Hi, I would suggest you could hold on for a while before downgrading the firmware.

It would be highly appreciated that you could help me check some details:

1. Do you still remember the original firmware before the 1.5.7 upgrade, 1.5.3/1.5.4/1.5.5?

2. Did this satellite unit turn red when the connection dropped?

3. Could you please refer to this link to change a different Deco as the main Deco to see if it is always this unit that dropped the connection?

4. May I know who is your internet service provider and how about the internet connection type, dynamic IP, or PPPoE?

Thank you very much.

Hi, it is not a known issue and I paid more attention because it is a new firmware and just released less than a month.

I noticed that you seemed to downgrade the firmware back to 1.5.3.

So would the instability issue disappear?

If yes, I would love to forward your case to our senior engineers for further assistance.

Thank you very much.
