The 8-digit code found on the bottom of a SOHO router typically pertains to WPS, which facilitates a secure and easy wireless connection setup through a button or PIN method.
Step-by-step explanation:
The 8-digit code that can often be found on the bottom of a SOHO (Small Office/Home Office) router is associated with WPS (Wi-Fi Protected Setup).
This code is used to simplify the process of connecting devices to the router wirelessly, specifically designed to be used with a push-button or PIN-based setup method. WPS allows for a secure establishment of a network connection without the need for complex network security key entry.
