I too get this about every hour or so, randomly, just when browsing the internet.
Not even using any P2P.
And when it happens it kills my POS router. As in it causes it to go offline and must be rebooted.
Just bought a new one today but have to wait for the cable company, TWSC, to change over the mac address for my cable modem..
But yes I really need a patch for this as well...
