AirPort Extreme Plugged Into Router Connected to Cable Modem

If I plug my AirPort Extreme into an ethernet router that is connected to my cable modem, will this interfere with the AirPort Extreme's ability to operate? I ask because I thought I had read that the AirPort must be plugged directly into the signal source only in order to work. The ethernet router would not provide wireless access.
I am considering this configuration because I'm considering buying the new LG BD300 BluRay player that features streaming Netflix. The machine needs an ethernet connection to provide this feature.

It should be OK. I have a cable modem connected to a Linksys wired router: this feeds an iMac and and Airport Express, and then an iBook connects wirelessly to the Airport Express.
This all works fine for internet connection - both computers connect to the internet without problems: the only oddity arises with file sharing - the iBook can see the iMac, but the iMac can't see the iBook - possibly because it's effectively on a subnet. I haven't tried to sort this out because working one way is good enough for what I need.
But the basic connection, getting IP numbers etc, works fine.
Of course you could consider replacing the Express with an Extreme - it would be more expensive that a router, but would be a neater way of connecting: it has three outgoing ethernet ports in addition to the wireless and the subnet issue I mentioned wouldn't arise here.

  • Connect Airport Extreme to existing router without ethernet cable

    I am looking to connect my Airport Extreme to an existing router without the use of the ethernet cable.  The existing router is on the ground floor whilst I would like to install the Airport Extreme in the first floor to improve WiFi range on the 1st floor.  I am able to connect Airport Extreme to the router with the ethernet cable (in which case both the devices have to be close to one another on the ground floor) but unable to get Airport Extreme set up without the ethernet cable.  Is it possible to connect Airport Extreme to the existing router on a non-wired basis (i.e. without the ethernet cable) and if yes, how would be I able to do it.  Any help would be appreciated.

    The AirPort Extreme can connect wirelessly.....IF.....your existing router is also another Apple router.
    Is that the case here?  If yes, what model number is your existing Apple router?
    If no, you will need to continue to connect the AirPort Extreme using a wired Ethernet connection.

  • Router connected to cable modem by Ethernet port cannot get IP address from DHCP.

    I have an ethernet cable on Fa0/0 connecting my 1841 router to my cable modem. The issue is that the router cannot obtain an IP address via DHCP when I have the "ACL-OUTSIDE-IN" ACL applied inbound on the Fa0/0 interface. I tried to allow all BOOTP and BOOTPS traffic in my ACL, but still no luck. I really don't want to run the router without a simple ACL firewall and connect it to the internet. When I take off the ACL off of Fa0/0, the router is able to get an IP address via DHCP.

  • How do I use a 2nd Airport Extreme plugged into an Ethernet Wall Plug to join an existing wireless network to give me a better signal upstairs?

    I have a 5th generation Airport Extreme giving me a great wireless signal on the 1st floor of my house. However the signal upstairs is weak. So I purchased another 5th generation Airport Extreme that I would like to plug into an ethernet wall plug upstairs. I would then like to have the upstairs Airport Extreme join the same network thus giving me a good wirelss signal upstairs. I have a MacBook Pro running OS 10.7.4. Can somebody give me step-by-step directions to set up the upstairs Airport Extreme?

    I assume that the new AirPort Extreme is still in its original factory default settings.
    Before you connect the AirPort Extreme, please connect a laptop to the Ethernet cable that will be used for the connection and turn off the wireless on the laptop. Make sure that you can can connect to the Internet before you begin to configure the AirPort Extreme.
    Disconnect the Ethernet cable from the laptop and connect it to the WAN "O" port on the upstairs AirPort Extreme and power it up.
    Open Macintosh HD > Applications > Utilities > AirPort Utility 6.1
    Look in the upper left hand corner of the screen for a tab or box that reads "Other AirPort Base Stations (1)"
    Click on that box,then click on the name AirPort Extreme xxxxxx
    Wait a moment while AirPort Utility analyzes the network and then displays a message that the AirPort Extreme will be configured to extend your existing wireless network.
    Enter a Base Station (device) name for the AirPort Extreme (and a device password if prompted), then click Next.
    Wait another minute or two until AirPort Utility notifies you that the AirPort Extreme has been Set Up.
    That's it.

  • Is the airport extreme just a replacment for your cable modem?

    What exactly is the airport extreme? I been thinking about buying one but I want to know what does it exactly do. Is it a replacement for your cable modem that creates a wireless network?

    No it is not a replacement for your cable modem. Airport Extreme allows you to access the Net wirelessly. Your cable modem gives you your broadband access to the Net, but you have to connect to it via an Ethernet cable (RJ45). If you own a Apple Laptop, like an MacBook you need a wireless connection. Apple’s Airport Extreme gives you this access. Also it comes with the latest wireless speed “n”, verses “g” and “b” before it. In fact it will do all three speeds.
    I have a “b” speed desktop system that is connected via an Ethernet cable, and two laptops that use the new “n” speed and one laptop that is running under the “g” speed. The best part is that you can plug a printer or hard-drive via an USB cable and share it with other computers on you home network. Also it very easy to use. If you don’t have a Laptop there is not much use for this product.

  • Airport Extreme Base Station not cooperating with Cable Modem

    The non-specific issues are by far the most frustrating and I can't make any sense of this. To be fair, this might not be a AEBS issue as much as a ISP issue, but any suggestions are much appreciated.
    History: My setup has worked great for about 6 months, but recently I've been having intermittent problems (described below) that have been getting progressively worse and more frequent. The issues have not changed in relationship to firmware/software updates for the AEBS and airport utility.
    Setup: Cable Modem (Time Warner Kansas City is ISP) --> AEBS (A1143 on the latest firmware) --> periodic wireless connection to imac, macbook pro and 2 iphones. A Time Machine (hard drive) is also connected to the AEBS via USB.
    Symptoms:
    -Intermittent disconnects and slowdowns over wireless
    -Wired connections are completely unaffected.
    -Loss of wireless internet connectivity is consistent through all devices.
    -Time machine is unavailable when the internet is not accessible.
    -During disconnects sometimes the router doesn't even appear, sometimes I can connect but can't reach my time machine or the internet, sometimes it won't accept my password and sometimes it times-out.
    Sounds like the wireless transmitter is going out on the AEBS or something, right? Well, Apple was kind enough to replace my AEBS under warranty to try to solve this problem, but it hasn't gone away.
    Could this be an issue with my ISP not distributing IP address properly or something? I'm not really very savvy with the way all that works.
    Thanks for your help with this mess.

    Its gotta be the surrounding interference issue. I found a macworld article that refers to testing the different channels in the 2.4gHz range and finding some completely unusable (as you mention). If I didn't have a couple iPhones that can't run 5gHz, I'd certainly bump up to that because apparently that's where the performance is!
    Here's a link to the article, although it's mostly a review, though information within is pertinent to our issue.

  • Please help me connect eMac, cable modem, and Airport Extreme Base Station

    I connected Ethernet cord from cable modem to Airport Extreme Base Station and then another Ethernet cord from Airport Extreme Base Station to eMac, but I could not get internet access on my eMac that way. I'm only getting internet access by directly connecting eMac to cable modem. Can someone please help me with a step by step explanation of how to set these 3 machines up so that I can have internet access on both my eMac and, wirelessly, on my new MacBook. Thank you very much in advance.

    jenngee, Welcome to the discussion area!
    Ensure that you power off the cable modem for a minute or so when you switch it to another Ethernet device.
    Ensure that you are connecting the WAN port of the AirPort Extreme base station (AEBS) to the cable modem. The eMac should connect to the LAN port.
    The steps for setting this up can be found in the "Designing AirPort Networks" (direct PDF link) document. Look through that document and try to get it setup. Then return here if you have more questions. Don't forget to post what you tried and the issues you encountered.

  • Airport Extreme Cannot see Live Internet Connection from Cable Modem

    Hi,
    When I run a cable directly from my cable modem to my MacBook everything works fine. In fact, that is how I am connected to the Internet right now.
    However, when I run the same cable into my Airport Extreme (AE) and then connect my MacBook to the AE (wired or wireless), the AE reports a problem connecting to the Internet. This is a new situation as everything has been working fine for months. I have changed nothing in this set-up for it to stop working.
    I can only assume the at the AE is broken: the Internet connection is live, it was working fine for months and then stopped working. Is there anything I should try before I throw the AE in the garbage?
    Thanks in advance.

    Welcome to the discussions!
    It appears as if you may not be aware that cable modems must be completely reset whenever the device that they are connected to changes. The reason for this is that the cable modem "remembers" the device that it has been connected to. In your case, it's "remembering" your computer and looking for it when you plug it in to the AirPort Extreme.
    You need to make your modem "forget" your computer. Here's how:
    o Push the reset button on the modem if there is one on your modem
    o Power the modem down immediately after you push the reset button
    o Pull the battery in the modem if it's easily accessible
    o Leave the modem powered down at least 20-30 minutes (Some ISPs take longer)
    Power down the rest of your network as well.
    After the power down period, start the modem first and let it run 3-4 minutes by itself
    Then start the Airport Extreme (you may need to "hard reset" the device again to start over on the configuration) and let it run a few moments
    Then start your computers one at a time
    Please post back on your progress. Remember, if you need to connect your computer directly to the modem again, you must reset the modem again because it will "remember" the AirPort Extreme if you have reset it correctly.

  • Silly question, maybe. I want to change from Verizon DSL to cable, but cable company doesn't supply router.  can I use my Airport Extreme as wireless router?

    We currently have the following wireless home-network configuration, powered by Verizon DSL. 
    2 macbook pro’s
    1 emachine
    HP PhotoSmart 6122 all-in-one printer
    Apple TV
    Apple Airport Extreme Base Port A 1408
    Westell 7500 router
    Thinking I’d get wider wireless coverage throughout my 2 bedroom home, I purchased the Airport Extreme. It is connected to the router via its sole usb port.  The result was only a tiny increase in speed, and no increase in coverage, so I don’t know why I have it.
    We now want to change from DSL to cable, thus ditching Verizon.  Our new cable provider supplies the cable box, but no router for wireless networking. 
    Here are my questions.
    Can I use the Airport Extreme (AE) as a wireless router? 
    If so, how should I hook it up?  Should the usb cable go from the AE to the cable box, and all the other devices connect wirelessly?
    If not, how should I be using the AE to some advantage?  What can I get out of the investment?
    Thank you very much for your help!  Beatriz

    What I wrote has nothing to do with what the cable company charges for their installation. And, usually they will help with the router setup even if you supply your own router. I don't know what they will charge for the modem.
    Note that you need to get just a modem. You don't want a modem/router combination. That will make using an AEBS effectively nearly impossible. You will need to ask specifically for just a standalone modem, and that you will supply your own router.

  • I have Verizon FiOS service for phone, internet and TV but I only have one TV hooked up for it for just basic cable service with no DVR and no need for widgets.  Can I use an Airport Extreme as my router and not use the FiOs router?

    I want to use an Airport Extreme as my router.  I currently have a Verizon FiOS router.  I have Verizon for phone, internet and TV.  However, TV-wise, I just have a basic service for one TV with just a regular box.  No HD, no DVR.  Don't need access to a menu, widgets, on-demand.  Can I eliminate the FiOS Router and just use the Airport Extreme and still have phone and internet?

    I know that it will increase my wireless coverage in my house but will it increase the speeds?
    Not sure what you are asking here.  The AirPort Extreme is only going to be as fast as the Internet connection that it receives.....which is 75/75. It cannot take a 75/75 connection and make it go any faster.
    If you locate the AirPort Extreme in an area where you need more wireless signal coverage, the AirPort Extreme would deliver 75/75 in that area.  But, keep in mind that the AirPort Extreme must connect to the FIOS router using a permanent, wired Ethernet cable connection.
    If you are asking if the AirPort Extreme can wirelessly connect to the FIOS modem router, and extend the FIOS wireless network, the AirPort Extreme would not be compatible with a FIOS product for that purpose.

  • I have airport extreme 802.11AC as a base that connect to Cable modem. How can I connect D-link DIR-655 to AE to utilize as an extender or repeat?

    Hello-
    I have wireless router Airport Extreme 802.11AC that connect direct to Cable modem...how can I setup the D-Link DIR-655 wireless router to AE and act as extender or repeater?. Thanks in advance.

    Apple has done their best to install proprietary software in their wireless routers that is designed to only allow other Apple routers to repeat or extend the network wirelessly.
    So, the chances are extremely small that a D-Link....or another other router for that matter.....could be configured to do what you ask.
    There are no settings on an AirPort Extreme that would allow a D-Link device to extend the network, so all that you can do is experiment with different settings on the D-Link device to see if it might be possible for it to extend the network.
    A post on a D-Link support forum might be a good idea to see if any D-Link specialists have some ideas on this topic.
    Good luck.

  • I am experiencing network failures with my Airport Extremes: the main router is a 2nd Gen, the extension a 5th Gen. The 5th Gen keeps on losing connection with the main router. Any ideas why?

    I am experiencing network failures with my Airport Extremes: the main router is a 2nd Gen, the extension a 5th Gen.
    The 5th Gen keeps on losing connection with the main router and thus with the internet.
    Any ideas why?

    Is the second Extreme configured to "extend" the network created by the first? If so its position must be such that it has a strong wireless connection to the first Extreme. If it is at the limits of the first one's wireless range its connection will be tenuous. Place them closer together and determine if that makes a difference.

  • How can I set up an Airport Extreme as a router, in conjunction with my AT&T modem/router?

    I am trying to set up an Airport Extreme as my router, and I am currently using an AT&T modem/router combo. I am wondering what would be the easiest way to do this. Any help would be appreciated. Thanks!

    Connect an Ethernet cable from one of the LAN <-> ports on the ATT modem/router to the WAN "O" port on the AirPort Extreme. This cable must remain in place permanently.
    Open Macintosh HD > Applications > Utilities > AirPort Utility on your Mac
    Click on Other WiFi Devices
    Click on AirPort Extreme xxxxx
    The utility will take a moment to analyze the connection, then a screen similar to this will appear with your AirPort Extreme instead of an AirPort Express
    Type in a short simple name that you want to use for the wireless network
    Type in a device name for the AirPort Extreme
    Enter a password that will be used for both the AirPort Extreme and wireless network
    Verify the password
    Click Next
    The utility will setup everything for you. When the message of Setup Complete appears, click Done and close AirPort Utility.
    The AirPort Extreme wireless network is now available.

  • Installing airport extreme after a router

    when connecting an airport extreme to a router (AE after the router), should the wire from the router go into the WAN or LAN port of the AE?

    It won't matter which port you use if you configure the AirPort Extreme in Bridge Mode, which is the correct setting when you have another router ahead of the AirPort Extreme.
    All the ports become LAN ports in Bridge Mode.
    AirPort Utility >  Manual Setup
    Internet icon > Interner Connection tab > Connection Sharing = Off (Bridge Mode)
    Be sure to restart the entire network after you change the Extreme to Bridge Mode.

  • Airport Extreme Base Station Internet Connection issue

    I have a connection question for Airport Extreme Base Station.
    I have Comcast cable broadband. I connect that to a Linksys router for
    use with my Vonage phone, and then from the Linksys router I connect
    via Ethernet to my iMac. I like the direct Ethernet connection for
    performance reasons.
    In order to set up a home network to connect my Tivo's (and eventually
    my PC and printer), I have set up an Airport Extreme Base station and
    connected it to the Linksys router from it's ethernet connection to the
    WAN (cable modem) input on the Extreme.
    I have connected to the Airport network with my iMac, but since I am
    connected to the Internet via Ethernet, I cannot tell if my Airport is
    connected to the Internet so that I can use it for my Tivo. My PC is
    still in storage from a move, so I can't check with that.
    My question: How can I tell if my Airport is connected to the Internet
    without disabling my Ethernet connection on my iMac?
    A few more info points/questions in case it helps answer:
    1) I previously used this Airport to connect this iMac wirelessly.
    2) Should I be connecting it to the LAN port since it's coming out of
    the router?
    3) If the connection issue is because I am going through the Linksys
    first, can I connect the modem to the airport and then use the LAN port
    to connect to the Linksys router?
    4) If I have to disable the ethernet connection to test the Airport,
    how do I do it? Just unplug it?
    I appreciate any help as the online and manual help from Apple is not
    quite up to par with such a complex configuration.
    Regards
    Bill

    2) Should I be connecting it to the LAN port since it's coming out of
    the router?
    No, connecting to the WAN port is fine.
    3) If the connection issue is because I am going through the Linksys
    first, can I connect the modem to the airport and then use the LAN port
    to connect to the Linksys router?
    The issue is that you have two routers which effectively creates two networks. Unless this was your original intent, you will want to setup the AEBS as a bridge.
    To set up the AirPort Extreme Base Station (AEBS) as a bridge, using the AirPort Admin Utility, connect your computer directly (using an Ethernet cable) to the LAN port of the AEBS, and then, make these settings:
    Network tab
    - Distribute IP addresses (unchecked)
    - Apply the new settings.
    - Wait at least 5 minutes.
    4) If I have to disable the ethernet connection to test the Airport,
    how do I do it? Just unplug it?
    Well, that's certainly one way, but an easier way is to temporarily disable the "Built-in Ethernet" in your network configuration.
    System Preferences > Network > Show > Network Port Configurations
    - Built-in Ethernet (unchecked)
