8 Essential Questions to Ask Before Buying a New Wi-Fi Router

Shopping for a new router but short on time to research cutting-edge networking tech? As experts who've tested dozens of routers in real-world home and office setups, we've distilled the process to these 8 key questions. They'll guide you to the ideal model that matches your needs and budget. Let's dive in.

1. Does the router support Wi-Fi 6 or a newer standard?
2. Does it support 2.4GHz, 5GHz, or 6GHz Wi-Fi?
3. Does it support QoS (Quality of Service)?
4. Does it support MU-MIMO?
5. Does it have multiple antennas?
6. Does it support mesh networking?
7. Does it have enough Ethernet and USB ports?
8. Does it support custom firmware? (Optional)

1. Does the router support Wi-Fi 6 or a newer high-speed standard?

Start by confirming the router's Wi-Fi standard. Wi-Fi 6 (802.11ax) is the current benchmark, delivering exceptional speeds and low latency. For even better performance, Wi-Fi 6E unlocks the 6GHz band, offering faster, more reliable connections than traditional 2.4GHz and 5GHz options on older standards.

5. Does the router have multiple antennas?

To maximize range and minimize latency, choose a router with multiple long-range antennas. These shine when paired with MU-MIMO and beamforming technologies, which direct signals precisely to your devices for optimal efficiency.

6. Does the router support mesh networking?

Mesh networks use multiple nodes sharing one SSID for seamless coverage and high speeds throughout your home. They're far superior to budget Wi-Fi extenders, which halve speeds and introduce lag by rebroadcasting from a single source.

While extenders save money upfront, mesh systems excel in performance—ideal for multi-story homes or larger spaces, though not essential for smaller setups.

7. Does the router have enough Ethernet and USB ports for your needs?

Wireless is great, but wired connections matter for gamers and power users. Ethernet ports deliver rock-solid low-latency links to PCs and consoles, crucial even on fast networks for streaming or competitive play.

USB ports enable network sharing of printers and drives, plus firmware updates on compatible models. Note: USB isn't for primary device connections—stick to Ethernet or Wi-Fi for speed.

8. Does the router support custom firmware? (Optional)

For tinkerers, custom firmware like DD-WRT, Tomato, or OpenWrt unlocks advanced features such as enhanced QoS or VPN support not found in stock software.

It's a game-changer for older or budget routers, boosting gaming performance on limited bandwidth. Check our DD-WRT vs. Tomato vs. OpenWrt comparison for the best fit.

Final Thoughts

Armed with these questions, you're set to buy a router that powers your network reliably. If wiring up Ethernet, our guide on selecting Ethernet cables has you covered.
