After Fireware Update XR500 Drops Internet When Re-started

I have Spectrum for my internet and use a CM600 modem with a XR500 router. I recently updated the firmware for my XR500 to version 2.3.2.40.  About once a week I turn the modem and router off for a couple of minutes and then power them back up.  I turn the modem back on first and wait until I have all green lights, then I turn on the router.  I've been doing this since I bought this modem last year with no issues.  Now, after updating the router firmware, when I go through my "re-start" procedures I have no internet (orange flashing internet light on router).  Spectrum has double checked everything on their end and all is good and this just started after the firmware update.  I also confirmed the modem firmware is up to date.  Through A LOT of troubleshooting I found a temporary work around, but I need to find a permanent solution.  If I restart the modem first and then the router I get the same result everytime.  But once there, if I leave the router on and re-start just the modem, the orange internet light on the router will change back to white and I have internet again.  Any thoughts?  Thanks.

    Has a factory reset and setup from scratch been performed on the XR router after applying v40? 

    Try reverting back to v32 FW as well...

      Thanks for the reply.  I have not done a factory reset.  I just installed the firmware update. Once I noticed the issue I reached out to Spectrum to see if everything was good on their end.  I made sure the modem firmware was up to date, which it was, and then posted here to see if anyone else experienced anything similar.  I'm not sure I was running v32.  I don't think the firmware had been updated since I bought the router, but I hadn't had ANY problems before now.

        Next time you try v40 or next FW update, do a factory reset after the file is applied and setup from scratch to see if problems continue or not.

  • On the XR500 in Internet Setup is it setup dynamically or static? If you switch it to static and apply does it regain the connection after restarting modem then router?
