First let me thank you for responding. I dont know what type the adapter is (can't get into that room right now) all I can tell you is it's an ac adapter. You will have to excuse my ignorance when it comes to computers. We never had computers when I went to school. I bought a LAN card that looks like it has a telephone jack in it but my husband says it isn't. He doesn't care how he connects to the internet, via wireless or not. He has tried hooking it to the blueray device and still cant connect. I've put in over $125.00 in this thing. Hope you can help, I really appreciate it. Can supply any details you need.
