Motola mb8611 speed capped at 1gig?

@flatlander3​ thx for the response- actually there are 3 hidden ports, and other literature on their website says the single port is capped at 1gig- I’m confused! https://help.motorolanetwork.com/hc/en-us/articles/115004178154-FAQ-There-is-only-one-Ethernet-port-on-the-back-of-my-MB8600-I-want-to-use-port-bonding-How-do-I-access-the-three-other-ports-

@bajanjack​  That's the MB8600, not the MB8611, and you'd need the LAG firmware (link aggregation) even if the hardware existed, which it probably doesn't in the MB8611 version according to the marketing spec sheet in the link I posted above.  

What you should know about this device’s 2.5 Gbps:

Ethernet LAN port
This very fast Ethernet LAN port helps you get maximum
performance from high-performance routers and
computers that support this high speed. If you use a cable
Internet speed above 1 Gbps, a LAN port of only 1 Gbps
can reduce actual speeds. Some cable modems aggregate
two Ethernet ports to address this problem, but a single
2.5 Gbps LAN port is far superior to LAN port
aggregation. This cable modem also supports 1 Gbps and
100 Mbps LAN supports, so it’s fast and flexible.

Peel the sticker.  See if the hardware is even there I suppose.  Log into the web interface and see if there is actually a LAG option for ports 3 and 4 if there is.

@flatlander3​ thank you for correcting me on the ports- very helpful. A bit more help if you can- I have the eero 6 plus routers which are capped at 1 gig. When I test the direct wired speed of the modem it comes in at 955 Mbps, the same speed I had with my previous 1 gig plan before changing to my current 1.2 gig plan. Is the direct wired speed limited by the eero routers? I’ve been thinking the routers are bypassed, but it looks like I could be wrong. By the way, just fyi, I am very happy with my current speed- I’m getting 600 Mbps to my iPhone. Several weeks ago the Xfinity agent suggested I change to the 1.2, and it’s more about getting some benefit from the change, though negligible.  My upload max did go from 24 to 40+. You’re the first person who corrected me on the ports, and that includes Motorola techs- I really appreciate that. 

Well, there is always driver and OS overhead on anything, so right off the top a 1Gbps Ethernet port is typically a ~950Mbps port.  WiFi 6 can be really fast if you are close to the access point/Gateway.  WiFi 5 is slower at the same distance.  600Mbps on WiFi is really decent.  Wouldn't change anything there.

In the real world (not a speed test), what matters is who you are trying to pull content from and where they are, what is in the middle, what that content is and the protocol, how they are distributing it, what they do for load balancing on their end, plus the application you are using.

That's not going to be the result you see on a speed test.  Your millage will vary. 

If you are going to try for 1.2Gbps or better with a faster plan than that, then that 2.5Gbps port on the Motorola would have to plug into another 2.5Gbps port "on something" that could deliver that bandwidth to something else, be that more 2.5Gbps Ethernet ports for clients/devices, or perhaps splitting up that bandwidth among some WiFi clients that when aggregated together could use that bandwidth doing different things.

@flatlander3​ Thanks. So… my eero 6 plus rated at 1 gig is also capped at that when it’s hard wired?
