I have searched long & hard for a free utility that can monitor my home network's internet downloads. Long story short, PRTG Network Monitor (free) seems to fit my needs. Before I start installing it (7 wired desktops & 1 wireless laptop connected to a modem/router that do not support SNMP), may I ask if the freeware limitation of 10 sensors/4 probes are enough for my needs? I only want to monitor internet downloads. Thanks.
