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.
