Network Lock symbol does not appear
I have just installed a new modem/router and have protected its wireless network with an encrypted WEP-64 password (which appears in my Keychain lists).
However when I view the drop-down list of all the surrounding networks found by both my computers, my network does not carry the little lock symbol as it did previously, and the system Profiler says I have no security.
My iPhone does show the lock symbol against my network.
Which is correct, and what must I do?
