2.5gb wired network with Orbi 750
I have a wired 2.5gb wired lan setup, modem then router rbr750 to 2.5gb switch 150ft to another 2.5gb switch in my garage to rbs750 and for some reason it shows a 2nd sat that has a different Mac and uses ip of 192.168.1.250 and my network is setup as 192.168.0.0 network it works fine with no problems but it adds that 2nd sat and it shows wireless when it’s wired and wired when it’s wifi so if I wire the sat in the garage the fake sat show wireless and vise versa. I have 3 sats and the other 2 work fine all run through 2.5gb switch the to sats is it that the 1 sat is running trough 2x2.5gb switch’s that it does this ? I have moved sats around and all do same thing . My 2 sats in the house 1 wired rbr750 to 2.5gb switch to 1gb switch to sat other sat is wifi soon to be wired through 2x2.5gb switch’s so might have same problem again will see.

Seems like a ethernet mess.
What is the Mfr and model# of the ethernet switch in the configuration?
What CAT# cabling are you using? For 1Gb connections since the RBS are only supporting of 1Gb max, CAT6 UTP is recommended.
Try connecting the 3rd SAT directly to the back of the RBR to see how it appears on it's web page. If all RBS are ethernet connected, they should all appear as wired RBS. Status should show GOOD as well.
IF you tested each RBS at this one location with this one switch, possible this one switch could be the problem.
Idle curiosity: What prompted the installation of 2.5G Ethernet switches? All of the Orbi 750 units have only gigabit Ethernet ports, so they derive no benefit from higher potential speed. Do other devices on the network require higher speed? Or, is this an example of future proofing? (buy higher speed switches now so that when new devices are purchased, the network will already be in place)
The default Orbi LAN is 192.168.1.x Was there a specific reason to selet 192.168.0.x instead?
One experiment might be to bring the garage satellite into the same room as the Orbi.
Power it up and let it connect to the router over WiFi.
Verify that it appears with a correct IP address and shown as WiFi connection.
While still running, connect it to the router with a short Ethernet cable.
Verify that it (eventually) changes to a 'wired' connection with a correct IP address.
(I, personally, prefer to assign IP addresses to my satellites in the LAN Setup table)
Then, move it back to the garage and hook it up to the switch before powering it on.
- I have a media server 2.5gb and all my computers use 2.5gb so it’s for faster file transfer between them and helps when I’m streaming from the server at home and some one like my dad is streaming at his house but mainly for file transfer on the lan I only have 1 gbs internet so not the end of the world if my garage only had 1gb but just didn’t seem right that it was working fine but had a extra sat for some reason
- I’ll fine out soon but it works fine hooked to 1gb switches but I’ll be doing the same set up with the last sat tomorrow and if it does it again with this one then it has to be the 2.5gb switches but if it doesn’t then it’s the long run of cat 5 I know not made for 2.5 gb or it’s the switch in the garage
Thanks for explaining about the high traffic servers. Perfectly reasonable.
My guess is that the the switches will handle the Cat5 cable issue themselves when they auto negotiate their connection.
This is built into the Ethernet hardware which the user has no control over. Cat5 is not rated for gigabit to 300ft (as Cat5e and Cat6 are), and I have not seen reports of "how far" it will support 2.5G.

Wondering if you have had a chance to run that experiment with the garage satellite. Would help me resolve an unusual hypothesis. 150ft (plus building walls, etc.) is a long way for a WiFi connection. My guess is that the router and satellite will not connect over that distance even at 2.4G. My hypothesis is that when the satellite is booted up, it starts up the WiFi and looks for a connection. Damn. No router. Well, when there is no router, I will just be 192.168.1.250.
The posts so far have not mentioned the specific brand/model of 2.5G switch. If it is a managed switch, it might be possible to log into the switch and learn what speed the switch has negotiated with that garage switch.
