I have 3 Deco XE75, the main deco is connected via ethernet to Starlink gen 2 router (with the ethernet adpater).

When I connect all my devices to the deco, I get around 40Mbps

When I connect 1 device directly to Starlink router, and all the rest to deco, I get on the devices connected to deco 250-400 Mbps and the device connected to Starlink is getting 150-200 Mbps

I tried the same in bypass mode. In that mode all devices got 40Mbps.

For some reason if there is one device connected to Starlink the whole system is working much faster. Is there an option to connect all devices to Deco and still get the higher speeds?
