My laptop has some checkbox "only use this network" or something similar. Without knowing your OS, the drivers employed I can't research what menus you have available. So all I can ask is you explore your options.
Also, be sure to change the RF CHANNEL on your Wifi Router to see if that helps.

I recently set up a Belkin router to network my built-in wireless notebook and my desktop. When i went to use my notebook, I found an unsecure network of my neighbors. Every five to ten minutes, my wireless connection disconnects from my secure network and attaches itself to their network. I am always interrupted by their network and I can't avoid this switch with the knowledge I have about computers and networking. What should I do?
