Airport Express in client mode to serve Airport Extreme

Hi guys,.

I am struggling with Setup in our business that is pretty special. Our cash register, the Bank Terminal and the control system are all serviced by an Airport Extreme that was configured with care by a dedicated company. The extreme is powered via an Ethernet based modem. The basic modem is a box any of the internet service provider in our country that has four ethernet ports and a basic WIFI network that we open for customers. As the basic modem is too far from the extreme, a powerline sitecom was initially used to carry the signal to the modem from basic to the extreme.

But the powerline connection was poor, so they advised me to replace the powerline by an Airport Express in client mode, which converts the client base modem wifi signal ethernet to the WAN port on the extreme. I installed the Express exactly as described by Apple (AirPort Express: how to join an existing client mode - Apple Support Wi - Fi network) and the entire installation ran smooth for about an hour. At a time of seemingly random, all of a sudden the extreme complains that the internet connection is lost. In airport utility, the extreme flashes green, but the internet icon is orange and the notification indicates that the connection is lost. However, the Express flashes green and is always connected to the WIFI which worked again properly, I confirmed. Restart the extreme and Express to solve the problem, but only temporarily. After some time, the extreme complained again that the internet is lost.

Can someone explain what could cause this problem and how to solve? Thanks in advance.

From your description, I guess that the WiFi connection between the base modem and the AirPort Express is where you need to solve problems more far. Looks like that the modem is not a simple modem, but a combination modem and the wireless router, also known as the name of a gateway device.

Nevertheless, the best solution would be to use an Ethernet cable dedicated between the "modem" and the AirPort Extreme. Bypassing the Express all together. The next would be Powerline adapters. I'm a little surprised that those you used works well for you. Unfortunately, the scenario of 'worse' bandwidth performance is what you're doing now is to use the AirPort Express as an Ethernet bridge Wireless Terminal

However, if you have no other choice in the matter, where you then place the Express can make a difference. You want to Express to be in a db 25 + range of report Signal to noise (SNR) of the modem. This will allow the Express maintain a connection compatible with this modem wireless network. To find out how to measure SNR, discover the next Tip of an airport users for details. Please post back your results.

  • Airport Extreme is adjustable upward in client mode?

    I've set up the Express in client mode before, but I'll have set up extreme. During setting up he sees that I am on an existing network, but he doesn't know that and wonder if I would create a new. When I try to connect to an existing network, it indicates that an unexpected error has occurred. I also tried to set up a new network and then in the utility existing Airport to connect to the network. He takes the password and restarts and then never reappears in Airport utility, after I switch back to the existing network.

    AirPort Extreme is adjustable upward in client mode?

    No, do not use any version 6.x of AirPort Utility.

    Maybe, if you have an old 'flat or square' in the form of AirPort Extreme and you can use an older version 5.x of AirPort Utility to maybe put in place.

    But even if you could do that, the extreme doesn't really matter in client mode. The Ethernet ports are not enabled, and the extreme would not "extend" or "repetition" of the network. The only thing that would work would be the USB port, which runs at half the speed of a USB 2.0 standard.

  • Airport Extreme router's Express is connected by wire, East of 1 Gbps ports on switch it extreme on 100Bt now?

    Hi all

    In my house, the extreme is connected to a fiber modem 250 / 250 MB/s and I plugged a time Machine as an Express via CAT6 UTP. All serve as a router and provide 2.4 and 5 GHz wifi on the different floors of the House. Just a question: Express has 2 ports ethernet 100BT, Extreme and Time Machine have 3 1000BT Ethernet ports. The extreme switch mode back all 100BT because of the Express ports?  Because that would explain the downgrade in the port on the extreme speed after that the PS3 has been used connected to the Express.

    The extreme switch mode back all 100BT because of the Express ports?

    No.... but any device connected to the Terminal AirPort Express will have a maximum speed of 100 Mbps. So, if you connect a 1 000 compatible device to the Ethernet port on the Express, it would appear as a device of 100 Mbps on the network as the Express is limiting speeds.

    So, if you want a device that is capable of 1 000 Mbit/s to have 1 000 Mbit/s speed on your network, it will have to connect to AirPort Extreme or time Capsule.

  • Second Airport Extreme in Bridge mode, ethernet ports does not

    I have two routers, I want to use. The first is a time Capsule (old model 2 TB) connected to a single cable modem. The second is an Airport Extreme (also a little older, the 'flat' last body model until they began to sell towers). Both have the 7.6.4 firmware.

    The problem is that I want to use the second to extend my network, but I don't want to use wifi. I have the second of the WAN port connected via an Ethernet cable to the network served by the time Capsule, but when I launch the extreme in Bridge mode with a Mac Pro plugged into one of the ports ethernet to the extreme, it says it is not connected to the net.

    Y at - there a trick to getting the second router work ports ethernet when used in this way?

    Thanks in advance!

  • Got an Airport Extreme, you want Airplay with Express?

    Hello. I have an old Airport Express (the one that plugs into the wall) and recently replaced with an Airport Extreme. We love it, and our speed is more limited, but now we do not have our AirPlay speakers. I want to return and I was wondering if there was anyway I could have the Airport Express set up JUST for AirPlaying these speakers. I'm not all devices to try to get internet from this slower base. The two airports would be less than 3 feet on the other. Is this possible? To make the only function of the airports for Airplay while being able to play through our existing Airport Extreme network? They would interfere with each other?

    I have an old Airport Express (the one that plugs into the wall) and recently replaced with an Airport Extreme.

    The old 802.11 g (model # A1084) and the 1st generation 802.11n (model # A1264) AirPort Express base stations look identical. Which do you really?

    ... but now, we don't have our AirPlay speakers. I want to return and I was wondering if there was anyway I could have the Airport Express set up JUST for AirPlaying these speakers.

    Yes, you can have the Express configured to join the network wireless to the extreme as a wireless client. Since the Express will be a wireless client that it will behave like any other client on the network. In other words, it won't be a wireless broadcasting, nor as a router.

  • Four express airport Wireless extends through the other, instead of directly through my airport extreme

    Hello

    I have a small question which I hope someone can help me with.

    I have an airport extreme that I use as base station, and since I live in a big house, I extended wireless network with four Airport express devices. I put express devices from the airport in mode "expand the network."

    The question I have is that two of the expresses correctly connects directly to the Airport extreme, but the two other go via the two expresses first and not directly to the airport extreme base station.

    I am worried that I have will lose speed because of this and wondered if I can implement all the features four Airport express way so they all connect directly to the base station and not by the other?

    Any advice would be appreciated - thanks.

    I am worried that I have will lose speed because of this and wondered if I can implement all the features four Airport express way so they all connect directly to the base station and not by the other?

    Apple "extend a wireless network" feature works on the strength of the signal, so the ideal situation would be to have AirPort Extreme, located within your home with each Airport Express located approximately the same distance from the AirPort Extreme around the perimeter of the House.

    Think of a 4-spoke wheel. AirPort Extreme would be the "hub" in the center of the wheel and located at the end of a ray separated from each AirPort Express Terminal. In this way, each AirPort Express connects directly to the 'hub' and expand properly.

    The question I have is that two of the expresses correctly connects directly to the Airport extreme, but the two other go via the two expresses first and not directly to the airport extreme base station.

    The two airport expresses which connect to other expresses 'extension' of the network are not all. They 'join' the network... so they could be used for AirPlay or a printer USB remote... but the Express do not 'extends' the network when he "joined".

    You will need to experiment with different places until you see all four expresses connect directly to the main AirPort Extreme.

    As loss of speed in the network is... whenever you try to extend wireless network, nearly half of the potential speed on the network will be lost in the process. It's just a character of the beast to the extension of a wireless network.

    You can avoid the loss of speed in the network by configuring each AirPort Express Terminal to connect to the main router using a wired Ethernet cable connection. There is no loss of speed at all through the connection Ethernet cable up to 300 + feet, so full power is stored on the network when you do it this way.

  • How to extend the range of my Airport Extreme Base Station (802. 11 a, c) using a relay of Airport Express (802.11n).  Airport Utility (V635.2) says that this version does not support the relay.  That is what it is?

    How can I extend the range of my Airport Extreme (802. 11 a, c) using an Airport Express (802.11n) point.  Airport (V635.2) utility does not recognize the Express on its screen?  I have to buy equipment?  I'm on a MacPro OS X 10.10.5.  Thank you.

    AirPort utility that ships with OS X 10.10.5 supports base stations as 802.11ac & 802.11n AirPort. It should be able to configure both of your base stations for a scope (wireless connected base stations) or roaming types (base station connected Ethernet) wireless networks.

    When you initially configure the Wan, it helps to keep the two base stations in the same room. Once configured, you can move the base station that extend to the desired location. The important key is that the final positioning of the station that extends the base must be understood that it's to expand in order to maintain sufficient bandwidth to the station remotely for clients from network connected.

  • Airport Extreme + Express + older Express audio dropouts

    My setup is as follows:

    Coaxial cable-operator-> cable modem provider-> Airport Extreme via Cat5e

    Express #1 a few feet away, analog stereo output, extreme network expansion

    #2 2 parts away, similar stereo out, Express extreme network extension

    2014 Macbook pro, Yosemite

    When I broadcast iTunes on Express #1, is generally well from anywhere. When I listen to #2 (either by itself or in addition #1) I get occasional audio drop outs anywhere, the macbook is, even though my internet remains stable. For example, the macbook is right next to the Express #2, streaming internet radio and play through internal speakers. When I send also the audio to Express #2 (multiple speakers in itunes), which express audio stream is sporadic, although the internal speakers turned on constantly. I would have thought dropouts would leave as the macbook approached #2, but there is virtually no change.

    If the macbook is right next to the #2 Express, he continued directly towards the #2 or that made a trip to the extreme and #2? Possible Express #2 is working to expand the network ok but does not just for airplay? It is a first or second generation.

    Thank you!

    What are the exact models of each of your airport base stations?

    When I broadcast iTunes on Express #1, is generally well from anywhere. When I listen to #2 (either by itself or in addition #1) I get occasional audio drop outs anywhere, the macbook is, even though my internet remains stable.

    The main path that AirPlay takes when streaming to your configuration is:

    • Starting from the host of iTunes MacBook to AirPort Extreme.
    • Extreme for:
      • Express #1 if this Express is chosen as the "speaker" AirPlay, or
      • #2 has been chosen as speaker, express or
      • At the time, if the two were chosen as speaker.

    Thus, it is possible that the path includes several obstacles (walls) for AirPlay to go.

    If the macbook is right next to the #2 Express, he continued directly towards the #2 or that made a trip to the extreme and #2?

    AirPlay, in theory, go first to the base station that iTunes host is connected to.

    When you extend, you lose a significant amount of bandwidth just to keep the network wireless in this configuration. So the question is: do you really need to expand your network or continuously more important for you?

  • How can I configure my Airport Extreme in Bridge mode (use the 3rd party router)?

    Data sheet:

    Airport Extreme - v 7.7.7

    Luma Surround Wifi 8

    I recently bought a wifi (luminance) surround system.  It comes with 3 routers that you place around your home.  Unfortunately I still have stains died in my house I'm looking to add my Airport Extreme (AE) to Luma network.  Is it as simple as plug the AE to the network (via Ethernet) and the bridge mode selection in the configuration of EI?

    I can see the AE of my iMac, and it is green.  How do you know that actually extend the wifi of my router Luma range?

    I searched the forum and all messages dealing with this are several years old.

    Thanks for your time...

    Basically, you want to create a mobile network with your Luma and AirPort Extreme routers. As you said, the extreme would need to be connected to the luminance by Ethernet and reconfigured as a bridge.

    In addition, the following are also required on the extreme:

    • Wireless mode: create a wireless network
    • The network name must be the same as that used by the Luma.
    • The type of wireless security and the password must match that of the luminance as well.

    To 'know' that the extreme extends the network of Luma, simply consult the BSSID value in the drop-down of OS X Wi - Fi. It must match the ID of the airport on your base station. Note: You must hold down the option key before clicking on the icon of the free Wi - Fi connection.

  • I have older Airport Extreme and Express but I now want to set up a new router Airport.

    I have an old Airport Extreme as my main hard wired (ethernet connected) router and an Express that I use as wifi Wireless extender.   Now, I want to set up a new Airport (probably Extreme) router and use the old Airport extreme as extender wifi hard wired (ethernet cable).

    I know that I have to reset the old default airport routers. But, how I do this and please start from there and the beginning, their reset and then up to the new Airport base station and then configure the older router to use with the new? Please be detailed, step by step and attach written instructions or places that I can get the instructions.

    What exact models are each of your airport base stations? Once we have this information, we can help you get your properly configured access point.

  • Failure of the Airport Extreme and Airport Express

    Airport Extreme not to talk to the device POE from the antenna of radio after a thunderstorm (lightning).  Plug the POE ethernet cable directly into Mac works.  Airport Express lights.  Airport Extreme appears, but there is no internet connection.  A port can be fried on the Airport Extreme?

    Yes, but unfortunately the port that will blow is that ethernet is plugged.

    If it's WAN then you do not have a way to use the airport as a router... only a bridge device.

  • How to extend a WiFi router network not Apple using Airport Extreme and Express?

    My cable ISP company just gave me a new modem/router - a DG of Arris - 2470. For the last two years I used a cable modem independent older with a connected Airport Extreme (both located on the ground floor) and an Airport Express station on the floor as an Extender. I was very happy with the power of the signal around the House.

    Since his arrival to the Arris router my signal has become very low to the floor. I would use my two Apple devices to extend/boost my network, but do not know how to do this.

    Thank you!

    Basically, you have two options:

    1. (Best overall performance of the network) Connect the extreme and Express on the Arris Ethernet gateway device and configure all for a traveling-type network. This would require an Ethernet connection between all routers that can be accomplished by either using Ethernet cable or the use of mains adapters.
    2. (The overall performance of the adequate network) Simply connect the extreme to the Arris Ethernet, then extend the extreme using the Express.

    Which of these do you prefer?

  • Problem of AirPort Extreme with AirPort Express network expansion

    I have a dual-band Airport Extreme 802.11n that I bought in 2012 which is currently my home wireless network. I am trying to extend the network with a new AirPort Express with the AirPort 6.3.6 utility running OS 10.11 on an iMac. The Airport Express appears in the option other Wi - Fi devices. When I select it, AirPort utility tries to connect and then I get this message "an unexpected error has occurred. Try again. "Try again does not lead to a different result, and I can't seem to find useful information in the documents support or conversations. Any suggestions? Thank you!

    It should be easy enough to operate the express, but you must tell us all the info.

    Configure the Express in the same room as the extreme.

    Using wireless to expand? Then you simply plug power in the Express... and it should pretty much automatically connect to the extreme.

    If you want to extend through ethernet, you should connect the Express in the extreme and make sure that the configuration of the airport utility selects extend by wire.

    If the Mac does not work you have the iphone or ipad and use Airport utility for iOS... it tends to be more reliable.

    Still no luck does your Mac have port ethernet... in this case, you can plug it into the computer with ethernet and try again... more wireless implementation looks like sawing off the branch to that which you are sitting.

  • is there a way (or an app?) to set up a local proxy server on the airport extreme or time capsule?

    Hello

    If you have the answer! I'll be so happy!

    is there a way (or an app?) to set up a local proxy server on the airport extreme or time capsule?

    Thanks for your time!

    BR,

    Stéphane

    All routers, including the AirPort base station, run as a transparent proxies for the local network behind them. However, if you are talking about the possibility of proxy requests between the LAN and Internet, then no, the airport base stations do not have a native function to support doing so.

    The two common methods to accomplish this are: 1) use a proxy on your local network, or 2) use a DNS, like OpenDNS service, which offers proxy services.
