Hi,

I have a 1200 megabits package from Comcast. (1.2 Gbps) I have the modem which has an ethernet cable plugged into the 2.5 cable in back of my S33 Arris Surfboard. Home computer. Desktop win 11. Is what I have.

The problem is that I can't seem to get Multi gig speed when I run speedtest.net. I get 947.68. I have the ethernet cable going from the 2.5 port on the back of my modem too the Multi gig ethernet port on the back of my Netgear Night hawk rax120.

Then I have the 5 g ethernet port selected in the router settings. Under wan setup. Then I have another Ethernet cable plugged into port 1 on the switch because left is for 2.5 and right is for 1gig or 100M So the other end of the cable plugged into port 1 on the switch is going to the back of my desktop plugged into a 10 gig Ethernet card.

And then I have yet another ethernet cable this being a cat 7 and the other 2 are cat 8 plugged into port 2 and the other end is plugged into the Wan intenet port the yellow port on the back of the router. and when I run speedtest.net I only get 946.68. So I don't get the over gigabyte speeds which is why I bought this router. Yes I pay for this speed of 1.2 with My comcast Internet provider.

And if I connect an ethernet cable going straight from the back of the cable modem to the back of the computer plugged into the 10 gig ethernet card Bypassing the router and the switch of course I just got the switch today. Then I will get Multi gigabit speeds showing on speedtest.net which would be 1,447.89. So Could you maybe tell me if I have the cables in the wrong places. Or what seems to be the problem My huch would be that I have to bypass the Internet Wan port the yellow one on the router somehow because that's only 1 gig. But the internet was not finding a dns when I bypassed it and had nothing plugged into it. Is there a way to bypass the Internet port on the router. I believe that is why I'm still seeing only 1 gig in speed or close to it when I run speed test. Because of course the internet port on the router is only 1 gig. And I think in order see the 1,446.78 for a speed from speed test I have to be connected to only multi gig ports and nothing else.



Any help would be awesome

Welcome to the scam routers being sold. From someone else having a similar problem on a different brand of router I think there are no consumer grade routers that can run over 1gbit. I don't think any of the wifi chipset vendors are selling chipset/cpu that can do this so no router maker has it.

To work you need 2 ports at least that can run over 1gbit a wan and at least 1 lan. I have not been able to find one, I thought maybe microtik sold one but I now have my doubts after looking around.

The largest misinformation on these routers is that you can combine 2 1gbit ports to get more speed using port aggregation. That tends to not be true except for very special traffic types like torrent and even then it is pure luck if it works. The port aggregation algorithim selects path based on a math equaltion based on ip and ports. It does not actually look at utilization or do fancy stuff like balance by packet. This means it can put all traffic on a single connection and leave the other unused. It also always sends the traffic for a single session over the same port so a single download can never use more than a 1gbit port in this case.

Maybe someone knows of a router with multiple ports that are 2.5g or faster, but last time I looked I could not find one. Maybe drop your plan back and save some money until a router become available.

Note although not your issue it is highly likely the cables you are using are fakes. Cat8 cables are only used in high end data centers and are extemely expensive. Cat7 cables were never fully certified. What you want is cat6a cable for up to 10gbit. Even then be careful many cables claim this but are not actually ethernet cables at all. Check that your wire is pure copper with wire size 22-24. Do not buy that flat or thin cable.

I really don't know. It likely is some very expensive commerical router. You could of course buy a pc with 2 2.5 or faster nic cards and then run one of the unix router variants. I don't know how much cpu your would need but there are likely sites that discuss that. Most times you are using these type of pc as firewalls or vpn boxes which put much more load on them than a simple NAT box. My guess is a couple hundred dollar machine will do since you do not need video cards or even fancy SSD.

Like I said someone asked this exact question and I recommended that they look at microtik but after I went and tried to find something and all I found were switches and all kinds of extremely expensive stuff that were for things like outdoor use.

Again hopefully someone else who watches this thread will know of a device. I kinda want to know also.

I get this far and I have another option. I can get 5gbit if I want to spend the money and since my connection is fiber I have to use the ISP router but it has a 5gbit and a number of 1gbit.

Maybe replace the modem with a modem router that has a 2.5g port. A quick search shows arris g36 should do the job.....likely expensive since it supports wifi6 also

From the spec page, it's not clear, but it appears that the router only has 1 multigig port, which you can use for WAN. That means you only have gigabit ports available to connect to the computer. You can use multiple computers and run 2 speed tests, then make sure they add up to your 1200mbps plan, or run a speedtest on your pc and phone at the same time.
I built my own router using spare computer parts with an x86 processor. It'll handle multigigabit internet just fine and you can install whatever multi-gig ethernet cards you want for WAN and LAN. Then use it to feed a multigigabit network switch.

This is a list of consumer grade routers with multiple multi-gig ports, so you can have multigig WAN and LAN: https://dongknows.com/multi-gigabit...-routers-with-two-or-more-multi-gigabit-ports

Asus AX6000 has dual 2.5gbe ports for around the same price, hopefully you can return that netgear router: https://www.amazon.com/ASUS-Rapture-Gaming-Router-GT-AX6000/dp/B09L8PCTPT

Do they make a single port wan\internet ethernet port that would bypass my having to plug into the wan internet port on the router that only supports 1 gig. The difference is that if and when I'm able to use a single wan internet multi gig port via USB regular type not c Then I would get over gigabit speeds when I run speedtest.net. I would get 1,447.68

thank you so much!!

The other thread you had on this topic had a list of routers that have multiple multigigbit ports.

Right but I'm now looking for a single Multi gig wan Internet port that's usb and would allow me to plug into it and bypass the Routers 1 gig Wan internet port. I already spent a lot of money on this router. And I don't want to replace the whole router if I don't have to just for 1 wan Internet port capable of Multi gig speeds. If there is a single that is a lot cheaper.

I have not see USB ports used for network traffic in many years. Some you find allow you to connect a USB based mobile broadband modem but that is very slow compared to what you are talking about.

What I don't understand is even if you find a router that has a USB port how do you intend to first connect it to arris modem that only uses ethernet. In addition how do you see you would use your current router that also only supports ethernet connections.
The only device that could connect via USB would be your PC. USB is very cpu intensive compared to ethernet. You are likely going to be limited by the CPU speed in the router. The ethernet ports are function done almost exclusively in hardware and the NAT function also is done in hardware on most routers. Not sure about these really fast routers but if the traffic must pass through the cpu chip you many times get your rates capped at under 350mbps even on devices with the highest clock rate cpu.

From what I can tell you are going to spend at least $300 to get a solution. It seems the cheapest way would be to replace everything including the modem with the arris g36 router. You then no longer need a wan port because it is connected internally to the modem with what appears to be a 5gbit port but i am not sure on that, it will easily give you 1.2gbit.

Well I have an arris s33 Cable modem and it has a 2.5 port that I'm connected too By an thernet cable cat 7 and if I connect another eithernet cable going straight to the back of my computer to my 10 gig ethernet card When I then go and run speedtest.net I get speeds of 1,447.28 and I get a link speed in my network and sharing for my ethernet card of 5 gigs. The reason I get this speed is because I'm going from all Multi gigabit ports just 2 one from the back of my modem to the back of my 10 gig ethernet card on the back of my computer. Bypassing the router completley and my tp-link 5 port 2.5 gig switch. So

Bypassing the router completley and my tp-link 5 port 2.5 gig switch. So I get those speeds of 1,447.68 as reported by speedtest.net. But if I connect to the router and go through the wan Internet port which is the only port that I have to connect to which is 1 gig the rest are multi prt then I get speeds back down to 947.68 Around that. So I was just looking for a single Multi gig wan internet port and I'm assuming that it would have a usb at the end and then I could plug it into my computer and then Plugg an ethernet cable into that Bypassing having to plug into the wan internet port on the back of my router that is only 1 gig. And then I would get my multi gig From the multi gig wan Internet usb port plugged into a usb port and then I would get the Multi gig speeds and it would be a lot cheaper than having to by a whole other router and I would see the Multi gig speeds as reported by speedtest. But I guess no such device exists and I would have to buy yet another router. I thought theswitch I just bought was going to do the trick but I realize now that it doesn't have a multi gig wan port on it. The only thing I can do is have a cable going from a 2.5 port on the switch to the back of my computer to the 10 gig tp- link card and I will get a link speed from my ethernet card of 2.5.

The main issue I see using USB to do this is how much CPU power it will take. Almost all routers use a hardware NAT accelerator to allow traffic to bypass the cpu.

On your current router there might be a option to disable this hardware acceleration and see how bad it would be. Most time if you were to put in a simple firewall filter like block traffic to some random ip you do not actually use this will force all traffic through the cpu. From routers I have played with that have very fast cpu it drops the speed to about 300mbps.

This is also why you can't use a lot of the fancy features that a router says it has. If the cpu chip must process the data it can not use the hardware assist.

The only other way I can see this done with a single 2.5g or higher port is to run what is called router on a stick. Both the WAN and LAN then share the same port. To do this trick the router must support VLANS and you would then need a switch that supported vlans to connect other devices.
You would at the very minimum need a new switch but they are fairly cheap. It is not likely your router supports this and from what I see third party firmware like openwrt is only just starting to be done. What I don't know is even if you do this trick can it use the NAT hardware accelerator. The problem with third party firmware in general is it does not have the support for the nat acceleration because of software license issues.
