Most cable internet providers offer a rented all‑in‑one gateway (a modem with built‑in Wi‑Fi). The exact model can vary by plan, location, and availability, and may include dual‑band or tri‑band Wi‑Fi and features like parental controls.

• Renting: Convenient and typically supported by the provider, but it may include a monthly equipment fee.
• Buying your own: Gives you more control over features and placement, and you can choose a standard router or a mesh system for wider coverage.
• Shopping tip: On Walmart, look for product details that mention compatibility with your cable provider and match the device to your plan speed and home size.

Availability and features differ, so checking current specs before you decide can be helpful.

Providers typically maintain an approved device list. While specifics can change, these general guidelines often apply:

• Speed tier match: For gigabit or higher plans, a DOCSIS 3.1 cable modem is commonly suggested. For modest plans, a higher‑channel DOCSIS 3.0 model may be sufficient.
• Port speed: Look for at least a 1 Gbps Ethernet port; some devices offer 2.5 Gbps for faster tiers.
• Phone service: If you use digital voice, consider a telephony‑capable modem (eMTA) compatible with your provider.
• Future‑proofing: Choosing newer standards can make upgrades easier later.

When shopping at Walmart, review the product description for provider compatibility and compare specs with your plan. Policies and compatibility can vary by area and plan.

Using your own equipment is possible for many customers. Here’s a general approach:

1. Verify compatibility: Choose a cable modem (or modem/router combo) that states compatibility with your provider and supports your plan speed.
2. Decide setup: Either a combo unit or a separate modem plus a standalone router.
3. Cable and power: Connect coax to the modem, then modem LAN to your router’s WAN. Power on the modem first, then the router.
4. Activate service: Follow your provider’s activation steps (often via an app or website) to register the modem.
5. Secure Wi‑Fi: Update firmware, set a unique network name and strong password, and enable WPA2/WPA3.

Steps can vary by device and provider, and results may differ based on home setup.

Try a simple reboot first, then a factory reset only if needed:

1. Power cycle: Unplug the router (and modem, if separate) for about 30 seconds. Plug in the modem, wait for lights to stabilize, then plug in the router.
2. Factory reset: Use the pinhole Reset button on the back. Press and hold ~10–15 seconds until lights change. This returns default settings, erasing custom Wi‑Fi names and passwords.
3. Reconfigure: Log in to the router’s setup page to rename your network and set a strong password after a factory reset.

Exact steps can differ by model. If you rent equipment, your provider’s app or support resources may offer remote reboot options. Results can vary by device.

Both setups can work well; it depends on your needs:

• Combo (gateway): One box, fewer cables, and a streamlined setup. It’s convenient for smaller spaces and straightforward networking.
• Separate modem + router: More flexibility to upgrade pieces over time and access advanced router features. It can be useful for large homes or mesh Wi‑Fi.
• Coverage and speed: Match the device’s DOCSIS standard and Wi‑Fi generation to your plan and home size. Mesh systems or range extenders can help with dead zones.

You can find both options at Walmart. Compare specs, compatibility notes, and your household’s device count before choosing. Home layouts and interference can affect performance.
