This error indicates that Windows cannot communicate properly with the USB hardware.
Given its 1T1R design, the theoretical maximum data rate for this adapter is when connected to an 802.11n router. The chip supports 20MHz and 40MHz bandwidth channels and includes standard 802.11n features like short guard interval (400ns) and spatial spreading. In real-world scenarios, users can expect practical throughput significantly lower than the theoretical maximum, likely in the range of 70-90 Mbps under optimal conditions.

If your internet drops off every few minutes, Windows Power Management might be shutting down the adapter to conserve electricity. :
: The driver and hardware can support Antenna Diversity , which helps maintain a stable connection by switching between multiple internal antennas to find the best signal quality in environments with interference.
| Problem | Solution | |---------|----------| | | Try a different USB port (avoid USB 3.0 if possible). Check if LED on dongle lights up. | | Driver installs but no Wi-Fi | Disable Windows Fast Startup (Power Options → Choose what power buttons do → Turn off fast startup). | | Code 10 / Code 43 error | Uninstall the device in Device Manager → Unplug → Reboot → Plug back in. | | Linux not working | Blacklist conflicting drivers: sudo nano /etc/modprobe.d/blacklist-rtl.conf → Add blacklist rtl8xxxu → Reboot with rtl8188fu module. | | Low speed or disconnects | Change USB Selective Suspend settings (Power Options → Advanced → USB settings → Disable). |
