Before you buy a new Wi-Fi router

A new Wi-Fi router is useful when it addresses a limitation you have identified: unsupported equipment, inadequate coverage, unreliable hardware or missing features. Start with the problem, then choose the equipment. This is a research-based buying guide, not a hands-on product review or a ranking of tested models.

1. Check whether a new router will help

• Wi-Fi is weak in distant rooms: compare the same device near the router and in the problem room. Try placement changes first using our weak Wi-Fi in one room guide.
• The connection drops: compare devices and note whether they disconnect together. Follow our Wi-Fi disconnection guide before assuming the router is faulty.
• Wi-Fi stays connected but there is no internet: check service and device symptoms with our no-internet troubleshooting guide.
• The router no longer receives security updates: check the manufacturer’s support information for the exact model. Replacement may be justified even if coverage seems adequate.

If a wired connection to the router also fails, investigate the modem, router and service. A more expensive wireless specification cannot repair a provider outage. If only one device has trouble, check that device before replacing equipment for the whole home.

2. Choose the type of equipment

These are starting points for a shortlist. Your building, equipment and cable routes determine what works.

• A single Wi-Fi router: a reasonable starting point when one well-placed unit can cover the area you use. Its location still matters.
• A mesh system: worth considering for several rooms or floors. Multiple units cooperate to provide coverage, but each needs a reliable connection to the rest of the system. Check whether the models support wired connections between units.
• A range extender: may suit a small problem area when the current router works well elsewhere. It needs a reliable upstream signal; putting it in a dead spot can disappoint. Mesh integration requires explicit compatibility.
• A wired access point: can add Wi-Fi in a distant area when you can connect it to the existing network by Ethernet. Check how it is powered and configured.
• An Ethernet cable: may be enough for one stationary computer or TV, avoiding a larger wireless upgrade.

TP-Link’s network expansion guide explains extender and mesh approaches. Treat manufacturer advice as product-specific guidance, rather than an independent comparison of every brand.

3. Confirm compatibility with your internet provider

Ask your provider these questions before ordering:

• Can I replace the supplied router, or should I keep the gateway and add my own equipment?
• Does the supplied gateway also handle telephone or television services?
• Should the new equipment use router mode or access-point mode? Is bridge mode needed, and will it affect other services?
• Are there login credentials or connection settings I will need?
• What support will the provider offer if I use my own router?

A standalone router does not automatically replace a cable or DSL modem, or fibre termination equipment. Confirm the exact connection arrangement. Avoid changing modes just because a generic setup guide recommends them.

4. Compare ports, coverage and setup

Count the devices you want to connect by cable and check the number of usable LAN ports. If you need wired performance above 1 Gbps, check the speed of both the internet-facing port and the LAN ports, along with your connected equipment.

For mesh, confirm which units have Ethernet ports and whether your intended wiring layout is supported. “Mesh” does not guarantee every point can be wired. For example, Google’s Ethernet guidance distinguishes Nest Wifi points without Ethernet ports from models that can use wired backhaul—the connection between mesh units.

Check whether setup needs a phone app, account or internet connection. Review guest-network controls, automatic update options and which features require subscriptions. Choose features you will use and understand.

Advertised wireless speeds and coverage areas are not a promise of the speed or coverage in your home. Walls, placement, connected devices and the connection between mesh units can change the result.

5. Check security updates before buying

Find the exact model and hardware version on the manufacturer’s support site. Look for a stated support period or end-of-support date, current firmware and clear update instructions. If the support period is unclear, ask the manufacturer rather than assuming a new retail purchase means years of updates.

Check end-of-life notices for discounted older models. ASUS’s end-of-life list is one example of the model-specific information to look for; other brands have their own policies. This link is a support reference, not an endorsement of a particular product.

6. Buying in Canada or the United States

• Regional model: verify the exact model is intended for your country, and check local warranty and technical support. Similar names can conceal different hardware versions.
• Seller: confirm who sells and fulfils the order, especially on a marketplace. Check whether the manufacturer recognizes the seller for warranty purposes.
• Total price: confirm CAD or USD, taxes, delivery charges and any cross-border costs before comparing offers.
• Returns: check the return window, opened-product conditions, restocking fees and return shipping costs. Do not assume you can freely return installed equipment.
• Ongoing costs: include optional security, parental-control or management subscriptions in your comparison.

Use the seller’s current terms and the manufacturer’s regional information. This guide does not promise a particular retailer’s price, availability or return rights.

7. Test the upgrade in your own home

Keep notes from the old setup. After installation, repeat the same calls, browsing or streaming in the rooms that matter, using the same devices. Test at the times you normally notice trouble, not just beside the new router.

Keep the old equipment and record its settings until you know the new setup works, especially when the provider supplies it. If the new equipment does not solve the identified problem, use your results to reconsider placement or configuration and act within the seller’s return deadline.
