Here is the situation. 1. All devices at Home are N except Tivo (G) 2. Have 2 Routers (Asus RT-N16 & Asus RT-N12) Is it possible to cascade the two routers together so the N16 is in N mode, N12 is in G mode and both have different ssid? If possible, would that still bring the speed of the entire network down to G or since its separate, N devices would communicate at that speed even though there is G devices present but on a different ssid?
