hmm the #3 part doesnt sound too weird, sometimes lve had things do that before however the hand sounds like sharing so my suggestion would be to visit the network connections, right click then go properties and then the advanced tab and de-select anything that has to do with sharping.. might be a lil different with wireless but the option should be off the properties menu, just never had to visit those kinda settings before as l have never needed things like that turned on.
