I have a USB jetstart modem on comp 1, which shares the connection over the network to comp 2, and sometimes comp3 using windows XP internet connection sharing. lets say i bought all the equiptment (pci wireless card antena etc.) for a wireless access point, would my jetstart connection be shared on my wireless access point for all other people?? (i do not want this to be!)
Welcome to NZ Wireless. You can set it up through the settings on the Acceess point so only those cards in the machines you have can access the internet. Easy to do.
You will notice that when you install a new NIC that another network connection appears.
You will have connections named eg.
Xtra (shared)
Local area Connection
Local area connection 2 (wifi)
On the advanced tab of the Xtra connection properties, you will be able to select only one other network connection to share to. This could be your local area connection OR wifi connection. You choose or get a proxy server.
