I need another network point downstairs, and am sure in the future I'll need more anyway, so am thinking of putting a Netgear GS105 in behind the tv, and connecting it to the long Ethernet cable I have running upstairs to my AirPort Extreme. The aim is to have gigabit Ethernet put out from the airport, down to the switch, and the items that connect to the switch receive a gigabit connection. So I assume this is fine since the GS105 is 10/100/1000. With that, one of the items I have connected downstairs is an Apple TV. I have this on a static IP of 1.3 - which I think is reserved for it by the AE using its MAC address. Will this reservation continue if I put a switch in the mix? Ie, the ATV will still get 1.3, and anything else connected to it (for example a PS3 or smart tv box, will just receive IP's dished out by DHCP from the AE?
