A single device with a poor network connection can affect the quality of all other device connections as your router can dedicate disproportionate effort to maintaining the poor connection.
If you’re experiencing unexplained dropouts on individual devices check that all your devices have a strong network connection – if you have not-spots or areas where connection is poor, take a look at our WiFi Survey page before contacting us.
Occasionally problems can be resolved by adjusting the position of your router and devices connecting to it – please see our WiFi Coverage page for hints and tips to make your home network most efficient.
