Do I need two devices of Airport express to extend my Comcast router/modem?

Hi, can someone tell me if I need two devices Airport Express to extend the range of my wifi using a modem/router to Comcast?

It all depends on "how" you want to extend the scope of the Comcast modem/router.

IF... you can locate a single AirPort Express Terminal at the remote location where you need more coverage of wireless signal... And... connect the AirPort Express Terminal to the modem/router using a permanent wired Ethernet cable connection. ... THEN... the AirPort Express can be put in place to create a wireless network using the same wireless network name and password as the modem/router.  When you do this, then the modem/router and AirPort Express will act as a 'great' network with many more.

IF... you can not run the Ethernet cable from the remote AirPort Express back to the modem/router and leave only it connected all the time, then your only other option would be to use two AirPort Express devices.  An express train would be located near the modem/router and connect using a short Ethernet cable. This Express will be set to 'create' a wireless network.

The second AirPort Express Terminal can then be configured to "extend" a wireless network and wireless to repeat the signal from the first Express... assuming that the second Express is located where it can receive a strong signal first Express wireless.

  • I want to use a Terminal Airport Express to extend network provided by my Fios router/modem without going through another airport base.  Is there a way to do this?  I understand that Apple does not support this, but surely there must be a way to do this.

    Can someone tell me how to set up an Airport Express Terminal to expand Network provided by my Fios router/modem without going through an airport as a base?  I understand that apple does not support this use, but my applecare Advisor said it's possible.  Thank you!

    Unfortunately, your AppleCare Advisor is wrong if he or she has told you that an AirPort Express to extend wireless signal of a Fios router/modem.

    Function of "Extend a wireless network" Apple is an exclusive feature that was designed by Apple engineers to extend the signal from another wireless only router from Apple. Thus, the AirPort Express... or any other router Apple besides... would not be able to extend wireless a Fios network.

    SO... you have the possibility to locate the Airport Express where it is needed... And... Connect it to the Fios router/modem with a permanent, wired Ethernet cable connection, then the AirPort Express can 'extend' in this way.

    Or... If you are ready to add a second AirPort Express, connect the first near Fios modem/router with an Ethernet cable, then the second Airport Express could extend the signal first Express wireless.

    Another way to say the same thing, is that if you want an Apple AirPort router to extend wireless network... then you need two Apple routers to achieve this goal.

  • Airport express to extend my wifi signal

    I bought and set up the Airport express to extend a wifi signal in my house. I do not have an airport extreme as a base station - I thought I could use the express to extend the signal from my router/modem from verizon. Is this possible?

    Turned it "on" now, I don't see the express network as an option in my combo network - so assuming that it will seek to expand, what's the problem with it only shows not not in the drop-down list?

    The AirPort Express only wireless may extend over a network that is provided by another router from Apple.  As such, it cannot extend wireless signal router left 3rd.

    Another way of saying the same thing, it's that if you want to extend wireless network using a router from Apple, you will need two routers Apple.

    If you can connect the AirPort Express Terminal to your main router using a wired Ethernet cable connection, permanent, then the Express can be configured to provide additional coverage of wireless signal in this way.

  • How to test the signal strength of an Airport Express, which extends a network?

    I am trying to understand how my Airport Express is actually help to expand my network, and if I should move somewhere different. Any help would be appreciated!

    Current situation: my base station is an AirPort Extreme in our apartment computer room; for the internet, which is plugged into the wall. The wifi network is extended in the living room via an AirPort Express (version 7.6.4). There are on the same cabinet as the AirPort Express to Apple TV. The Airport Express has an optical cable connecting to a sound bar (which has an additional HDMI connection to the TV).

    I don't really know if the AirPort Express Terminal, he does something useful. The network is set to be extended, best I can tell: Airport Extreme network Mode is "Create a wireless network", and network Mode of the AirPort Express is "extend a wireless network. But still, the wifi on my iPad and iPhone signal strength seem to fall much in the living room. Apple TV usually broadcasts music from my desktop computer (in the computer room) well enough, but if I try to play music from my computer via the Apple Express at the soundbar, the connection is terrible and fall. (Which could be a problem with wifi, or could be an aging Airport Express question, could be a cable problem or might be a sound bar problem...)

    An example of what worries me: if I go to the Airport utility on my iPhone and a glance at the Airport Extreme, it has 4 Wireless, including Apple TV clients. But if I look at the AirPort Express, there sometimes a client wireless (iPhone), but never shows the Apple TV: even if the Apple TV is about 30 cm of the Airport Express. It's as if the 30cm distant to the Airport Express connection is weaker than the connection of two-rooms-distant Airport Extreme, but I am probably wrong that.

    In any case, is there a way to test what speed is through the AirPort Express, compared to through the extreme? I tried to use applications like CloudCheck on my iOS devices, but those only measure the speed of my network, and it is unclear whether or not he uses the Extreme or Express.

    Thanks in advance and all apologies if I used (almost inevitably) 'Express' when I should have used "Extreme", or vice versa, somewhere at the top.

    One way to see the strength of the signal is the Alt (option) key while clicking on the WiFi icon in the menu bar.

    But you see not directly related to the airport of arrival. Also the Airport utility does not give much information.

    You can see a lot more with the free app (Appstore) called "WiFi Scanner".

    The problem could be that the place you have chosen for the Airport Express can be better: it should be somewhere in halfway (in force) between the Real and where you sit with the iPad/iPhone.

  • Airport Express - to extend the wireless network

    Hello

    I have 1 Airport Extreme, make a wireless network and I have 3 Airport Express, to extend the network.

    the Airport Express Terminal 2 have connection whit Airport Extreme. The last of them is too far. The last of them can connect to one of the Airport Express 2 located in Pentecost Airport Extreme connection to expand further?

    Sorry, but no.  The distant Express which is too far can connect to one of expresses it airport who are already extending the network... so that it can be used for AirPlay or to connect a USB printer. .. .but the distant Express cannot "extend" the wireless network and provide additional wireless coverage.

    Ideally, your network could have AirPort Extreme, placed in a central location in the House, and each Express which extends the network would be located approximately the same distance from AirPort Extreme... and... ACH Express would be closer to the AirPort Extreme to another Express.

    If this is not possible, then you need to look at a wired Ethernet cable solution for at least one of the Express features, or an Ethernet Powerline solution if you cannot run the Ethernet cable.

  • How to put in place the new Airport Express to extend the current wireless WiFi U-Verse home network?

    Hello

    What are the steps for the creation of a new AIRPORT EXPRESS MC414LL/A Terminal so that it make that expand my network existing wireless, using my current AT & T UVerse equipment home.  Here are the details...

    Internet service provider: AT & T U-Verse

    Existing facilities: primary AT & T provided router/Modem: ARRIS NVG589 (reference 587234-004-00) that manages my house wired and wireless Wi - Fi.

    PROBLEM: Does not offer full Wi - Fi coverage

    SOLUTION: Attempt to add a new Terminal Airport Express so that it will extend coverage of the existing Wi - Fi network wireless.  I plan on the use of certain features such as streaming my content from iTunes to my sound, surround sound, etc Airport Express Library.

    NEW FEATURE: APPLE AIRPORT EXPRESS 802.11n Wi - Fi PART # MC414LL/A

    I wish I had AT & T equipment to continue to manage the Wi - Fi and network functionality (DNS, firewall, etc.), as it currently does.  However, I want to use the Airport Express to extend Wi - Fi coverage.  I already have a cable ethernet from the floor and the AT & T ARRIS NVG589.  I just need to know how to set up my new Apple Airport Express.

    Thank you!

    With the Express connected to Arris gateway with Ethernet, you have the basis for a roaming network.

    I would recommend that you run the AirPort Utility and allow it to run automatic installation of the Express. The utility should detect that the Express is connected by Ethernet and go through the steps to properly set up. Note: If you have made any changes to the Express since out of the box, I strongly suggest that you first perform a 'factory' reset on it to make sure that the installation went well.

  • 12.3.3.17 iTunes could not connect to devices AirPlay (Airport Express)

    After the update to iTunes 12.3.3.17 I can connect is more to Apple Airport Express.

    I updated iTunes to 12.3.3.17 on both computers:

    1. Windows 7 64-bit SP1 / iTunes 12.3.3.17 64-bit

    2 Windows 10 64 - bit / iTunes 12.3.3.17 64-bit

    On the Windows 10 computer, iTunes can connect and play all three Airport Express.  An iPod Touch can also flow to each of them.

    After the upgrade to 12.3.3.17 on the Windows 7 SP1 computer, iTunes can see all three Airport Express and they are not greyed out.  But when an any of them are selected in the dialog of speaker, iTunes tries to connect and after 30 seconds results in the error "an error occurred when connecting to the device AirPlay"xxx". The network connection timed out' and the selection is then grayed out.

    The network card on this PC, the router, and all three Airport Express everything seems to work properly as I can deliver on all of them using software third 'wing' with other applications as the source.  I can also control iTunes on the PC wirelessly from iPod with the Remote app.

    I just can no longer spread to one of the Express from the airport directly from iTunes after the 12.3.3.17 update.

    Any thoughts?

    Well, problem solved (mostly) by a lot of trial and error and it turns out be a problem of WF on the UDP ports must be open for Hello.  It was a bit of a surprise, because the Airfoil program (third party utility AirPlay) uses also Hello (that works).

    The Windows Firewall has a rule entry of inbound traffic for Hello to port 5353 UDP.  Changing the rule to allow all Ports (UDP) does the job.  So I studied what UDP ports were actually necessary for the Hello and Airplay and amended the rule again, this time replacing all Ports with these specific UDP port numbers: 554 (1900), 5289 5298, 5350, 5351, 5353, 49159, 49163

    However, that did not yet work so I ended up coming back to the all Ports configuration.

    If someone uses the firewall native Windows (preferably Windows 7, but probably the same for 8 and 10), I would be interested to know what UDP ports allows your Windows Hello firewall.

    Control Panel > Windows Firewall > advanced settings > inbound rules > Hello

    I had certainly not changed firewall settings before this update to iTunes (and AirPlay worked just hours before) and know not why the update seems to have changed the Windows Firewall settings, but that helps to explain why the Windows 10 computer worked fine after the update, because she was using the McAfee Security Suite firewall.

    Thank you!

  • Airport Express. Connect to a router home without another device from the airport.

    Looking to buy an AirPort Express station. Plan to connect it to my home router to boost connecting devices and to create the network or guests. This work if I just plug my Express in the router with a cable Ethernet or you will take another product I.e. time capsule to work? The router can also activate "Modem Mode"

    What model is the modem?

    Comments wireless is disabled in all apple routers when they are used in bridge mode... This will mess up your idea to connect to main router... the express (or any wireless router) should then be in bridge.

    If you can fill the main modem... It is pure modem and run the express as a wireless router, then it can produce a network of comments as well... However, Express is slow and far from adequate as a main network router... unless you talk real slow ADSL etc.

  • Connect AirPort Express to lemon (Rogers Rocket) Wireless Modem/Router

    I just got Rogers Wireless internet new modem/router Hitron.  I use modem/router mode.  It's great. Very fast and a lot of range. Covers all 3 floors of my house.

    I want to connect an Apple Terminal to my Hitron router with an ethernet cable and put the Hitron in Bridge mode. I want to continue to use the Hitron router as my main and only router.

    However on another floor, I would use an Apple Airport Express connected to my stereo with a jack 1/8 '' to play my music wirelessly from my iTunes from Apple.

    To do this, I need this Apple Airport Express Terminal to 'find' the Hitron router.  How can I get to find the router Hitron?

    I guess that you have a current version or recent of the AirPort Express with the default settings.

    As long as the AirPort Express is located where it can receive a strong signal of the modem/router...and wireless Hitron the Hitron aircraft provides a wireless signal that uses industry standard wireless settings, the AirPort Express can 'join' the wireless network. Wired Ethernet is not necessary.

    Note that the AirPort Express will not "spread" or "repeat" the signal from the router/modem lemon to provide additional coverage of wireless signal wireless, but it can be used to join the wireless network and provide a signal of airtime for your stereo.

    Simply use a Mac running a current or recent operating system, or an iPhone/iPad and configuration "Wizard" Apple to set up things upward. The wizard will automatically offer the correct configuration to 'join' the wireless network. All you really need to do is to enter a device name that you want to use for the AirPort Express and the password of the wireless network and confirm.

    Start the wizard by clicking on AirPort Express under the title of the new AirPort base station.

    On an iPhone or iPad, the screen looks like this:

    In the example below, the wizard has detected a network named "2WIRE902" for the AirPort Express join. You will see the name of the wireless network that provides the Hitron modem/router on your screen. Just enter a name of device for the Express, then type the wireless network password, then type it again to verify.

    Click next at the bottom right of the window and the AirPort Express displays a green light for a minute or two and you're done.

  • Airport Express to extend

    I have an existing using a Belkin ADSL2 + 4 port modem and a Double N + Router Belkin Wireless.  These are both located in my study.

    My House is wired so that it has two ethernet ports in the wall of the study that point to other parts of the House - one for the living room on the ground floor and one in the living area upstairs.

    The wireless signal in the lounge downstairs is okay, but not much.  Upstairs, he's weak.  Wanted to improve the signal throughout my house, so I bought two Airport Express units.

    Initially, I plugged an Airport Express into my living room via Ethernet DRC and it seemed to work.  The signal in this area seems to improve, but I don't have all the numbers to back up this feeling.

    Then I plugged the second Airport Express Terminal on my floor living room via Ethernet and now, it doesn't seem to work properly.  The signal on the floor is certainly not improved.

    Any ideas?  Maybe I did not give sufficient information at this stage, but I don't know what could be relevant.

    Thank you

    Initially, I plugged an Airport Express into my living room via Ethernet DRC and it seemed to work.  The signal in this area seems to improve, but I don't have all the numbers to back up this feeling.

    We must first check that the AirPort Express in the area downstairs is working properly until we can address the issue with the first floor of the AirPort Express. Please be patient with this process, there will be additional questions based on the answers to the first two questions below.

    (1) where this airport located Express regarding the Belkin modem/router?  In other words, how far from the Belkin device is the AirPort Express Terminal?  How many walls or other obstacles between the Belkin device and the Express down?

    (2) only the low AirPort Express provide a signal of wireless network that uses the same wireless network name and password as the Belkin modem/router...or...does AirPort Express Terminal provides a network that uses a different wireless network name?

    (3) you have Mac laptop which allows you to check some network settings?

  • Connect an airport express to extend wifi

    I'm not tech savvy... I had an addition on the House and our wifi is weak. I have a Timecapsle and tried to plug an Ethernet cable and bring it up to the addition where I would place the Airport express.

    I can't work. Can someone walk me through the settings?

    I currently have Ethernet plugged into one of the ports in the timecapse and then plugged into the Ethernet port on the Airport express

    We need a little more information to be able to help – tips and tricks for airports depend on the model you have and the computer that you use to configure the airport.

    Your AirPort Express look like this?

    Or, your AirPort Express there than a single Ethernet port, like this?

    If it has only one Ethernet port, that we need to model on the side of the unit number. It is difficult to see gray inscription on white background, so you can need good lighting and reading glasses to see clearly. The model number starts with an 'A' follow-up of four digits. Post back with that info, please.

    The next point, we need to know what device you are using to configure the Express... .a mac?... a PC?... an iPad or iPhone?

    If you have a Mac, we need to know what operating system they are running. If you are not sure about this, click on the Apple icon in the upper left corner of the screen, then click on about this Mac and post back with the Version of OS X number that you see there.

    Finally, we assume that you have tested the Ethernet cable that will connect to the time Capsule to the location of the AirPort Express Terminal by connecting a computer or laptop to the Ethernet cable temporarily, turn off WiFi and checking to make sure that you get a good connection Internet in this way. If you can, then the cable works fine.  If you can't get a good connection, then you will need to resolve things first, before you can try to plug the AirPort Express Terminal.

  • Airport express at slow speed of the modem Arris SB6190

    Hello!

    My so-called WIFi Comcast gives me 150Mbps. My test only show 70 or slower speed on a WiFi test. After the call to them they told me to talk to my modems customer service. But their customer service is terrible. Here is my setup and yes everything has been switched off voltage and reset. And Comcast has been created with the modem while the Comcast guy was here. From the start after a few hard reset the express worked. Here's the question and the installation program.

    I have a SB6190 (not wireless), Arris directly connected to my Airport express. The express (which deals with my wireless connection) is connected to a switch (for wired devices). But I think that my problem is the Express. ? Not sure, I guess my question is I do something wrong in public services from the airport with the Express settings? I do not see why I get more 75Mbps wireless. Or maybe Apple if your reading, you can give it a fix on your next update. Hope you can help and thanks!

    Here some thoughts:

    (1) the Airport Express uses 100 ports Ethernet of Mbit/s, so the theoretical maximum speed that could be achieved with an Ethernet or Wi - Fi through the Express would be 100 Mbit / s.

    (2) the Express is not known for his speed wireless. On a connection of 100 Mbps Internet here, I see usually 45 - 50 Mbps at best more wireless, no matter if the 2.4 GHz or 5 GHz is used.  Ethernet checks better about 75-80 MB/s to the Express LAN port.

    (3) these are user to user support forums, so it is very unlikely that anyone from Apple will ever see your post. If you want to provide feedback to Apple, you can do so here: Apple Apple - AirPort Express - Feedback will acknowledge receipt of your message, but they will not respond after that.

    (4) the AirPort Express was introduced almost 4 years ago and it's been 2 years that Apple has provided an update firmware for the product, so additional updates are not probably... my opinion.

    I want my airport express (model 1382) to be subordinated to the time capsule (ver. 7.7.3) and I'm on a different network. Is this possible?

    Do not know what you mean by 'subordinate' here... and you do not specify if the AirPort Express terminal connects to the Capsule using a permanent, wired Ethernet cables... or... If you want to try to have the AirPort Express to connect wireless to the time Capsule.

    The method cable would be far superior to the method wireless in terms of performance and 'slide' on the Time Capsule wireless.
