My home wifi network is password protected, as it should be. My neighbor's is not. Because I have password protected my network, my computer continually joins my neighbors instead of mine. I have moved my network to the top of the list of the "preferred" wireless networks, but if my network is down for whatever reason my computer just re-joins the neighbor's network. I don't want to join my neighbor's network, ever. Is there a way to make it so that my computer will never join a particular network, i.e. "blacklist" it?
Remove it from the list of "Preferred Networks" and it will stop auto-connecting.
