Windows 10 Network issue in wifi

Hi
I need to assign an ip address automatically in wifi network of my windows pc to connect different wireless . but my PC is assigning constant default gateway even a change my network setting to DHCP. it make me to delete the default gateway manually each and every time when i need to connect WiFi.
i tried many run commands like ipconfig /renew ,ipconfig /release and ipconfig /flushdhs command to delete the default gateway cache. but still i am having issue.
below i attached the screenshot of the IP configuration
