| Problem | Solution |
|---------|----------|
| Adapter detected but no networks found | Disable Bluetooth (2.4 GHz interference). Change router channel to 1, 6, or 11. |
| Frequent disconnects | In Device Manager → Power Management → uncheck "Allow the computer to turn off this device". |
| Linux module not loading | Run sudo dkms install rtl8188fu/1.0 then sudo modprobe 8188fu. |
| Slow speed on Windows 11 | Disable "Large Send Offload" in adapter properties. |
| Adapter gets very hot | Normal for this chip. Add a USB extension cable to move it away from other hot USB ports. |
Pro tip for Windows 11: Disable "Memory Integrity" under Core Isolation temporarily if the driver fails to load. The RTL8188FTV driver is often not WHQL-signed for modern Windows.
