Yes, these devices tend to run hot and stop working. I have a urtwn(4) device that has the same problem. No fix is known. It's possible that powersaving is required for these devices to work reliably, which I don't think our urtwn(4) driver has support for. Someone with the necessary patience could try adding support for it. The Linux rtlwifi driver seems to support powersaving for this device.
