Router Security Issue

On my router log file, I noticed many DoS attacks, both ACK scans and Smurf. The router is a Netgrear Genie R6300v2. Any advice on what to do. I also need to get a new router, as this one does not have a built in firewall. I would like a good router with wifi which allows for a VPN configuration as well - advise?
Thank you

A DOS attack is only mitigated by usually throwing more bandwidth at it. it the attack is not getting from the router to your internal network then things are fine..  a million dollar router and firewall will do the same thing, discard the packets

YZTC, your router has a firewall (at least the documentation says so @ http://www.downloads.netgear.com/files/GDC/datasheet/en/R6300v2.pdf ). I guess you have wrong expectations as to what it can do. It cannot prevent you from attacks, it can only prevent that those attacks succeed - but that is normal.

I looked up the IP address of the attack, and they are coming from Honeywell. I have several Wi-Fi thermostats.

Are they really an attack or the IOT thermostat simply calling home so you can manage all the thermostats from a single management page.

Not sure. Would these happen even if I am not accessing the thermostats?

yes they will periodically phone home i.e. every time the temperature changes or a scheduled change occurs.   You have to monitor the network traffic i.e. using a tap and wireshark.
