Sharp Wireless Lan Adapter Wn8522b Driver -
The Sharp Wireless LAN Adapter WN8522B is a specialized USB dongle designed primarily to bring internet connectivity to Sharp AQUOS LED TVs. While it is a reliable piece of hardware, finding the correct driver or getting it to work on modern operating systems can be a challenge. Understanding the WN8522B Hardware
The WN8522B was originally bundled with specific Sharp AQUOS TV models to enable DLNA streaming, Netflix, and firmware updates. Inside the casing, it typically utilizes an Atheros or Ralink chipset, which is why some generic drivers occasionally work. However, the official software is designed to bridge the gap between the TV's proprietary OS and your home network. How to Install the Driver on Windows
If you are trying to use this adapter on a PC rather than a TV, you will likely need to manually point Windows to the correct files.
Plug in the device: Insert the WN8522B into a USB 2.0 or 3.0 port.
Open Device Manager: Right-click the Start button and select Device Manager.
Locate the Adapter: Look for an "Unknown Device" or "802.11 n WLAN" under "Other devices." sharp wireless lan adapter wn8522b driver
Update Driver: Right-click the device and choose "Update driver." Manual Search: Select "Browse my computer for drivers."
Compatibility: If you have the original setup disc, point the search to the CD-ROM drive. If not, you may need to download a legacy Atheros AR9285 or AR7010 driver package, as these are the chips often found inside the WN8522B. Using the Adapter with Sharp AQUOS TVs
For most users, this adapter is intended for a television. If your TV does not recognize the WN8522B, it is usually not a driver issue but a setup error.
Firmware First: Ensure your TV firmware is updated via an Ethernet cable before switching to wireless.
USB Port Selection: Use the USB port labeled "Wireless LAN" or "USB 1" on the back of the TV. The Sharp Wireless LAN Adapter WN8522B is a

Device Not DetectedEnsure the adapter is pushed all the way into the port. Because the WN8522B is wide, it sometimes hits the TV bezel, preventing a full connection. Using a short USB extension cable can solve this.
Connection DropsThis adapter operates on older Wi-Fi standards. If your router is set to "5GHz only," the WN8522B will not see the network. Ensure your router has the 2.4GHz band enabled.
Windows 10/11 IncompatibilitySince this is a legacy device, Windows 10 and 11 may block the driver due to "Memory Integrity" settings. You may need to disable this in Windows Security to allow the older driver to load. Technical Specifications Interface: USB 2.0 Standards: IEEE 802.11 b/g/n Frequency: 2.4 GHz Security: WEP, WPA, WPA2 Summary Checklist Check if the chipset is Atheros-based for PC use. Use a USB extension to avoid physical interference. Enable 2.4GHz Wi-Fi on your router. Install legacy drivers for Windows 10/11 compatibility.

The Complete Guide to the Sharp WN8522B Wireless LAN Adapter: Drivers, Installation, and Troubleshooting
Overview
The Sharp WN8522B is a wireless LAN adapter commonly found in older Sharp notebook laptops (e.g., Sharp Actius series). It is based on a Realtek RTL8187L or RTL8185 chipset. Microsoft Windows does not include native drivers for this adapter.
Important: Sharp no longer provides official support or driver downloads for the WN8522B. The most reliable solution is using the reference driver from Realtek.
Final Verdict: Should You Bother?
Yes, if:
- You are using Windows 7, XP, or Linux.
- You need a basic 2.4GHz connection for legacy hardware.
- You enjoy the challenge of reviving old tech.
No, if:
- You are using Windows 11 as your daily driver.
- You need stable, high-speed internet (this adapter caps at ~20-25 Mbps real-world).
- You are not comfortable manually forcing drivers.
The Bottom Line: The Sharp WN8522B is a piece of wireless history. While no official drivers exist for modern Windows, the generic Ralink RT2870 driver provides a lifeline. However, given the security vulnerabilities of older Wi-Fi standards and the low cost of modern adapters, your best long-term solution may be to retire this adapter and upgrade to a current USB Wi-Fi 5 or Wi-Fi 6 dongle.
