Buying Guide

Match interface to your network

Choose adapters with gigabit Ethernet ports for modern routers and devices; consider Ethernet-over-coax (DECA) if your building has existing coax runs

Check PoE needs and power budgets

If you power cameras or access points, prefer injectors rated for the PoE standard you need (802.3af/at/bt) and a wattage that covers your device's consumption

Consider rated throughput and standards

Look for adapters specifying AV600 or later and DECA Gen3 for higher theoretical throughput, but expect real-world speeds to be lower due to wiring and noise

Account for wiring and environmental factors

Powerline and coax performance depends on building wiring, circuit separation, and electrical noise—testers or return policies help validate performance at your location

Prioritize security and manageability

Choose models that support built-in encryption or pairing and, for larger setups, management features such as VLAN tagging or pair/reset buttons for network segmentation
