Ok. Port 67, along with port 68, is used for DHCP. It's a little strange for the router to be complaining about DHCP unless somehow it's detecting a large burst of DHCP Requests in a short period of time.
According to your logs, the timestamps between "attacks" are several minutes to several hours apart, so it doesn't seem to be happening all that frequently and is probably not a real DoS attack. Perhaps you have an old device on your network that doesn't have a good DHCP Client implementation. If you are not seeing any performance or network issues, then I wouldn't worry about it.
Do you, by any chance, have Access Control enabled? Someone else on this forum started seeing this DoS attacks logged after enabling Access Control. We guessed that there is a bug with the DoS attack detection algorithm that is exposed whenever Access Control is enabled.
Access Control is easily bypassed, so it's nearly useless. It's no substitute for a good, strong Wi-Fi password. I recommend that you disable it.
No I do not have access control on.

Okay. Thank you so much for replying. That really helped me!
