purchase this item to replace my `` end-of-life '' cable modem and have nothing but problem . it disconnect every couple of hour and have to be reset . this be not very convenient when work from home and be downright impossible when I be away from home and try to access my system remotely . my internet provider tell I they have have nothing but problem with this brand of modem and they find it to be incompatible with they system -- even though the manufacturer claim it be .
