Windows 10: Ethernet adapter is not recognized

Hi, I have a ky-688 lan-usb adapter with usb hub, the hub is working with no problems, but since yesterday the adapter is not recognized or sounds constantly plug in and plug out notification.I tried with other lan cable and a pc with lan port, but the problem is only with the adapter.In the device managers the adapter was hidden and appears "Currently, this hardware device is not connected to the computer. Code 45". Then I uninstalled the adapter and now when I plug in it doesnt even appear as hidden, but the hub is still working.I would very much appreciate the help, thank you in advance.

IP configuration not valid - interference from ethernet adapter?

Solution 1: No Internet Access In Windows 8.1or Windows 10

Step 1:

Go to Device Manager → Network adapters.
Step 2:

Expand it (Network adapters).


Step 3:

Select your network adapter


Step 4:

Right click on your wireless network adapter or Ethernet adapter and then tap “Update Driver Software”.
(in this case your network adopter is Ethernet adopter so tap your Ethernet adapter)
Step 5:

Now on a new window you will need to click on “Browse my computer for driver software”.




Step 6:

Then select “Let me pick from a list of device drivers on my computer”.



Step 7:

Now choose the “Manufacturer’s drivers” from the list of two and then click next.



Step 8:

After the completion of the process just restart your PC and check if the problem is solved or not. If not, goto solution 2.



Solution 2: No Internet Access In Windows 8.1,windows10

Step 1:

Open command prompt.
Step 2:

Just go on hitting the enter after typing the each command.
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disable
netsh int tcp set global rss=enabled
Step 3:

Now to check if the settings are disabled type:
netsh int tcp show global
then hit enter.
Step 4:

Now the thing left is just rebooting your system and just check if the problem is solved or not and just give feedback.*chuckle*Thumbs

 

Computer not recognizing Ethernet cable

Hi Vijay, I appreciate your help.

I will try each step even if I've already done it, just to make sure, and post my results.

A. When I troubleshoot internet connections, it tells me “Plug an ethernet cable into this computer” and says my cable might be broken or disconnected. However of course i have tried a different working cable with no luck.

when I troubleshoot network adapter, it says “plug an Ethernet cable into the network adapter ‘Ethernet’” which of course has already been done so it is not recognizing it.

B. I tried every suggestion/step listed (except for the wifi troubleshooting since my computer doesn't have wifi) and none of them worked.

C. When I run the windows update troubleshooter, it tells me “download and install pending updates” (Maybe it is not up to date because I tried reinstalling windows 10 to see if that would fix the internet, but it did not. I updated it like last week or
something like that) but of course I can't download the updates without internet. If I click “apply this fix” it tells me to plug in an Ethernet cable. But i believe windows 10 was up to date before this issue even began because I updated it just a week ago.

D. I do not understand this step. The guide is confusing to me. It also appears that I have to download tools in order to do this repair. I cannot download anything because my computer cannot connect to the internet. I don't have a USB flashdrive. I did
try reinstalling Windows 10 though and it did not help.

 

Ethernet Adapter Won't Recognize Ethernet Cable

We have a Dell all in one touch screen computer and we want to connect our modem to it. However I noticed that the connection icon on the right bottom hand side doesn't indicate that there is a wired connection.

So I went to the network adapters page and it says "network cable unplugged" even though the ethernet cable is in there. I thought the ethernet cable might be the problem even though it was working fine for the other computer. So we switched it out and the
computer still won't recognize that an ethernet cord has been plugged in.

Then I used my mobile hotspot to install the latest driver for the ethernet port and it installed. The driver date went from 4/2/2015 to 5/2/2015. I restarted the computer and tried both ethernet cords again and same result. So then to be sure it was the
computer I put the ethernet linking the modem to my laptop and my laptop recognized the wired connection.

So it's not the cords or the modem, it's the computer. But I can't figure out how to fix it and I find it hard to believe that this is a hardware problem given that this computer is fairly new.

The OS is Windows 10 and the Ethernet Adapter says Realtek PCIe GBE Family Controller.





If our computer can't recognize ethernet cords we can't use our modem...
