Set of 2. Powers on. The only included accessories are those shown in the images. No smokers in the household. There is yellowing due to sun exposure. It was working until October of last year, but it stopped working after switching to au Hikari? Rental router? It worked with J:COM, NURO Hikari, and SoftBank Hikari (NTT lines) in the past.
