Hello,
today my TP-link TL-WR1043ND during night (while I sleep) was somehow hard resetted to default settigs.
The problem is that after reset I had OPEN WiFi AP "dd-wrt" with no password. So anyone may join it and have access to whole my local network while I sleep.

How it was resetted?
My modem often hangs-up, so I use arduino watchdog to reset power off-on with relay module. I found "Power Cycling" in manual: https://www.dd-wrt.com/wiki/index.php/Reset_And_Reboot#Power_Cycling

So if my watchdog going wild and reset modem too often it can be the reason for hard reset?

Also I found some vulnerability here, maybe I was attacked?: https://www.rapid7.com/db/vulnerabilities/http-dd-wrt-remote-command-execution

I have long password and remote control from WAN is disabled, firewall was "on". What settings should I check twice?

My question: Is there some way to change factory reset behavior - so even if RESET happen, modem loads with WiFi AP switched off instead of "on" and open.
