R8500 Constant WAN Internet disconnects/connects!

    My wireless is rock solid, never disconnects. The WAN is another problem, see below from log:

   I am also noticing numerous Time Syncs. On firmware R8500-V1.0.2.28_1.0.42.

 

QOS ON

Band Steering ON

14 static ip's

 

Anyone have any insight?

  • Same problem here (I started the thread) WAN disconnects.

    Cable company came out and tested and replaced the Modem.

    2 Hours later I had a WAN disconnect. RMA # 2 will be here today.

     

    I never had this problem with the R7000!

  • Having a similar issue, although I lose both Wired and Wireless access. Sometimes the router successfully reconnects while in other instances, I have to reboot. I recently applied firmware V1.0.2.28_1.0.42 with hopes some of these issues would encounter more elapsed time between disconnects - no success. I have confirmed my cable modem is not the issue by working with my ISP during the disconnects. I am running QOS and UPnP.

      Can you guys try to lower down your MTUs?

      See this link.

        OK just set mine from 1500 to 1472. Will report back.

  • Just upgraded to the R8500 from the R7000.

     

    Seemed to be working fine last night, during setup, it prompted me to update the firmware (which I did) to V1.0.2.26_1.0.41

     

    All day today, I've been having constant cutouts of internet connectivity.  I think it may be an issue with my cable modem, as it looks like it is in the middle of rebooting everytime I lose connectivity but, is it in anyway possible that the router is causing this?  Perhaps some kind of feedback to the modem?

      Bypass the router by directly connecting your pc to the modem and see if you'll experience drop outs.

      After firmware update, I suggest that you factory reset the unit then reconfigure.

        Did that when I was on call with cable company.  Seemed like the modem was still power cycling.

         

        I suspect it's either the modem or signal issues with the cable company because, even when the internet connection drops, I still have WiFi connection to the router.
