Windows 10: Why does my computer keep saying I need Ethernet cable when I have wireless wifi

My wifi keeps cutting out on my computer at random times. When I trouble shoot, it says I need to connect the Ethernet cable, I do not have one nor does my computer need it. Ive had the computer for over a year and have had no problems until recently when this started. Usually I have to leave it for a few days to fix itself. There are no other network options or atleast, it wont show me any and restarting the computer doesn't help either. It’s a HAJAAN gaming PC.

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.

 

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.
   

 

Ethernet cable not working.

You need to solve your problem one step at a time, e.g. like so:

• Connect your CAT5 cable directly to your router. If it does not work, replace the cable.
• Connect the cable to your TP-Link wall plug. If it does not work, reconfigure or replace the wall plug.
