One of my minidoges (connected to litecoinpool) keeps disconnecting from my network.
Everything looks fine but every 10 minutes it disappears from find.goldshell
Any ideas
Upgrade to the latest firmware. See the following video from VoskCoin here

Hi Javier
Update your firmware to 2.1.4 download Goldshell or Github.com/goldshellminer
then go to Goldshell backend go to system and disable Wi-Fi but stay connected with ethernet cable that should do it had the same problem with mine and this solved it
