I'm currently renting a combo wifi router/modem from Time Warner and I want to buy my own to save rental charges & have better connections. There are 5 of us in household. My son has a PS4 & does some online gaming, we watch Netflix on tv & iPad. There are 3 smart phones that use wifi and a computer. The PS4 & tv I will probably plug in. Everything else using wifi. I would like to get about 10 years or so out of modem & router. We have had issues with connecting to our current system at times. Someone at Best Buy said I should buy the Netgear AC3200. I've also read that the Netgear AC1900 is a great router. What do you recommend?
