Can I have a mixed network of 14Mbps, 85Mbps and 200Mbps HomePlug adapters?
Yes, but they are not all interoperable. This may sound like a contradiction but it isn’t. The 14Mbps and 85Mbps are interoperable, but a connection between the 85Mbps and the 14Mbps adapters will always operate at the speed of the slower device. All of the adapters, the 14Mbps HomePlug adapter, the 85Mbps MegaPlug adapter, and the 200Mbps MegaPlug AV adapter can co-exist on the same home electrical system and operate properly, but the 200Mbps MegaPlug AV cannot connect to the slower 14Mbps and 85Mbps adapters. This is because the 14 and the 85 comply with the earlier HomePlug 1.0 and 1.0 Turbo standard and use 56bit DES encryption, but the 200Mbps adapter complies with later HomePlug AV standard and it uses 128bit AES for encryption. Example: If you need to use both the 200Mbps and the 14Mbps or the 85Mbps adapters on the same network, there will need to be a pair of each. For a 200Mbps adapter that is connected to a PC to communicate on the network, there must be a 200Mbps adapter co
