Netgear Orbi AX6000 RBR850 won't connect with a TP-Link TL-SG108-M2 Switch
Hello. I have a brand new Netgear Nighthawk 2.5Gbps Cable Modem with Voice (CM2050V) using Xfinity 1.2Gbps service and a Netgear Orbi AX6000 RBR850 that both work great on their own with Nighthawk ...
Computer networking is indeed confusing. Notice the diagram on the modem Product Data Sheet, page 3:
https://www.netgear.com/images/datasheet/networking/CableModems/CM2050V.pdf
The modem can be connected directly to (a) your computer [not a switch leading to computers] or (b) a WiFi router.
When the computer is connected directly to the modem, you should see the full 1.2gb bandwidth. one 2.5gb ethernet port talking to another 2.5gb ethernet port.
Of course, none of us want to connect only one computer. We have a whole house full of devices.
The Orbi RBR850 WAN port is also 2.5gb, so the direct connection between the modem and Orbi should reach your contract speed of 1.2gb. https://www.netgear.com/images/datasheet/orbi/RBK852.pdf
Please look at the Speedtest on the RBR850 and see what it reports.
Alas, now that 2.5gb has reached the Orbi, there is no way to get more than 1gb to any device. The router etherent ports are all 1gb, which will product a maximum speed test of about 920mb. The newer (and ghastly more expensive) RBRE960 has a 2.5G port on the LAN side plus the usual 4 gigabit LAN ports. https://www.downloads.netgear.com/files/GDC/RBKE963/RBKE963_DS.pdf
It is probably not much consolation to have internet capacity available to other devices even when the computer is consuming nearly a full 1gb if the goal was to eat up the entire 1.2gb with the computer and leave zero for the entire rest of the house.
CrimpOn I just wanted to say thanks. Everything you said was exactly right and well educated. I suppose it addresses my main concern as untenable with my current equipment. At least I can return the TP-Link Switches but I appear stuck with the RBR850s. Of course, not a bad thing as you've implied, the RBR850 set are very nice and I'm sure I'll get years out of them. Also, thanks for clarifying the 1Gbps limit on the Orbi RBR850 LAN ports. Its always frustrating when marketing uses half-facts to mix the truth and confuses the consumer. Foolishly I believed it was a 4 Gbps per the marketing. My own fault for not drilling into the data sheet fineprint as you shared. I do have a delimna though as I would have preferred an ultra-high-speed internal network for transfering home data around. I already got the Veto from the beancounter (wife) about upgrading to the 9xxx series as you said its quite expensive.
Would you happen to be familiar with the Netgear AX6000 WiFi Cable Modem Router (CAX80) and know if it would support both a multi-gig highspeed network and Xfinity Tripleplay? Getting crosseyed trying to read the fineprint here: https://www.netgear.com/media/CAX80_with_Spectrum_DS_30Mar21_tcm148-120183.pdf but it seems to still suggest it contains Four (4) Gigabit Ethernet LAN ports and – Dual Gigabit Ethernet port aggregation which I'm not sure what that means in simple English. I suppose also concern if the wireless network would be compatible with the Orbi mesh or if they'd bump into each other.

My sense is that the TP-Link switch would be the perfect component for an "ultra-high-speed internal network", but I see one significant obstacle: apart from the 2.5G ethernet card in the PC, what other devices are likely to support greater than gigabit speed? Most NAS systems have only gigabit ethernet ports, although maybe some of them can do "link aggregation" to bind two ports together and get a higher connection rate. (But, I do not know if the TP-Link switch supports link aggregation.)
I am not confident that having *something* with a higher speed ethernet will accomplish much. What can absorb that much bandwidth?

Alas, I have no experience withthe CAX product line. It is obviously a replacement for the cable modem and the Orbi WiFi router.
To be perfectly honest, I have little experience relevant to the discussion: (a) my own internet is a measly 200mbs from Spectrum, which appears entirely adequate for my needs, (b) I have exactly zero devices which support WiFi 802.11ax (i.e. WiFi 6). and do not anticipate owning any in the next year or so.

The CAX80 supports Link Aggregation (LAG) on the LAN side.
https://en.wikipedia.org/wiki/Link_aggregation
So you can connect up two ports to one device that also support LAG and get higher bandwidth data flow.

FYI, Standard practice of connecting modems and router together is Cable modem > Orbi > Switch. When Orbi is in router mode. If Orbi is in AP mode, then you can connect a switch in between the modem and Orbi.
Netgear has set up a community forum specifically for the Orbi AX (WiFi 6) products. Most of the people who watch that forum are more likely to have experience with Orbi AX and know how to work it better than those of us who follow this "general Orbi" forum. Might be more likely to find someone who has a solution if the question is posted there:
