Airport Extreme doesn't see cable modem

A new Airport Extreme refuses to see an Optimum Online cable modem. As for troubleshooting, I've seen the new AE working at an Apple authorized store, bought a brand new ethernet cable, but still only get a blinking yellow light. I can plug my G5 directly into the modem with no problems. Any thoughts?

I had a similar problem once. Turned out Verizon (the ISP) had their DHCP server bind to the MAC address of the first machine connected to it and wouldn't issue a new IP address to another machine (MAC) address, unless you either:
1) let it time out like 45 mins!
2) you spoofed the MAC address of the old device on the new device. (Can't do this on the AEBS, unfortunately.)
3) you connected the old machine and (rather than just disconnect it after it got an address from the DHCP server), you actively released the DHCP address.
Until I found out this vital DHCP server behavior info (after waiting an hour on hold with tech support and then working through level 1 support's noob scripts), I too was playing around with resetting the modem, etc., etc. The problem however was the ISP's DHCP server 'security'.

  • Why does my airport extreme not recognize my cable modem anymore?

    Why does my airport extreme not recognize my cable modem anymore?

    Have you tried resetting the modem? Power it down and let it rest a moment, then power it back up again.
    Also, some ISPs require physically detaching their cable from the modem for it to be fully reset. Literally unscrew it from the modem. Try that, in conjunction with powering it down.
    Don't do anything with your Extreme, other than powering it down too, in the event the modem reset does not help. Reconfiguring it may be necessary but this is not justified quite yet.

    airport extreme doesn't see my hard drive (free agent 500Gb)

    A few things to check are:
    Make sure that the drive is formatted in Mac OS Extended (Journaled) or FAT32. The normal Windows format of NTFS will not work.
    The USB port at the AirPort Exteme is under powered. You almost always need to use a powered USB hub with a drive at this port, even if the drive has its own power supply.

  • Airport Extreme doesn't see ethernet ADSL router

    I'm having a problem trying to connect my new Airport Extreme base station to a one port ethernet conexant adsl router. It simply doesn't see that the router exists.
    The way I have it setup at the moment is the router distributes an IP address to the airport and the airport distrubutes IP addresses to wireless devices. At least that's what's supposed to happen.
    I have an Airport Express connected to the router and that works fine. Connects no problem on its default settings. The Airport Extreme however doesn't connect with its default settings.
    Anyone have any suggestions as to how to fix this problem? Is it possible the Airport Extreme just doesn't work? I've connected the Airport Extreme to my laptop via the WAN port to set it up and that worked Ok so as far as I can tell the WAN port works fine as does connecting wirelessly. The two just don't talk to each other.

    Try the following ...
    Modem/Router Power Recycling - Quick
    o Power-off the ADSL modem, AEBSn, & computer(s); Wait at least 5 minutes.
    o Power-on the ADSL 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 ADSL modem, AEBSn, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
    o Power-on the ADSL modem; Wait at least 15 minutes.
    o Power-on the AEBSn; Wait at least 5 minutes.
    o Power-on the computer(s)

  • My Airport Extreme Disconnects From the Cable MoDem Every Few Minutes

    Hello,
    I start a new topic as my previous title was wrong and there was no suitable answer.
    I have had an Airport Extreme for 3 years and it sometimes disconnects after a few minutes. Actually, it more looks like that the Airport crashes: the "PC Link" light on the cable modem goes off, the Airport lights go off and I cannot find my Airport Network any more on my computer.
    When this happens, I can either unplug it from the power and plug it back in, or simply move the Airport around a little bit, and it will re-start. Sometimes the problem does not re-occur for a few hours or days, sometimes it keeps happening every few minutes and of course drives me crazy...
    Is it because ... :
    - ... my Airport has a faulty connection and I should replace it?
    - ... there are power surges in my electricity installation (eg this seems to happen when I or my neighbors have air conditioners on, I live in one of those old New York buildings with old electricity installations), and I should get an anti-surge device, or a newer Airport would deal with this better?
    - ... of something else? I tried replacing the Ethernet cable between the MoDem and the Airport and it failed, there does not seem to be a source of interference around my place.
    Thanks for your help!

    I have had similar problems. Not as bad as some of you but usually in the morning I discover that I have dropped onto someone elses wireless they are not as fast. Then I have to troop upstairs, unplug the Extreme, replug it and then everything is allright until the next morning. But it is sporadic. It has run fine now for a few days. This problem has persisted now for a year. And yes I have tried resetting it.
    Next month I plan on going to the big city and I am going to take my Extreme to one of Genius' at the Apple Store. I am curious if anybody else has tried that solution and how much it might cost.

  • Airport Extreme doesn't see my USB disk

    Hello,
    i have changed the usb disk (full) that i connected to my airport extreme. I replace it by a new one (MEM UP, 2 To), formatted in mac os extended.
    This new disk is mounted by the Mac but when i connected it on the Airport, the Airport doesn't see it : "no disk detected".
    There isn't hub, it is connected directly.
    Have you got an idea ?
    Thanks,
    Rudy

    The USB port on the AirPort Extreme is under powered....and your new hard drive may require a bit more current than the old one.
    It is always a good idea to use a powered USB hub with the AirPort Extreme whenever you are using a hard drive....even if the hard drive has its own power supply.
    A powered USB hub may not solve your issue, but there is also a chance that it will. Might be worth a try.

  • Using Airport Extreme Base Station with Cable Modem

    Hi everyone,
    I have just bought an Airport Extreme Base Station. I connected it to my cable modem (Surfboard 3100) through the WAN port and my iMac G4 is connected to it through the Ethernet port. Installed the Airport Utility, and configured the base station with the normal settings of DHCP for Internet and DHCP for internal network.
    After restarting the base station, my Internet connection from the iMac through the base station is very slow and most of the time will time-out. My Internet connection through my PowerBook G4 using wireless through the base station is ok though.
    My question is, is there some setting which I should set for the Ethernet portion of the base station to make my wired connections to the Internet work?
    Thanks in advance for any help!
    regards,
    Weiming
    iMac G4   Mac OS X (10.4.10)  

    Hi,
    My iMac G4 does not have an Airport card. I did not physically restarted the base station, its part of the sequence when we update the configuration, that the base station will restart on its own.
    regards,
    Weiming

  • Airport Extreme doesn't see wireless router

    I set up a wireless router for my G5 iMac and have turned airport on. the default SSID is belkin54g which my PC laptop sees and connects to just fine. The strange thing is, on the iMac, it showed up in the list of available networks. At first I got all bars, then it quickly dropped to one and then it completely dropped connection with the router when it was sitting on the same desk. If I create a computer to computer network I get all bars filled but it doesn't connect to the internet. Seems like I'm missing a setting on the iMac since the PC has no trouble. The model is a Belkin 54g 4 port wireless router.
    BTW: This is on 10.4.2 and the latest airport update.
    Any help would be great!!!

    To My knowledge, The airport utility only sees Apple airports. So seeing your 2wire via that app I do not believe works. The program I like is iStumbler. I see all kinds of things in my neighborhood.
    Anyway, I claim Chipset conflict. Back what may be the security down. OR turn it off and work your way up to find what level is needed. After no security, try not broadcasting SSID, after that tweak it until you don't see it and then back off to the one that works. Every one says wireless is wireless. Even in my work place, we cannot get PC's and Mac at the same level on of security on the same access points.
    Bottom line, start fresh, tweak till it works. Because at the apple store, the chipsets are the same, or meant to work well. Why you may ask.... They want you to buy and Apple extreme with all the features.

  • Airport Extreme doesn't recognize USB Drive

    I have a USB external drive that is working fine when attached to my iMac but my airport extreme doesn't see it at all. I have tried resetting the power to both devices.
    AEBS version 7.2.1
    Does the drive have to be formated a certain way for it to work? Right now it is "Mac OS Extended" I have also had it formatted as OS Extended (Journaled). Neither are working.

    Oh well... No dice huh? I just noticed that the Airport Extreme locks up every time I use my sonicwall global VPN client as well per this thread.

    Looks like will have to return this and try the linksys offering.

  • For the new airport extreme what type of cable do I need to connect to my cable modem. Is Cat5 OK or will that bottle neck things?

    For the new airport extreme what type of cable do I need to connect to my cable modem. Is Cat5 OK or will that bottle neck things?

    Assuming that your cable modem has Gigabit Ethernet ports (possible, but it probably does not) Cat 5e or Cct 6 would do the job that you need.
    If the cable modem is using a 10/100 Mbps port, then Cat5 will be OK.

  • Airport Utility doesn't see functioning Airport Extreme Base Station

    I have an Extreme (n) Base Station which serves as a WDS main with one relay Express and one remote Express. All three are functioning properly. Now I want to add a second remote Express paired with the main Extreme. However, Airport Utility doesn't see the Extreme, even when hardwired. So I have no way to add in the Apple ID of the new remote.
    Any suggestions on how to resolve this? Is it necessary to restore default settings on the Extreme and reconfigure EVERYTHING?
    Thanks.

    Not yet. Hoping there is some other approach, since if I reset it and then it loses the connection before configuration is complete, I lose the functions that are working now.

  • Have an Airport hooked up to a Cable modem, gives wireless access to 1 laptop but on to anything else

    I have an Airport hooked up to a Cable modem. Give wireless access to my MAC Book Pro, connects to my Ipad but will not have internet access, tried a different Airport with the same results. Please help.

    Thanks for the info.  We will try a shortcut first and hopefully it will work.
    On the Mac.....
    Open Macintosh HD > Applications > Utilities > AirPort Utility
    Click on the AirPort Express, then click Manual Setup
    Click the Internet icon at the top of the AirPort Utility window
    Click the Internet Connection tab just below the Internet icon
    Make sure that the setting for Connection Sharing is set to Share a public IP address
    Click Update at the lower right and wait a minute for the AirPort to restart
    Now power off both the cable modem and the AirPort Express
    Wait 10 minutes. Longer will not hurt at all
    Power up the modem first, and let it run for 5 minutes by itself
    Then power up the AirPort Express
    Check to see if multiple devices can now connect

  • Wifi signal from Airport Extreme doesn't reach all areas of my house.  Is there a way to extend it without sacrificing bandwidth?  Airport Extreme version 7.6.1

    The wifi signal from my Airport Extreme doesn't reach all areas of my house.  Is there a way to extend it without sacrificing bandwidth?  I have an Airport Extreme running version 7.6.1.

    You will need to add another device like an AirPort Extreme to provide additional wireless coverage in the house.
    The only way to preserve bandwidth on a network would be to connect the two AirPort Extremes using an Ethernet cable connection.
    While you can "extend" using wireless only, typically half of the bandwidth on the network is sacrificed when you do this.

  • No Internet via Airport Extreme and Speedtouch Ethernet DSL modem

    I've recently purchased a McBook pro and wanted to create a wireless network. I have a new Airport Extreme Base Station and have successfully set that up, but with no internet connection!
    I can get a perfect connection by hardwiring either of my machines to the DSL Modem directly (via Ethernet cable), but when i connect the Airport Extreme to the DSL Modem via ethernet there is no internet.
    After a bit of research i'm wondering if there is a "bridge" issue... though i have no idea what that means or how to resolve it. Can anyone help?
    Details:
    Airport Extreme 802.11n
    Speedtouch DSL Modem (Thomson ST510 v6)
    G5 Power PC Tower (10.4.11) will connect to the Airport Extreme via ethernet, currently connects to the DSL modem via ethernet.
    MacBook Pro (10.6.4) will connect wirelessly. can currently connect to the internet through the DSL modem via ethernet.
    Dynamic IP via ISP connection via PPPoa

    Hi Steven, I know this question has been answered and is a couple of months old but I think you may be able to help with my set up? I have a Thomson speedtouch 510 v6 modem router provided by Karoo (UK). My other Belkin N modem router has just bust [again] so the Speedtouch is my old faithful backup device. Now, i've never been able to get on ichat with the Belkin as its a mimo n speed and this is apparently not compatible; So i'm now on ethernet with the st510 and have just set up ports for ichat thanks to a thread called http://discussions.apple.com/thread.jspa?messageID=2719419&#2719419.
    What I want to know from you (because I really need a wireless router to get me off this ethernet support system and back on airport) is how you're getting on with the st510 / airport extreme combo now and can you use ichat on it? If so does your connection doctor say full cone in network settings or something else? As I say, I really want to use ichat and have never been able to in 3 years of owning my Macbook Pro. Hope to hear back from you Steven. Regards Steph

  • Can I extend my network by connecting one of my airport express devices to my airport extreme via an ethernet cable? I have CAT5 cable throughout my house but have a wireless network w/ 3 airport expresses

    Can I extend my wireless network by connecting one of my airport express devices to my airport extreme via an ethernet cable?  I have a wireless network with 3 airport expresses and 1 airport extreme functioning as the base station. I have CAT5 throughout my house.

    Welcome to the discussions, mib88!
    Can I extend the network a second time with another Airport Express...
    The short answer would be no. If you want more details, please continue to the next paragraph.
    Apple's "extend a wireless network" works just like the hub and spokes of a wheel. Your main hub is either the Time Capsule or the AirPort Extreme and the AirPort Express is at the end of a spoke. You can add more devices at the ends of other spokes, but these devices will communicate directly to the hub, not to another device at the end of a spoke.
    Apple does offer an option which is is known as a "static WDS", which can consist of a "main", "relay" and "remote" device. The problem here is that this type of setup has two huge drawbacks:
    1) All of your faster "n" devices will drop down to much slower "g" speeds
    2) The bandwidth or speed capability on the network will drop down to only 25% of the original bandwidth with a "main", "relay" and "remote" on the network.
    Don't think you want this on your network. Your best option is to connect the new AirPort Express to the "hub" using an ethernet connection. If you can't run the ethernet cable, take a look at a pair of ethernet powerline adapters to accomplish the same task by sending the ethernet signal over the AC powerline in your home.
