I am selling products I no longer use to upgrade my home network configuration. Purchased from Amazon Purchase Date: July 28, 2023 Purchase Price: ¥49,475 (2 Deco units) Purchase Price: ¥2,099 (1 wall mount unit) Purchase Price: ¥850 (Ankluy CAT8 LAN cable 2m) Usage Period: Approximately 1 year and 6 months I had no problems and was comfortable using it during the usage period. Device management (turning mesh off and fixing connected Decos) was very good because it could be done intuitively with simple operations from the smartphone app. I was dissatisfied that I couldn't create separate 5GHz/2.4GHz networks because it is a tri-band device. I have discarded the outer box and the included instructions. I will pack it with cushioning material and tape to protect it from impact during shipping. Before listing, I measured the 5GHz band speed, and it was 403.2 Mbps download and 393.0 Mbps upload (NURO Hikari Mansion type, around 10 PM). It has been initialized using the RESET button. (The app screen photo is from before initialization) I appreciate your understanding if you are purchasing a used item.
