About the NEXT 1265WBTA wifi/bluetooth dongle

Just today i understood that all ROSE audio players can only be used with a single model wifi/bluetooth dongle available only in South Korea.

This situation renders the equipment i bought (RS520) partly useless.
The distributor/shop takes a long time to answer.
The distributor can not deliver a replacement for the NEXT 1265WBTA.
ROSE can not recommend compatible replacements because there aren’t any
There are no compatible alternatives on the market (Europe) which can be bought as a replacement.
What will happen if in a few years time the dongle breaks again and production has stopped?
I can not do anything…

What can be done to bring more safety to an investment into a audio player? I expect this equipment to function for a time range of 5-10 years inkl. availability of spare parts.

PS; as a temporary solution i attached an ethernet cable from the router to the RS520 to get a connection.

From Android;

A solution for a generic Bluetooth driver in Android is described here. Sure there is one for wifi/bluetooth dongles as well.
Would that be the way to integrate any wifi/bluetooth dongle in Rose devices not just a single model from one manufacturer?
