BUFFALO Buffalo Wi-Fi Router AirStation WNR-5400XE6P [White]

[Product details]

◆ Tri-band router with Wi-Fi 6E support and increased usable frequencies
- Supports three frequency bands: 2.4GHz, 5GHz, and 6GHz
This product is a tri-band router that can use Wi-Fi on three frequency bands.
In addition to the commonly used 2.4GHz and 5GHz bands, it is compatible with the newly available 6GHz Wi-Fi band.
While connecting to conventional devices, it is also possible to simultaneously connect to newly available Wi-Fi 6E-compatible devices.

Less congestion and interference
Wi-Fi communication in the 6GHz band is only possible via the high-speed Wi-Fi 6 connection.
Therefore, there is no risk of slower devices monopolizing communication speeds, as is the case with the 2.4 GHz and 5 GHz bands, resulting in slower speeds.
In addition, since it is a newly opened band, it is an available frequency band, so it is expected to be less susceptible to interference and less likely to experience speed reductions.
*The explanation is theoretical, and the actual communication speed will vary depending on the product and environment.

- No waiting time due to DFS
DFS stands for "Dynamic Frequency Selection."
The 5GHz band is used by weather radar, aviation radar, and other radar waves. If your Wi-Fi router detects this, it must change channels and stop Wi-Fi for 60 seconds to monitor the new channel to make sure there are no radar waves in the new location.
This mechanism is called DFS.
In the 5GHz band, communication can be interrupted depending on the channel, but since radar waves are not used in the 6GHz band, communication interruptions due to DFS waiting time do not occur, allowing for smoother communication.
*The explanation is theoretical, and the actual communication speed will vary depending on the product and environment.

・Increasing options for high-speed transmission
Wi-Fi 6E adds the 6GHz band to the 2.4GHz and 5GHz bands, increasing the number of channel options available for communication.
For example, in the 5 GHz band, there were only two channels to choose from for 160 MHz high-speed communication, but with the addition of the 6 GHz band, it is now possible to choose from three new channels for 160 MHz high-speed communication.
With Wi-Fi 6E, the number of channel options available for communication increases, making it easier to select a channel without interference, resulting in smoother communication.
*The explanation is theoretical, and the actual communication speed will vary depending on the product and environment.

◆ Supports Wi-Fi 6E for high-speed communication

・Wi-Fi 6E routers improve wireless throughput by approximately 1.4 times
Replacing your Wi-Fi 5 (11ac) router with a Wi-Fi 6E (11ax) router is expected to improve wireless throughput.
If you replace the previous model WSR-2533DHPLS (11ac generation) with this product, you will achieve speeds approximately 1.4 times faster in the 5GHz and 6GHz bands (theoretical values).
*To communicate in the 6GHz band, your device must also be compatible with the 6GHz band.

・More simultaneous connections
With the previous standard, communication was conducted sequentially with each terminal, requiring a waiting period.
OFDMA, a new feature of Wi-Fi 6, allows communication with a large number of devices at the same time, so everyone can enjoy the internet without having to wait.

・Smartphone power saving
Supports TWT (Target Wake Time), which controls the standby time of devices such as smartphones to save battery life.
*The device must also be compatible.

・Wideband 5GHz/6GHz 160MHz compatible
Computers and other devices that support wideband 5GHz/6GHz are compatible with 5GHz/6GHz 160MHz, which is twice the channel width of conventional models.
It is now possible to transmit large amounts of data, such as video streaming, more stably.
*The device must also be compatible.

◆ Equipped with "Band Steering Lite" function
Equipped with a "Band Steering Lite" function that judges the signal strength between the device and automatically switches between the long-range 2.4GHz band and the faster 5GHz band.
You can communicate comfortably anywhere in the room.
*Some devices have fixed band priorities, so you may not be guided as expected.
*The "Band Steering Lite" function does not support switching to or from the 6GHz band.
Depending on the operation of the device itself, it may switch from the 6GHz band to the 2.4GHz/5GHz band (or vice versa).

◆ Equipped with an INTERNET port capable of communication up to 2.5Gbps
This product is equipped with an INTERNET port that supports up to 2.5Gbps.
It supports high-speed communication services exceeding 1 Gbps, which are becoming more and more popular every year, allowing you to enjoy internet communication without sacrificing line speed.

◆ "Wi-Fi EasyMesh (TM)" that easily realizes mesh network
EasyMesh automatically selects the optimal communication path.
Even if the current communication route becomes unavailable or slow, a faster route will be selected and communication will be continued.
This ensures a stable connection even if the radio wave environment changes.
