I have recently purchased a laptop and am connecting to the Internet wirelessly. Everything works fine (other than receiving a phone call and getting disconnected due to same operating frequencies). There is about to be another laptop in the household, and have been asking questions about whether or not the second wireless connection would affect the other. I have been told no by some, but told the change the channels they are on. Being new to the wireless world, I have no idea what they are referring to. Can anybody help me out? What do they mean by changing channels? Do I need a special program to do this? Is it really necessary to do? Any help would much be appreciated.
