The Spectrum handoff
Spectrum's modem remains the cable handoff. If Spectrum supplied a combo unit, put it in bridge mode or disable its Wi-Fi so the new router is the only network controller.
Match the plan first
1 Gbps and below: prioritize coverage and software over 10GbE ports.
High-split / multi-gig Spectrum tiers: verify the modem's Ethernet handoff speed, then match the router WAN port to it.
Avoid double-NAT: one device routes; the other bridges.
Checkout checklist
- Keep Spectrum's modem as the handoff; buy a router, not a second modem.
- Confirm bridge mode on any Spectrum combo unit before installing the new router.
- Match WAN speed to the plan with headroom; count LAN ports for wired devices.
- Test far rooms first — mesh solves placement problems that wireless class cannot.
