A friend has a guesthouse located 20 feet from the main house. I would like to install a 'powerline' device bridge in the guesthouse for wifi.
Is there a simple test that can be performed, before purchasing the Powerline device, to confirm that the endpoints will work with the powerline device?
2You can determine this by the circuit breaker, however, unless the guesthouse is on the same circuit as something on the main house PowerLine isn't going to be useable. – Ramhound – 2018-12-06T17:30:07.300
