ESP-01 избирательно подключается к wi-fi

[vityab3]

ЕСП-ха не хочет подключаться к роутеру. Но легко подключается к НЕКОТОРЫМ телефонам.
Заметил, что если на телефоне сменить канал точки доступа с первого на 11-й то есп перестает ВИДЕТЬ сеть.
Если после этого вернуть на первый -- перестает подключаться.
ЧТО ПРОИСХОДИТ?
