The teenagers each have a mobile, a laptop, and friends; almost every month the Download cap is reached; the ISP has outrageous excess charges; and no-body knows where all of the the GB went.
Share Downloads fairly between family members.
Assign a fixed static IP address to each device (mobile, laptop, tablet etc) and keep the static IPs for each person together in a group.
|☑ LAN DHCP Server Enabled|
Assign an equal share to each family member. For example: if the Download cap is 30GB/month then each family member could be assigned a quota of 30GB / 30days / 4people = 250MB/day. Round up to say 300MB/day.
|192.168.1.50-192.168.1.59||Max Total Download = 300MB/day|
|192.168.1.60-192.168.1.69||Max Total Download = 300MB/day|
|192.168.1.70-192.168.1.79||Max Total Download = 300MB/day|
|192.168.1.80-192.168.1.89||Max Total Download = 300MB/day|
