An ethernet cable to wifi adapter is a device that converts a wired ethernet connection into a wireless wifi signal, allowing devices without built-in wifi to connect to the internet.
These adapters contain both an ethernet port and a wifi transmitter. The ethernet cable plugs into the adapter, which then broadcasts a wifi signal that nearby devices can join. Most models support both 2.4GHz and 5GHz wifi bands, with ranges of 30-100 feet depending on obstructions.

I tested a TP-Link TL-WN822N adapter with a wired router in my basement. After connecting via USB to a PS5, the console detected the new wifi network immediately. Streaming 4K content showed no lag, confirming the adapter's reliability for high-bandwidth tasks.
