Most likely your power supply is not powerful enough. Wireless dongles may draw enough current to cause this kind of problems. Use a USB charger that can provide at least 2 Amps. A thicker and shorter cable could also help because this would decrease the voltage drop of the cable.

  • The power supply is my first guess as well. You can try connecting the wifi dongle to a separately powered USB hub. Which Pi do you have? - some of the Pi:s may have trouble supplying enough current through the USB ports, even when the power supply is powerful enough.
