Most smart TVs have an Ethernet port on the back panel that nobody uses. Mine collected dust for years. Then I upgraded my whole Wi-Fi system and router, and I grabbed an Ethernet cable and plugged in the living room TV.

Why wireless streaming isn't as reliable as you think
Wi-Fi works well enough that most people never bother questioning it. But smart TVs are in a rough spot on your wireless network. Your TV never moves. It stays bolted to the wall or parked on a console, pulling bandwidth from the exact same spot every single day while competing with every phone, tablet, and laptop your family owns. And where do most TVs end up? Living rooms and bedroomsโsurrounded by walls, furniture, and appliances that weaken the Wi-Fi signal well before it reaches the TV.
