Just purchased a Sony BDP-BX37 BLU-RAY WiFi from e-bay. It came without the wireless adapter. Can a normal adapter work or do I have to use the adapter for the unit, (about $70.00US)? I only paid about that amount for the player, so still not too bad. Its just a Usb port that will take some of the network adapter's I have(hopefuly). I don,t want to stick another adapter to the player for fear of causing a malfunction. Any help greatly appreciated.
