This is a wireless LAN router made by ELECOM. It supports dual-band 5GHz and 2.4GHz. It's a compact size, about the size of a palm, and can be placed vertically with the included stand. The instruction manual, AC adapter, stand, and box are included. Please prepare a LAN cable separately. I have confirmed that it can be accessed without any problems from a Windows 11 device.
