I cant find any info on that model other than its an older 6328 chip and I cant find any info on it
anyway routers have 3 chips (Wifi, LAN, Modem) and the wifi repsonse time will probably just the wifi chip (when pinging the router) speed that matters - when pinging websites its a combo of both Modem and Wifi
all I know is the Netgear GT is a 6348 modem 256Mhz chip and Atheros Wifi and the Sagemcom 2504N is a 6362 dual-core 400Mhz modem chip which controls BOTH... I think, anyway, its faster than the GT and thats why wifi is faster response...
the DG834N Iam getting is a 6358 chip 300Mhz chip (so is faster than GT) - I dunno if it is also broadcom wifi or what,,,probably will be
