It is plugged into a 4-in-1 hub, which is plugged into my laptop. The keyboard and mouse are from Microsoft, and are both a couple of years old. (I got them when I had a Windows XP desktop.) The laptop is an Acer, Windows 7 Home Edition. I've checked the batteries and know that is not the problem. Everything was fine before I moved. I went from using DSL Verizon, to Comcast. Also, now, instead of sticking, I get the wrong keys coming up, not the ones I type. Also, it seems that my mouse has slowed considerably.
