Hello! I have the solution for those users who have Dual Booted your Windows 7/8/10 with Kali Linux and is needing help with Wifi!
1st: What you have to do is go boot back to Windows 7/8/10 then go open Command Prompt as Administrator or Not.
2nd: Put in ipconfig and find your IPV4 (Not your Hamachi or someone else IPV4)
3rd: Put your IPV4 on your web browser and log in using your username or password. If you didn't set one up it should be Username: admin Password: password
4th: Create a Guest Wifi and make it WPA2 and name it whatever you want.
5th: Save and log in with that wifi.

If you guys need any more help comment down below and I will try my best to reply with another method if I thought of one!
