I have a secured wireless network and my Mac (Snow Leopard, 10.6.2) normally connects to it without any problems.
There is, though, an unsecured network frequently in range (called generically NETGEAR) which my machine will often, silently, connect to (despite the
Ask to Join New Networks preference being checked). This is bad because it is not just a much slower connection, but it's passing my traffic over a router outwith my control. (This will even happen when I'm within 10 feet of the router so connection strength shouldn't be too much of an issue.)
So is there a way for me to specifically ignore this network and not automatically connect to it - I presume it's because it's unsecured that it is ignoring the
Ask to Join preference?
