Compact mobile router made by BUFFALO, with power adapter. - Brand: BUFFALO - Color: Black - Connectivity: Wired - Included items: Power adapter It seems to be often used as a repeater. It was installed on the first floor, with the optical fiber cable coming from the second floor. It is no longer needed due to moving. Thank you for looking. There are scratches on the main unit (though they do not affect functionality). The following is a product description from the manufacturer: <<This product is a high-power wireless LAN router that supports high-speed transfer of 11n/a450+11n/g/b450Mbps*. Because high-speed communication is available, you can make the most of high-speed line speeds such as optical fiber lines to enjoy downloading, transferring large files, and playing high-definition video more comfortably when connecting to the internet. The theoretical maximum value of the wireless LAN standard is 450Mbps, and it does not indicate the actual data transfer speed. A client device must also support 450Mbps to connect at 450Mbps. Please check the specifications for details on compatible client devices. The initial setting is 216Mbps (standard value).>>
