Buffalo announced a pair of new powerline networking adapters under its HomePlug brand. These include the WPL-05G300 and PL-05H, which are sold as single-units, and sets of 2. The WPL-05G300 combines a 240 Mbps powerline network adapter with an 802.11 b/g/n (up to 300 Mbps) wireless router, which supports all common security standards. In addition to its common AC plug, it features two Ethernet ports, one of which can be wired to the internet connection link, and the other as a downstream gigabit Ethernet port. The internet connection (uplink) is shared between the downstream port, other nodes connected via powerline, and the wireless network.

The PL-05H, on the other hand, is a basic powerline adapter with one downstream port. Its powerline network controller supports up to 240 Mbps bandwdith. A single unit of the WPL-05G300 is priced at 8,925 JPY (US $113), a pack of two (WPL-05G300/2) goes for 16,485 JPY (US $209.6). The PL-05H, on the other hand, is priced at 5,565 JPY (US $70) a pop, a pack of two of these goes for 10,920 JPY (US $139).
