I recently upgraded from DIR-655 to DIR-825, which connects about 20 wired/wireless devices, including 2 DAP-1522, media extenders, laptops, game consoles, WHS system, etc. I've seen significant transfer speed increase in "n" devices at up to 140mbps which finally lets me stream HD tv programs without (less) stuttering. Obviously, I'm very, very happy with the router.
Question I have is, would it make sense for me to connect the DIR-655 wired to DIR-825 and use it as a wireless access point, directing all wireless g device traffic, which is about 2/3 of the devices, to DIR-655 only and all n device traffic to DIR-825? If yes, would this setup improve transfer rate between n devices and DIR-825? Or, am I better off just directing all wireless traffic to DIR-825? I would be using the DIR-655 anyway, since I could use the extra LAN ports, so I want to set up best way possible.
