I’ve got two MiBox’es with the same issue.
They’re connected via Ethernet and when I try to connect to VPN, the internet disconnects.
They’re using different USB to Ethernet adapters and it’s on two different networks (different locations in Auckland). Exact same issue!
I understand that this isn’t only for MiBox’es, but happens for a lot of Android boxes and with different VPN providers (I’m using NordVPN).
I’ve created a ticket with NordVPN, but as this seems like it’s a general issue, not with a specific VPN provider, I thought I would ask if anyone else have experienced the same issue and if they’ve found a fix?
It works perfectly well via WiFi, just not Ethernet. And as the WiFi isn’t the best, I really would like to have it connected via Ethernet.
