Windows 10: How can I share a WiFi connection to another computer via direct ethernet cable?

Hello


I have a very specific problem with a temporary setup that cannot be changed right now, and I was hoping a kind soul would be able to help me.


I have a laptop and a desktop, both running latest Windows 10. The laptop can connect to a WiFi network, but the desktop cannot. I do not have access to a switch or a router.


I have been sharing the WiFi connection to the desktop via an ethernet cable, by opening upNetwork Connections, then opening Properties on the WiFi connection, and then sharing the WiFi connection under theShare tab by selecting the checkbox.


This worked fine for a few days, but I needed to do stuff on the laptop, and I shutdown and rebooted it.


Now, no matter what I do, this solution no longer works.


What am I doing wrong? Perhaps a kind person can help me?

:)

 

Wifi not connecting without Ethernet cable


Basically what happened before: After updating to Windows 10, my computer was not showing any network options. (The icon says "Not connected - No connections are available) Going into Control Panel/Network and Internet/Network Connections, it then says "Local Area Connection Network cable unplugged". I ran diagnostics and it said to plug in the ethernet cable to the network adaptor. So my wifi connection will not work with my laptop unless directly connected to by the ethernet cable. Wifi works fine with phones, ipods/ipads, and another laptop that was also updated to windows 10/a desktop still using windows 8.

 

laptop can't find wifi but connects with ethernet cable

Please try these troubleshooting steps that may help.

1. Make sure the router SSID broadcast is on.
   
2. Change the wifi channel to see if it resolves the problem.
   
3. Enter the SSID and WPA2 password manually and see if the laptop connects.
   
4. Temporarily turn off the encryption.
   
5. We go into device manager & check updates for wifi drivers, we may need to simply update the driver.
   
6. We go to Settings - Network & Internet - Status - Change Adapter Options, then right-clicked 'Ethernet' and disabled it. We do the same with wifi. Then we (with Ethernet still disabled) enabled wifi. It should re-connect to your wifi after a while.
   
7. We have to disconnect our Ethernet cable from our laptop and follow the steps:
   Start>Control Panel>Network and Sharing Center>Manage Wireless Networks and remove all wireless connections by right click on it and select Remove network from the drop down menu. After doing this, close the windows and scan for the wifi networks.
   Click on the available network and select connect. After a while, we will be asked to give a password for our wifi connection. Type the password and click on connect button. And now will be connected to our wifi network via wireless.
   
8. First is to disconnect the internet cable from the laptop then uninstall/reinstall the wifi adapter.
   Go to Device Manager and uninstall the wifi adapter.
   Once uninstalled, reboot the laptop and it should reinstall the driver automatically.
   After the reboot do try connecting to your wireless network again.
   If all these will not work, do also make sure that the wireless adapter is enabled. Depending the model of your laptop there should be key combinations on how to enable/disable it.
   

 

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.
