There is no easy method to control bandwidth utilization on this home-based router. While you can limit access for certain applications, there is no method to limit usage of standard web traffic. I suggest you use a freeware sniffer (Microsoft Network Monitor is an easy one to download and use) to determine the type of traffic and the largest consumer. Then have a conversation with that consumer. The reason for the high utilization might be some malware installed on one of your computers – the sniffer allows you to determine this.
i think it is better to limit what kind of traffic you can use…
disable torrents and tking like that
You can configure the router to restrict the number of users. You can also set up “tunneling” for certain applications and gaming, so they get priority, or are rejected.
Hope this helps!
