[IMPORTANT: CHECK BEFORE PURCHASE] Required for proper function: 1) Your coaxial cables must be connected to each other via a MoCA compatible splitter. 2) NOT compatible with satellite TV direct connections (e.g. pure satellite systems without corresponding matrix). 3) You need at least 2 adapters to build a network - choose our 2 pack for the best value for money. 4) A MoCA PoE filter (sold separately) is recommended at the house entrance.
[Compatible with VODAFONE, TELEKOM & MORE] Works with most cable and fibre optic internet providers.

Works across brands with other MoCA adapters (no vendor lock-in). Supports up to 16 nodes.
[2.5 Gbps speed from MoCA specialists] goCoax focuses exclusively on MoCA technology - from home adapters to MoCA access controllers for network providers. The MA2500D delivers the full bandwidth of 2.5Gbps over a dedicated 2.5GbE network port, turning your existing coaxial cables into an ultra-fast wired network. No new wiring, no compromises.
Plug & Play - All Inclusive: No configuration required. Each pack includes coaxial cable, Ethernet cable, and power supply - all for instant start. Connect one adapter near your router and the other to your device. The MoCA network configures itself in seconds. Compatible with existing cable modems, routers and cable TV.
