Orbi speeds on RBS850 are much slower since switching to Fiber Internet with Nokia modem

Could check into some power line adapters in between the RBR and RBS if you think that might help. Have see other post about using them. 

I forgot about power line adapters. I actually think I have some already but need to see what the ratings are. I would assume I would want to at least have a 1GB pass through. I am not sure the 2GB would be needed since my Orbi lan ports are capped at 1GB. I was comparing TP Link AV1000 and AV 2000.

One other question I reviewed the connection diagrams and I see you can daisy chain them. So I could use power line adapters between RBR850 and my workout room new RBS850. Then I think I can use the ethernet that is available between the Workout Room Satellite and the Master Bedroom Satellite. But then, could I rely on the wireless connection between Master Bedroom Satellite and the Living Room Satellite in room below?  Or would I need power line connection between Master Bedroom and Living room to maintain the daisy chain?

Could PL from the RBR to the 1st RBS, then if you have ethernet between the 1st RBS and 2nd RBS, ethernet connect them here in between, would be a daisy chain. 

Something to give a try with and see. 

The Power Line solution did not work so I just decided to pay a contractor to run ethernet line to my workout room. I am getting about 800 download and 900 up on that direct ethernet connection which now is going into my newest satellite. I also have a hard wire ethernet connection to my master bedroom satellite. I recorded a direct connected speed into my laptop of the ethernet in master bedroom of 765 up and 916 down. So that one is now plugged into that satellite in master bedroom. 

Is there something I need to do in regards to rebooting the Orbi router and re-syncing to get full advantage of the now hardwired connection from my Orbi router to workout room satellite then hard wired to master bedroom satellite? My living room satellite still has to connect wirelessly.  

The orbi app shows that I am hard wired on the two previously mentioned satellites.

The Orbi should figure out that the connections are 'wired' and you need do nothing.

p.s. Although the Orbi 'app' is colorful and 'modern', my preference is to double check important details with the Orbi web interface. If Attached Devices says the connection is Good - Wired, then I believe it.

Thanks, I did double check on the web admin app and noticed the one in my master bedroom was back to a wireless 5GHZ. Then noticed it was the same on the phone app. So I power cycled that satellite and re-synced it and it is back to wired on the two upstairs satellites again. 

So I will continue to monitor it and hopefully it improves some speeds around the house on wifi. 

Thanks again for all the help.
