Reduced Bandwidth RBR850

my internet speed has been cut in 1/4 and i don't know why. The speed test on the router used to read 820mbps and now only 93mpbs. I had my ISP come out and test and they get are getting 820+ from the port in the wall but the port on the router is 93MBPS.

    An Ethernet speed of "just under" 100Mbps is a highly suspicious number.  (Even 1Mb over 100 would be an entirely different situation.

     

    My first step would be to look at the Orbi web interface, Advanced Tab home page, and click the Blue Box Show Statistics.  It should look similar to this:

    If the WAN port reports 100M/Full (rather than 1000M/Full) then the modem and the Orbi have determined that the highest speed they both support is 100Mbps. 

    https://en.wikipedia.org/wiki/Autonegotiation This feature in built into the Ethernet hardware on the modem and router.  The user has no control over the process.

    There is overhead even in Ethernet, so the maximum speed through a 100Mbps connection is "under 100Mbps".

     

    But wait, "nothing has changed!!!"  If the speed has dropped from 800+ to under 100, then something must have changed.  Perhaps someone jerked on the cable and pulled one of the pins loose inside the RJ45 jack?

     

    If the WAN port reports 100M/Full, the obvious next step is to examine the RJ-45 jacks on the modem and router and then swap in a different Ethernet cable.

     

    If the WAN port reports 1000M/Full,  oh dear!

  • 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?
    Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended. 

    Who is the ISP? 

     

    How many RBS are deployed? 
    What is the size of your home? Sq Ft?

     

    Does this happen with the RBS turned OFF? 
    Does this happen with both wireless and wired devices? Different Wired PC to compare
    What channel configurations are currently set on the router? 

     

    Try disabling the following and see:
    Armor, IPv6, Smart Parental Controls or Circle, Traffic Meter.

     

    Be sure to disable any MAC Address randomizers on phones and pads while at home:

    Has a power off for 1 minute then back ON with the ISP modem and router and satellites been performed since last update?
    Be sure to restart your network in this sequence:
    Turn off and unplug modem.
    Turn off router and computers.
    Plug in and turn on modem. Wait 2 minutes for it to connect.
    Turn on the router and wait 2 minutes for it to connect.
    Turn on computers and rest of network.


    Has a factory reset and setup from scratch been performed since last FW update?

      Firmware Version: V7.2.6.31

      Model: RBR850

      2 RBS deployed: Router, 1 Satellite

      2300 SQft home

      Modem is provided by a local ISP here called Comporium. Which a technician came out today and verified its in working order.

      Both Modem and Router was rebooted earlier before ISP came out.

      When plugged in directly to Internet Port in wall getting full 800+ Mbps speed

      Wired connection to Router is getting 93 Mbps

      Speed test in Orbi APP getting 93 Mbps, along with speed test from deviceArmor, IPv6, Smart Parental Controls or Circle, Traffic Meter - was never enabled

      Have not Factory reset device as of yet was hoping for resolution before resorting to ressetting.

        What is the distance between the router 📡 and satellite(s)🛰️? 30 feet or more is recommended in between RBR 📡 and RBS 🛰️ to begin with depending upon building materials when wired or wirelessly connected.
        https://kb.netgear.com/31029/Where-should-I-place-my-Orbi-satellite ‌‌🛰

         

        For that size of home, the RBR and just one RBS would be needed. Having two may cause some problems. 

         

        Is there a brand name and model# of the ISP modem? 

         

        What does the speed look like on the RBRs web page under Advanced Tab/Show Stats/WAN port. 1000mbps or 2500Mbps should be seen here.

        Glad it is on the ISP modem. Hopefully they can get you something that connects at 1000Mbps. 


        Enjoy.
