I have 3 computers (2 desktops and 1 laptop). A router that for some strange reason jumps to the weakest network in my immediate neighborhood. There are about 6 other networks that show up on my router screen-I pick the one I set up and a few minutes later my router switches to the weakest network. It does this constantly.

Is there anyway I can erase the other networks so I don't have this very annoying problem? Thanks in advance.
