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. While Wi-Fi 5 supported downstream MU-MIMO, Wi-Fi 6
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)
