This is a wireless LAN router made by ASUS. It was released quite a while ago, but its performance is quite good. It has 8 ports on the local side and 2 ports on the internet side, allowing it to perform load balancing. It's a bit overkill for personal use, and seems to be more geared towards small to medium-sized businesses. I used it at home without a second thought. I'm selling it because it's about time for it to retire from active duty, so I bought a replacement. There is a defect where the base of one antenna is loose, but otherwise, I haven't found any particular problems. I bought it from Amazon Outlet and it has been working for about 5 years. ASUS has a monitoring app for smartphones, which is quite interesting just to watch. The photos of the app are from a similar ASUS router. There's almost no difference in the screen.
