Installing and Using OpenWrt
1

I am using Netgear R6220 with openwrt 18.06.1. It reboot at midnight even I reset the device. I have installed adblock and turn on hardware offload after resetting the device. Hope anyone can help me figure out the problem.

  • Please use </> in the menu to post code in the future
  • Does Adblock update run at midnight?
  • What does this mean?
  • Did you do this in attempt to fix the problem?

I run the adblock update on 4am, I think adblock update is not the cause.
I reset to defaults on luci because the problem happen frequently (2-3 times per week).
I turn on hardware offload, I am not sure if it is the cause of problem. The problem happens even I turn it off.

Well, mac80211 on the error dump means wifi driver, or wifi config.

Try turning wifi off for night.
