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.
   

 

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

 

Ethernet and WiFi Adapter Disabling on Connection

Hello everyone. I'm having a problem sometimes using Ethernet or WiFi with this laptop. It's a relatively new laptop running Windows 10. I live in China, if that's any help.

At the school where I work, using Ethernet works fine everywhere that I can remember trying it on campus, except for in my office. I spent some time with the computer people at the school, and they were unable to figure out what the issue is. They can use the
Ethernet in my office just fine, but I can't. When I plug in the Ethernet cable, my Ethernet adapter gets disabled and shows as being grayed out for a few moments, then comes back as enabled but doesn't recognize that the cable is plugged in. If I unplug the
cable and plug it back in, the same thing happens again. I tried plugging directly into the school's router, and if I remember correctly, the same thing happens there, so it appears to not be an issue with the cabling that goes to my office.

Strangely enough, I'm having the same issue with WiFi, but only with one WiFi network that I know of, and at a coffee shop, not at my school. When I try to connect to this WiFi network, it prompts me for the password, then tries to connect and exhibits the
same behaviour as when I have the problem using Ethernet: the WiFi adapter gets disabled for a few moments and then comes back enabled, not connected to any WiFi network. I can connect to other WiFi networks just fine.

Any ideas on what might be causing this?
