Я недавно унаследовал сеть, полную оборудования Ubnt. Одна из проблем заключается в том, что радиомодули случайным образом появляются в логах радиостанции:

В это время я заметил 2 другие радиостанции и удалил их с той же проблемой, но проблема продолжает возникать. Прошивка представляет собой смесь версий, но все v8.7.1XI интересно, сталкивались ли другие пользователи с подобной проблемой "зомби-отключения" радиостанции, потому что приходится удалять радиостанцию практически каждый день, и это немного утомительно.
