But the system in question has only one computer. If it has a modern

several warning messages to be ignored to have disabled the firewall.

Christian.

In our discussion, we've rather wandered away from the OP's question!

I said a wireless solution wasn't a good idea in this case because wireless
connections are more temperamental than wired and because you needed a wired
a connection to configure the router. I also mentioned security issues in
passing.

Between us, we have broadened this to a discussion on multi PC LANs, rather
than just the OP's single computer.

My previous reply was addressing your assertion that a software firewall on
each PC (in a multi-PC setup) would stop a wireless hacker from doing
anything other than getting a free internet connection. I admit that by this
time I had lost sight of the OP's question, and was talking in more general
terms.

Do you understand what I'm getting at, in the general sense?
