Thank you for viewing. I am introducing the Buffalo Wi-Fi Router WSR-2533DHPLS-BK. It is no longer needed due to a change in internet service providers. I used it for about a year (and it was working perfectly fine). I apologize for the incomplete removal of stickers, etc. There are no instructions. It is as shown in the photos. (The included LAN cable will also be included) There are no instructions or warranty. Please consider this if you understand. Main product features from the manufacturer's website: ● Compatible with major Japanese IPv6 services Supports IPv6※( IPoE / IPv4 over IPv6). ※A separate contract with a provider is required to use IPv6 services. ● 4x4 & Beamforming function This product supports "Beamforming" and "Beamforming EX," which improve transfer speed and stability by identifying the position and distance of the client devices and delivering radio waves appropriately. ● Supports "MU-MIMO" for simultaneous connection to multiple devices Supports "MU-MIMO," which enables simultaneous communication with multiple devices. ● Four antennas widely cover devices in various orientations and angles The four antennas are efficiently arranged, so you can comfortably use them for SNS vertically, watching videos horizontally, and of course, while lounging around. ● Fully utilizes "optical fiber" - all ports support "Giga" All ports, both internet and LAN, support 1000Mbps Giga. There is ample transfer speed, allowing you to fully utilize the speed of optical fiber internet. ● Easy setup with a dedicated app on your smartphone Download the smartphone/tablet app "QRsetup," scan the included QR code, and follow the guide to complete the initial setup. You can start using the internet just by operating your smartphone. ● Supports stronger security "WPA3" Supports the new Wi-Fi security standard "WPA3 Personal," which blocks unauthorized password decryption with stronger security.
