Step-by-Step Troubleshooting Guide
1. Verify IP Configuration
Incorrect IP configuration can often cause connectivity issues. To verify and modify IP settings, follow these steps:
- Open Command Prompt
- Type
ipconfig /alland hit Enter - Ensure that the IP address, subnet mask, and default gateway values are correct
2. Reset Network Adapter
Sometimes resetting the network adapter can resolve the issue.
- Open Network and Sharing Center
- Click on ‘Change adapter settings’
- Right-click on the network adapter and select ‘Disable’

3. Update or Rollback Network Driver
Driver issues can cause the adapter to malfunction. Updating or rolling back to a previous driver can help.
- Open Device Manager
- Expand ‘Network adapters’
- Right-click on your network adapter and select ‘Properties’
- Click on the ‘Driver’ tab and choose ‘Update Driver’ or ‘Rollback Driver’
4. Adjust Adapter Settings
Incorrect adapter settings can hinder proper network functions. Ensure the adapter settings are optimized.
- Open Network and Sharing Center
- Click on ‘Change adapter settings’
- Right-click on the network adapter and choose ‘Properties’
- Select ‘Internet Protocol Version 4 (TCP/IPv4)’ and click ‘Properties’
- Choose ‘Obtain an IP address automatically’ and ‘Obtain DNS server address automatically’
5. Use Network Troubleshooter
Windows includes a built-in Network Troubleshooter that can automatically diagnose and resolve network issues.
- Open Settings
- Click on ‘Network & Internet’
- Select ‘Status’ and click on ‘Network troubleshooter’
- Follow the on-screen instructions
Advanced Troubleshooting Steps

Resetting the TCP/IP stack can resolve deeper network issues. Here’s how:
- Open Command Prompt as an administrator
- Type
netsh int ip resetand hit Enter - Restart your computer
2. Check DHCP Settings
Dynamic Host Configuration Protocol (DHCP) assigns IP addresses. Verify if DHCP is enabled:
- Open Command Prompt
- Type
ipconfig /releaseand hit Enter - Type
ipconfig /renewand hit Enter
3. Check for Malware
Malware can compromise your network settings. Perform a complete system scan using reputable antivirus software.
- Update your antivirus software
- Perform a full system scan
- Remove any detected malware
Hardware Inspections
1. Inspect Physical Connections
Faulty cables or ports can obstruct network connectivity. Ensure all physical connections are secure.
- Check Ethernet cables for any signs of damage
- Try connecting to a different port on the router
- Use a different Ethernet cable if available
2. Test with Another Device
Testing with another device can help isolate the issue. Connect another device to the same network to see if it encounters similar issues. If the second device connects successfully, the problem lies with your original device.
Conclusion
Troubleshooting a network adapter that won’t acquire an IP address can be a systematic process if you follow these steps. From initial checks to advanced troubleshooting, this guide covers everything you need to restore network connectivity efficiently.
