Present-day appliance repair shops may be expanded in the future to offer home network repair services.  Specialized equipment, training, and continuing education for home network repairs may represent a significant investment for small repair shops.

In the future, home networks may need to tested to ensure compliance with standards and protocols.  There may be new problems that cannot be detected without testing.  For wireless applications, routine tests may be for the detection of signal contamination or intentional bugging and surveillance.  Since such problems may be difficult to detect, network testing and  diagnosis (to detect where corruption has entered a system and what are the sources) may need to be repeated regularly.
