Want to inform about device support for ZBT-Z8103AX-C has become official for SNAPSHOT release. ZBT-Z8103AX-C is available in Firmware Selector. Please take care to include LUCI package, as SNAPSHOT releases don’t add it per default.
Owners of ZBT-Z8103AX-D may give firmware ZBT-Z8103AX-C a try. The model D appears to use very same motherboard as model C by looking at and comparing pictures found here in the forum.
