what kind of guests visits, that you don't trust with your wifi access??
It's not a question of trust but probably convenience. Perhaps OP filters MAC addresses...perhaps OP doesn't broadcast...perhaps OP doesn't want to spell the SSID every time (not to mention the key)...perhaps OP prefers a "tight" network...perhaps OP wants to admin the network his or her way.
in the old days i could hide the ssid, not so much any more with equipment i'm willing to add.
i broadcast my encrypted ssid & maybe see one intrusion/month.
