So you're telling me that if I run a wireless access point rather than
a wireless router then even MAC address authorization won't protect me.
What is there then? WAP (or WEP or whatever that encryption stuff is?)
I bought a wireless router and my daughter compains that she cannot see
the shared drive on the server or the printer. I want to replace it with
a wireless access point but don't want to invite "the neighbors" in.
