Firmware name: hk.t.rt2861v09
Chipset: Realtek RT2861 (802.11n 2T2R MIMO, PCIe / SoC interface)
Typical use: Routers, access points, industrial wireless bridges
The RT2861 is a relatively old (late 2000s) but still deployed chipset for 2.4 GHz 802.11b/g/n. It requires a firmware binary loaded by the host driver (usually rt2860sta or rt2800pci in Linux).
Before you download a file labeled "HK.T.RT2861V09 firmware," you must verify your hardware. hk.t.rt2861v09 firmware
Warning: Do not rely on the TV brand name alone. Manufacturers often switch internal boards between production batches. A 32-inch Skyworth TV from 2020 might use a V06 board, while the exact same model from 2021 might use a V09 board. If the sticker does not match the firmware file, do not proceed.
The V09 suffix indicates a specific board layout/GPIO configuration. Key characteristics: Firmware name: hk

The RT2861 chipset is 802.11n, 2.4GHz only, with a maximum link speed of 300Mbps (theoretical). In 2025, this is obsolete. Real-world throughput struggles to exceed 60-80Mbps. Moreover, many modern routers optimize for 5GHz and 802.11ac/ax, leaving 2.4GHz congested. Before you download a file labeled "HK
You should keep this firmware only if:
For any daily-driver PC, upgrade your wireless hardware.
If your device’s hardware ID (in Device Manager) includes PCI\VEN_1814&DEV_0601 or PCI\VEN_1814&DEV_2861, you are dealing with the RT286x family, and hk.t.rt2861v09 is relevant.
