Hello all.

With a gigabit connection, I have an AC1750 and when connecting an ethernet cable (Cat 6) from it to my PC - i reach a max of 400MBPs.

I have done a reset on the router, updated PC drivers, updated Windows.

Via the NBN box - the ethernet cable from that gets me to 950MBPs, therefore the router seems to be the issue.

Everything Leaptel has advised, I have done - got me from 280MBPs to 400 MBPs.

But yes, I am looking to see what else I can do, what could i be missing to get to that ~950MBPs mark on my PC via the router.

Any advice will be much appreciated.

Thanks

    To confirm,

    • What brand of router?
    • How is the PC connected when you get these speeds "280MBPs to 400 MBPs"?

      Thanks for your reply.
      - TP-Link AC1750 - https://www.tp-link.com/au/home-networking/dsl-modem-router/…
      - Both were via the same ethernet connection (router to PC)

        TP-Link Archer D7 is like 10 years old and it isn't capable of Gigabit. Time for a new router.

        • sss9660 on 21/02/2024 - 16:10

          the product page's decription begs to differ. if its time, its time though.

            @sss9660: TP-Link Archer D7 was designed for ADSL2. The CPU isn't fast enough and only has 128MB of RAM.

              @Twix: Well then, I am not going to argue. Thanks for educating me.

              • sss9660 on 21/02/2024 - 16:34

                @sss9660: Any particular recommendations?

                  @sss9660: @sss9660

                  1. How much do you want to spend?
                  2. How big of an area are you trying to cover?
                  3. Is a single router enough or do you need a mesh Wi-Fi setup?
          • Chaddy on 21/02/2024 - 21:32

            @sss9660: Its time get a new router. Or if you want to save money with an older model just about any of the expensive Cisco routers will do the job and should be cheaper second hand.
            Otherwise just grab a brand new one. But maybe not Cisco as they are pricey the newer TP-Link routers should be fine but i'd go Netcomm for something reliable.

        • darkkito on 21/02/2024 - 16:23

          if the ethernet ports are "gigabit" ports, will they be able to reach those speeds then?

          Currently changed to superloop on their 1000/40 plan but struggling to get over 150 mbps. FTTP, router being used is Netgear nighthawk X6 R8000 router connected to nbn box, then cabled up as an access point is Archer C1200 | AC1200. My pc is hard wired to the archer c1200.

          Just thought I would be able to reach higher speeds. Thanks!

          • sss9660 on 21/02/2024 - 16:39

            @darkkito: me too.

            @darkkito: The Gigabit Ethernet in its spec are for LAN speed, it can do Gigabit switching because its all in hardware, but the CPU isn't strong enough to do Gigabit speed while routing (which is in software). The R8000 should be able to get close to that speed with hardware acceleration, which is on by default on Netgear's stock firmware. You could try flashing to FreshTomato and turning on CTF before you go out and buy new hardware

            • ihfree on 21/02/2024 - 16:59

              @[Deactivated]: If the D7 has Net boost, that should enable CTF. Though, this should be enabled by default.

                @ihfree: D7 is a Qualcomm CPU, CTF is a Broadcom-only thing. Qualcomm has their own open sourced software accelerated routing method that was eventually added into DD-WRT, but its not quite as fast as CTF, and if its running at this speed the router/TP-Link's firmware probably predate it

          • Twix on 21/02/2024 - 16:53

            @darkkito: A router with a Gigabit WAN port and Gigabit LAN ports alone is not enough to max out Gigabit speeds. At minimum the CPU should be a dual core or ideally a quad core CPU. At minimum 256MB RAM or ideally 512MB or more RAM.

            TP-Link Archer C1200 only has a single-core 900MHz CPU and 128MB of RAM.

            What ethernet speed do you get when connected to the Netgear?

              @Twix: not sure since I don't have an ethernet cable long enough or a laptop that can test hardwired connection. but 5g next to the router over phone was near 300. Will have to report back after collecting the router the sent which was the amazon eero 6+ and replace the Tp link archer with it as an AP.

              Thank you for the reply, very informative.

          • Chaddy on 21/02/2024 - 21:42

            @darkkito: As others have said the thing you want to pay attention to with Ethernet is the WAN port on the router as that is where the connectivity to the outside world will be coming from.
            Unless you plug a Laptop or PC directly into the NBN connection box.

            • darkkito on 21/02/2024 - 22:53

              @Chaddy: Not what they said but thank you for the contribution.

      • ihfree on 21/02/2024 - 16:16

        It could be just that the router is too old but you could run through a few steps:

        • Check the link speed in Windows
        • Check settings that may affect speed. A quick search suggests "NAT Boost"/QOS/Traffic monitor may have an impact.
        • Try a different cable
        • Check the firmware is up to date

        One or two posts suggest you should be able to get better speeds with a C7, so may be possible.

        • sss9660 on 21/02/2024 - 16:23

          Thank you - i will attempt these points.

          • ozbjunkie on 22/02/2024 - 08:36

            @sss9660: Recently had this issue and it turned out to be the cable between the modem and router

            Easy and cheap fix if so

    Ethernet and internet are two differnet things dude,

    your LAN speeds are differnet than WAN

    even if your internet plan is 1024 Mb (that is gigabit or 1 Gb not 1 GB), then you wont always get the complete 1 Gb interent. it is gonna be shared accross all the devices are home connected to router.

    And also can be reduced by any copper at home (say FTTC, FTTN) then again can be reduced by ISP throttling.

    Also 400 MB/s is quite fast - https://i.imgur.com/jjV9Abf.png 3200 Mbps (but i think you meant 280-400 Mb/s)

    • Brakus on 21/02/2024 - 16:08

      OP said he gets 950MBPs when the PC is connected directly to the NBN box so this throws your argument about copper and ISP throttling out

      • USER DC on 21/02/2024 - 21:50

        ahh sorry didnt understood it properly (never had a FTTP connection) but yeah if he meant connecting PC via same ethernet to NBN internet directly (without any modem) gives him around 950 Mbps internet. and having a third party modem reduced it with same setup,

        then very likely that modem is the culprit for having not good WAN to ethernet LAN speeds.

        • Chaddy on 21/02/2024 - 23:41

          Yeah pretty much what we've all said. That said turns out you can throttle Fibre as well, Deakin had two 1GBPS connections (still do actually ) but the university limits some of the connectivity so students don't try and download the entire internet.

    • sss9660 on 21/02/2024 - 16:09

      Thanks for your response. your assumption was right. apreciate your sharing the knowledge.

    • Chaddy on 21/02/2024 - 21:47

      That is incorrect, you can't get 1GBPS speeds with Copper only 100Mbps the Copper is removed by NBN Co when upgraded to FTTP if its an FTTN or FTTC upgrade.
      You will get slower speeds on Wifi due to interfearance Microwaves etc but an Eithernet connection should be able to get full speed all the time. particularly with CVC no longer being a thing.
      If you can't get 1GBPS all the time then your provider has a shit network no other reason.

  • Brakus on 21/02/2024 - 16:06

    try setting the bandwidth limit to the same connection you have

    • sss9660 on 21/02/2024 - 16:10

      Thanks for replying. Changed this setting in windows as well. was originally auto.

      • Brakus on 21/02/2024 - 16:12

        are you able to set this in the router?

        • sss9660 on 21/02/2024 - 16:40

          sadly no. Ive scoured through the router settings.

  • OldSchoolHarry on 21/02/2024 - 16:22

    How fast is your disk drive on the PC?

    • sss9660 on 21/02/2024 - 16:24

      wow would this have an impact? — the OS drive is an SATA SSD - pretty old but good enough. - drop your knowledge please

      • OldSchoolHarry on 21/02/2024 - 16:32

        SATA SSD should be fine - I got thrown off by your use if MBps vs Mbps.
        If you can get near gigabit speeds by connecting to the NBN modem/router directly, then SSD is not the issue.

        Things you can try:

        Try connecting to Archer D7 via Ethernet and see what speeds you get.
        Make sure you are connected to 5GHz WiFi not 2.4GHz.

        • sss9660 on 21/02/2024 - 16:34

          Thanks. already attempted this, my bad for the wrong unit.

          • OldSchoolHarry on 21/02/2024 - 16:38

            @sss9660: It might just be easier to upgrade your router than troubleshooting. D7 is quite old and lacks modern security features like WPA3.

  • [Deactivated] on 21/02/2024 - 16:47

    That's the max speed of the router given its hardware, its a sub-1ghz CPU modem/router combo from the ADSL2+ days. Some of the higher end router from that era can do Gigabit WAN with cheats (hardware acceleration) like the Netgear R7000 (I had this exact conversation with another poster in another thread recently).

  • apple2016 on 21/02/2024 - 16:55

    I have an AC1750

    The product spec does not specify the throughput of the router.
    This could be a lot lower than the 1gpbs connections.

    For example consider this small business router from Cisco : https://www.meraki-go.com/products/router-firewalls/
    the WAN and LAN ports are gigabit but the throughput is 250mbps.
    For gigabit speeds, you will need a router with fairly good processing power.

  • Wiadro on 21/02/2024 - 20:11

    i get 950mbps on my telstra gen3 on swoop via ethernet cable.
    its easy

  • sss9660 on 21/02/2024 - 20:22

    Thank you everyone. Really appreciate your help.
