ASUS RT-AC86U last Merlin fw. 384.19 upload speed problem

[Saiyan10]

Hi, i have bought this router recently, and i have 600 MB upload /download speed on my network.

When I test my connection in stock firmware I get full upload/download speed, but, when I have installed Merlon fw 384.19 and i make a test, the upload speed is limited to 30 (with ethernet and wifi connection).

If I install the stock fw I recover the connection speed.

I have not configure anything.

Can anyone help me with this problem?

thank you.

Did you do a Hard Factory Reset after flashing 384.19?
