🧰 Basic Network Troubleshooting Steps

1. Check Physical Connections

• Ensure Ethernet cables are plugged in tightly.
• Make sure Wi-Fi is turned on (for laptops/phones).
• Check that router and modem are powered on.

2. Restart Devices

• Restart your computer, router, and modem.
• Wait 30 seconds before turning the modem/router back on.

3. Check Network Status

• On Windows:
  Settings > Network & Internet > Status
• On Android:
  Settings > Wi-Fi > Tap connected network > Details
• On macOS:
  System Settings > Network

4. Ping Test (Check Internet)

• Open Command Prompt or Terminal.
• Type: ping 8.8.8.8 (Google DNS)
• If replies come back, the connection is live.

5. Check IP Address

• Windows: ipconfig
• macOS/Linux: ifconfig or ip a
• Ensure your device has a valid IP (not starting with 169.x.x.x)

6. Flush DNS & Renew IP

• Windows:

  ipconfig /flushdns
  ipconfig /release
  ipconfig /renew
  

• macOS/Linux:

  sudo dscacheutil -flushcache (mac)
  sudo dhclient -r && sudo dhclient (Linux)
  

7. Disable/Enable Network Adapter

• In Network Settings, turn the adapter off and on again.
• Or use Device Manager (Windows) to disable/enable it.

8. Try Another Device

• Check if other devices can connect.
  If yes → problem is with your device.
  If no → problem is with the network/router.

9. Check Router Settings

• Login to your router (usually 192.168.0.1 or 192.168.1.1)
• Check for firmware updates, DHCP settings, or errors.

10. Contact ISP

• If nothing works, call your Internet Service Provider.
  They might be experiencing outages or signal issues.
