Problems with adding a router to a modem/router combo.

Long Story. Thanks for reading. Parent's got a modem/router. Problem was that when one computer (HP desktop) was used, SOMETIMES/MOST TIMES, the other laptops (2macbooks 1 lenovo) had sever lag and could not load pages. I connected an n600 router to the modem/router in order to create 2 wifi signals and have the computer connect to one of them and have the laptops connect to the other. This caused problems because now the HP desktop had internet connection and could go on youtube, facebook, apple.com and etc. However websites such as amazaon, ebay, or any other website would not work. I could do google searches and results would pop up, but i could not click on any of the links because it says connection timed out. So now i went back to one modem/router. So i am back where i started. So i was wondering what caused the HP desktop to do that? Does it have something to do with "back channeling" router?

Try just disabling the wireless entirely on the modem/router.
