(I would love it if the networking-competent among us could say how freaked out those of us w/home networks should be. Is this a reason to upgrade, or switch to dd-wrt or that tomato thingy?)
the chances you're using RADIUS authentication on your home network are near zero
an easy way to tell is ask yourself: "have I installed and configured a RADIUS server on my network?"
if the answer is no, you'll be fine...
this is going to mostly affect ISPs...and *if* they utilise proper access controls, this is basically impossible to exploit in the real world...big "if" there tho...
