Why not get what fits your need?
like others ,in their zeal to make this wireless bridge user friendly linksys has rendered this device virtually useless for a business application.
it cannot be programed before deploying it, because both the network it is to be pluged into AND the wireless network it's going to be connected to have to both be present for setup which can only be done with the insipid disk that comes with it.
what if there is no network connection except the wireless connection where it is to be deployed ? duh.
