Minimize Wi–Fi interference

THERE ARE MANY potential sources of wireless interference, particularly in the 2.4GHz frequency band. Telltale signs include spots within the router’s main range where the signal is patchy. Scout about for nearby wireless devices — anything from a doorbell to a baby monitor could be interfering with the signal. Either learn to avoid these areas, see if you can change channels on the device in question, or upgrade it. For example, cordless DECT phones and wireless door chimes operate at a lower frequency to avoid interfering with Wi-Fi.

USB 3 devices may interfere with Wi–Fi signal: use shielded USB cables or plug in the devices well away from the computer’s Wi–Fi antenna.
