ipconfig is a command-line tool that displays the current configuration of the network interfaces on a Windows PC. It can also be used to release and renew the IP address, flush the DNS cache, and display the routing table. If the PC is unable to ping the local gateway, the technician should use ipconfig to check the IP address, subnet mask, default gateway, and DNS servers of the PC. The technician can also use ipconfig /renew to request a new IP address from the DHCP server, or ipconfig /flushdns to clear the DNS cache.

Based on the information recorded by the technician, the network connection appears to be functioning normally. The user's computer is properly configured with an IPv4 address, subnet mask, and default gateway, which should allow the user to access the internet and online videos. The high download and upload speeds and low ping time recorded from the test laptop also indicate that the network is working well. However, the user's inability to watch online videos suggests that there might be an issue with the network card (NIC) on the user's computer. The NIC might be faulty or malfunctioning, which is preventing the computer from receiving and processing the video data. The technician should try replacing the NIC to resolve the issue.
