Hello,
- Try adding a driver for your network device.
We recommend WinPE: Mount and Customize | Microsoft Learn, especially for any driver that requires a reboot during the installation process.
You may also be able to use the Drvload Command-Line Options | Microsoft Learn to load some drivers while Windows PE is running. However, any updates made to the registry during the installation process will not persist after a reboot, even when Windows PE is running in a WinPE: Install on a Hard Drive (Flat Boot or Non-RAM) | Microsoft Learn.
- Run Wpeinit and Startnet.cmd: Using WinPE Startup Scripts | Microsoft Learn to initialize the network. By default, wpeinit runs when Windows PE starts.
- In some cases, you may need to configure firewall settings on the PC that you are trying to connect to. Windows PE supports Internet Protocol Security (IPSec): Internet Protocol Security (IPsec) | Microsoft Learn.
Best regards,
