MK93S system having slow upload speeds

Hello. I have a 300/300 Mbps network plan with Verizon and an MK93S mesh system, but speed tests on my wireless devices show upload speeds to be much slower than download speeds. Compared to my older mesh router system (which was only dual-band WiFi 5), my wireless devices had speedtests of around 200 Mbps download and upload. After switching to this router system, my wireless devices show a modest improvement in download speeds to around 230 Mbps, but upload speeds have cratered to only around 70-80 Mbps. 

 

In my testing, the router itself’s built-in speed tests show a 300 Mbps download and upload as expected. Hardwired devices also show similar performance of 300 Mbps when connected to the router via ethernet. I understand that wireless devices will not achieve the 300 Mbps speeds, but wireless devices are the only ones experiencing the degraded upload speeds to 70-80 Mbps, which is much worse than my older router. 

 

I am currently running V1.0.2.46_1.0.42 on my main router. Satellites are running V1.0.2.46 as well. 

 

I have tried turning on and off QOS, but neither have fixed the upload speed issue. I currently keep it disabled. Netgear Armor is disabled as well. 

 

Help would be appreciated. Thanks.

  • I’d also like to mentioned I’ve tried rebooting the system many times, but the upload speeds remain the same.

    Which specific wifidevices are being used to measure internet speed?

    These devices are connected to the router (MR90) or to one of the satellites (MS90)?

      Hey, thanks for the quick response. I’ve tested the wireless speeds using my iPhone 16, an M4 iPad Pro, two M1 iPad Airs, and an A14 iPad. I understand that not all of these devices support WiFi 6e—the iPhone 16 and M4 iPad Pro do—but they all display generally the same upload speeds (the devices supporting WiFi 6e are marginally better, around 85-90 Mbps upload give or take). For the sake of testing, they were all connected to the router rather than the satellites.

    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. 

     

    What is the size of your home? Sq Ft? 
    What is the distance between the router 📡 and satellite(s)🛰️? 30 feet or more is recommended in between MR 📡 and MS 🛰️ to begin with depending upon building materials when wired or wirelessly connected. 

     

    Does this happen with the MS turned OFF?

     

    What channel configurations are currently set on the router?  
     Try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.

     

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

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

      Hey, my ONT is the Nokia G-211M-C, and I’m wiring the main node to the modem using the ethernet cable that came in the box with the mesh routers. I’m not sure if the ethernet cable is the issue, especially since other devices hardwired to the router have the full 300/300 Mbps speeds.

       

      My home is around 2500 sqft and 3 floors, with the main node on the second floor and the satellites and the first and third floors, around 30 feet in distance apart.

       

      Yes, the issue persists with the satellites turned off.

       

      My channels are set to 11, 48, and 37 respectively for 2.4Ghz, 5Ghz, and 6Ghz. 

       

      I’ve made sure MAC address randomizers were set off for the devices I’ve been testing.

       

      All of the following “extra” services like Armor, IPv6, and traffic meter have already been turned off.

       

      What’s confusing to me is that the mesh setup I had prior to using this current Nighthawk setup had the nodes placed in the same exact spots and, despite being a much older dual-band 5G model, had a much faster upload speed compared to now. 

       

      Any other troubleshooting information/steps would be appreciated. Thanks.

        What brand and model# are these wifi devices? 

         

        Where did you get FW vV1.0.2.46 from?
