My neighbor called and asked me if I had a laptop; I said no and asked why. She said when she was logging on to hers, she was given the choice of 2 other connections besides her own. The 2 named connections were the ones that I had used, I recognized the names. I use a desk top that was set up to accomodate the possible use of another computer, but I never got one. It was originally set up with a lynxsys router, but I decided not to use it after awhile and went to just the speedstream modem. This past summer I had a borrowed work laptop at home for a little while and it's gone now. I had bought and installed a dlink router while I was using the laptop. Do I have a connection going that I don't need? Moreover, how do I protect the one I want to use from people being able to gain access to my connection? I am not at all tech savvy, so if you have some tips for me keep it as elementary as you can stand.
