Thank you for viewing. I am selling this because I no longer need it due to replacing my computer. I used it for about 9 months, and it was working without any problems until today (January 3, 2026). I don't think there are any noticeable scratches. The antenna angle and direction can be adjusted, which is convenient. I initially purchased a sub-unit without an antenna, but the connection kept dropping, so I bought one with an antenna. When I changed the angle and direction of the antenna and tested it on a speed test site, there was a difference in the results, so I thought it was good that I bought one with an antenna after all. (Please note that connection speed depends on various environments and peripheral devices.) The following is a description provided by Mercari AI.
