Strange, because different security software packages shouldn't restrict access to a LAN ... I presume you're connected wirelessly?
I think you sometimes get some kind of interference; I have a laptop connected wirelessly to a router, and the straight-line distance between them is probably no more than 20 feet, but sometimes the connection drops out for no known or good reason.
One evening last week, I moved the laptop to the same room as the router, so the straight-line distance was less than 6 feet. I still had a momentary drop-out, but it did connect again a couple of minutes later.
