The Wis09abgn is not the name of a manufacturer but rather a model identifier for a wireless network adapter. In most cases, this device is a low-profile USB Wi-Fi dongle or an internal mini-PCIe card that supports dual-band wireless N frequencies (2.4GHz and sometimes 5GHz).

When you plug in or boot a device with this adapter, Windows 10 uses a driver to communicate with the hardware. Without the correct driver, the adapter may appear as an "Unknown Device" in Device Manager or be missing entirely from the network adapters list.

The Samsung WIS09ABGN LinkStick is a dual-band wireless USB 2.0 adapter originally designed for 2009–2011 Samsung Smart TVs and Blu-ray players. While it was intended as a proprietary TV accessory, many users have discovered that its underlying hardware—the Ralink RT2850/RT2870 chipset—makes it a highly capable Wi-Fi adapter for modern PCs.

Getting the WIS09ABGN driver to work on Windows 10 requires a bit of manual effort because Samsung does not provide official PC drivers for this device. How to Install WIS09ABGN Driver on Windows 10

Because Windows 10 may not automatically recognize the LinkStick as a network adapter, you must "force" it to use compatible drivers. The most reliable method is to use the built-in Windows driver for the Linksys WUSB600N, which shares the same internal chipset.

Plug in the Adapter: Insert the Samsung LinkStick into a USB 2.0 or 3.0 port on your PC.

Open Device Manager: Right-click the Start button and select Device Manager.

Identify the Device: Look for an item under "Other devices" or "Network adapters" labeled 802.11 n WLAN or similar with a yellow exclamation mark.

Update Driver: Right-click the device and select Update driver.

Manual Selection: Choose Browse my computer for driver software, then select Let me pick from a list of device drivers on my computer.

Find the Manufacturer: Scroll down the list of device types and select Network adapters. Select Compatible Driver: In the Manufacturer column, select Linksys.

In the Model column, look for Linksys WUSB600N Wireless-N USB Adapter with Dual-Band ver. 2.

Note: If you don't see it, uncheck "Show compatible hardware" to see the full list.

Confirm Installation: Windows will warn you that the driver might not be compatible. Click Yes to proceed.

Restart: Once the installation is complete, your adapter should now appear as a functional Linksys WUSB600N in your network settings. Alternative Driver Sources

If the built-in Windows drivers do not work, you can download third-party driver packages that specifically target the Ralink chipset used in the WIS09ABGN. Go to product viewer dialog for this item.
