  • Airport extreme working on some devices but not others

    All of a sudden airport extreme has stopped working on some of our devices.  within our family we have an old macbook pro running tiger, a 2nd gen macbook air running snow leopord, a black macbook running lion, a mac mini running lion, two iphone 4s and an iphone 3g.  the wireless only works on the two computers running lion.  nobody has changed any of the settings on the airport extreme.  it is running the latest version and has been working fine up until a couple of days ago.  i have reset the modem and router several times each but nothing has helped.  when we try to connect the iphones to the wireless they say unable to join network and the computers running snow leopord or older say there was a problem connecting to the network or something similar to that.  any help would be appreciated!

    I know that you have reset both the modem and AirPort already, but I would recommend that you do the following as a minimum:
    Power-down the modem, AirPort base station, and computer(s).
    (OPTIONAL, but recommended) While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
    After the base station resets, go ahead and power it back down.
    Power-up the modem; wait at least 10-15 minutes.
    Power-up the base station; wait at least 5-10 minutes.
    Power-up your computer(s).
    In this basic configuration, computers connected to the base station, either by wire or wireless (as appropriate for the base station type), should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options.

  • HT1218 Airport Extreme base station is working, but not visible on network?

    My Airport Extreme base station is working:  all devices are able to connect to the internet, but Airport Utility shows no connection.  Only one computer even shows the device-- greyed out-- saying "Device not Found."  The airport utility shows version 6.2;  OS X version 10.8.3.  How do I update the base station to version 7 if the device can't be found?  And how do the devices connect to the internet without "seeing" the device? 

    Thanks for checking. This model should be visible in AirPort Utility in Mountain Lion.
    If you have not already done so, I suggest that you perform a complete power cycle on the entire network as folllows:
    Power off every network device....in any order you want
    Wait a minute or two
    Start the modem first, and let it run a few minutes by itself
    Start the AirPort Extreme next, the same way
    Continue starting devices one at a time about a minute apart until everything is powered back up
    Check the network again using AirPort Utility
    You can also temporarily connect an Ethernet cable from your Mac to one of the LAN <-> ports on the AirPort Extreme to see if a connection is established that way.
    If still no luck, try another Mac if you one handy. After that, all that I can suggest is that you perform a Factory Default Reset on the AirPort Extreme and configure it again.

  • How can I utilize a 2nd Airport Extreme to extend a network but not WIFI, only hardwired?

    Hi All.  Need your help figuring this out.  The location of the cable line in my home causes a bit of an issue for my internet dependant electronics.  My computers have no problem connecting over Wifi but certain peripherals require an ethernet connection as Wifi is not an option for them.  I have prepared this quick diagram to explain my perfect set up.  I have a current gen Airport Extreme and a Previous gen as well.  How can I set my 2nd Airport to receive the Wifi from my main airport, but then only serve as a router, not extend the WIRELESS network.  Only provide a hardwired network.  In other words, I know how to "extend network" with airport utility, but then the 2nd airport also casts its own wifi network and causes problems.  I only want the one single Wifi network.  The 2nd router should only be providing ethernet connectivity.
    Is this even possible?  Both Airports are running the most updated firmware.  Any advice would be greatly appreciated!!!

    With a properly configured extended network both AirPorts will be broadcasting the "same" Wi-Fi network. This shouldn't impact wired clients at all. The other advantage of using an extended network is that your older AirPort Extreme's Ethernet ports will be enabled for wired clients.
    At present the only other option would be to connect the older Extreme to the newer one using an Ethernet connection between them. Then disable the older Extreme's Wi-Fi radios.

  • AirPort Extreme works with my Mac, but not my PSP?

    Just got a new AirPort Extreme today, and I had difficulty setting up because i had typed something wrong. I fixed it and was excited to see that my homepage appeared on my computer, then I tired connecting with my PSP, and it found the signal then gave me a message that that it couldn't connect with the IP. The type of encryption was supported, and the code for the security was correct, but I still cannot figure out why it won't work.
    I successfully hooked up the signal, not the ethernet, through the Mac OS X system, and the Windows Vista Ultimate system which is installed through Bootcamp. I cannot figure out why, though, that the PSP won't connect.
    Please help or explain what I might be doing wrong!!!!

    On your Mac, open the Airport Utility.
    Select the airport base station from the list, go to manual setup.
    From menu select, Base Station > Equivalent Network Password
    Now copy copy password onto the Windoz PC.

  • Airport extreme drops out on imac, but not on powerbook....

    Hi
    Here's what i have running.
    A 4 year old powerbook which always connects just fine to the internet, with no dropping of the signal.
    A new imac with a airport extreme built in. It regularly just drops the internet connection, even though the internet is seen perfectly by the other machine.
    Router is a standard netgear router virgin media provide.
    Periodically, and some days it will be totally fine, but mostly on the weekends (like now) the signal on the imac just drops out (from perfect 4 bars, to none) and i lose access to the internet on this machine (very annoying when you are trying to talk to someone on skype!). after some time it reappears, only to drop out again.
    I have reset the modem to automatically select a wireless channel, but that seems to have done nothing. So following the advise on other chats here, i set the channel to 10. However the problem remains. I thought, well, maybe its the wireless phone, or the microwave, but these do not seem to affect the internet connection to the powerbook g4. The software updater for the "airport utility" claims it is up to date.
    And now i am totally lost as to what to do! Any suggestions? Thanks

    I have this very same issue. Reproducable on 2 laptops (ibook and powerbook), both 10.4.3, to 2 separate ftp servers.
    Transmit fails as well.
    Fetch, however, seems to work just fine. Does Fetch not use the underlying ftp command line app?
    Transferring small files (under 1k) seems to work though.
    The message I get is as follows:
    421 Service not available, remote server timed out. Connection closed
    Timesout for 10-20 seconds, then I get the message. Setting the transfer mode to "binary" manually seems to correct the issue. But this won't work for what I'm doing (Dreamweaver, which must use the command line ftp?).
    Attempting to ftp the same files from my local Solaris and Linux servers seems to work just fine.
    sftp works.
    Apple? Is ftp broken?

  • Airport express 802.11 solid green but not working

    My airport express has been working for several months but will not now.
    I bought it to extend our internet to the upstairs as it was too far from out
    internet location.
    I have restarted it and moved to different outlets upstairs, but it will not work.
    It goes through all the proper color changes and is solid green now. I can stand next
    to it and there is no connection.

    Did you happen to firmware update the main router?? That seems to cause the issue. Or even the express will cause it.. there is a new firmware just hit the web.. 7.6.4 so if you vaguely remember doing it .. or see the main router is now running 7.6.4.. that is why.
    Reset everything to factory and start over.. that is the best way to get things running again.

    Even if the update didn't go through.. still do the factory reset and reconfigure.. it will all come good.

  • I have both a simultaneous dual band and a regular dual band airport extreme on an extended network will the 5ghz work at its full potential if its the one that is extending the network?

    I have a A1143 model Airport extreme with dual band capabilities but not simultaneous, i'd like that to run on the 2.4ghz band, while i have a A1408 model airport extreme as the "extender" but i want to make sure that even though im running the 2.4 and the newer model is extendeding it, my simulataneous dual band will still work to its full potential (ie: 300mbs i think is the max for the 5ghz)..?
    notes: no i can't use the newer model as the primary and the older model as the extender.

    I am assuming that your simultaneously dual-band Extreme is using the same Network Name for both radios. If that is the case, and depending on the distance between AirPorts, the extending Extreme is most likely just extending the 2.4 GHz radio. That would leave the 5 GHz wireless network basically "untouched."

  • HT1145 The airport extreme used with my iMac is not seeing my other devices...anybody, please?

    The airport extreme used with my iMac is not seeing my iPhone 5, iPad (third generation) or my windows based PC.  When I open the airport utility it shows only the internet and my iMac.  It does not identify the others.  Any thoughts?  Thanks

    Hi DaileyT,
    Thanks for using Apple Support Communities.
    For more information on this, take a look at this article:
    When do Apple wireless devices appear in AirPort Utility?
    http://support.apple.com/kb/HT3624
    Troubleshooting missing devices
    If your Apple wireless device doesn't show up in the wireless device list, try the following:
    Check to see that the device is turned on.
    Check that the device is connected to the network via Ethernet or in wireless range of your computer.
    Make sure the device has had adequate time to start up and become discoverable. In the case of Apple wireless devices that are not connected via Ethernet, AirPort Utility scans for new devices once every 15 seconds. From the time a device becomes discoverable (typically around one minute), it could take up to another 15 seconds before the device is displayed in the list.
    If you have just configured a new Apple Wireless device, upgraded the firmware, selected "Restore Default Settings..." or have hard reset and configured an Apple wireless device and it does not show up in AirPort Utility after restarting, you may have an incorrect setting. You may want to hard reset the unit and set it up again.
    If you are connected to a specific wireless network, all Apple wireless devices which make up that network will appear. However, if you "Restore Default Settings..." from AirPort Utility, or hard reset a device that is out of physical wireless range of the computer, you will need to move the device closer the computer to configure it again.
    Best of luck,
    Mario

  • Airport Extreme's support for streaming video NOT reliable for RealPlayer

    AIRPORT EXTREME BASE STATIONS DO NOT RELIABLY PROVIDE STREAMING SUPPORT USING NORMAL TRANSPORTS FOR REALPLAYER.
    Based on a problem I've had for a long time and information provided in RealPlayer OnLine Help, it appears that the Airport Extreme Base Stations do not reliably provide streaming support using normal transports for RealPlayer.
    HERE'S THE REASON FOR CONCLUDING THAT
    Even after updating with the latest software and firmware available for my Airport Extreme Base Station, RealPlayer will not play streaming video when my iMac is online via my Airport Extreme Base Station.
    (The configuration is iMac (non-wireless) --> Ethernet cable --> Airport Extreme Base Station --> DSL modem.
    Note that with that configuration I can browse the internet and play audio through RealPlayer - even though I cannot play streaming video.
    In contrast, when my iMac is connected directly to my DSL modem via an Ethernet cable, then I have no trouble playing streaming video in RealPlayer.
    HERE'S THE "WORK AROUND" SOLUTION I'M USING
    In RealPlayer/Preferences/Transport, I selected to use HTTP transport exclusively.
    Here's where to find details of that solution in RealPlayer's OnLine Help:
    In RealPlayer's Help menu, choose RealPlayer Online Help. Scroll down the left side of RealPlayer's help window to find the section Troubleshooting -> Network/Connectivity -> Wireless Issues.

  • Airport extreme connects to router fine, but express doesn't

    Hi,
    So here is my setup:
    Router -> Ethernet cable -> Airport Extreme = Wifi
    This works absolutely fine. My problem is that I use an airport express to boost the extreme signal, and it's not working.
    I get two errors, "Internet connection" and "No DNS Servers".
    But after reading up on this, people are saying it's a problem with the communication between the express and the router.
    But the airport extreme is communicating perfeclty fine with the router.
    Any ideas would be very helpful,
    Thanks

    Welcome to Apple Discussions!
    I probably can't help much, but I have occasionally had the same problem. You might try going to System Preferences>Network and look at your Airport connection. See if the diagnostics can help.
    Good luck!

  • New Airport Extreme: no LAN lights, base station not found

    I just brought home a new Airport Extreme base station 802.11n to replace a Linksys router which I used without too much trouble (it used to boot me off occasionally, which was annoying). I want to connect to my DSL internet using an ethernet cable. There's also a PC and a Mac in the house that are wireless. However, the Airport Utility doesn't see the AEBS, I've got the classic flashing amber light, and at the back, the WAN light shows a connection to my DSL modem, but I've got no lights on my LAN ports. (I have seen them light up very briefly but they never stay on.)
    I've tried resetting the modem and the base station countless times. I've reconfigured using different ethernet cables. I've disconnected the base station for over 30 minutes before powering up again. I can get a connection when I connect my modem directly to the mini. I've tried using different LAN ports to connect the base station to the computer.
    What should I try next? It's a really simple setup, and all I'm trying to do is to connect to the internet.
    Thanks for any suggestions.

    I know you have tried a series of resets, but please try the following with your Mac Mini connected directly, using an Ethernet cable, to one of the LAN ports of your 802.11n AirPort Extreme Base Station (AEBSn), and the AEBSn's WAN port connected (via Ethernet) to the DSL modem.
    Try the following, in order, until the Mac Mini is able to access the Internet:
    1. If the modem has a reset switch, use it to reset the modem. Wait at least 5-10 minutes for the modem to initialize.
    2. Remove power from the modem. If it has a backup battery, remove this as well. Wait 5-10 minutes. Replace the battery, and add power back to the modem.
    3. Perform a complete power recycle of your network components as follows:
    Modem/Router Power Recycling - Quick
    o Power-off the modem, AEBSn, & computer(s); Wait at least 5 minutes.
    o Power-on the modem; Wait at least 5 minutes.
    o Power-on the AEBSn; Wait at least 5 minutes.
    o Power-on the computer(s)
    If this fails to get the modem to "recognize" the Internet router, then try the "Full" version.
    Modem/Router Power ReCycling - Full
    o Power-off the modem, AEBSn, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
    o Power-on the modem; Wait at least 15 minutes.
    o Power-on the AEBSn; Wait at least 5 minutes.
    o Power-on the computer(s)
    4. Contact your ISP to have them perform a "modem reset."

  • Airport Extreme with iPod Touch?  But 2 floors of concrete & Brick Walls??

    Qwik-Question: Can Airport Extreme penetrate brick and 2 floors of thick concrete to reach my iPod Touch on the upper floor??
    _FULL DETAILS:_
    Hello! I have been using Macs since 1989 and should be a pro by now-- but things have advanced so much that...
    ...that I use Apple Discussions regularly!
    +OK I have a wired ethernet with a cable modem going to a D-Link Router, going to a switch with a MacBook, G4733 and PBG4-12" (i.e. PB-Helium!)(Loveit) plus 2 ethernet printers-- in my basement office, then nothing on the "ground" floor, but another "switch" on the next floor above (in the US this would be the second floor; but in Europe it would be #1, with Ground Floor "0" and basement "-1").+ On the upper floor is an iMac (2005) and cables to attach other Macs/PC's as needed.
    Primarily I want WIRELESS so that my iPod Touch with the January 2008 software update is able to access the www for eM and weather and stocks etc. I've tried this via borrowing a neighbor's WiFi (with his permission) last week-- worked fine! (His PC wireless was located on an upper floor, not the basement!)
    Other reasons for going wireless-- (i)using my PB or MB on the "ground" floor (no cable there); and (ii)when my daughter visits-- with her VISTA PC (although we've had problems when she uses a cable in my home network-- VISTA kicks-out the Macs after a while and I have to re-initialize the D-Link Router!!!)
    (NOTE: I plan to keep my printers and the current MB / PB / G4733 primarily on the wired network - I assume I can do this, i.e. have both wired and wireless and choose which I want when I want it?)
    _AND NOW THE KEY QUESTION IS:_ *WILL THE 2 LAYERS OF CONCRETE AND BRICK IN THIS BELGIAN HOUSE ATTENUATE THE SIGNAL SO MUCH THAT I CANNOT USE WIFI WITH THE ITOUCH FROM THE TOP FLOOR??*
    And if so, what is the best solution?
    1. Just install an Apple Extreme in basement and pray?
    2. Somehow attache the Apple Extreme to the upstairs switch (is that possible??)
    3. Someone said that an "airport" may be better for this than an Apple Extreme? Why??
    4. Other-- a repeater i.e. Apple Extreme in basement with a "repeater" somewhere (ground floor?)
    I really am not sure-- and would be disappointed if I spent $200 (is that the price? Likely more in Europe in Euros!) for an Apple Extreme in the basement and then find the signal is not available on the top floor...
    Thanks for any comments, references etc.
    Best regards,

  • Bonjour/Airport Extreme only for Wake On Demand, not for Wireless Network

    Hi, I'm trying to set up Wake On Demand for my tower (Mac Pro 2009) with an AirPort Extreme (802.11n) but I don't know anything about IPs and servers.
    I *don't want a wireless* network, just to be able to wake my tower up with a MacBook when on the road.
    I have put the AirPort on an existing LAN-Network and then connected the MacPro to the AirPort. I can go online and I get no errors from the AirPort Utility (latest FirmWare). In *System Preferences* > *Energy Saver* I have turned on *Wake for Ethernet network access*.
    Is the Setup complete? Is Bonjour enabled?
    How do I access it from my MacBook? Sorry to ask such basic questions but I can't find a solution on this page:

  • HT4259 I have my airport extreme plugged in within range but the device does NOT appear in airport utility (on the left).  Please advise.

    To extend wifi range, I plugged in my airport extreme within exisitng range but the device does not appear in my airport utility (on the left of the screen).  The airport extreme is blinking amber.  Please advise. Thank you.

    The AirPort Extreme can extend the signal from another Apple router wirelessly, so as long as you have a 802.11n version of the products, the extend function should work.
    Please check to locate the Model No of both of your AirPort routers. It will be on the bottom of the device. Starts with an "A" followed by four numbers, as in "A x x x x".
    Post back with that info.
    We also need to know the version of AirPort Utility that you are using. If you are not sure, click the AirPort Utility menu in the upper left corner of the screen, then click About AirPort Utility and post back with tht info as well.
