Why This Matters

Router marketing is dense with jargon, and this piece cuts through it by explaining what dual-band and tri-band actually mean for everyday buyers. Tri-band adds a third network band for more bandwidth, but the article argues the upgrade isn't necessarily worth it for every household. That matters for consumers deciding whether to pay more for Wi-Fi 6E or Wi-Fi 7 hardware.

Key Takeaways

Dual-band routers use 2.4GHz and 5GHz; tri-band adds a third band for extra bandwidth.
Older tri-band models add a second 5GHz band, while Wi-Fi 6E and Wi-Fi 7 models swap it for a 6GHz band.
More bands mean better performance on paper, but tri-band isn't a worthwhile upgrade for everyone.

Worth a Look

ASUS RT-BE88U Wi-Fi 7 Router — If the article has you leaning toward tri-band, ASUS's Wi-Fi 7 lineup covers the 2.4GHz, 5GHz and 6GHz bands the piece describes, so crowded smart homes and streaming devices get room to breathe. It's a solid pick for anyone upgrading from an aging dual-band box and wanting headroom for future Wi-Fi 7 gear.

Shopping for a new router can be exciting, especially if you're expecting to finally say goodbye to network buffering at the best part of your show. But as exciting as it can be, it can also be confusing, thanks to all the technical jargon splashed across router listings, including Wi-Fi 6E, Wi-Fi 7, 6GHz and tri-band or dual-band.

On one hand, there's the good ol' dual-band router with its familiar 2.4GHz and 5GHz setup. On the other hand, there's the newer tri-band router, which is supposed to be an upgrade over dual-band routers. And in truth, it is. They have more bandwidth to work with thanks to their extra network band, but being better doesn't mean it's worth it for everybody. As you probably guessed, tri-band routers feature three network bands compared to two on dual-band routers: one 2.4GHz band and two 5GHz bands. Newer Wi-Fi 6E and Wi-Fi 7 tri-band routers take things a notch higher, dropping that second 5GHz band in favor of an entirely new 6GHz one, making it a 2.4GHz, 5GHz and 6GHz configuration instead.
