You  must have just rebooted it. Try it after its ran for a while or after it does a reboot cycle

    Router was working mostly fine today until a few minutes ago. I pulled this from Event logs just now

      Seems like your logs are clearing out in the reboot. that makes it more of a challenge because now we're just guessing. 

      1 thing you can try is if you have a seperate power supply sitting around that has the same voltage and polarity and AT LEAST the same amperage rating (it can have more but not less), try that. Maybe the power supply is going out and failing under load/heat.
