I noticed a significant drop in download speed on my Decos after recent firmware update to 1.4.4. Both 2.4 GHz and 5 GHz bands are affected.

Normally wifi on my modem/router is turned off, Decos are in AP mode.

Topography is modem/router->Main Deco via ethernet cable->Slave Decos via wifi

If I switch off Decos and connect directly to wifi on my modem/router, I get around 86-94 Mbps down and 35-38Mbps up. Before the upgrade, I was getting these speeds with Decos as well. The link is 100/40 Mbps.

After firmware upgrade to 1.4.4, I am getting 48-55 Mbps downloads on Decos. I get these from speed tests on Ookla, choosing the nearest server. When I use the Deco app speedtest, it gets better results, but I don't think they are relevant.

I tried downgrading via the web interface to the older firmware, but the downgrade wan't allowed.

Please helpt to downgrade or fix the slow speeds.
