I currently have cable internet service and use a Arris DG860 modem and router from the service provider. I would like to purchase my own instead of paying monthly for the one they provide. I have no idea what to purchase. My home has 1 desktop that plugs in directly to the modem and then has 3 laptops that use wi-fi and 2 tablets that use wi-fi. I'm not really tech savvy when it comes to networking, but do want speed, reliability, and simplicity at a fair price. Current speeds: 30mbps download & 5mbps upload My internet service provider stated any DOCSIS 3.0 modem is compatible with their service. I'm unsure if I should get an all-in-one modem/router or separate equipment? Will I see significant performance improvements by going with separate equipment?
