Ethernet Cable "Not Connected" for W510

I recently reloaded my OS, and now my wired network card does not work.  The driver manager say the card is working fine.  But whenever I connect the network cable, there are no LED's light up on the card, and ipconfig says the cable is not connected.
I know it is not the cable or router, since I pulled the cable from a working T520.
Thoughts?  Did I do something wrong on the OS install, or is it hardware?
Thanks
Al

Ok. It was worth a shot.
How about trying a Linux Live CD boot? Even though Windows is reporting the card as ok, if it doesn't work in Linux, then the report is suspect and you may, in fact, have a hardware issue.

  • "Ethernet Cable Not Connected" Huh?

    I have a dual 10.3 450 G4 that I rarely connect to the internet. I kept getting the wrong date and time so I changed the battery. Now the monitor display keeps resetting to the wrong size and I keep getting the message the "Ethernet Cable not connected even though if I connect the cable to my laptop it works fine. I even tried restarting in OS 9, I repaired permissions still nothing. The system profiler tells me that the the extension is not loading. I can't find where to dump the preferences.
    Any help?
    Thanks

  • Ethernet: "Cable Not Connected" and Parallels?

    Hi, everybody!
    So, we've got a Late '06 iMac and we run Parallels to use Windows XP, since my wife's work stuff is not Mac-friendly. Our Ethernet port has not been waking from sleep properly for quite some time. The Network Pane just shows "Cable Not Connected." At first I thought it was my old router, but it's still happening with a three-month-old Time Capsule.
    I took it to my local Genius Bar, and was told that this is a "known issue" with Parallels Desktop and Leopard. I uninstalled Parallels for the weekend and deleted its network devices from the pref. pane. The ethernet port worked for a couple of days, but then it was gone again last night.
    Has anyone else run into this? Or heard about this "known issue?" I've not been able to find any information about it.
    Thanks!
    Jon

    I'm seeing the same issue with Nov 2007 iMac. Parallels has never been installed on the machine. Has any progress been made in identifying a solution?

  • Ethernet cable not connected?!

    Hello
    I have been using a wireless router for some time. Last night I decided to plug in the ethernet cable and my mac shows that the "ethernet cable is unplugged". I have tried multiple cables with my mac connected directly to the cable modem and through the router. I have restarted the modem and computer multiple times yet the mac still says the cable is unplugged. It has been about a year since I used the built in ethernet connection. I have tried this with airport on and off. Please help!

    Good news!I! I got this to work at the 1000 Base/T setting. Page loading is much faster (btw in Safari I "emptied the cache" before starting to use the Ethernet).
    Apparently, what needs to change is the Ethernet setting for both Ethernet and Airport.
    First, go to the Ethernet>Advanced>Ethernet panel. Set it to "manually" and these settings:
    Then, select OK, then "Apply".
    Next, click on Airport in the Network panel. Then Advanced>Ethernet. Set it to "manually". Then, OK and apply. When you select "apply", the Ethernet indicator ought to become active. Looks like this:
    After selecting "apply", it appears the Airport Ethernet setting reverts back to "automatically", but now has assigned an Ethernet number:
    Here, I shut-off the Airport and I'm now happily flying on Ethernet. BTW, my laptop still connects via Airport.
    The behavior here is obviously wrong, as this process ought to be much simpler. I'm going to post this thread in the L4/5 Lounge forum and see if I can get Apple's attention that way.

  • Ethernet port not connected - airport working - not able to get online

    Hi, new poster. Never had an issue with our beloved iMac 20 inch Intel Core 2 Duo 2.16 GHz - 2GB 667 MHz DDR2 SDRAM. It's old but it serves us, we hope it's not shot. Power goes out a lot here, system has surge protection but no battery backup. System just goes down without being shutdown properly. We used wired Ethernet. No the problem. Last time power just went out, the system would not boot up. I searched around and found out to use the DVD to verify/repair disk. It finally did and system now boots up. However, it says the Ethernet is not connected. It is. I tried three different cables that worked with our laptop and two different routers, all that happens is the light on the router flashed on and off. While on the network status in sys pref displays no cable detected vs. Cable connected but not connected to internet. Assumed the port was shot. OK, turned on the airport. Connects, gets DHCP assigned IP address and/or accepts static IP but when we launch Safari says it can't connect. Tried Opera browser, same thing. Sophos AV also can't connect for updates. All these network configurations had worked previously until this last power outage. Searched for help, as I don't want to waste peoples time. Found out about these things that follow: SMC RESET - PRAM RESET - Delete connection and recreate same - Network Diagnostics - Hardware Diagnostics - Verify & Repair disk ••• Nothing makes it connect to Internet. Network diagnostics gets to end but will not get connected. Hardware diagnostics regular and extended report no issues. We think the logic board is shot given everything we tried and symptoms with system. Can anyone suggest something we did not try of the things we did listed above? Please help us save this thing from the recycling center. Thanks in advance. Sorry for the long post, wanted to be thorough with what's going on and what we have already tried and done thanks to searching these forums for the last week.

    Yikes, sounds like big problems!
    Have you blown the dust out lately?

  • As a Verizon FIOS client, can we just use Ethernet cable to connect to time capsule, or do we need their router to connect to the time capsule?

    As a Verizon FIOS client, can we just use Ethernet cable to connect to time capsule or do we need the Verizon router to connect to time capsule?

    The Time Capsule is indeed a wireless router with simultaneous dual band capability...and a hard drive for backup purposes. You can use that to your advantage if you configure the Time Capsule as I suggested in Bridge Mode.
    The Time Capsule will provide a 802.11n 5 GHz band and a 802.11n/g/b compatible 2.4 GHz band to allow virtually any device to connect to the network.
    I suppose that you could also use the "g" wireless network provided by the Verizon router as a "guest" network or something similar if you really do need another wireless network.
    It might be possible to configure the Time Capsule as the main router on the network....that's a question for Verizon. But even if you might be able to do this, I'm sure it is not supported by Verizon, so you would be on your own in the event of any Internet connection difficulties on your service.
    And, since the Time Capsule does not have a built in modem....you would still need to add a separate modem to the installation anyway.
    That's why my suggestion is to use the Verizon device as the "modem" and let the Time Capsule provide the dual band wireless network and of course, handle the Time Machine backups.

  • Using an ethernet cable to connect Time Cap to iMac?

    Hello,
    This is a pretty basic question, but I'm not really sure what the correct answer is.
    I use a Time Capsule as my WiFi unit in my house (I have a cable internet connection---cable comes out of the wall and goes into a cable modem, and then from there, an ethernet cable goes from the cable modem into my Time Capsule).
    I was told by an Apple expert that I can probably get a faster internet connection if I use an ethernet cable to connect my iMac to my Time Capsule (as opposed to using it via WiFi, as I am currently doing). I have two questions regarding this:
    1) Is it true that my speed will increase?
    2) How do I connect the two together? Do I just use a spare ethernet cable and plug that into the rear of my Time Capsule, and then the other end into my iMac?
    I want to keep the WiFi part working, because I have other Apple devices that use WiFi (iPhone, iPad, AppleTV).
    Thank you for any information and/or suggestions.

    I was told by an Apple expert that I can probably get a faster internet connection if I use an ethernet cable to connect my iMac to my Time Capsule (as opposed to using it via WiFi, as I am currently doing). I have two questions regarding this:
    1) Is it true that my speed will increase?
    The expert is only providing half of the story. He forgot to tell you that your Internet connection speed is determined by the plan that you have with your Internet Service Provider (ISP).
    This is the bottleneck on your (and my) network since your wireless connection speed capability is already much higher than your ISP can ever hope to deliver.
    For example, let's say that your plan with your provider supplies 20 Mbps.  Your wireless network will typically handle much higher speeds...anywhere from 100-250+ Mbps. 
    Yes, an Ethernet connection has yet higher speed potential than a wireless connection, but if your wireless connection speed potential is already much faster than your Internet connection can deliver, having even higher speed potential with an Ethernet connection will do nothing for your performance.
    In other words, your Time Capsule (or any other router) cannot take the signal that your Internet Provider supplies and make it go faster, whether it is using wireless or Ethernet connections.
    Your Internet connection speed will only be as fast as your plan allows. If you need a faster Internet connection, you will need to speak to your ISP about a faster plan.
    2) How do I connect the two together? Do I just use a spare ethernet cable and plug that into the rear of my Time Capsule, and then the other end into my iMac?
    Yes, that is correct. Be sure to turn off the wireless on your iMac as well since you no longer need that connection.

  • Dual Ethernet will not connect if set to share Single IP address

    The subject says it all. My trusty old Dual Ethernet will not connect if set to share Single IP address.
    I cannot get anything but a self assigned IP address with it set to share a single IP address.
    Before about Tuesday of last week I had connected to it a Mac mini, iMac, Dell Desktop, Dell Laptop, and PS3 all working fine. I think Comcast or Apple updated their system or Airport software and now the old dual Ethernet will not share a single IP address.

    So far as I know, there has been no recent change in Apple's software affecting the Snow (a/k/a Dual Ethernet) base station. About 2-1/2 weeks ago, Apple distributed an update to AirPort software for Intel Macs running Tiger, but it would not have affected the base station.
    Your topic implies that when the Snow is not set to share a single IP address (i.e., presumably, when "Distribute IP addresses" is unchecked in the Network pane of AirPort Admin Utility for Graphite and Snow), one of the computers is connecting to the Internet through the base station. I also imagine that the self assigned IP address you mention is the IP address of that computer, rather than of the base station, and that that computer obtains an IP address from Comcast when the Snow is not distributing IP addresses.
    Assuming that that computer is connecting wirelessly, then whatever settings that computer is using for TCP/IP and PPPoE in the AirPort part of System Preferences, while the computer connects to the Internet, should be the ones used for the base station, in the Internet pane of AirPort Admin Utility for Graphite and Snow. (Most likely, it is simply "Using DHCP.") The IP address obtained from Comcast should be received by the base station, when it is set to distribute IP addresses in the Network pane, and the IP address should show up in the Internet pane. (When the Snow is distributing IP addresses, it has two IP addresses itself, a WAN IP address obtained from Comcast and a LAN IP address, 10.0.1.1, visible only to devices in your network.)
    Even when the settings are correct, the Snow might not be able to obtain an IP address if your cable modem remembers the computer, which had been receiving the IP address previously. You'll probably need to shut down the computers and unplug power to the base station and cable modem. After waiting 5 minutes, restore power to the modem, then after another 5 minutes, restore power to the base station, then after another 5 minutes, start up a computer.

  • What is the best ethernet cable to connect a macbook pro to a wall jack?

    Hey everyone, I have a 2012 macbook pro and next year for college I will need an ethernet cable for my dorm room. The only info my schools gives me about what cord to get is, "you will need is a standard (straight-through) Ethernet cable to connect the computer/device to wall jack." So my question to you all is, what is the best one that I can purchase? Thanks-Kevin.

    Go to Best Buy, tell them you need to connect a computer to a wall jack.  Most of the cables out there are the correct ones (literally ... 95% of the ones in the store are) and you need to ask for the corss-over cables used to connect routers to briges (do not ask ... really, do not ask).
    Do not pay top dollar for it.  I have a rag-tag fleet of cables in various stages or repair, but they mostly all work.

    You can get a thunderbolt to firewire adapter. You can then get a firewire 400 to 800 cable and put the old computer in target mode. Then you can follow these instructions.

  • Ethernet cable not plugged in? But it's right there!

    My MacBook Pro is insisting that the ethernet cable isn't plugged in. Now, I know the cable is good and the port on the switch is good because they work with my network printer. If I create a new location in Network Preferences (as suggested here http://ryanshelloworld.blogspot.com/2009/03/ethernet-cable-not-plugged-in.html) it works, but only at 10 Mbps (rather than gigabit) and when I unplug the cable and plug it back in it loses it again.
    Any ideas on what to do next?

    Try a new cable. Although it works on another device Macs are picky about the quality of the line.
