Windows PC can't connect to wifi with DHCP

My work laptop (only Windows device at home) was working normaly until suddenly started to give me the triangle on the wifi symbol indicating no internet connection.

I tried changing many things in the router and in Windows settings with no luck.

The only thing that made the laptop work is setting a static IP address in the Windows settings. The DHCP reservation in the router did not help.

All other computers (Apple macbooks and iMac) at home are working fine with DHCP.

This is just showing that the DHCP functionality in Orbi is still not working properly.

Any idea why this is happening other than being a software fault in the router?

    What is the IP address pool set for on the router? Try setting it from default to 192.168.1.100 to 192.168.1.200.

     

    Also do a IPCONFIG /release then IPCONFIG /flushdns then IPCONFIG /renew on the PC. Or fully reboot the PC.

    Try using the Windows Diagnostic wizard for the connection and see if this will resolve the problem.

      As I mentioned IP addresss reseravation on the router for the Windows PC did NOT help.

      Only setting up static IP address (with the same IP address I tried in the DHCP reservation) on the PC settings helped.

      Thanks,

      The IPCONFIG /release then IPCONFIG /flushdns then IPCONFIG /renew on the PC made the trick.

      It seems that this is needed everytime after changing the DHCP IP range. In fact you get a notification when you apply the changes to the DHCP IP range but the message is not really clear what it means. Now I know what it does :)
