I generally don't have a need to network computers together. In fact if I do network in my home it will be for only one purpose and would prefer to have the network down 99.99% of the time.
I can run the lines needed to connect these two computers but wireless would be easier to get going.
I am just wondering if wireless is secure enough.
If I do connect two computers together I would want to set it up so I have a link on the desktop's where I can connect the network and disconnect it even if it requires me to hire out custom coding.
I guess what I am saying is would want the computers connected about once a week for a few minutes and then break the connection as easy as possible but also securely.
