Good idea, but I still haven't been able to access the configuration wizard, and so far I've not had any problems with anyone access my network...that I'm aware of. I did have a problem with my HTPC being hacked, but it is not part of my network, it just uses the guest connection of my router. I now keep the WiFi adapter disconnected, unless I have to get online for a short period.
I had thought of it as a one-way street...outbound only, but obviously the adapter doesn't have proper safeguards, or I simply don't know how to use them.
