    Hello. I've searched and cannot find a direct answer to what the little check box for "b/g protection" next to the "wireless mode" drop down box in all ASUS routers' firmware does for a person. Does it mean it "protects" wireless b by making sure the router stays compatible for B devices? Or, does it mean it adds some kind of extra security to the B and G wireless transmissions? I don't have any B devices in my house and unless this setting does something else for me, I'd rather disable it.

    Thanks in advance!

    Protection mode refers to a mechanism for the G radio. Since a legacy B radio device would not decode radio signals at G rates, a protection mechanism was developed for the new G radio and the B radio to co-exist on the same network. When protection mode is enabled, every packet sent on the G rate would require initiation of the sender.

    Enabling "B/G" protection ensures that the AP waits long enough for these slower protocols.

    Suppose there are no b clients, but there are several g clients.

    I currently run without this checkbox.

    I have an ac66u, no ac clients yet, just some n and some g clients.
