Here is a detailed breakdown of its core specifications:

On 5GHz networks, the RTL8852BE can reach near-gigabit speeds, making it ideal for streaming and gaming.

The PSREF (Product Specifications Reference) for Lenovo devices lists the component as (note the Bluetooth version may vary to 5.2 depending on the specific laptop model) [1†L18-L20][11†L9-L10].

While Wi-Fi 5 supported downstream MU-MIMO, Wi-Fi 6 enables both uplink and downlink MU-MIMO. The 2x2 configuration on the RTL8852BE ensures efficient data transmission even when other devices heavily load the router. Target Wake Time (TWT)

Uncheck . C. Change Wireless Mode

If you own a modern Lenovo laptop (Legion, IdeaPad, or Yoga series), chances are you’ve met the . On paper, it sounds like a champion: WiFi 6, 802.11ax, Bluetooth 5.2, and PCIe interface.

Up to 1201 Mbps on the 5 GHz band using 80MHz channel widths.

For enthusiasts demanding maximum throughput, low latency gaming, or access to the 6 GHz bands offered by Wi-Fi 6E and Wi-Fi 7, the Realtek RTL8852BE can be physically upgraded.

The Realtek RTL8852BE provides excellent day-to-day performance for streaming, office work, and casual gaming. If you own a Wi-Fi 6E router and require access to the less congested 6 GHz wireless band, upgrading your Lenovo card to an Intel AX210 is a cheap, physically compatible DIY project. Otherwise, keeping the RTL8852BE updated with official Lenovo drivers will serve you perfectly.

With a 2x2 MIMO configuration, the RTL8852BE can utilize two spatial streams to download and upload data. When paired with a Wi-Fi 6 router, this prevents your laptop from waiting in a queue behind data-heavy devices like smart TVs or streaming boxes. Target Wake Time (TWT)
