These are small devices that can be inserted to your computer’s USB port to enable WiFi connections for your device. If a USB WiFi adapter keeps disconnecting, however, it can be quite frustrating and annoying.

You have to make sure that your WiFi adapter or dongle is still functional and working properly.
