Wired Ethernet Quit Working

I am running an HP laptop with Windows 8.1. For the past year or so I have used the wired connection without issue. The other day I get home from work to realize I have no network connection. As I went through troubleshooting steps I realized that there
is no wired Ethernet adapter in the device manager. All I see is this:
When I enable "show hidden devices" This is what I see: 
There just doesn't seem to be a wired adapter even recognized by Windows, flat out vanished! The wireless works just fine, however I would really rather use the wired connection for a lot of what I do. Some of the troubleshooting steps I have done so far:
1. run sfc /scannow
2. Run chkdsk
3. Ran a Windows Repair
4. Restored Windows using the restore partition
5. Found the manufacturer ethernet drivers and installed them hoping the adapter would show up
I'm starting to think that it may be a hardware issue, I've just never seen an integrated network adapter fail without other motherboard issues.Any help or insight would be greatly appreciated.
P.S. There are no "unknown devices" in device manager

don't have bluetooth, although I wouldn't understand why that would cause a problem suddenly, although we are talking about Windows here!
Some recent updates seem to have hit Bluetooth users and made it completely disappear too.  For one of those incidents I suggested a WMIC query.  Maybe a similar query would find something for you.
Unfortunately I don't have LAN ports on my Surface but on W10TP there apparently is at least one but no Bluetooth (that I can find) and (strangely?) this works on it:
wmic.exe sysdriver where (DisplayName like "%Blue%") list brief
I'll have to try to figure out how to identify whatever it is that W10TP thinks it has.  BTW this will help me too because I am still not connected with it at all.   ; )
Oh.  sysdriver is not the right "alias".  This works too but isn't showing me the "adapter"
wmic.exe sysdriver where (DisplayName like "%Netw%") list brief
It's  nic, I think
wmic.exe nic list brief
and then I can get full details for the one I want with
C:\>wmic.exe nic where (DeviceID="0") list full /format:list
There are some Error and Status fields seen that way.

  • Ethernet quit working after installing Lion

    I had a clean install of Lion and everything seemed to be working well. All of a sudden, after three days, my ethernet connection quit working. I can continue to connect through my Airport. I tried another computer on my wired network and it worked fine so I know the network is not at fault. Connecting the ethernet cable causes me to lose my connection even with Airport on. Any ideas?

    Just got a call from the Apple Service rep. His solution worked-no idea why, but he said the problem was in some sort of "confusion" caused by the Location identification for the ethernet connection after the upgrade to Lion. Steps to fix the problem:
    - Open System Preferences-Network
    - Turn off Wi-Fi
    - Select Ethernet and delete the connection (hit the - button at the bottom left)
    - Hit the + button to establish a new connection. Select Ethernet in the dropdown next to Interface. Hit Create
    - Select the Assist me... button at bottom, and then press the Assistant... button on the popup
    - An Introduction screen appears which has a box with a Location designated for the new connection
    - Hit Continue
    - Select the appropriate modem being used to connect to the internet and hit Continue
    - Hit Continue on the next screen
    - Do not fill in any of the information on the screen that appears. Hit the Go Back button and then close out the Network Setup Assistant. Apparently, by going this far, you've established a new Location so no need to complete the setup if you've had an internet connection which was working.
    At this point you're back on the Network Preferences screen, and my Ethernet connection reflected that I was connected and had an IP address. When I opened Safari and Chrome, both opened correctly with my home page and all seemed back to normal. I'll repost if the connection does not hold.
    I hope this helps others with this problem.

  • Wired ethernet stops working on c2d MBP

    I am a new 15 inch C2D MBP owner and I'm just starting to learn all the Mac stuff... I need your help because I have a serious problem with wired ethernet stability under macOS. I need to know if it's something specific to my machine or if anyone else has similar problem.
    I am connected to a LAN with a 10/100 Mbit switch. I'm using a good cable (checked!). And my connection seems to hang from time to time. Usually this happens under heavier load (torrent plus multi-tab browsing), but it dies sometimes during casual browsing or checking for system updates. And it's anywhere from 3 minutes to 12 hours between hangs...
    The symptoms are strange. The connection seems to be on, but there's a sudden surge in bad packet received number and the network connection stops working remaining on-line. Putting the machine to sleep or manually shutting down the line helps immediately. I'm using:
    sudo ifconfig en0 down
    sudo ifconfig en0 up
    At first I suspected hardware problem but the same line works perfectly under Windows (with even higher load, and tcpip.sys patched to 1000 connections).
    It acted like this from the very first moment I got it and I have no clue if I should contact service or wait for a patch or maybe just stick to Windows (just kidding)...
    I've browsed the forum and it seems I'm not the only one with the problem:
    http://discussions.apple.com/thread.jspa?threadID=649927
    but this topic is unsolved... There's nothing really strange in system.log:

    evans_re,
    does the trackpad not work? If it works, you could try selecting “Shut Down…” from the Apple menu.
    As a last resort, you can hold down the power button for approximately ten seconds, which should force a (non-clean) shutdown.
    If your keyboard is completely non-functional (excepting the power button), then you should take it to an Apple store or other qualified service facility.

  • Help!  Ethernet quit working on installation

    I would appreciate any help with this problem. I recently upgraded from 10.2.6 to 10.4.3 and with the installation my ethernet port quit working. The Enet light on my cable mode doesn't even flash and the computer doesn't pick up the IP address from my ISP. Its like the Enet is broken, but when I run the computer in OS9 mode, it works fine. The only problem is when I run the new OS. I would appreciate any input on this problem, it has me stumped.

    you might need to do a clean install - if the port works under OS 9 it is clearly not a hardware fault. Before doing a reinstall, might also try adding a new user name and see if the problem is there too, and/or go to the network prefs and delete the ethernet then add it back again. Does the ethernet port show up correctly in the System profiler?

  • XBox 360 wired controller quit working in Lion

  • Can't browse web (outbound HTTP port 80) using wired Ethernet

    I just purchased a new 20" Core 2 Duo iMac today (Leopard installed) and I'm seeing a very strange problem: I can't browse the web using a wired Ethernet connection. Here are the specifics:
    - When I set up wireless ethernet w/ Airport, it works fine (outbound port 80 access is successful)
    - Going back to wired ethernet, when I pop down into a shell, I notice that outbound FTP (port 25), outbound SSH on port 15554 works fine. When I run curl (text-based web browser), it hangs. This tells me that its only port 80 that's giving me problems and nothing else. The network connection in general is fine.
    This tells me the following:
    - wireless ethernet is working fine
    - wired ethernet mostly works - all outbound TCP ports that I've tested work great. Its just the HTTP/Web port 80 that seems to be blocked.
    I went into the Security area and under Firewalls, it appears that the default configuration is set up to allow just about anything out and in.
    This is so bizzare - I thing as far as networking goes, the web access is the most important one, so I can't see Apple disabling this somehow. What gives??
    Earlier, I had set up a few user accounts for the rest of the family and set up Parental Controls on my two kids accounts. When I started noticing the outbound web access issues, I even went as far as deleting all the accounts to try to return the system as close as possible to how i received it.
    Anyone have any ideas why my outbound web access is blocked?
    Thanks,
    Ben

    I am not sure what the fix is but let me give it a try here for you. (Making sure edit works with questions 1,2,3)
    1. What version of ColdFusion Builder are you running. Are you sure you are running Beta 3?
    2. Can you access these files from your explorer window?
    3. Are you using RDS to connect to these files or the file system? (should be able to do both but that might be helpful to know which is failing.)
    4. Now the final question... by browse you might have a different issue. What version of CF server are you running? This might not be the issue but again could be if you are running developer version. If not an issue let me know and will try to hook up with you via connect to do an online screen share and help you out here.

  • Ethernet stopped working at last update

    Hard-wired ethernet stopped working after the last update.
    Wireless works.
    I have a trendnet wireless router. When the imac is connected via physical ethernet cable, it can actually ping and http to the trendnet and other machine on the same subnet just fine. However, it can't get beyond that. Looked at routing table and it looks fine.
    When i take the same imac, connect via wireless to the same trendnet router, everything works.
    Routing table looks identical.
    PC's in same line can be hard-wired to the trendnet router and work fine as well.
    Checked for more updates and none available.

    This is and old problem that as far as I know has not been resolved. You might try a search here to see all the other posts concerning this.
    I had a similar problem with my brand-new Mac about a month ago. It worked on my wireless system when I first booted it up and then after I updated it about 20 minutes later, it began to repeatedly drop the Internet connection. After a week of fighting it, I had to switch to Ethernet thus having only my Mac wired while my PCs cruise right along on wireless.
    When I first tried the Ethernet hookup, it still dropped a couple of times. It has not done so in the last 2 weeks, knock on wood. However, I am afraid to try wireless again as I may never get Ethernet back. Perhaps, just perhaps, Apple will resolve this in the next update if they even are aware of it.
    Sorry for no answer to your problem. I hope someone sooner or later is able to resolve this.

  • Built in ethernet not working on some networks

    Ok i have read everything there is to read, that i can find, i have asked a mac specialist, and after all of this i am still baffled. I have been connecting to the internet from the vary first day that i received my mbp, via wireless and ethernet. There have been no problems until i go to work and try to connect through the built in ethernet.
    I have received three different status messages when i try and play with the settings, one says
    The cable for built in ethernet is connected, but your computer does not have an ip address and cannot connect to the internet.
    Built in Ethernet is currently active. built in ethernet has a self assigned ip address and may not be able to connect to the internet
    built-in ethernet is currently active and has the ip address
    well with all of these messages my internet doesnt work.
    I then go home plug in my cable there and it works fine.
    Why cant life be easy...please help i am at my wits end

    I have this same problem (and error messages) using the wired ethernet at work with my MBP. I turn off to travel to work, connect sucessfully to ethernet but when the MBP sleeps I loose the IP address. I have to go into Network preferences and switch from "automatic" to another location and then back to "automatic" to get the network IP address to re-populate. This did not occur when I first got the MBP, but started a few weeks later. I used powerbook G4 on this network with no issues for over a year. Never have an issue using wireless. I think I have used wired connection in a hotel without issues. Could it be something related to this network?

  • Intel wired ethernet driver stops working

    We have this issue with several T400 and T500 series ThinkPads that the Intel ethernet driver stops working after a while. All this started to happen maybe a month ago. We have both 32- and 64-bit Windows 7 OSs.
    Wired ethernet works ok first, but after a few hours or a day or two this yellow exclamation mark appears on the network icon and it says limited or no connectivity. Wired network stops working and there is nothing we can do to fix this other than reboot the computer. It doesn't even shut down properly, just says "Shutting down" forever and blinks the HDD led maybe once a second. So we have to force it and after booting everything is ok until the next time this happens.
    When the network stops working, nothing can be done with the driver because everything just hangs. You cannot disable the connection or uninstall the adapter from Device Manager or anything. Unplugging the ethernet cable does not help either. There is nothing about this problem in the Event log other than about the symptoms of not having a network connection.
    What could be the source of this problem? Do you have any ideas about how to diagnose this problem further? We have the newest driver and I have also tried the newest driver from Intel.

    Go to Local Area Connection (Wired Intel adapter), Properties and the Configure button, in the Power Management Tab UNCHECK "Allow the Computer to turn off this device to save power".
    Window7 does NOT always resolve IP and DHCP when it come out of sleep etc. All attempt to release/renew are in vain. I have seen this on various systems for some time. Occassionally a router reboot fixes it but most of the time is the PC. Frustrating but for Wired use this should always be disabled if you're using it a lot. Power savings is not in your best interest.
    Let me know if that does it.

  • Wired Ethernet + Airport Express could not get them to work together

    I am a newbie to Mac. My daughter has a Macbook. No wireless internet access is allowed in her dorm room. Each room has an Ethernet port with a cable so she could plug it in her Macbook and access the Internet. I bought her an AirportExpress a few weeks ago. I set the Airport Express up to connect her printer so she could print wirelessly and stream iTunes to her stereo within her room. I could do both without problem, but if I turned on the Airport on Macbook, Safari could no longer access the Internet. If I turned off the Airport, then the Internet works fine. The school does not allow connecting the Airport Express to the Ethernet Lan port in her room (for security reason), so I could not configure the Airport Express as others would normally do by also plugging in the Ethernet cable.
    How could I get the above work by being able to steaming music via Airport and still be able to access the Internet via the wired Ethernet cable. Thanks

    ssbkk, Welcome to the discussion area!
    By default this is not possible. However using information from Apple's "Mac OS: Connecting to the Internet and sharing files locally at the same time" it might be possible. Try these directions:
    Choose System Preferences from the Apple menu.
    Choose the Network preference pane.
    Choose the Ethernet port since you use this to physically connect to the Internet.
    Click the TCP/IP tab. This pane should already be set up as directed by her school.
    Choose Network Port Configurations from the Show pop-up menu.
    If the Ethernet port is not at the top of the list, drag it to the top.
    Locate the AirPort you want to use for Printing.
    If AirPort is not second in the port configurations list, drag it to the second position.
    Choose AirPort from the Show pop-up menu.
    Click the TCP/IP tab.
    Choose Manually from the Configure pop-up menu.
    Enter these settings:
    Subnet mask: 255.255.255.0
    IP address: 10.0.1.201.
    Leave the router and other fields blank.
    Click Apply Now.

  • Vista: Only WIFI works, not (wired) Ethernet

    I've installed Vista Ultimate under Boot Camp where all works fine except:
    1) While my wireless network is available and connectable to the internet, Vista nowhere offers me even the possibility to connect via (wired) Ethernet. (I installed XP under VMware Fusion and I have no problem). Yes, I've checked all my connections & they're fine.
    2) Even logged on wireless, I can't see any other Mac on my local network. However I CAN see (and connect to) Vista on my iMac from any of the other Macs on the network. I think all my sharing prefs, firewall et al settings are OK by I'm stumped! Ideas????

    Is your ethernet card even listed in the hardware listings? Did you update the drivers (for Vista) by first booting into Vista, then inserting the Leopard DVD? The DVD should fire up on it's own to install those.

  • My westel modem (that I rent from my phone provider) quit working with the internet.  My airport extreme seems to be working from the dsl (phone) connection through the westel, then through the ethernet cabled to the airport extreme.  Do I need the modem?

    My westel modem (that I rent from my phone provider) quit working with the internet.  My airport extreme seems to be working from the dsl (phone) connection through the westel, then through the ethernet cabled to the airport extreme.  Do I need the modem?  Is the ethernet route less efficent that going throught the internet connection?  If I don't need the westel modem; how do I make the dsl conection to the pone port in the wall?  Thanks for help on this!

    Ok, so are you saying that your Internet is or isn't working?  Does it work if you plug your computer directly into your computer and bypass the router (make sure you power cycle the modem when you do this)?  If it is working this way, then a new modem isn't going to solve a problem with your Internet not working.  If it is going slow (try running a speedtest) then you need to call your phone company to have them take a look at why your Internet is slow.  If it runs fine this way and then slows back down when you go back through your router there is something else going on.  Try unplugging both the modem and the router, let the modem fully sign back in and connect to the Internet, after it gets signed in, plug your router in, and then after it boots up fully, try running the speedtest again...See if that helps any?  Sometimes it's just an IP conflict that happens when the dynamic IP that is assigned by your Internet Service Provider changes and the change doesn't flow smoothly.

  • Access Connection​s fails to recognize DNS server for wired Ethernet connection​s

    I'm running Windows 7 on a Thinkpad T410i.  I ran the Lenovo update yesterday which updated Access Connections from 6.01 to 6.21.  I then could not make any network connections to the Internet.  I used Windows System Restore to back out the changes made by the Lenovo updater. 
    Since then, I am able to connect to the Internet using the wireless adapter, but the wired LAN connection fails to connect to the Internet because it doesn't recognize the DNS servers  The wired LAN adapter is the Intel 82577LM Gigabit Network Connection.  The IP v4 configuration settings haven't changed (use DHCP, obtain IP and DNS addresses automatically), but it can't seem to connect to the DNS servers. 
    The message from Windows Network Diagnostics is:
    Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding. 
    The symptoms appear the same as in this problem in the Lenovo support library, but that was occuring with Access Connections 2.60, a much earlier version of the software:
    Network connection is not working if Access Connection is used to set DNS information - ThinkPad General
    Symptom
    When a wired (Ethernet or Token Ring), network profile is created with Access Connections v2.60, the user may be unable to connect to a LAN or the Internet.
    Affected configurations
    Any model ThinkPad system using Access Connections v2.60
    Does anyone have any suggestions?  Thanks!

    Just tested something and it worked.
    If I put the headphones all the way in, the mac recognizes it as a digital output.

    It's probably this crappy headphones.
