Realtek RTL8180, RTL8185, and RTL8187SE PCI Wi-Fi adapters
An early generation of Realtek 802.11b/g wireless chips that shipped on PCI and Mini-PCI cards in budget desktops and laptops during the early-to-mid 2000s. They only do 2.4 GHz station and ad-hoc modes, and were common in retail Wi-Fi cards around 2003–2006 before being superseded by newer Realtek families.
recommendation
Worth keeping but flagging as legacy hardware. The chips have not been sold new for nearly two decades, yet the code is not abandoned: a memory-leak fix was still being backported to stable kernels as recently as January 2026, and OpenWrt continues to ship the module for users with old PCI cards. No newer in-tree driver covers these PCI IDs, so removing it would strand the remaining users without a replacement.

The driver still receives real upstream maintenance activity: a rtl8180 memory-leak fix was backported to stable in January 2026, indicating ongoing bug-fix attention rather than abandonment.

LKDDb maps CONFIG_RTL8180 to Realtek RTL8180L, RTL8185, and RTL8187SE PCI devices and lists many early-2000s retail cards, confirming the family and its legacy PCI/PCMCIA deployment pattern.
- openwrt.org
OpenWrt still packages kmod-rtl8180, which is evidence of some continuing downstream deployment, but as an optional legacy kernel module rather than mainstream new hardware.
- driverguide.com
Third-party archived RTL8180L driver packages date to late 2003, which supports the conclusion that the hardware family is from the early-2000s era and not a new-sold 2025 product line.
codex reasoning notes (technical)
Local `rg`/`sed` on the tree showed this directory handles RTL8180, RTL8185, and RTL8187SE PCI chips and only station/adhoc 2.4 GHz operation. `lore_activity` on `drivers/net/wireless/realtek/rtl818x/rtl8180/dev.c` returned January 2026 stable backports, so the code is old hardware but not dead code; that argues against deprecate/remove. Web search opened LKDDb and package-index results; LKDDb and the archived 2003 RTL8180L driver page support that the hardware peaked in the mid-2000s and is not still sold new in 2025. OpenWrt packaging suggests residual legacy use, so deployment is best classified as low. No natural in-tree replacement driver covers the same PCI IDs; newer Realtek drivers are for different chip families.
