Head-to-head
ASUS RT-BE82U vs TP-Link BE400: Count fast LAN ports and the nodes you own
The short answer
Choose RT-BE82U for several 2.5G local devices or supported existing ASUS AiMesh nodes. It has four 2.5G LAN sockets. Choose BE400 when supported EasyMesh equipment is already part of the home and one fast LAN socket is sufficient. Its other three local sockets are gigabit. Neither has 6 GHz. ASUS documents compatible USB phone tethering, while the reviewed BE400 evidence does not settle that feature.
Before you choose
The reasoning and the trade-offs
The second fast office device is where the port layouts separate
One 2.5G work computer fits either router’s fast LAN. Add a 2.5G NAS and BE400 has no second fast local socket, while BE82U has three remaining. In a small room without space or a spare outlet for another switch, BE82U can keep the complete local path simpler. If a suitable switch is already installed, the difference may be less important. Check the dock, NAS, cable and storage before expecting the router’s link rate to become a file-copy result.
What this is based on
A work computer plus a shared fast archive and limited room for extra hardware crossed with remaining multi-gigabit LAN count.
Main trade-off
TP-Link Archer BE400
One multi-gigabit local socket and no 6 GHz.
ASUS RT-BE82U
- Choose it for
- Connect a compatible 2.5G computer and NAS directly, with two fast local sockets left.
- Reuse supported ASUS AiMesh equipment or follow the documented compatible phone-tethering route.
- Main trade-off
- No 6 GHz and one USB socket.
TP-Link Archer BE400
- Choose it for
- Retain supported EasyMesh equipment after exact model and firmware checks.
- Use one 2.5G local endpoint when the other three only need gigabit.
- Main trade-off
- One multi-gigabit local socket and no 6 GHz.
About this comparison
ASUS RT-BE82U vs Archer BE400 for a wired home office. Compare the NAS path, AiMesh versus EasyMesh reuse and the requirements behind phone backup.
Both are dual-band Wi-Fi 7 routers with 2.5G WAN and four local Ethernet sockets. They compete for the same mainstream home upgrade, but those local sockets and existing mesh investments are not interchangeable.

What matters in practice
The differences that matter
The second fast office device is where the port layouts separate
One 2.5G work computer fits either router’s fast LAN. Add a 2.5G NAS and BE400 has no second fast local socket, while BE82U has three remaining. In a small room without space or a spare outlet for another switch, BE82U can keep the complete local path simpler. If a suitable switch is already installed, the difference may be less important. Check the dock, NAS, cable and storage before expecting the router’s link rate to become a file-copy result.
How we reached this conclusion
A work computer plus a shared fast archive and limited room for extra hardware crossed with remaining multi-gigabit LAN count.
The remote room can make the less flexible port layout the better purchase
If supported EasyMesh devices already cover the upstairs office or a bedroom, BE400 offers a documented route to retain that family. If the existing devices are supported ASUS AiMesh nodes, BE82U is the natural family match. Confirm the exact node roles and firmware rather than treating the word mesh as universal compatibility. Replacing otherwise useful nodes can matter more than a port-rate advantage at the main desk. A TP-Link Deco installation is a separate case and does not become Archer EasyMesh just because the logo matches.
How we reached this conclusion
Existing remote-room equipment plus a replacement router budget crossed with documented mesh families. Existing hardware changes the decision rather than a general brand preference.
The backup route must be verified before the broadband outage
ASUS documents phone tethering on BE82U with compatible hardware and firmware. That gives a buyer a concrete route to check if a workday backup matters. BE400’s reviewed USB storage documentation does not prove that it can or cannot do the same job, so confirm it before relying on it. BE82U has one USB socket, which is already occupied if it hosts a shared drive. The phone must also remain connected with suitable service. A feature list alone does not settle the household’s outage routine.
How we reached this conclusion
Workday continuity plus a shared USB drive and mobile phone ownership crossed with explicit tethering support and one direct USB socket. Unknown BE400 support remains unknown.

Meaningful differences
What changes the fit
| What changes | ASUS RT-BE82U | TP-Link Archer BE400 | Why it matters |
|---|---|---|---|
| LAN after 2.5G WAN | Four 2.5G. | One 2.5G and three 1G. | Same socket count, different fast-device budget. |
| Existing node family | ASUS AiMesh. | EasyMesh, model and firmware dependent. | Check the devices already serving the other rooms. |
| Radio bands | 2.4 and 5 GHz. | 2.4 and 5 GHz. | Neither adds 6 GHz. |
| Backup phone | USB tethering documented with compatible phone and firmware. | USB storage documented. Tethering unresolved in reviewed evidence. | Do not turn an unknown into an absent feature or an assured backup plan. |
What you give up
Every choice has a cost
If you choose ASUS RT-BE82U
- An existing EasyMesh installation needs a separate compatibility plan. AiMesh is not a universal mesh label.
If you choose TP-Link Archer BE400
- A second fast local endpoint can require another switch. Deco is a different family from Archer EasyMesh.
Recommendation switch
The decision flips if...
Several direct local connections need 2.5G
Choose ASUS RT-BE82U. BE82U has the required fast socket count.
Retaining supported EasyMesh equipment is the priority
Choose TP-Link Archer BE400. BE400 preserves that documented family.
What matters in practice
Before you choose
Keeping an existing mesh and connecting a fast NAS pair can favor different routers.
What this comparison cannot tell you
- No unverified cross-brand mesh compatibility claim.
- Missing tethering documentation is not proof of absence.
- No measured wireless or file-transfer result.
