It depends on how your internet is delivered.

• Cable or DSL: You typically need a modem to translate the signal from your provider and a router to share it over Wi‑Fi and Ethernet.
• Provider gateway: Some providers supply a single box that combines both functions.
• Fiber: An optical terminal usually handles the modem role. You’d add a router for Wi‑Fi.
• Fixed wireless/5G home internet: The base unit often includes the modem and router.

Checking your plan type and equipment from your provider can help you choose the right setup. Product pages often note cable, DSL, or fiber compatibility.

Both options can work well; the right fit comes down to convenience versus flexibility.

• Combo unit: One device to set up, less clutter, and a single app/interface. The trade‑off is that upgrades are all‑or‑nothing and placement is tied to your wall jack.
• Separate modem + router: You can upgrade one piece at a time, place the router more centrally (via Ethernet), and choose advanced features or mesh. You’ll manage two devices and power supplies.

Whichever route you take, match the device to your internet type and speed tier, and confirm compatibility with your provider.

Start by confirming whether your plan uses DSL or fiber.

• DSL plans: Look for a DSL modem or modem‑router that supports the technologies your provider uses (commonly VDSL2 or ADSL2+) and matches your speed tier. Providers often maintain approved device lists.
• Fiber plans: The optical terminal usually acts as the modem. In most cases, you’ll only need a router with a compatible WAN port. Some setups may require specific settings provided by your internet company.

If you’re unsure, checking your plan details and approved devices can help you choose equipment that aligns with your service.

Aim for a good fit with your connection type, home size, and devices.

• Compatibility: Match cable (DOCSIS 3.0/3.1), DSL, or a router for fiber WAN.
• Speed support: Choose hardware that aligns with your plan’s speeds; newer standards can help with faster tiers.
• Wi‑Fi tech: Wi‑Fi 6 or 7 can improve capacity and efficiency for busy homes.
• Coverage: Check square‑foot estimates and the ability to expand with mesh.
• Ports & features: Look for gigabit or 2.5G Ethernet, guest Wi‑Fi, parental controls, and security updates.

Using filters and reviews on the product page can make narrowing down choices easier.

They can improve overall Wi‑Fi performance, especially in busy homes, but benefits vary by plan and devices.

• Wi‑Fi 6: Designed for crowded networks, it can boost efficiency and help multiple devices share bandwidth more smoothly.
• Wi‑Fi 7: Adds even higher potential throughput and lower latency with more advanced channel use, which can help with demanding apps.
• Compatibility: Both are backward‑compatible, so older devices still work at their own top speeds.

If you’ve got many connected devices or faster internet service, upgrading can reduce slowdowns. Actual results depend on your home layout and device support.
