- Add a DWORD
BackgroundScanPeriod with value 0 (requires reboot).

sudo dkms remove rtl8188fu/1.0 --all
sudo rm -rf /usr/src/rtl8188fu-1.0
sudo reboot

Issue 2: Constant Disconnects or "Limited Connectivity"
Cause: USB 3.0 interference or power management.
Fix:
- Move the adapter to a USB 2.0 port (or use a USB 2.0 extension cable).
- Device Manager → Network adapters → Realtek RTL8188FTV → Power Management → Uncheck "Allow the computer to turn off this device".
On Linux:

Check if it’s recognized:
