Network Connectivity Troubleshooting
This playbook offers a methodical approach for diagnosing and solving both wired and wireless network connectivity issues. It provides step-by-step procedures to identify and fix common network problems.
Step 1: Verify Hardware
Check all physical network connections. Ensure cables are securely connected, power indicators on modems and routers are lit, and devices are powered on.
Step 2: Check Configuration
Review the network settings on your device to make sure it is configured to obtain an IP address automatically unless you are using a static IP address.
Step 3: Network Adapter Check
Examine your network adapter settings and drivers through the device manager to ensure proper functioning. Update drivers if necessary.
Step 4: Ping Test
Perform a ping test to your router, local devices, and external websites to determine if there's packet loss or a specific point of failure.
Step 5: Troubleshoot Router
Restart the router and modem if needed. Check for firmware updates and consider a factory reset if other methods fail to resolve the issue.
Step 6: OS Network Tools
Use built-in operating system network troubleshooters to diagnose and potentially resolve detected problems.
Step 7: Alternative Devices
Attempt to connect to the network with a different device. If successful, the issue may be with the initial device's hardware or software.
Step 8: Check for Interference
In case of wireless connectivity issues, check for sources of interference such as large metal objects, other wireless devices, or appliances that emit radio waves.
Step 9: Contact ISP
If the issue persists and you suspect it could be from the internet service provider's side, contact their support for further assistance.
