Non-acknowledgement of plugged in Ethernet Cable

Greetings!
This evening, when plugging in my laptop to the LAN network at my work, I encountered a problem that I am afraid may be signaling the need for expensive repair. Although I plugged in a working Ethernet cable (I verified on this computer!), the laptop's network status insisted that the cable for Built-In Ethernet was not plugged in. Is this a hardware failure?

Not necessarily. That is a catch-all description roughly equivalent to "It ain't workin' at all".
Exactly which powerBook makes a difference -- older ones require the correct cable (straight or cross) before they can function. The far more common straight cable has the same-colored wires in the same order at each end of the cable. Look through the clear connector body at the tiny wires inside.
There are also many configuration problems which could give you that result. Many corporate set-ups are using DHCP, so your System Preferences > Network > Built-In Ethernet must be configured to use that.
An IP Address must have been assigned, either automatically through DHCP, or manually. 192.168.xxx.yyy is the "self-assigned" IP Address range, which indicates you are talking only to yourself.

  • System froze when I plugged in ethernet cable, was this the cause?

    I had wifi on when using the net, and then I plugged the ethernet adaptor into the thunderbolt port and plugged the ethernet cable into the adaptor, the system froze, the mouse or pad wouldnt work, so I forced shutdown,
    was plugging in ethernet the cause of the system freeze? Should I have turned off wifi prior to plugging in ethernet?
    Or should I not plug in ethernet while the laptop is on?

    System.log  -- I'm using Lion, not Mountain Lion, but for me, one opens the Console application (in the Utilities folder) and look along the left side panel for system.log.
    Also in the Console application you can look at DIagnostic and Usage Messages and also at All Messages. You'll be looking for something that sounds like a problem at the exact time that your freeze occured.
    I've been doing this "hot plugging and unplugging" of the ethernet cables for years with several Mac laptops going through 10.6 and 10.7 (probably have done this a few thousand times) and have never actually experienced any issues while doing it. The area where I have seen some issues is with the laptops sleeping and not waking up properly, once in a while this has happened, but that's not related to what you had happen. Again, I was using 10.6 and am now on Lion (10.7) [employer hasn't upgraded us all to Mountain Lion, although that will happen shortly], so 10.8 might be a little different.

  • How do I connect my MacBook Pro to my Network using Ethernet as there is nowhere to plug the Ethernet cable in? What adaptor do I need? then how do I keep everything, docs and emails, synchronised daily?

    I have just bought a MacBook Pro and want to synchronise all data (excluding photos and music) and emails currently on my desktop iMac.
    First question, how to I plug in an Ethernet cable to the MacBook so that the two can be connected to the same network via the ethernet? Step one of the Apple setup wizard has me flummoxed!
    Second question, once I have that sorted, how do I keep the two devices synchronised (data files and email) and how do I keep the email synchronised to my iPhone?
    Help!

  • Can only get XBOX 360 to work by unplugging and then plugging in ethernet cable?

    I have 2 desktop computers, 1 laptop computer and 1 Xbox 360 using this WRT54GS ver 6 router.  The desktops and the xbox are wired and the laptop is wireless.  I replaced my old linksys router which I never had a problem with for this one.  If my desktop computer is turned off and I turn on my XBOX, the router does not recognize the Xbox.  I mean the XBOX is plugged into port 3 and that light does not flash on the router.  Now, if I turn on my computer and then turn on my xbox, it still doesn't work.  If I turn on my computer, turn on my XBOX and then unplug the xbox ethernet cable from the back of the router and then plug it back in, then the router recognizes it and it works great.  I have had 2 chat sessions and I phone session with linksys and they cannot figure it out.  They had me go into my xbox and set a static IP address, gateway and DNS.  Then she had me go into forward a few ports on the router.  I never had to do any of this stuff with the old router by the way.  The last guy I talked to on the phone said I need to figure out a way to turn off "MAC Address cloning" in the xbox.  I checked  and there is no way to do this, so I think he is wrong about this.  Does anyone have ANY ideas as to why this problem is happening? 

    I had the same problem and I just typed my settings in manually on my xbox 360's network settings.(IP, and DNS).

  • Problem with earphone when plug in Ethernet cable!!!

    Hi guys, I bought the macbook pro 15 couple days ago. And I realize that whenever I use my Ethernet cable, my earphone has strange sound, so I unplug the earphone and plug it back, it's ok, but after few minutes (when I play a song) I hear that sound again. It doesn't happen when I use wifi (ethernet cable isn't plug in) and I also check it with another earphones but it's just like the first one . I just wonder if anyone have the same problem? Should I bring it to Apple? Thanks all.

    I do not understand. Without third-part programs, the iPod will show up as a camera for get photos and videos off the iPod and it will show in iTunes for file transfer/syncing.
    For photos/videos, the iPod shows up in My Computer and you see the photos/videos in the DCIM folder

  • Will plugging an ethernet cable from a powerline adapter into my Airport Express improve the signal strength that it re-sends as WiFi?

    I have a Airport Express (older style that plugs into the power socket) up one end of the house, which gets the signal from an AirPort Extreme at the front of the house.  It works ok for general internet and email, but the signal at the Airport Express end is not really strong enough for my Apple TV.  So today I bought an Edimax Powerline Adapter.  Connected one end to the AirPort Extreme and the other end to the Apple TV and Apple TV now works great!  So I was thinking, if I connected my Airport Express to the Powerline Adapter with an ethernet cable, would that improve the strength of the signal that the Airport Express would re-send out for WiFi.  But all that happens is that neither the AirPort Extreme or the Airport Express now seem to broadcast any WiFi signal.  Is it possible to do this?

    Yes, but you need to change the mode of the Express from wireless extend to create a wireless network and the routing part to bridge. Otherwise it will indeed mess up.

  • What port to you plug the Ethernet cable to on the router

    What port do yo plug the Ethernet cabe in on the router. I know it is the wan on time capsule.  is it the Ethernet port on the router I don't have a wan on the router
    Thanks

    Thanks
    You pretty well answered your own question.. if the router hsa no WAN ethernet.. being a cable or adsl modem router I suppose then you clearly plug the TC into its LAN port.
    All routers must have WAN port but in the case of the above examples it is a coax cable or phone port.
    A general use router without a modem will have WAN port that is ethernet..
    It is pretty easy to select which to use.. just think direction.. WAN always points to internet.. LAN always points to clients.

  • Can I connect a 5th gen extreme as a bridge/repeater to a non-apple router without an ethernet cable connection?  How?

    I currently have a motorola surfboard cable modem/router (dual N) that works for all our wireless devices (PCs and MACBOOK) except that our ipad 2 which drops video streaming in the livingroom (works great in the office and bedroom).  I'm hoping to purchase a new 5th gen airport extreme and set it up in the living room for the ipad 2 as a repeater/bridge (I think that is the same function) but don't want to have a ethernet cable connecting the motorola to the airport extreme.  Is it possible?  How?  Since the ipad 2 works in other rooms, I don't think it is the ipad 2.

    Sorry, but Apple products would not be compatible with your Motorola modem/router using wireless only.
    If you need to do this using wireless only, you might want to check with your Internet service provider to see if they have a Motorola product that would be compatible for the purpose that you need.
    If you are able to permanently connect the AirPort Extreme to the Motorola modem/router using a wired Ethernet connection, the AirPort Extreme could be configured to provide more wireless coverage that way.

  • Every time I plug an ethernet cable in my MacBook Air, my computer starts immediately. Why?

    I'm using the Thunderbold adapter with the ethernet cable. As well, when it restarts I get taken to a white page that says "Your computer has restarted because a problem has occurred." My computer ALWAYS restarts immediately and very abruptly. What's wrong?
    Thanks in advance.

    That should definitely not happen. The cause may be a defective Thunderbolt adapter. If you don't have another Mac with which to test it, exchange it for another. If an Apple Store is convenient for you, bring both the adapter and the Mac to them and have them determine what the problem is.

  • I travel a lot with work.  Can I plug an Ethernet cable from a hotel room in to this, and then use my IPad or IPhone ?

    Is it possible to use Airport Express in hotel rooms ?  Plugging in the hotel cable to AE, then accessing the access page / page where I enter card details if chargeable on my iPad

    In most cases, this will work just fine. Connect the Express to the Ethernet port at the hotel and power it up. Log on to your private wireless network, and open your browser. The hotel log in page will appear so that you can agree to terms and pay the fees, etc.
    The challenge here, at least in the U.S. is finding hotels that still provide an Ethernet port in the rooms since a majority have already moved to wireless. Ethernet ports are more common if you are traveling internationally.

  • I already have a router and I'd like to use Time Capsule just for its hard drive capacity right now. Is this possible? It keeps asking me to plug an ethernet cable into it.

    So I live with 3 others who already had a router running. So for ease Id like to use this device as purely an external hard drive and occasionally back-up my files and store photos/video etc. Is it possible to use this device strictly for that or do I need to constantly give it an internet connection and back-up over wifi that way...?

    Suggest that you consider the option to configure the Time Capsule to "join" the existing wireless network there and backup over the wireless. The Time Capsule functions simply as a wireless hard drive in this type of configuration.
    Open AirPort Utility and click Continue to to follow the guided setup to configure the Time Capsule.  Select the "Join a current network" option when it appears and then choose the option to have the Time Capsule "wirelessly join the network" on the next configuration page.
    Continue to follow the prompts to complete the configuration.

  • Snow Leopard: I can't login when ethernet cable is plugged in.

    I have a Aluminum 2007 iMac running Snow Leopard. When I try and boot it with all the cables plugged in (Keyboard, External Harddrive, Speakers, Ethernet, Second Display), it will bring up the login screen but then when I try and login, it will just hang at the default Snow Leopard Aurora Wallpaper. It shows the cursor but doesn't load the Finder or anything else. After leaving it be for a few mins, I restarted it a few times and it did the same thing. I have Archived and Installed a few times so far and that didn't fix it.
    When I tried unplugging all the cables, it booted properly and works like a charm. When I plugged the Ethernet Cable in and booted it, it freezes like it used to. I tried plugging in other things and they work. But when the ethernet cable is plugged in at Startup, it will freeze at the default wallpaper (Located in System/Library/CoreServices/DefaultDesktop.jpg).
    When I have the ethernet cable it will boot into Safe Boot.
    Then when I booted it up without the ethernet cable it brought up two alert windows saying that Insecure Startup Item disabled. It says that /Library/StartupItems/tap and /Library/StartupItems/tun have can't be started because they don't have proper security settings. I looked them up and they appear to be Virtual Networking Interfaces (probably installed when I installed Parallels 4.0). Removing them and restarting with the ethernet cable in still has the same affect as before (freezing).
    Anyone have any idea the ethernet cable is causing this to not login correctly.
    Additional Information:
    iMac
    1TB HDD
    3GB RAM

    I suspect that it's busy trying to mount a network file system of some type.
    Are there any errors in your logs that seem appropriate (viewable via Applications->Utilities->Console?)

  • Says ethernet cable not plugged in when it is?

    Hi,
    This is my first time using this discussion board, but I have a question that has puzzled me and my technical help department at my school.
    My computer [a macbok] is connected to the internet [from the computer to a phone jack in the wall] with an ethernet cable. Its been working fine for almost a week, but randomly stopped working last night. After lots of testing, the problem is quite obviously with my computer, which is brand new!
    Whenever I plug my ethernet cable in, the network menu under system preferences tells me "The cable for Built-in Ethernet is not plugged in". I have just discovered that it occasionally works if I manually hold the cable in the plug in the computer and press down hard.
    Is there some way that something could be stuck in the ethernet plug-in thing on my computer that could be preventing it from connecting to the cable like it used to? Does anyone have any idea how to fix this? My computer is still under warranty, but I am currently living in another country from home, so it would be a pain to have to get a new one or get mine fixed!
    Thanks,
    Mary.

    couple of things to try before you call tech support or go to an apple store... sounds like the connection between the ethernet cable and your macbook is faulty. this could be a hardware problem with the macbook, but it could also be a faulty ethernet cable. the ethernet jack could be failing.
    try using someone else's ethernet cable and seeing if this connection problem persists.
    also, look inside the ethernet jack on your macbook. there should be 8 small copper contact points. these should be parallel. if one is bent or they don't look parallel, then that would make the connection unstable/faulty.
    good luck!

  • HT3728 Ethernet cable ran to iMac works, but doesn't when plugged into TimeCapsule

       Need help!!!    Time Capsule will not work.  Continue to get the blinking amber light, even after a soft and hard reset.  I tried to reset the modem and that did nothing to help the problem.  I then plugged the ethernet cable into computer and it works fine (thus how I am online posting this). 
       Any help or suggestions please let me know.
    Thanks

    I guess you are using cable modem..??
    You cannot change over clients without turning off the modem for a length of time that allows the ISP equipment to reset the MAC address of the device that captures the IP.
    It can sometimes take, 15min off or even overnight for the modem to reset.
    When it turns back on.. you must have only the TC connected to it.. the first device turned on will capture the IP.
    So make sure the TC is plugged into modem.. it must be from WAN port.. (next to USB).
    Power up the modem after the off time.. then after 2min power up the TC.
    If your modem is not cable tell us.
    If this doesn't work tell us precisely the modem make and model, and your ISP.

  • AirPort & Internet Ethernet-cable 'smart' TV

    There are similar questions on this topic, but some old and some unclear. So...my question is:
    If I plug in my modem into Airport Express, can I plug in Ethernet cable from 'smart TV" and it would work  getting Netflicks, Pandora radio, etc.
    (Using the WAN and LAN ports)
    I'm considering purchasing the AirPort Express Base Station for this purpose.
    Note; My 'smart TV' also has wifi, if that's the only way it will work, but I figure Ethernet cable would be faster and more reliable.  (Right?)
    These are the only two things I want to connect: Modem for computer (so I can get wifi) and Internet TV thru Ethernet cable.
    My  Internet speed is 50Mbps....so it seems like Airport Express would be all the speed I need. No?

    TP-Link....I don't know. But I have learned that Apple products (software and hardware) tend to work well together, better than mixing brands (Although I use non-Apple keyboards...but that's a simple thing.).
    Well, it's great this should work out. So I plug the DOCSIS 3.0 modem's Ethernet cable into the WAN port of the Airport Express....then plug in the 'smart' TV's Ethernet cable into the LAN port and it should work (i.e. I can get Netflicks directly to the HD TV).
    The Airport Express LAN ports acts as a uh, a 'bridge.'
    Whew...it sure takes a lot of thinking to do something you've never done before -- and it's all 'invisible services.'  with technology racing ahead every moment and language and definitions changing from one web site to the next.
    IMO.
