Mid/high-split unlocks faster uploads, plus OFDMA for steadier peak-hour speeds. **Q: Do I need a WiFi router with this modem?** A: Yes. This modem has no built-in WiFi. Pair it with any WiFi router or mesh system, such as a NETGEAR router or Orbi. Wired devices connect directly to the modem's Ethernet ports. **Q: Do I need to activate with my ISP after setup?** A: Plug in the modem, then contact your ISP with the MAC address on the bottom label to activate. Xfinity self-activates via app; Spectrum and Cox can activate by phone. **Q: What is mid/high-split?** A: Mid/high-split is a cable network upgrade that unlocks faster upload speeds. Availability varies by ISP and region. Without it, uploads are limited to standard DOCSIS 3.0. **Q: Will this work with my home phone or bundled voice plan?** A: This modem does not support telephone service. A bundled voice plan such as Xfinity Voice will not work with your existing home phone. Contact your ISP for compatible equipment. ## Frequently Bought Together - NETGEAR Nighthawk DOCSIS 3.1 Mid/high-Split Cable Modem (CM3000) – Approved for Today’s Fastest Speeds - Works with All Providers Incl.
