Windows 10: Why can't my laptop connect to WiFi, but all my other devices can?

Recently I was playing a game on my laptop and suddenly I crashed because I disconnected from WiFi, so I went to go try and connect back but now there is not even an option for WiFi, only airplane mode. All my other devices are connected to the same WiFi but my laptop won't let me.

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.
   

 

Wifi Devices connecting to the wrong subnet


I just installed a Dlink DIR-890L and it is setup to assign devices to the range 192.168.1.1 to .254





However, it seems that when most of my devices connect they are ending up with an IP address that is 192.168.0.something.

This is causing the device to be able to connect to the router but not to the Internet. It has happened with my laptop, 2 cell phones and wireless thermostat. I have no idea why. Right now I am going into each device and changing the default IP and then manually changing its gateway to 192.168.1.1 (it's also coming up wrong)

I have no idea why this is happening.

I see this in the router settings but there is no where to change the default gateway but I'm not sure if I need to and so far I have been changing it to 192.168.1.1 on all the devices that I have to manually configure/





Any suggestions?
