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...
For link speeds higher than 1000BaseT, auto-negotiation is mandatory. Or does Syno break this standard and has an option to select a fixed link speed like 2.5G or 5G on these adapters? That much about the ***** idea to ask if Netgear has a way to force 2.5G on the port 8-)
FYI there is in fact a setting to change the WAN port speed (for the router, by switching between port 1-2), so it wouldn't be too farfetched to imagine there being a similar setting for the satellite. But as you point out, the link speed would normally be determined by auto-negotiation. So I am guessing the auto-negotiation on the Orbi simply doesn't work. Or perhaps the 2.5G LAN Port 1 on the Satellite was never capable of 2.5G to begin with (despite the documentation claiming that it is). UntilI I see someone show that their Insight device management page is actually reporting that port as "Link Speed: 2500M/Full" then I have my doubts 🙂
Hi
We are checking this issue internally. will get back to you soon.

- Many thanks, Bruce. Much appreciated!
BruceGuo After contacting Synology again, I have received conflicting information regarding whether the NAS supports 2.5G or not. The first support agent supposedly quoted the network configuration file for the exact model that I am using, which states that 2500baseT/Full (and 5000baseT/Full) is supported. But the second support agent is telling me that it isn't, and that he has no idea where the first support agent managed to find that information. That being said, the fault may be due to the NAS, rather than the Orbi Pro 6 Satellite. I will continue trying to press Synology for a definitive answer regarding this and post an update once I have confirmed that the NAS is working as expected or not
- Amazing support cultures in this industry 8-)
Unless my evaluation is fundamentally wrong, and we don't face a dual network adapter designated E10G18-T2 with two Marvell Aquantia AQC 107 here, there should be no systematic reason to fail Multi Gig link speeds. Things can differ based in the adapter chip firmware on-board in a Flash, set un place during the adapter manufacturing. Read there are more factors than just the driver implemented in the Syno OS. Just read-out the theoretical possible link speeds isn't really useful...
Granted, there are adapters built on the more reliable Inhell X550 or decent x710 chipset, also supported by Syno - but much more expensive (about 100 USD higher at least), too.
Connect the SXS satellite direct to the SXR router port - and you will see the 2500mbps link speed. Of course, you might state the indication is fake.
This is not the first and not the last interoperability issue you will experience in your life.
No idea why some people bring in such a negative attitude here ...With about a decade the Marvell Aquantia AQC-107 NIC is in the field, there had been many interop and reliability issues
- Which ports are you suggesting to connect? Port 1 on the satellite (2.5G LAN), to port 1 on the router (2.5g WAN)? Or do you mean port 1 on the satellite (2.5G LAN) to port 2-5 on the router (1G LAN)?
In either case, I don’t see how doing either of those things would help address the issue. I only feel your odd negativity towards Synology, I don’t mean to bring any negativity here. I’ve been a fan of NETGEAR for years, and I’m just a bit surprised that the port 1 on the satellite is not working as I expected. Other than that, the Orbi Pro 6 has been working amazingly for several month, so I’m happy with the purchase (and NETGEAR in general). 🙂
I might either be doing something very wrong, or as mentioned perhaps this issue has gone unnoticed for some 3 years without anyone reporting it. If someone comes forward and shares that they have a similar setup, and that they are getting the full link speed (2500), then that might help in troubleshooting what I’m doing wrong. But so far your only suggestion has been that the NAS is probably not functioning, or that I should connect the satellite to the router (which again I have no idea what that would aim to accomplish?).
I’ll wait for Bruce and the team to have a look at this. Hopefully we can find out what the cause of the issue is and how to solve it

Or do you mean port 1 on the satellite (2.5G LAN) to port 2-5 on the router (1G LAN)?There are not that many 2.5G available. And you clearly know how to assign the 2.5G WAN port to be used as a LAN port.
Said this, I'm not a big fan of these hard labels. The industry would do much better just putting numbers 1..5.
