There is some paint peeling, but overall, it is in good condition. Of course, it can also be used in ordinary homes. It is A5 size, small and lightweight, and operates very fast and stably. Power consumption is less than 11W if the USB port is turned off. In addition, simple monitoring is possible for free by using NEC's cloud service, NetMeister. What is being sent is "the main unit only." A power cable is not included, but a C13 cable, which is common for desktop PCs, can be used. Settings are basically done from the console, such as serial connection or SSH, but basic items can also be configured from a web browser. It is equipped with tunnel functions such as DS-Lite (Rakuten Hikari, etc.) and MAP-E for IPv4 over IPv6 technology, and VPN processing is also fast, so it can be used for internet connections in ordinary homes, as well as for connecting domestic corporate locations to the FLET'S network at a low cost and high quality. The latest firmware, 10.6.21, is the main one, and 9.4.17 is in the backup area. Manufactured in May 2023. It is recommended to get a newer one because it has a built-in battery to maintain non-volatile memory. YAMAHA is also good, but the NEC IX is also excellent.
