Study Notes
Diagnose Connectivity Issues
- A network connection can be diagnosed based on visual cues and functionality tests.
- A crossed-out globe icon in the notification area indicates no internet access or available connections.
- A web browser may display an error message referencing lack of internet connectivity.
Windows Network Troubleshooting Tool
- The troubleshooting utility in Network and Internet Settings can help identify and attempt to fix network connectivity issues.
- The tool may identify problems like a disabled network adapter, requiring administrator privileges to apply the repair.
Command Prompt for IP Addressing
- The ipconfig command displays the status of network adapters and their IP addressing information.
- An autoconfiguration IPv4 address starting with 169.254 indicates that Automatic Private IP Addressing (APIPA) is active, suggesting a problem with the DHCP server.
- APIPA assigns addresses locally, preventing communication with other network devices.
Fixing IP Addressing Issues
- Manually assign an IP address, subnet mask, default gateway, and DNS server address.
- Contact the network administrator responsible for the DHCP server.
Verifying Connectivity on the Local Network
- ipconfig /release command releases automatically assigned IP addresses.
- ipconfig /renew command renews the IP address by sending a DHCP Discover packet and obtaining a new IP address from the DHCP server.
- Ping the default gateway using the command ping 192.168.30.1 to check for local network connectivity.
Verifying Connectivity to the Internet
- Ping a host outside the local network, like 8.8.8.8, to confirm internet connectivity.
- Ping a hostname like www.google.com to verify DNS name resolution is working.
Summary
- This demonstration highlighted tools and practices for troubleshooting network connectivity problems.
- Key tools include Windows Network Troubleshooting, ipconfig, and ping.
- Understanding IP addressing, especially APIPA and DHCP, is crucial for network troubleshooting.
- Verifying local and remote network connectivity is essential for identifying the source of the problem.
