Добрый день! Помогите понять в чем трабла: Приобрел плату arduino-ethernet-shield - https://amperka.ru/product/arduino-ethernet-shield Установил на UNO3. Но сконфигурировать так и не получилось. Вывод в монитор порта: 0.0.0.0 Failed to configure Ethernet using DHCP 255.255.255.255 connecting... 255.255.255.255 255.255.255.255 255.255.255.255 connection failed disconnecting.
