I own a mr550 router. The last firmware update is dated December 6, 2023. Instead, the mr 500 router has benefited from two firmware updates in 2024.

I don't understand why this difference.

What can I do to improve the performance of my mr550 that has the disconnection problem?

I also don't understand why on the log in page it is recognized as a mr500.

Thanks to anyone who can answer
