One of our notebooks keeps dropping internet connections. To see if it's a wireless card issue, we turned off the wireless card and used a usb wireless adapter and still connections keep dropping. I've heard that sharing can create these issues, so I'm trying to turn off all sharing. I have one PC that keeps showing up in TIVO's NOW SHOWING list. I want to turn this pc off but don't know how. I've searched everywhere in the Network and Sharing section of Windows 7 and can't figure where to turn whatever it is that I need to turn off. Can anybody who knows there way around windows 7 help me navigate to whereever it is that i need to go to and turn off so that the TIVO can't see it? Thank you in advance!
