NETGEAR Nighthawk X6S (R8000p) AC4000 having issues getting full gigabite download speed.

So I recently upgraded to Spectrum's 1 gig along with their Sercomm ES2251 from their 400mb package & for some reason when I do a speed test it will cap out to 947mbs at it's highest. I say at it's highest because it's fluctuates downwards.

Anyways, I have plugged my pc directly into the modem & speed tested it to come to 1056 so I know for sure there's something going on with the router. I have tried factory default several times, I've tried

 

rolling back as far as 1.4.1.42 with no difference.

 Turned off traffic meter

No Armor

QoS is off

No Circle

Uninstalled the app from my phone

Disabled WIFI

Unplugged every device BUT my PC

Made sure the ethernet cables were at least Cat5e

Changed WIFI channels

Tried turning IPv6 on

 

I have legitimately tried everything I could think of. This router turned 3 years old on August 19th so it's not too old. So, I don't know.

P.S., not paying $50 for technical support. 

 

 

 

 

 

  • Maybe a choice however the router IS only designed up to a certain point and capabilities of the router at the time and what the internal components were designed for. Also there Is bandwidth overhead as well that is at play too. All this is nature of the beast and would be the limiting capabilities of ANY Router of the age and support. Been like this for a while now. 800-900Mbps is nothing to shake a stick at as the router is working at it's max capabilities. If you want to see speeds on the WAN to LAN side over 1000Mbps, you'll need a router that supports 2.5Gb connection rated ports on the WAN and LAN side.

    Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.

     

    Has a power off for 1 minute then back ON with the ISP modem and router been performed since last update?

     

    You'll not see much over 950Mpbs on a ethernet connection thru the router. Since the WAN and LAN ports on the router are all 1000Mpbs,1000Mpbs caps out at around the range your seeing, depending on PC CPU, Ethernet adapter and ethernet lan cable.

      I've powered it off many times for 1 minute. Had to when to connecting to modem from pc due the network not recognizing it. 

      CPU is pretty up to snuff. Ryzen 3800x with an Asus ROG x570 Crosshair VIII Formula capable of 5 Gbps LAN.

      As for the range with the router, well, was hoping it would at least cap out at 1000 mbps but I can see if that 800-900 is it's range then well I made a poor product choice.
