Use a LAN connection

Using a LAN connection can solve the Xfinity packet loss problem because a wired connection is more reliable than a wireless connection.

Wireless connections are more prone to interference from other devices and environmental factors, which can lead to packet loss.

Traceroute: You can use the tracert command to trace the path taken by your packets to reach a remote server. This can help you identify any problems you may be having with your Internet connection. To do this, open Command Prompt and type the following command: tracert
