Is there a way to access connecting to other wifi networks in range? I have an office and there are few wifi networks in range. Some of them are not password protected and invariably I get connected to that wifi first. I have talked to the person who owns that wifi. But he is somehow not listening about adding password to his network. So, is there a way I can block that Wifi network completely so that I do not connect to it? I have Win 7 and Mac at my office.
