DoS Attack disable my wifi

recenly my wifi keep discontecting. i have to reboot to get it back  

my router is the latest version . 

i did factory reset which didn't help . i downgraded it to the previous version (see the picture) it didn't help it keep disabling my all my wifi. the 2.4 and 5ghz LED light on router still blinking though  

 

i checked my log . not sure if this related to DoS Attack . it looks that this happen every time after a DoS Attack. 

i will try (but i am not happy ) to disable  the Disable Port Scan and DoS Protection to see if this will help

if anybody have  some solution please share. hope netgear can fix this in the future

      Disable Port Scan and DoS Protection didn't help 

       

      i did change the default MAC address of the router this actually helps. I am still having those “DoS Attack: ACK Scan” i have not noted any disconnection however based on a log file it happened overnight a starting of  Firmware  which may indicate a router reset.   instead of happening every hour,  now it is happening every two days which is good somehow .  netgear has to work in fixing this issues in its next firmware upgrade

  • as follow up! 

    It looks like nothing works . downgrading, or changing MAC address didn’t work. I ordered another router. Eventually  this attack stopped and the router was working well for the past week.
