If the issue started after a Windows update, try in the device properties tab. Adjust Power Settings: Go to Edit Power Plan > Change advanced power settings .
Modern Windows 10 configurations utilize aggressive power-saving protocols like states. Legacy UB93 drivers (originally designed for Windows XP, 7, or early 8 builds) struggle to process these power state transitions. Instead of entering a low-power idle state when network traffic drops, the driver keeps the adapter's transceiver stuck at peak voltage, generating continuous physical heat. 2.

A: It's very likely. Start by reinstalling the driver via Device Manager. If that doesn't work, check your USB port and the adapter's power management settings.
With these steps, you should now have the UB93 driver installed and configured on your Windows 10 system. If you're still experiencing issues, feel free to leave a comment below, and we'll do our best to assist you. If the issue started after a Windows update,
If your router is close, go to the adapter’s "Advanced" properties in Device Manager and set "Preferred Band" to 5G.
This prevents Windows from temporarily cutting off power to a warm adapter, which often results in a permanent system hang until the USB is unplugged: Legacy UB93 drivers (originally designed for Windows XP,
The UB93 chipset (commonly found in Realtek-based USB Wi-Fi adapters, Bluetooth dongles, and multi-format card readers) is notorious for driver issues on Windows 10. When the driver is outdated, corrupted, or misconfigured, it can cause excessive CPU usage, high power draw, and—yes—literal heat buildup in your USB port or adapter.
Hardware running at high temperatures is a frequent root cause of data corruption and driver crashes. The UB93 device architecture frequently uses legacy wireless chipsets packed into dense, unvented USB housings or integrated motherboard slots.
