Slower wired speeds RBK753

I have recently bought the RBK753 kit to help with my network speeds throughout my house. I have a 500mbs fibre connection and plugged the orbi router into my isp router/modem. I have disabled the isp routers WiFi and have connected both my satellites wireless in the rooms I need them most. I'm having a problem with my satellite speeds on devices I have wired to them. For example my living room satellite I have an xbox series x and a sky q box connected with cat 6 ethernet cables and both have speeds around 160mbs. But in the same room my phone which has WiFi 6 gets speeds of near 400mbs, I was hoping my wired connections would be at least the same speeds coming from the same satellite. When unplugging the ethernet connections the WiFi speeds drop even more to around 60mbs. Is there something I should be doing when connected using ethernet to improve my speeds? I bought this system because all the reviews I watched were getting near on same speeds throughout the house and that doesn't seem to be the case with me.

Thanks
  • Sounds like a configuration issue on the RBR when in AP mode. 

     

    Take the IP address that the RBR in router mode, gets from the modem, seen on the RBR advanced tab under Internet section. The WAN IP address seen there, set up a IP address reservation on the modem for this IP address so it doesn't change. Then put this IP address into the modems DMZ or IP Pass thru. Contact your ISP if you need help on how to do this with your modem/router if you need additoinal help and information.

  • What Firmware version is currently loaded?
    What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? IF your ISP Modem has a built in router, This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

    Couple of options,
    1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
    2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
    3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop

      Thanks for the reply, the firmware version of the orbi is V4.6.5.14 my isp is sky, I'm based in the UK. From what I gather after reading posts online that I have came across when looking for info is the router/modem combo you get from them is that it doesn't have a bridge mode and that turning off all WiFi capability was what I had to do. I'll have a read through those links in the options you have posted and see if I can make sense of it. Again thanks for the reply.

      FURRYe38 I've finally getting around to trying to solve my slower speeds issue, today I've tried turning my orbi router into AP mode but it caused problems with Internet connection. The connection to router itself kept dropping out and purple light kept showing and could get my devices to connect over WiFi either. So I put it back into router mode for now. I'd like to give option 2 a go as that sounded the best option anyway as I'd still be able to use app on phone to manage the orbi system. I'm just unsure what info I need and where to get it. I checked my isp router settings to see if I could find what needed changed and found this(photo attached) if this is what's needed to be changed where do I get the info needed from the orbi?

      Thanks

    There is no logical reason for a wired device to achieve less speed than a WiFi device, as long as the device is capable of higher speed.

    A useful test would be to connect the X-Box and Sky box directly to the router.  If they get the same speed there, they may not be capable of more speed. (It is probably not practical to temporarily relocate either the XBox or the Sky box to connect to the router.)

     

    I actually have 50' and 100' ethernet cables in my "box of network stuff" specifically for this purpose.  I string the cable through the house to connect something to the router (temporarily.  I do this when alone in the house.  Otherwise I would suffer "the slings and arrows of outrageous fortune.")  A $50ft cable is under $15 on Amazon.  100ft cables are under $20.

      I could give this a try as have a long ethernet cable, can't remember what cat it is though but it's at least 7 years old so unsure if it'll support the speeds.

        Any decent ethernet cable will support 1 gigabit. Ethernet cables are rated at 90m distance and perform better when shorter.  A 100ft cable is about 1/3 of 90 meters.

      CrimpOn I Gave plugging my Xbox directly into orbi router a try today and speeds were pretty much full speed that's coming into house so the xbox isn't limited to what it can receive. So just need to sort out the double nat issue to see if that helps.
