Realtek RTL8723BE 802.11n PCIe Wi-Fi Adapter
A single-stream 2.4 GHz 802.11n PCIe Wi-Fi plus Bluetooth 4.0 combo chip that Realtek introduced around 2013 and that shipped in large numbers of budget laptops, especially from HP, through the mid-2010s. It predates 802.11ac and is still found in repair-channel replacement mini-PCIe cards sold today.
recommendation
Worth keeping but worth flagging as legacy hardware. The chipset is more than a decade old and largely confined to aging laptops, yet the driver still attracts genuine upstream maintenance, including a 2023 fix for an ASPM problem specific to RTL8723BE on certain Intel PCIe bridges and routine cleanups as recently as 2025. Replacement cards remain available as spares, so removing it would strand working hardware, but new deployments are rare.

The driver directory still received upstream maintenance touches in 2025, showing it is not abandoned.

The driver saw a chipset-specific functional fix in late 2023 (ASPM quirk for RTL8723BE on some Intel bridges), indicating real bug-fix traffic rather than only dead code churn.

RTL8723BE is a highly integrated 1T1R 2.4 GHz 802.11n PCIe WLAN plus Bluetooth 4.0-era combo part, indicating an older pre-802.11ac/ax laptop chipset family.

Replacement RTL8723BE cards were still being sold as new retail stock in 2026, but marketed mainly as spare parts for older HP systems rather than current platforms.
codex reasoning notes (technical)
Lore evidence first: `lore_file_timeline` on rtl8723be/sw.c returned 2023-2025 activity with no removal discussion, including a 2025 constification patch and a 2023 RTL8723BE-specific ASPM fix. Local `rg` on rtlwifi Kconfig/Makefile confirmed this is a distinct PCIe 802.11n adapter driver. Web search found an old RTL8723BE datasheet and a current retail replacement-card listing; together they indicate 2013-era hardware still sold in repair channels, but no sign of meaningful new-platform deployment. Hence `keep-annotate`: legacy hardware, low current deployment, but still maintained and not under active removal.
