The SBV2402 is only a cable modem and does not include wireless or firewall features. You can either add a wireless router or use a cable modem and router combo unit instead. I recommend the mAX Router to add Mesh system for your home network.
So, if you have this modem I imagine that your internet service provider (ISP) is Comcast/Xfinity so if you want all in one (modem, router and voice) I highly suggest the SVG2482AC. This modem supports up to 856 Mbps.
Make sure to purchase a device that is compatible with your ISP.
