Texas Instruments WiLink 8 (WL18xx) Wi-Fi chipsets
Texas Instruments WiLink 8 family of single-chip 802.11n Wi-Fi (and combo Wi-Fi/Bluetooth) modules, such as the WL1835MOD and WL1837MOD, commonly soldered onto industrial gateways, point-of-sale terminals, medical devices, and embedded ARM boards from the mid-2010s onward.
recommendation
It should stay because the hardware is still sold new by TI in 2025 (the WL1837MOD module is listed as active and orderable), OpenWrt still ships matching firmware for real-world deployments, and the code itself received substantive upstream patches as recently as late 2024. Volume is low and the silicon is aging 802.11n, but no other in-tree driver covers these chips, so removal would strand existing embedded products.

Upstream wl18xx saw substantive linux-wireless work in 2024, including firmware-status support, so the driver is not abandoned.
- lore.kernel.org
wl18xx was still being mechanically updated with core driver-API changes in late 2024, indicating it remains part of maintained code paths rather than a removal target.

TI lists WL1837MOD (WiLink 8) as ACTIVE and orderable, showing wl18xx-class hardware was still sold new in 2025.

TI's part-detail page shows active commercial availability for a WL1837MOD orderable part.

OpenWrt publishes a wl18xx firmware package, which is evidence of ongoing real-world embedded deployments.
codex reasoning notes (technical)
`drivers/net/wireless/ti/wl18xx` is a real kernel driver directory; local Kconfig identifies it as TI WiLink 8 support. I used `lore_file_timeline` on `drivers/net/wireless/ti/wl18xx/main.c`, which showed 2022-2024 activity including a substantive 2024 wl18xx feature patch and no removal-thread evidence in the returned history. I attempted `lore_regex` and `lei` for removal/deprecation discussion; `lore_regex` timed out and `lei` could not start in the sandbox, so I did not rely on them. I used web search to obtain the TI product and part-detail URLs showing WL1837MOD marked ACTIVE/orderable, plus the OpenWrt package URL showing wl18xx firmware still shipped. Net: aging 802.11n embedded hardware with low-volume industrial use, but still sold and still seeing upstream maintenance; no natural in-tree replacement driver covers the same chips.
