- Disable or configure network protocols (TCP/IP, DNS, etc.)
- Check for conflicting network settings
- Update operating system and software to the latest versions
1、Isolate the Problem
To determine the root cause of the network issue, isolate the problem by following these steps:
- Disconnect non-essential devices from the network
- Test the network with a different device or operating system
- Analyze the network traffic to identify any anomalies
