I have a wireless router and 3 computers connected, my laptop with windows xp pro, a desktop with xp home, and another laptop with xp home, I was wondering how to disable and re-enable the other computers from my laptop, note: all the computer are wireless

Hi you need to login to the router via it's IP address and do this

Use MAC Filters to deny computers within the local area network from accessing the Internet. You can either manually add a MAC address or select the MAC address from the list of clients that are currently connected to the unit.
Select "Only allow computers with MAC address listed below to access the network" if you only want selected computers to have network access and all other computers not to have network access.
Select "Only deny computers with MAC address listed below to access the network" if you want all computers to have network access except those computers in the list.
Name: The name referencing the MAC filter.
MAC Address: The MAC address of the computer in the LAN (Local Area Network) to be used in the MAC filter table.
DHCP Client: DHCP clients will have their host name and MAC address listed here. You can select the client computer you want to add to the MAC filter and click Clone. This will automatically add that computer's MAC address to the MAC Address section

I have to go off line for a while noops will drop by and check on this post.
