@SrDarkWarrior I'm not going to install it right away. I'll wait for your experience first. :-)

@David-TP Hi, David, thanks for the information. Have the problems with reduced internet speed been solved?

@David-TP Thanks for your comment. You're not going to believe it, but since the downgrade to 1.5.6, the speed is back to normal! The downgrade finally succeeded. I will never update to 1.6 again....

I have performed the downgrade. But the Deco with firmware 1.5.6 cannot connect to the internet.... the Deco with Firmware 1.6 does..... Very annoying all this.

@David-TP I still have the speed drop issue. Downgrading to the previous firmware is not possible. When will there be a solution?

@David-TP The speed has dropped since the update to 1.6. I'm doing the speed test through the main M9 deco. QOS is at 1000/1000mbps. When I do a speed test through the app I get this result.
