This is just the cable modem, it converts the signal on the coax cable from Comcast (or whatever) to Ethernet. From there, you need a router with WiFi. **Q: My internet is Mbps 1000 i have a netgear router this provider is fiber optic can you tell me if this is the right modem for me i have 4 tv's and a ga** A: This is a Docsis protocol modem. It does not work with a fiber provider. You should look into switching from the coax connector on the ONT (the fiber modem that your provider installed is the ONT) to the Ethernet port. The Ethernet port can supply a gigabit connection to your router, but the coax connection likely can't . Please do some quick googling on this topic so you know exactly why you're asking what you're asking. It's confusing if you don't know what the terms mean. **Q: Will this modem work with internet that comes through a phone line?** A: this is a cable modem, not a dial up modem. Will not work with a phone line, nor will a phone line provide these kinds of speeds ## Frequently Bought Together - Netgear Gigabit Cable Modem (32x8) DOCSIS 3.1 | for XFINITY by Comcast, Cox.
