No Internet on my DC/DHCP

In the past, there was no issue until we upgraded our internet to a dedicated service. Below is how my setup is configured.

ISP Router - Connects to - Sonicwall FW WAN PORT

Cable from Sonicwall LAN PORT - Goes to - LAN Network Switch

Cable from LAN Network Switch - Connects to - Server 2019 (DC/DHCP)

All computers in my domain get internet both on static and DHCP but the Server 2019 that serves as the DHCP server does not get connected to the internet on both static and DHCP.

 

Replace modem (but NOT router) with T-Mobile Home internet device?

Thanks all. Digesting.............. Will post results.

 

can't reach DHCP server after a bulding blackout?!

Hello.

After a blackout that shut down the modem, my Dell Inspiron 15 from 2021 just cannot connect to the internet. It connects to the modem, but it does not connect to the internet. The troubleshoot says that the DHCP server cannot be reached.

I have tried resetting the wifi card, uninstalling it, restarting the whole network adapters of windows and the commands here, nothing worked.

The laptop can can connect to the internet via a phone hotspot and the phone itself can connect to the internet via the modem's wifi. I tried to restart the DHCP client, but I get error 5, access denied, even though I added all the permissions I could via RegEdit to the DHCP, TpcIp and WinHttpAutoProxySvc.

I am pretty frustrated, it popped out of nothing and nothing seems work. I have also tried running the Dell SupportAssist's troubleshoot and network optimization, but nothing changed.

Can you help me?

Thanks.
