According to the CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025):
"A router is a highly intelligent network connectivity device that can connect multiple network types to each other. Routers use routing tables to store network addresses and route packets based on the best path available." It further clarifies:
"Wireless routers are common in homes and offices. Functionally, wireless routers work just like their wired cousins." The default gateway in a home network is the router, as it serves as the device that connects the internal local area network (LAN) to the external Internet.
