Hi,
i have heard this somewhere before, is your router far away from the player?, if so it likely that its not maintaining the connection if your doing this wirelessly, blu ray players are not very strong on the signal front if the two are too far apart,
the best way if you want to update the player would be to hard wire it with a ethernet cable, or even for use in general as this is less likely to drop the connection.
by the way, did you set up your player at the beginning to connect wirelessly to your router?, you will find this in Set up- network settings- internet settings then wired or wireless set up.
