HELP. Not long ago my macbook hard drive crashed and I got a new one, had it installed and then restored from Time Machine. My network hasn't change nor are the settings changed. Co-incidental timing or not, now my wifi keeps connecting first to an unsecured Netgear. I checked the advanced settings in system preferences, deleted all unsecured networks and confirmed my preferred network was on top. I unchecked remember new networks. And yet it either pops back or I have to manually select to get it to connect to the right network. I have no clue where to look since the usual advanced setting seems to be being ignored. It's driving me nuts. Does anyone know how to fix this? Is there a way to specifically block unsecured networks?
