BUFFALO wifi router AirStation White WXR-1901DHP3 Purchase price: 15,530 yen This model can be used over a fairly wide area. I've been using it for about 6 years, and it still works without any problems. There is a crack at the base of the antenna, but it doesn't affect the operation. It hasn't been initialized, but it can be done easily, so please take care of it. If you need it, I will also include a LAN cable, so please comment.
