For broader compatibility with newer hardware and more advanced features, the rtl8xxxu driver is an excellent alternative that is replacing rtl8192cu in many modern kernels. You can often install it from your distribution's repositories or compile it from source.

is one of the most widely used legacy Wi-Fi chipsets in computing history, known for its compact nano form factor, affordability, and extensive compatibility with older operating systems and single-board computers like the Raspberry Pi. Introduction to the RTL8188CU Chipset

Despite being an older technology, the RTL8188CU is still widely used today in specific niches:

If you see a "USB\VID_0BDA&PID_8176" hardware ID in Device Manager, that confirms you have the RTL8188CU chip. realtek rtl8188cu wireless lan 80211n usb 20 network adapter

Getting a Realtek RTL8188CU Wi-Fi adapter to work on macOS is the most challenging of the three major platforms. This is because macOS does not include native support for this chipset.

The chip integrates an 802.11n MAC (Media Access Controller), a baseband processor, and an RF transceiver onto a single silicon die. It connects to the host computer via a USB 2.0 interface.
