Hello all, I have a RBR850 router and two RBS850 satellites. The second satellite was added a few weeks ago, and since then (but it might be unrelated) my macbook stopped connecting to the 5GHz WIFI and only connects to 2.4 GHz.

When the Mac goes to sleep and comes back, I always have to refresh the connection (disconnect/reconnect)

On the mac, I have tried every single suggestion available:
- Forgetting network and adding it again;

- Deleting WI-FI service and re-adding it;

- Removing configuration files.


On the Orbi system I tried to:
- Reduce power output of 2.4GHz channel;
- Lock the channels of both 2.4 GHz and 5 GHz channels;

- Disable 20/40 MHz Coexistence.

On the same room I have different devices that connects to the 5Ghz WIFI such as my mobile and my PS5.
