RBK852 devices connected through ethernet ports are slow.

Problem solved. 

Connecting the ethernet wire from RBR 850 to RBS 850 must be the last step of the set up.

First I made sure the RBR setup is complet while RBS is not connected to the power. Connection speeds: Laptop wired: 950Mbps, I-phone XmaxS 650 Mbps in the same room.

Then I factory reseted the RBS and synced wirelessly with RBR 35 feet away.

After the Blue light on RBS is turned off and my  I-phone Xs Max showed 400 Mbps, then I connected the in wall Cat 6 Ethernet wire from the cenral room where ONT, RGW and RBR 850 are. The wired backhaul method gave higher wifi speeds than the wireless  backhaul. On I-phone Xs Max I got 600-650  Mbps. All the devices connected to the back of RBS are fine and my HTPC desktop  2 floors down gets 950-1000 Mbps.

My phone still gets 250 Mbps 2 floors away. Is this sattelite stronger than RBS50?
