USB Port GT-AX11000 ???

Hey all! Hope people will see and comment on this thread. Not sure how active this forum is vs maybe another networking-only type forum is, but here goes!

I have the ASUS ROG GT-AX11000 router and it's worked fine for the last 1yr+. I have a 1200mbps down & 40mbps up internet plan from Xfinity. I spent way too much time and energy of my life trying to get those speeds to my desktop PC through the GT-AX11000. I now finally receive the hardware limitations of the device and how I'll never be able to achieve those speeds without more than just the one single 2.5g port on my ASUS router. Meaning, I can plug the ethernet (CAT8) from the modem's 2.5g port into the 2.5g port on the AX11000 just fine, but then all other ports henceforth are capped at 1g. I'm actually considering selling this router as it's mostly useless to me in that regard - I can't access the full speeds I'm paying for, so it's a waste. I've been eyeing the "lower" model new AX6000 as I've heard great things AND it has more than one 2.5g port. I'm 99% sure that'll allow me to get what I pay for. Alas, I want to try one last thing... the USB port!

In fact, ASUS makes this USB-to-Ethernet adapter: https://www.asus.com/Networking-IoT-Servers/Wired-Networking/Wired-Adapters/USB-C2500/







I might be the only person in the world to be curious about this or try it, but what if I keep that same config I just laid out, except instead of using one of the 1g capped ethernet ports on the router to my desktop PC's 2.5g ethernet onboard port, I try using the USB 3.0 port on the AX11000 as an OUT and then plug the USB-Ethernet adapter there, THEN run that ethernet cable to my 2.5 Realtek onboard port on my ASUS Crosshair VIII motherboard?

It's a lot cheaper than a new router (i.e. AX6000), so I might give it a whirl just to see. But curious if anyone's tried it or thinks it technically could be achievable or if there's some limitation or inability I'm overlooking...

So the link aggregation combines 2 1 G trunks which the S33 should support, (product video implies 3.5 Gbps through the two ports at the very end). BUT the OP just needs his 1.2 G service to get through, so the extra 0.8 Gbps is covered by overhead? Definitely worth a shot:

https://www.asus.com/support/FAQ/1039053/

My modem provides a 2.5 G connection to my AXE16000, but my service provides maximum 1075 Mbps on speed test, lots of overhead room my meaning....


OP is already able to get full Internet bandwidth *when shared among multiple clients*. LACP will not change that. There is no way to get the full bandwidth to a single client.

As for the USB adapter, as noted previously it would depend on driver support. So I would buy it where it can be easily returned.

Thank you for clarifying. That's a bummer. Since that is the case it may be futile to try the USB ethernet dongle at all...

Hey all, not sure why I didn't see any of these posts before now. Thought I had email notifications turned on. Sigh. Anyway, I appreciate each and every one of the comments/posts. I'll try to hit the highlights:

Yes, my ISP plan (Comcast/Xfinity) is a 1200mbps down and 40mbps up package. That's what I pay for. Not sure if I said it already before, but if I connect my ARRIS S33 modem directly via good CAT cable to my desktop PC (2.5g RealTek onboard port), I can get speeds easily OVER my 1200mbps plan. I have seen speeds as high as 1400mbps with that setup. Now, the further I move away from a connection arrangement like that, the slower speeds I get. Historically, I could never crack 1gbps (1000mbps) since that's what all the ports are capped at on this expensive fancy GT-AX11000 router.

It's funny, I actually started trying to "professionally" learn about computer networking, etc. I'm taking some college-level courses and want to get some certifications in the IT world. So things are slowly starting to make a little bit more sense for me vs what I was posting over a year ago on this forum about this same issue.

As far as any link aggregation/bonding etc, it was my understanding that is out of the picture with the S33. Now, had I kept my SB8200 or whatever I had previously, I could have used those two 1g Ethernet out ports on the modem to two Ethernet in ports on the ASUS router and enabled Dual WAN in the settings blah blah blah. Since that ship sailed as I thought I was "upgrading" by purchasing the S33.... kinda gave up on that lol.

It only recently started to dawn on me how silly or dumb it was for ASUS to advertise or market this router with just the 1 single 2.5g ethernet port as there's not a lot you can do with just 1 port (duh)... and yes, there are actually those of us who have over a 1gbps ISP connection and want to take full advantage of that. I realize routers of today mostly (and the past) still usually cap at 1gbps, but that's slowly changing IMHO. I think we're going to see 2.5g and 5g and even 10g Ethernet ports on home routers very soon (some are already here).

Knowing what I know now, I wish I spent the money on a different ASUS router. In fact, I'm considering ditching this entirely if I can sell it for a few bucks... I'm leaning towards going with a full Unifi Dream Machine Pro setup with wireless access points. That seems to be way more professional-grade geared and probably just as good if not better than anything ASUS has. I don't know. I'm still learning.

Anyway, as far as the USB 2.5 Ethernet adapter situation, it works! I am finally able to break over the 1gbps wired speed to my desktop! I have it looking like this:

ARRIS S33 modem 2.5g Ethernet out ----> 2.5g-USB-Adapter ----> into USB 3.0 port on ASUS GT-AX11000 then -----> 2.5g WAN ethernet out port on AX11000 -----> into 2.5g unmanaged switch ------> out via ethernet to -----> RealTek 2.5g ethernet port in on my ASUS Crosshair Hero VIII motherboard/desktop PC. And boom, just like that, I can finally see over 900mbps whatever it was capped at previously. I wish the latency/ping was a little better. Not sure what that's all about. Maybe something to do with using the USB vs a traditional ethernet cable to the router, who knows?

If I'm not mistaken that speed test is from the router out? Are you logging into the router pages and using the speed test there?

(Yes I do not get notification of responses on this forum for some reason as well).

IF that is the router speed test then there's some loss vs testing with just the 2.5 G modem out to 2.5 G AX11000 port in? What is the speed in that configuration?

Brilliant idea to connect it the way you did by the way. Thank you for sharing!

There's a video on the S33 pages on the www.surfboard.com site. I took a screen capture of the moment it shows evidence of being able to Dual WAN/WAN Aggregate.

As far as the USB connections, I looked at the USB section on the user interface of the AXE16000. The only WAN option appears to be the one below.

3G/4G
Switch to USB mode to use a 3G/4G USB wireless dongle or Android phone as a USB modem.


The 1200 Mbps us a strange speed for the ISP to supply. I have a 400 Mbps connection which normally downloads at 480 Mbps, so some overage is normal.

As far as I know, we have not found someone with a 2.5 Gbps connection to verify the 2.5 Gbps WAN/LAN port will actually use that speed.

Agreed, 1.2Gb a bit strange in my opinion. My arear where I stayed either 1, 2 or 10GB. whereby 10Gb price too far out of reach.

1200 is a multiple of 400 and the OP saw 1400 at times, which is a close multiple of 480....

There's 2 G symmetric service available at our new to us house in San Dimas. Still trying to convince the significant other to get it. Here at our current home maximum is 980 down 880 up or something like that.

We pay for 1 G but getting 1075 per router speed test running the 2.5 G connection. (I tried it on a 10 G port but modem connects at 2.5 with that as well).

I was thinking OP may want to try connecting USB on LAN side, never thought of the idea to try connecting on the WAN side, which notes "dongle" as an option. Where's my dunce cap?....
