Backhaul 1 gb not 2.5gb
I have an 870 system. One satellite. When I connect the satellite to my switch, it connects at 1gb. The switch and my network is 2.5gb.
The ports are all supposed to be 2.5gb but I am not seeing that.
Any ideas?

Brand and model# of this switch?
Be sure your using good quality CAT LAN cable. CAT6A STP is recommended.

I get that but I can't control what is in the wall. This is not new construction.

Possible what is IN the wall maybe older CAT LAN cable and causing the speed reduction.
To check this in a quick fashion, take one or both RBS and directly connect them to the back of the RBR. Check the RBRs web page for BH connection speed. You should see 2.5Gb speed for each RBS connected behind the RBR. IF you see this, then your issue is in wall cabling and or the switch.

This is correct. All the Ethernet ports on the 871 router and 870 satellite are combination 2.5GB/1.0GB/100Mb ports. They are supposed to autonegotiate the correct speed when connected to another Ethernet device. https://en.wikipedia.org/wiki/Autonegotiation
What is the brand/model of the 2.5GB switch?
How are you informed that the satellite has connected at 1GB rather than 2.5GB?
(does this information come from the switch? the satellite? the router?)
If the satellite is temporarily relocated to the same room as the router and connected with an Ethernet cable (i.e. no switch), what happens?

How far is the satellite from the switch?
Is it practical to try another cable?

Too far to try that, but I will move the satellite close and ensure it works with a known short cable. It could be the wiring in the walls but it is less than 100 feet and should fine. Other devices are using the built in wiring without difficulty.

Are any of these devices also multigig? If so, is it practical to move one to the satellite location for testing?
Is the cabling cat 6 or better?
