Automatic Disconnection of network

Hi All

This is my first post in this section so i hope i can get some help from you guys...Here Goes


I have a home network in the house and i was wondering ?
When i go to bed my daughter is on the internet till all hours in the morning.I would like her to go to bed earlier but she cant draw herself away from the internet.
Is there a program out there that can disconnect the network for me after say an agreed time with me and my daughter.I know i could disconnect the net before i go to bed but iam in bed so much earlier than her.
By the way the reason for this isnt that iam a mean old father.
She is got her school work to think of.

thx in advance

P.s

Iam on windows xp

 

XP-home or XP-pro?

Internet via broadband (cable, dsl) or dial-up?

ICS or ???

 

my details

Sorry please forgive me as iam new to all this

Broadband connection - Motorola sb 3100 cable modem
Windows xp pro

Hope this helps

By the way i thought about using the power managment option but i would rather get software as ive never really liked the powermanagment in windows

Thx ion advance
