Connection lost

I purchased a pair of MA2500Ds and liked the fact that the bandwidth is transmitted almost completely end to end.

Unfortunately every now and then I have a disconnect that lasts about 30 seconds, 1 minute.

I've read that others have the same problem as me.

The firmware version is 2.0.12.

I see that you have published a new version 2.0.13: will it correct the disconnection problem?

I thank you cordially.
