Frequently asked
Combos are cheaper and tidier but separate units let you upgrade WiFi every two years without replacing the modem. I usually recommend separates for tech-forward homes.
Every model I compared is on the approved list for Xfinity, Spectrum, and Cox. Always check the latest ISP approval page before buying because lists change.
