Please read the profile before purchasing for a smooth transaction. This is a BUFFALO WAPM-APG300N wireless LAN access point for corporate customers. It's a business model known for stable communication and high durability, suitable for building networks in offices, stores, and other locations. This listing is for the main unit only. 【Condition】 Listed as junk due to missing outer case. The outer plastic case was removed for better heat dissipation. Therefore, as shown in the photos, the metal casing is exposed. It was operating normally until it was removed during a system replacement, and I have confirmed power-on via PoE (power supply via LAN cable) for this listing. There are scratches and wear overall due to use. Please consider this only if you understand that the original case is missing. 【Recommended Points】 Since the outer case is missing, the heat dissipation is excellent, so how about using it as a test unit in an environment where heat tends to build up, or installing it in a back room or ceiling where appearance doesn't matter? It's still a corporate model, so the internals are solid. You can use it cost-effectively for parts or experiments.
