WiFi Standard and Speed Class
The TP-Link BE400 is a WiFi 7 (802.11be) router, which is the headline reason to consider it over a similarly priced WiFi 6 router. It is dual-band rather than tri-band, however, so it does not include the 6 GHz radio found on the BE550 reviewed earlier in this guide. Its BE6500 class delivers up to about 6.5 Gbps of theoretical throughput across the 2.4 GHz and 5 GHz bands, with WiFi 7’s 320 MHz channels on 5 GHz contributing to higher peak speeds than earlier dual-band WiFi 6 hardware.
MLO is the more important practical feature on a dual-band WiFi 7 router because it can use both available bands at once for a single link, which helps mitigate the lack of a third radio. For households without WiFi 7 phones or laptops that specifically need the 6 GHz band, the BE400 is a sensible way to bring the network onto the new standard at a lower price than tri-band WiFi 7 hardware — see our best WiFi 7 routers guide for context.
Range, Coverage and Mesh Capability
TP-Link rates the BE400 for coverage up to roughly 3,000 sq ft, which makes it a strong fit for medium to fairly large homes when well placed. The router uses antennas tuned for stable signal across that footprint and EasyMesh support means the BE400 can be paired with other TP-Link EasyMesh devices if a single router does not cover every corner.
Rated coverage figures from manufacturers are best treated as a guide rather than a guarantee — they assume relatively open conditions, and a router that nominally covers 3,000 sq ft will reach less ground in a multi-floor brick-walled house. For very large or multi-floor homes, dedicated mesh kits remain the better choice — our best mesh WiFi systems guide is a useful reference. For buyers comparing tri-band WiFi 7 routers, the BE550 reviewed earlier adds the 6 GHz band at a higher price.
Ports, USB and Wired Backhaul
The BE400 carries dual 2.5 Gbps wired ports, which is the key practical advantage over Gigabit-only routers at this price. The 2.5 Gbps WAN port supports modern 2.5 Gbps broadband plans, while a 2.5 Gbps LAN port gives a wired path to a 2.5G-equipped gaming PC or NAS that is not bottlenecked at 1 Gbps. The router also includes a USB 3.0 port for sharing a storage drive or a printer over the network — a useful feature that the higher-priced BE550 reviewed earlier in this guide omits.
For gamers, the multi-gig wired layout is the single most useful detail. Buyers who are not yet on a multi-gig broadband plan still benefit from the 2.5 Gbps LAN side: a wired multi-gig link between two devices on the local network (for example a gaming PC and a NAS) does not depend on the broadband plan and can move large files dramatically faster than a Gigabit-only setup.
Gaming Latency, QoS and Security Features
WiFi 7’s lower tail latency through MLO and wider 320 MHz channels benefits the BE400 on compatible client devices, although a dual-band router naturally sees more contention than a tri-band one in a busy household. The TP-Link Tether app, HomeShield security feature set and full QoS controls let a gaming PC or console be prioritised over other traffic.
A wired connection through the 2.5 Gbps LAN port remains the most effective way to keep latency low and consistent. Buyers who want the wireless gaming experience to match the wired one as closely as possible should look at a tri-band WiFi 7 router instead; on a dual-band router the MLO benefits are still real but more limited because only two bands can be combined. For deeper tuning advice, see our low-latency gaming network guide.
Who Is the BE400 For?
The BE400 is for the buyer who wants WiFi 7 and multi-gig wired networking without paying for a tri-band router. If your broadband plan is at or near 2.5 Gbps, your gaming PC has a 2.5G Ethernet port, and you do not specifically need the 6 GHz band today, the BE400 is squarely your router. It is also a strong pick for the buyer who values having a USB 3.0 port for shared storage on a WiFi 7 router. It is not the right router if you specifically need 6 GHz for compatible devices — for those, see the BE550 above or our best WiFi 7 routers guide.
Pros and Cons
Pros: WiFi 7 standard at an affordable price; BE6500-class throughput; dual 2.5 Gbps WAN and LAN ports; USB 3.0 for storage and printer sharing; up to 3,000 sq ft of rated coverage; EasyMesh-capable.
Cons: Dual-band only — no 6 GHz; full WiFi 7 benefits in a busy household are stronger on tri-band routers; not 10G.
Is the BE400 Worth It?
At around $130 the TP-Link BE400 is the most affordable way into WiFi 7 in our guide. The combination of dual 2.5 Gbps wired ports, USB 3.0, EasyMesh and roughly 3,000 sq ft of rated coverage makes it a sensible router for households that want the new standard without paying tri-band prices. The trade-off is the missing 6 GHz band; buyers who need it should step up to the BE550 or another tri-band WiFi 7 router.
For everyone else it earns a recommendation. Compared with the BE550 reviewed earlier, the BE400 gives up the 6 GHz band but gains USB 3.0 and a lower price — a sensible choice for buyers whose client devices do not yet take advantage of 6 GHz. See also our best gaming routers guide.
Frequently Asked Questions
Is TP-Link a good brand for gaming routers?
Yes — TP-Link’s Archer and gaming lines offer strong value with WiFi 6/7, gaming QoS and reliable performance. Models like the BE400 (WiFi 7) bring next-gen speed at a sensible price for gaming and streaming.
Is WiFi 7 worth it without 6 GHz?
Yes, on compatible devices. WiFi 7 brings MLO and wider 320 MHz channels on 5 GHz as well, so a dual-band WiFi 7 router still improves on dual-band WiFi 6 hardware.
Does the BE400 have multi-gig wired ports?
Yes. It includes dual 2.5 Gbps wired ports (one WAN, one or more LAN), which is the key practical advantage over Gigabit-only routers.
Is the BE400 enough for a 2.5 Gbps broadband plan?
Yes. The 2.5 Gbps WAN port matches modern multi-gig broadband plans up to 2.5 Gbps with no wired bottleneck.
Does the BE400 have USB?
Yes. The BE400 includes a USB 3.0 port for sharing a storage drive or a printer over the network.
