So every day, I routinely get a hard reboot with my OpenWRT router; although I try to find the cause of the problem, I'm not able to and am routinely stuck with trying to figure this out. Has anyone else encountered this issue? I did see other TP Link models facing similar issues.
Then I think I found my cause. It's due to luci-adblock. My RAM is only 64 MB, whilst the recommended adblock list — regardless of size — for any of the adblock list is at least 128 MB.
