SXS80 2.5G LAN Ethernet Port 1 - Link speed limited to 1000 Mbps?
Hi, I am using a NAS (Synology DS1823xs+) that is connected via a CAT8 ethernet cable, from the NAS’ LAN 3 port (10GbE) to the LAN 1 port (2.5GbE) on a Netgear Orbi Pro 6 Satellite (SXS80) with the l...

I could most likely connect Port 1 on the router (2.5G LAN) and Port 1 on the satellite (2.5G LAN), and it wouldn’t surprise me if the link speed is then reported as 2500 for both devices.
And no, it won't limit the Internet speed to 1G, check the wonders of a LAG.:

But even if that is the case, then wouldn’t that mean that Port 1 on satellite is somehow limited to 2.5G when directly connected to the router? Am I the only one that expects Port 1 on the satellite to function as a general LAN port that can be linked to other devices than the router?
All ports as well as the LAG assigned to the LAN (read not assigned to WAN usage) are universal ports
To understand where the development is going to, look at the consumer Orbi Quad-Band Mesh WiFi 6E system network ports. I admit (to avoid wrong expectations) it's by far not as flexible as I would prefer: Unless I'm wrong, the 10 GbE port can not be re-assigned to LAN usage.
For the router, if port 2 is set to WAN (which is limited to 1G), and you connect your modem to that port, then I don’t see how your internet speed would not be limited to 1G…? I know what LAG is, but I don’t see how that would come into play. Or do you mean that you would have your modem connected via two Ethernet cables to port 2 and 3 on the router, and then bind those ports? But even if you do that (which I don’t think would work), then LAG doesn’t increase speed for a single device (and doesn’t work with WAN?), it only increases the throughput when using multiple simultaneous connections/devices. So you would still be limited to 1G in either case..?
But this is getting a bit off topic. Let’s completely forget about the router for a moment and focus on the satellite. This thread is solely about the port 1 (2.5G LAN) of the satellite not providing 2.5G speeds in my testing. The router and internet speeds etc are completely unrelated as far as I’m aware
By the way the SXR/SXS80 quick start guide labels the ports a bit differently. The text description talks about port 2-5 being 1G, and the image shows that the ports are numbered in reverse order (from 5 to 1). To clarify though, I am trying to connect the NAS (10/5/2.5 GbE) to the port on the left side (which I have been referring to as "Port 1" in this thread), which is labeled as "2.5G/1G". So the port highlighted in red in the attached screenshot is only providing a link speed of 1000M in my case.

no, of course not. Major ISP (CPE manufacturer) as well as Netgear are have devices - cable modems and routers - in the market allowing to use two GbE links in a LAG providing aggregated bandwidth to the Internet router >> 1 Gb. It's just a question on how the LAG members are distributing the traffic over the ports. There a no algorithms defined in the "IEEE 802.1AX-2008 IEEE Standard for Local and Metropolitan Area Networks – Link Aggregation", all it say is:
This standard does not mandate any particular distribution algorithm(s); however, any distribution algorithm shall ensure that, when frames are received by a Frame Collector as specified in 5.2.3, the algorithm shall not cause
a) Misordering of frames that are part of any given conversation, or
b) Duplication of frames.

This seems to be specific to the interoperability of the Orbi Pro 6 2.5 GbE port (satellite or router is irrelevant) with the Multi Gig port - the only one you are testing with - on your NAS.
- I’m not really getting why you are focusing on the theoretical capability of setting up a WAN LAG with ports 2 and 3 for a modem (which I doubt would even work as you describe - but that is besides the point) and the SXR80 router. It really is completely unrelated to the issue I am facing. Let’s please stay on topic
To simplify the issue, I would just like to know how someone would be able to use the full 2500 link speed on port 1 (2.5GbE) of the SXS80 satellite, as I seem to only be getting 1000M when connecting to a device that should support 10/5/2.5/1G, using a CAT7/8 Ethernet cable. That is all…

I might be wrong, but from looking at the consumer Orbi WiFi 6 (AX6000) System (850 and 860 series) my understanding is that neither of those models have satellites with anything above 1GbE LAN ports.
It seems as if the only AX6000 variant with a 2.5GbE LAN Port on the satellite is the Orbi Pro 6 (SXR/SXS80). If so the SXS80 is unique in that regard.
I think the only consumer model with a 2.5GbE LAN port (satellite) might be the WiFi 6E (AXE11000) / 960 Series (?)
Sorry, my bad: Had the RBSE950 and 960 satellites with the 2.5 GbE in mind.
