Hey All, I have an extremely slow Nighthawk XR500 (Tested on V2.3.2.130 and V2.3.2.134) that is of course out of warranty. I am paying for 900 mbps which I am getting when wired to my modem. When I go through XR500 with a new cat6 cable (3ft) my speed is just gone by at least HALF, I get around 440mbps. My Wifi (3-4ft eyesight from router) drops to 330mbps on 5Ghz. Am I just out of luck with another dud of a router? I have already tried with Qos disabled and enabled - no differenceFactory restored - no difference Modem is a Motorola Docsis 3.1 Thanks! (Tested on V2.3.2.130 and V2.3.2.134)

I dont but I'll drop by Best Buy after work and get something nice as it kinda seems thats what I will need to do to get my network back up to some what good speeds. I tested with CAT5e and CAT6 is there currently. I also terminated and tested my own CAT6 as well an no large differences. What CAT# LAN cable do you have between the ISP modem and XR router? CAT6 is recommended. @my340i wrote:I first had a Surfboard SB6190 which is when I thought it was the modems problem, I then upgraded to a Motorola MB8611 and still now have the exact same problem which in my eyes has made it crystal clear I have another bad modem from Nighthawk.

Ahh no that was with the xr500 out of the loop. After work today I'll put the xr500 on AP mode and use the new router and run more tests.

Right haha. I test 3 times and average them using https://www.speedtest.net/ , https://fast.com/ (always seems like its really low) and the built in speed test when you google speed test. Yeah I did, I already see where you are going. I'll try out a couple cables.

On it, soon as works over today I'll give it a shot! Also ordered a RK1 router through my work since I get them at cost so I will have a permeant router to test with too.

Any ideas on this?

  Apologies for the delayed response.
  
  A few things:
  
  Have you factory reset since upgrading to the latest firmware?
  
  Did you disable QoS from the three-line menu in Congestion Control?
  
  If you run a Connection Benchmark test, are the speeds showing as being reduced here too?
  
  Do you know if you require PPPoE, VLAN or DHCP identifiers to connect to the internet?

    No problem!
    
    I have
    I did - 3 line menu > QoS > Congestion Control > Never
    They are, they are right in line with my numbers posted above
    They dont, its just a standard cable connection of 900mbps, I just upgraded from 800 thinking it was my modem the whole time causing this issue.
    
    I also had Xfinity out to test the signal I'm receiving and its very good with little to no interference.
