it's shure no power-saving problem, because: i'm using the boxes as router with ral. with the RT2561 Chip i had this problem only after 500MB transferred data, with the RT2560 Chip i had this problem after some MB and 3 seconds. And thats no power-saving after 3 seconds. i've no problem with a ethernet cable betweek the boxes, but only with the ral cards. i'd also no problem with prism cards. i can be a problem of the ral driver. strange ....
