Sharp Wireless Lan Adapter Wn8522b Driver May 2026

If you're unable to find or install the driver for your Sharp Wireless LAN Adapter WN8522B, consider:

If you are trying to revive an older Sharp laptop (such as the Sharp Actius series) or a Sharp-branded mini-PC, you may have encountered the Sharp WN8522B Wireless LAN Adapter. This internal mini-PCIe or CardBus Wi-Fi module was common in Sharp devices produced around the mid-to-late 2000s.

However, finding the correct driver for the WN8522B can be frustrating, as Sharp’s official support pages have largely been taken offline. Below is everything you need to know—from hardware identification to installation.

The Marvell 88W8335 is supported by the libertas kernel module (though reliability is poor on modern kernels). sharp wireless lan adapter wn8522b driver

sudo modprobe libertas

Check lspci -v for 11ab:2b55. If detected, the system may load libertas_sdio or libertas_pci. You may need to compile an older driver backport.

Because printers are often entry points for network vulnerabilities, the WN8522B is equipped with robust security protocols:

Some Sharp Actius laptops (e.g., PC-RD30, PC-CS30) included the driver on a recovery partition or disc labeled “WLAN Driver WN8522B”. If you're unable to find or install the

No. Sharp never released macOS drivers. However, using the generic Realtek RTL8188CUS driver for Mac (via Homebrew or the “Wireless USB Adapter” app from Realtek) may work, but AirDrop and Continuity will not function.

The WN8522B almost certainly uses a mass-produced chipset. The safest way to get it working on a PC is to identify the chipset via the Hardware ID.

Steps to find the Hardware ID (Windows): Check lspci -v for 11ab:2b55

If the ID starts with 0BDA (Realtek): Download the driver directly from Realtek’s official site for the RTL8188 series. If the ID starts with 148F (Ralink): Download the MediaTek (who bought Ralink) legacy driver.

A few WN8522B units actually contain a Broadcom BCM4306 chip. Try the Broadcom 4306 (Dell TrueMobile 1300) driver if the Marvell driver fails.
