The RTL8723BE is notorious under Linux. The mainline kernel includes the rtl8723be driver (staging driver for many years), but it suffers from:

Because the chip lacks 5 GHz support, it is highly susceptible to interference from neighboring Wi-Fi networks, microwave ovens, and USB 3.0 devices. In dense apartment buildings, performance collapses. The RTL8723BE is notorious under Linux

The chip uses one transmit and one receive chain (1T1R). With 40 MHz channel bonding and short guard interval (SGI), its theoretical link rate reaches 150 Mbps. Real-world throughput is typically 60–90 Mbps, limited by the single antenna and 2.4 GHz interference. (examples – expand as needed) The chip uses
The Realtek RTL8723BE is a highly integrated, single-chip wireless LAN (WLAN) and Bluetooth 4.0 controller that interfaces via the PCI Express (PCIe) bus. Introduced as a cost-effective solution for entry-level and mainstream laptops, it supports the 802.11n standard on the 2.4 GHz band. While widely deployed, the RTL8723BE has garnered a reputation for inconsistent performance and driver-related difficulties, particularly on Linux-based operating systems. This paper examines the technical specifications, architectural features, performance characteristics, and known operational challenges of the RTL8723BE.
Where possible, replacing the RTL8723BE with an Intel or Atheros mini-PCIe card yields dramatic improvements in stability, range, and throughput.
