XR500 wired/wireless speed degrades after a short amount of time

My speeds degrade over a short period of time.  3 computers are wired and 1 wireless.  Modem>Router>Computers nothing special.  Both the modem and router are brand new 4 months.  Computer direct to modem holds constant speeds over time.  When I reboot the router speeds go back to normal for a short amount of time and the issue happens again.  I have tried doing a factory reset and leaving the config alone. I have tried turning off QoS totaly and nothing there.  Cables are Cat5e and pretty short with the exception of one.   Any suggestions guys , thanks.

  • Do the speeds slowdown for both wired and wireless devices? When it next happens if you go to the setup wizard from settings and just go as far as the speedtest what results do you get? How have you disabled QoS exactly?

      Yes both wired and wireless will slow down.   I will have to check the wizard for the speeds, I run the speedtest from speedtest.net to get my results and will be as low as 5Mbps down and about the same up. I have Gigablast from Cox so I get around 700 - 900 depending on what we have running and what is going on with cox on average.  Running a test from the router I get 459 down and 33 up.  speedtest.net gave me 661 down and 16 up. when I wake up in the morning and do a test it will be down to 5 at the lowest that I have seen.  If I then reboot it it will take me back up to normal speeds. For QoS I went under it and selected never under Anti-Bufferbloat, when I go into it, it will say All QoS features are disabled.

        Does it just happen once a day then from what you gather? When you reboot it in the morning do you see it happen again before the next morning? In Settings go to monitoring > connection status, what does it say for DHCP lease obtained/expires?
