Sometimes living in a big house makes getting wireless signal to all corners of the placea real pain, or you've got a room where you want a computer but no way to run the internet without drilling holes or buying a wireless card. Networking is getting quite a bit simpler thanks to Atheros' Hybrid Networking System.
The router gives you standard fare: 802.11 Wifi, Ethernet, all the usual goodies. The Homeplug AV powerline networking is where it gets interesting. Simply by plugging in the AC adapter, you've instantly got extended wireless signal and even an Ethernet port for network access on a non-wireless capable machine. No word on cost yet for this fun little device, but it is expected to ship by the end of the year.
