Why pick Xfinity?
Why pick Xfinity over the alternatives? It depends on what's serviceable at your address and what you're optimizing for. Xfinity runs a cable network, which means strong speeds and reliability where the infrastructure exists. The pros and cons section on this page summarizes real customer feedback. Before you sign up, always run an availability check at your ZIP — even nationwide carriers don't reach every address.
Xfinity equipment & modems
Xfinity provides the modem and Wi-Fi equipment needed for service in most plans. Some plans include the equipment fee in the monthly price; others charge a $10-15/mo rental. You can typically buy your own compatible modem to avoid rental fees — check Xfinity's approved-device list. Self-installation kits are standard for non-fiber plans and ship in 3-5 business days.
Installing Xfinity
Xfinity installation depends on the plan. Cable, DSL, and fixed-wireless plans usually offer self-install kits — connect the modem yourself in 15 minutes. Fiber plans typically require a professional technician visit (2-4 hour window) for the optical network terminal install. 5G home internet is fully self-install. Same-week appointments are usually available; same-day in major metros.
Xfinity pricing & fees
Xfinity pricing follows the industry pattern: a 12-month promotional rate, then a higher regular rate. Add equipment rental ($10-15/mo) if not included, and any local franchise fees. Bundles with TV or mobile can save $20-40/mo. Watch for: hidden installation fees on professional installs, early termination penalties on contracts, and price hikes after promo period. Always confirm the final post-promo price before signing.
