an Airport Extreme and want to use my old Airport Express to extend my network. How do I do this? Thanks!

Linc44, welcome to the discussions!
I am now using an Airport Extreme and want to use my old Airport Express to extend my network. How do I do this?
By "old AirPort Express", I take it that you have a "b/g" version of the device, which is model number A 1084. Is that correct?

Airport extrem working with expresses to create a powerful network, but how

I have one extreme base station and 3 expresses in a 3 story house with a basement. My network base is on the 3rd floor and I want the base station to link from that one to others to boost the signal. I thought I had it all set but am not getting good signal at all. If some one could give me steps to doing this and also give me tips on making the signal better. Thanks. Post here or email me at [email protected]
Oh and I have 8 total computers: 4 pcs, 1 Powerbook G4, 2 Imac Intels, 1 Macmini intel.
3 Pcs are hard wired the other wireless and all the Macs are wireless.
There is a dlink systeme set up that was implace before and used for wireless but with the new Macs im switching to Airports. Should I git rid of the Dlink wireless router?
Let me know if you need more info, thanks again.

You will need to replace the D-Link with the Airport Extreme.
Step 1
Configure the Airport Extreme so it is working as a single wireless router - do not touch the WDS tab in other words where it was before you started.
For ease use a new network name and security.
If necessary do a reset.
Wait ten minutes
Step 2
Factory reset the Airport Express.
Plug the Airport Express in.
On your Mac remain connected to the Airport Extreme wireless network.
Run the Airport Assistant say that you want to configure a new base station.
It should find the Airport Express and ask you some questions, confirm that you want to extend the network of the Extreme network, in other words extend an existing network.
Once it has configured both Airports.
Wait ten minutes.
Repeat Step 2 for each of the remaining Airport Express units.
You may want to reconfigure the middle Airport Express as a relay unit instead of a remote unit.
You are good to go.
