ثانيا. Causes of the Error:
Several factors can cause the \”إيثرنت 2 doesn’t have a valid IP configuration\” error. The most common causes include:
1. DHCP Server Issues: If the DHCP server is not functioning correctly or is unreachable, the network adapter cannot obtain a valid IP configuration.
2. Incorrect or Outdated Network Drivers: Outdated or incompatible network drivers may prevent the network adapter from acquiring a valid IP configuration.
3. TCP/IP Configuration Conflicts: Incorrect or conflicting TCP/IP settings can lead to a failure in obtaining a valid IP configuration.
ثالثا. Troubleshooting Steps:
To resolve the \”إيثرنت 2 doesn’t have a valid IP configuration\” error, follow these troubleshooting steps:
1. Restart Your Computer: Sometimes, a simple computer restart can resolve temporary networking issues. Restart your computer and check if the error persists.

3. Reset TCP/IP Stack: Open Command Prompt as an administrator, then type the following commands sequentially and press Enter after each one: \”netsh winsock reset\” and \”netsh int ip reset.\” Reboot your computer and see if the error is fixed.
4. Update Network Drivers: Visit the manufacturer’s website for your computer or network adapter and download the latest network drivers. Install the updated drivers and restart your computer to check if the error persists.
5. Disable and Enable Network Adapter: Open Device Manager, expand the \”Network Adapters\” section, right-click on the Ethernet adapter, and select \”Disable.\” After a few seconds, right-click again and select \”Enable.\” This action will refresh the network adapter and may resolve the IP configuration issue.
6. Check Firewall and Antivirus Settings: Sometimes, certain firewall or antivirus settings can interfere with the network connection. Temporarily disable any active firewall or antivirus program and check if the error is resolved.
