For example, if your WiFi broadcasts over channel 6, you could experience interference from signals in channels 4 to 8 - though interference will be greater if both signals share the same channel.
The fastest fix for channel interference is to set your router to choose its broadcast channel automatically. The way you do this varies from router to router - but usually you will need to access your router's admin panel via a web browser and find the WLAN or WiFi settings section. Check your broadband provider's help documentation for complete instructions.
