Wireless network wifi repeater and wireless network wifi adapter are two different network devices with different functions and uses.
Wireless Network WiFi Repeater
Wireless network WiFi repeater, also known as WiFi extender or WiFi booster, is a device used to enhance WiFi signal coverage. Its main function is to receive the signal from your existing WiFi router and then rebroadcast that signal to increase the coverage of your WiFi network. WiFi repeaters are usually placed at the edge of existing WiFi signals to help devices in weak signal areas get better connections. It doesn't connect directly to the Internet, but communicates with your main WiFi router to provide wider coverage.
Wireless network WiFi adapter
A wireless network WiFi adapter (WiFi adapter) is a device used to enable devices without WiFi functionality to connect to a WiFi network. These devices can be computers, laptops, desktops, printers, etc. The WiFi adapter connects to the device via a USB port or PCI slot and allows the device to connect wirelessly to an existing WiFi network. It is an external device that adds wireless connectivity to devices that do not have built-in WiFi capabilities.
The difference:
Function: The main function of the WiFi repeater is to extend the range of the existing WiFi network, while the main function of the WiFi adapter is to add wireless connection capabilities to devices that do not have WiFi capabilities.
Location: WiFi repeaters are typically placed at the edge of existing WiFi signals, while WiFi adapters connect directly to devices that require network connectivity.
Connection method: WiFi repeater connects to the main WiFi router wirelessly, and then re-broadcasts the signal wirelessly. A WiFi adapter connects to a device via wired or wireless means and allows the device to connect wirelessly to an existing WiFi network.
In some cases, it may be necessary to use both a WiFi repeater and a WiFi adapter to achieve wider network coverage and provide wireless connectivity for different types of devices.
