The RTL8188FTV is an older 802.11n chipset. While it supports WPA2 security, it does not support the newer encryption standard. Driver Realtek Rtl8188ftv Wireless Lan 802.11n Usb 2.0

With the industry moving to Wi-Fi 6 (802.11ax) and USB 3.0, the RTL8188FTV is considered legacy hardware. However, its low cost and broad compatibility mean it will remain in use for years in embedded systems, educational projects (like Raspberry Pi clusters), and legacy PCs. | | Interference | Highly susceptible to Bluetooth,
