Networking :: Ethernet Plugged In But Not Working - No Hardware Detected
Oct 21, 2015
I am having trouble getting my internet connection to work with an ethernet cord. I have no problem using wifi, but I get disconnected on wifi pretty frequently. I have two ethernet cords in my possession, one of them is new, and neither works. I've tried connecting to the router and the modem.
I've used used troubleshooter with both wires while plugged into the router and the modem. I've created a connection that has our given username and our password in it.
I turn off the wifi specifically by clicking on the wifi icon on the bottom right of my computer screen. It seems that the ethernet cord is not detected.

I am completely wiping my hardrive with DBAN and doing a clean install of windows 10 with a dvd I created with the media creation tool. Will the fresh installation of windows come with a driver for ethernet cable so I can get on the internet.
I know I can get the drivers and put them on a usb to use after install, but I'm having trouble with malware on other computer and I don't want to transfer anything.It is windows 10 home on a 64 bit Toshiba Satellite C55-C5241 if that matters.

I've been running Windows 10 on my PC for a few months now. I upgraded from Windows 7 and absolutely love it! However, I am having an issue. When I use my PC on a normal basis, Everything is good. Internet connection is perfectly stable, no problems. But ALWAYS if I restart my pc, and SOMETIMES when I put it to sleep, when my computer turns back on, my internet connection can't be detected. I have to unplug it for about 5-10 seconds and do a full reboot in order for my internet connection to be detected by my pc. None of my other devices have this issue. I have an xbox one, Smart tv, my phone, laptops, etc. connected and none of them have the same issue.

I am having this issue with a Surface Pro 3 on a dock, that when it is plugged in to a certain port it doesn't recognize the internet connection. If I take the surface to a different port and plug it in it works, if I get a different surface and plug it in to the port I am working with it works. Its only when the surface I am working with is plugged into that specific port, that it doesn't work. I need this surface plugged into this port, I can't plug it in anywhere else.
I have tried updating drivers, changing the dock, and also plugging in a USB to Ethernet adapter to bypass the dock. Nothing has worked. I also can't just get a different Surface because I don't have another surface with Win 10 on it. I need to have this Surface connected to this port but it will not work.

My audio jack is not working. I have tried reinstalling the driver and nothing. My laptop's speakers stop working when I connect my headphones, but no sound comes out. They are not detected in the Playback Devices and the Sound Mixer does not pick them up. The Realtek audio manager can, although not by default, detect when my headphones connect, but again, no sound comes out. I have tried several jacks and none works.

I decided to take the plunge and install win 10 on one of my machines. Used windows update to install build 10074 from windows 7.
Everything seems to have worked fine except my network adapter (onboard Realtek thing) isn't being detected.
Figured this might be a driver thing so I installed various versions of the realtek drivers both win 7 and win 8 ones and these seem to install fine but then cannot detect the card. The installer gives an error that the card may be in "Deep Sleep mode".
Once installed the Device "REaltek PCIe GBE Family Controller" appears in device manager with no issues or conflicts, but nothing is in the Network Connections window when I go through Network and Sharing centre.
I have tried booting to the trouble shooting menu and selecting load unsigned drivers but this has not worked.
I rolled back to Win 7 and the card came back and all connectivity was restored. Re-installed win10 and back to the same issue.

i recently updated to windows 10. I'm having some difficulties regarding internet through Ethernet on It. what usually happens is i am able to surf the Ethernet for around 10 minutes, then the ethernet adapter just quits on me. So i run the network trouble shooter and find you that it needs to reset the DNS, which it does successfully. After that my Ethernet doesn't work anymore till I restart the Laptop. my computer's wifi card is an intel wireless n 7260, and the other network adapter is a pcie gbe family controller.

So i recently updated to windows 10, and i noticed i wasn't connected to my Ethernet anymore, so i had to connect my PC to the wifi. Under my "network Adapters" it only shows "Qualcomm Atheros 802.11 1/b/g/n" I tried connecting another ethernet cable, but nothing happened.

I cannot seem to connect on Ethernet though Wi-Fi works OK. I have seen several articles about ethernet problems with Win10.
CABLING
First the network config:
Two notebooks, C and D are plugged into a switch and the switch plugged into the router. Now, the cabling is verified to work because computer C, running Win7 connects just fine and if the internet cables are swapped, computer C still connects just fine.
Computer D however does not connect. I did some other things to redundantly check too, just FYI.
So cabling looks OK.
ROUTER
both computers have fixed (reserved) IP addresses in the router.
The router sees computer C
but not computer D
Just FYI, if I turn on Wi-Fi, the router sees D on WiFi, but not the ethernet.
PING
Computer C can ping D
Computer D can ping C
Computer C can ping the router
Computer D cannot ping the router
Some investigation suggested the following, all of which I tried with no better results:
- Update the network adapter drivers (already current)
- Winsock posible culprit, so NETSH WINSOCK RESET and reboot - no change
IE used to find and fix these things pretty well, but here we have EDGE. Perhaps I'll try to install IE. Connectivity diagnostics are where IE shined over Chrome and Mozilla.
UPDATE: IE 9, 10, etc. are not compatible with Windows 10. So, the connectivity diagnostics just not as good in Win10. I can tell I am getting tired, as it's getting hard not to swear.
UPDATE: Added a pretty picture.

I was wondering if it's possible to utilize both WiFi and ethernet in tandem. I'm pretty sure some of you are going to tell me that I can only access the internet through one of these, up to my bandwidth limit, but that's not what I mean.
I'd like to access the internet through my WiFi connection, yet have a wired connection through my router to access the files on the other computers in my house.

I am running Windows 10 demo version. I have problems connecting to the net. I am shown the error along the lines of "Ethernet does not have a valid IP configuration".
From command prompt I run "ipconfig/all" and here is the console's output:
When I run "ipconfig/renew" it fell through : I should add, I have no problems on Windows Vista however.

I ran Windows 8.1 on my desktop machine a few months ago, and later upgraded to Windows 10. Everything worked great at that time, but since have replaced Windows with Linux. Now I'm trying to install Windows again, with the same 8.1 disk that I used for my earlier installation, and my ethernet connection isn't found. (this is a direct wired ethernet, not wireless) I've installed with a local user account, dug into every networking utility in Windows, but whatever I do the internet goes undetected. I've run the ethernet thru different routers, and even circumvented the router all-together, but no luck. Has my 8.1 disk "expired"?

I've been having problems with my network drives which seems to have happened after a recent Windows 10 'update'
In device manager I stupidly deleted a number of Windows adaptors under the Gigabit network connection.
Now I just have the Red Cross over the Internet icon.
Ive tried reinstalling Intel drivers but they stop at 'installing network drivers for Intel 82579v Gigabit network connection'
I then get a message 'cannot install drivers - No Intel (R) adaptors are present in this computer'
motherboard is is a Gigabyte X79 UD3 running F20 Bios. The network adaptor is onboard.
I can't seem to figure out why the computer can't detect the adaptor.
There is no ethernet controller in the device manager? And the network and internet page in settings does not give an Ethernet connection option?

i've been with this problem for months and i have tried multiple solutions offered by others on the internet, yet i'll give it another try here.
i'm using a powerline adapter directly plugged into the wall on my desktop. And it has worked excellent before, but suddenly someday it did not get a valid IP adress anymore for my pc, i have tried giving it an ip adress manually but without succes. i also tried updating the driver but there was no update.
my network and sharing center displays unidentified network and windows problem solver detects the problem 'network name' does not have a valid ip configuration.

There is 2 computers and 2 virgin superhubs in the house i live in (not both mine) both ethernet connected. Occasionally i have to unplug my superhub and connect my desktop computer to the Wifi on the other hub which is in the next room.My computer obviously "remembers" the password for the wifi and i used to be able to just unplug my hub and it would automatically connect to the wifi without me having to do anything.
Since switching to Windows 10, when i unplug my hub, it says that it is connected to the wifi however it says "limited" and no websites work, effectively not connected even though it says it is.To solve it i have to leave my hub unplugged and restart my computer and it connects instantly and works. Whilst that isn't a huge problem, i sometimes could do without having to save what i'm doing just to restart the computer as i have never had to do this before.
The same problem also occurs in reserve if you get me. Disconnecting the Wifi and then plugging in the hub, it also says limited connection until i restart the comp. Virgin Media have been of no support whatsoever, to be honest I didn't expect them to be as it seems like a computer/windows problem.

So... I just updated from win 7 to win 10, as I got it for free. All went smoothly, but there was no ethernet connection. I'm running a custom built pc, connected to my router via ethernet cable.
At first windows detected the cable, but said: ''Ethernet doesn't have a valid IP configuration." I was on about around the settings, and deleted the ethernet network from windows' settings. I thought it would come back by just re-plugging the cable. This didn't happen. What happened was, that the whole 'Ethernet' tab disappeared from the 'Network & internet' menu!
I also don't have 'Wi-fi' or 'Airplane mode' tabs in the menu... Well I have a pc that doesn't have support for wifi so that might be why...
how to get win 10 to detect the ethernet cable, and maybe that way bring back the 'ethernet' tab?
Oh, and I tested the ethernet cable on my laptop (running win 7), and it worked fine.

Strange issue that just started today. My Ethernet adapter shows unidentified network and none of my apps have internet access, however my web browsers work just fine. I am even making this post from the adapter that supposedly has no access. I have been searching around for a solution, but no problem seems similar to mine. Check out the screenshot below.

My laptop is for some unknown reason not connecting to the internet via wifi or ethernet. It will also not diagnose the problem as it says The Diagnostics Policy Service is not running and it cannot fix it.

I have two computers working on Windows 7 that are directly connected to each other via an Ethernet cable utilising Windows Sharing and all works fine.
However, I have two other computers on Windows 10 that are also directly connected to each other vian an Ethernet cable and I cannot get them to see each other.
All the settings are the same as the Windows 7 devices but there may be something different in Windows 10 that makes what was a very simple process now more difficult.
How to successfully get two windows 10 devices connected and found if there is some subtle setting that I am missing.

This didn't happen right away. They worked fine for a month or so. It is not the ISP, my ISP is very reliable, they consistently give me the bandwidth I am supposed to get. 20MB down 2MB up. The problem laptop averages 0.3MB down and 1.5MB up.
The other hosts on my home network are not having any problems. I have another Win 10 Machine that was upgraded from Win 7 that is working just fine. One Ubuntu client and one more Win 7 client.
Fixes I attempted:
I went to the HP website and applied the recommended updates.
Checked Microsoft updates - none were suggested or required.
I removed and readded the network adapter drivers. Several times.
The hardware in question is:
HP Envy 17t Laptop
OS: Windows 10 Pro Version 1511 (OS Build 10586.36)
Wireless:Broadcom BCM43142 802.11 bgn Wi-Fi Adapter driver: 6.223.215.14
Ethernet:Realtek PCIe GBE Family Controller Adapter driver: 10.1.505.2015

I have a problem with my internet connection. First, I've tried a PCI Wi-Fi card and a repeater and nothing change.
My computer have a problem with the internet connection. When I play games like Counter-Strike, I'm spiking and I have some rollback every 5s. Here's a picture of my internet connection in the task manager:
As you can see, I'm spiking alot. Sometimes, my PC disconnect from the router (even when it's wired).
What I tried:
- Recovery
- Flush DNS
- Renew IP
- Uninstall/Install network drivers and adapter
- Uninstall/Install general drivers
And... nothing worked, except one thing: Fix network connection issues - Windows Support
Type netsh winsock reset and press Enter.
Type netsh int ip reset and press Enter.
Type ipconfig /release and press Enter.
Type ipconfig /renew and press Enter.
Type ipconfig /flushdns and press Enter.
It's working for like 30 minutes and then I'm spiking and lagging again. I suppose it's a DNS/IP problem. I need to do it again every time I want to play 30 minutes.
PS: When I'm browsing on chrome, I don't see the spike effects, only when I play or skype.

I have a kind of big problem with 10 Pro. My problem was "ok" in 8/8.1 Pro. As title says, I would like to give WiFi priority over ethernet. Why ? You may ask, I'm using laptop as a hyper-v machine ( prepare migrations from 2003/2008 to 2012 and others IT Admin things ). I know where to change priority but Settings aren't saved. Even after setting WiFi on top of ladder, after going to the settings again it's 3'rd. That way I have no internet connection because of my VM Networks and their DNS settings.

Where to start so to begin with my issues started when we got a new router. We had issues with the old one so we installed a new router and got it working fine WiFi worked alright but Ethernet would not connect it my computer when I ran the troubleshooter said one or more network Protocols were missing from my computer I'm running windows 10 version 1511. I went on google on my laptop to start finding a fix and I must have tried every option in the book just about I am losing my mind over how to fix this. Finally I tried reinstalling the Network drive Uninstalling my current one going on google finding my most updated one ect. and now the issue is no longer about the protocols but its saying my Ethernet doesn't have a valid IP configuration
