Guest Account does not appear "Secured"

I have an E-1000 router. It works fine. Using Cisco Connect, I have set a Guest Account with a Password. When I search the "wireless networks", besides various neighbors' networks, I see my main account with a "padlock" indicating it is password protected, and my guest account ... but it does not have a padlock icon. Using Cisco Connect, I have checked and re-checked that the Guest Account has a password. In fact, at Cisco Connect it says "guests can connect using the password ....". Why no padlock icon? Is it because I am checking the "wireless networks" on a computer that is connected to the main linksys account so it "knows" I have access already to the Guest Account? Thanks.
