Powerline network adapters turn a building's electrical wiring into a network path: adapter pairs that carry an Ethernet connection over existing power lines to a room a cable or wireless signal cannot reasonably reach. For older buildings and awkward layouts where running new cable is impractical, powerline networking gets a device online without construction.
Powerline performance depends on the building's wiring, not just the adapter's rated speed - electrical panels, circuit breakers, and other equipment on the same lines can all affect throughput, so treat rated speeds as best-case, not guaranteed. Keep adapter pairs on the same electrical phase where possible, and avoid routing through power strips with heavy surge filtering, which can block the signal. For anything speed-sensitive, wired Ethernet or a proper wireless access point remains the more predictable choice. COLAMCO supplies powerline networking adapters for the buildings where running new cable is not the practical option.
