Hi, the main difference between the NETGEAR PLW1000 and the PLW1000v2 is the supported powerline standard: - PLW1000: Supports HomePlug AV. - PLW1000v2: Supports HomePlug AV2, which allows for higher speeds and better performance. If all devices in your Powerline network support the AV2 standard, you will benefit from these improvements. Note, however, that the overall performance is determined by the slowest device on the network. Lg
