I don’t bother turning off SSID. Everything I’ve heard says it doesn’t make much difference. I have A WPA2 and a strong password. I’m sure there are easier targets around than me.
Re the unsecured linksys, we found out last week my son’s account was using it as the default connection. Not sure how long that had been going on. The only way I could change it was to make his XP account an admin, then revert it back to limited after I changed the default connection via the wireless card software.
Kind of remote here and thinly populated 2 to 5 acre home sites.Plus I monitor what is connected to the network plus Password and WPA2.
