Realtek RTL8192SE/RTL8191SE 802.11n PCIe Wi-Fi
An early 802.11n PCIe and mini-PCIe Wi-Fi chipset from Realtek, commonly soldered into budget and mid-range laptops around 2009-2012. It was a single-band 2.4 GHz part that disappeared from new systems once newer Realtek and Intel Wi-Fi chips took over in the mid-2010s.
recommendation
Worth keeping but flagged as legacy because the hardware is commercially obsolete yet still turns up in older laptops that people run Linux on today. The code is not abandoned: a 2025 linux-wireless cleanup touched it and a firmware-loading fix was backported to stable in March 2025 with Realtek's Ping-Ke Shih acking it, so it still receives genuine maintenance. No newer in-kernel driver covers these PCI IDs, so removing it would strand the remaining users.

linux-wireless saw a 2025 patch touching rtl8192se as part of rtlwifi maintenance, showing the driver still receives upstream attention.
- lore.kernel.org
A rtl8192se-specific firmware-loading fix was backported to stable in March 2025 and carried Ping-Ke Shih's Acked-by, indicating ongoing bug-fix relevance.

LKDDb identifies CONFIG_RTL8192SE as support for Realtek RTL8192SE/RTL8191SE PCIe 802.11n adapters and lists the supported PCI IDs.
- linux-hardware.org
linux-hardware shows the RTL8191SEvB/rtl8192se device still appears in modern user probes, but as legacy notebook hardware rather than new platforms.
- deviwiki.com
DeviWiki mirrors the chipset family as in-kernel support for RTL8191SE/RTL8192SE, consistent with an older 802.11n-era PCIe laptop WLAN part.
codex reasoning notes (technical)
Real driver directory confirmed locally via exec_command/rg: module_pci_driver in sw.c plus PCI IDs 10ec:8192/8171/8172/8173/8174. lore_activity on sw.c returned 2025 linux-wireless maintenance and 2025 stable backports, so this is not abandoned and I found no positive evidence of an active removal series within the tool budget; that argues against deprecate/remove. Web search found LKDDb for exact hardware scope, linux-hardware for present-day field sightings, and DeviWiki for chipset family context. The hardware looks commercially obsolete: 802.11n-only mini-PCIe laptop WLAN silicon from the early 2010s, with current sightings confined to old systems; the 2012 date is an inference from that era/profile rather than a direct vendor EOL notice. No upstream replacement driver covers the same chipset, so replacement_driver is null; keep the driver but annotate it as legacy/low-deployment.
