I have an orbi rbr 50 as my router connected to an xfinity modem, we have the fastest internet available from them yet I get constant slow downs when downloading from any game service many times. There's usually at least 8-10 devices connected total and we have one orbi satellite for the security cameras and laptop in the front of the house. And being curious as to what is going on I found the router logs on the portal, and have no idea what to make of it. Anyone have a clue what the hell all of these dos atttacks are?

Short answer: someone is trying to force you out of business or at the very least, make your life harder.

Long answer:
In computing, a denial-of-service attack (DoS attack) is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled.

In a distributed denial-of-service attack (DDoS attack), the incoming traffic flooding the victim originates from many different sources. This effectively makes it impossible to stop the attack simply by blocking a single source.

A DoS or DDoS attack is analogous to a group of people crowding the entry door of a shop, making it hard for legitimate customers to enter, thus disrupting trade.

Criminal perpetrators of DoS attacks often target sites or services hosted on high-profile web servers such as banks or credit card payment gateways. Revenge, blackmail and activism can motivate these attacks.

SYN/ACK scans are pretty common. Looks like your router is doing what it's supposed to.

Don't read too much into it, unless you've been pissing-off people on game servers and one of them actually knows your IP addy.
 
In most cases it is your router over reacting. Most scans like this are not actual denial of service attacks. They do not send enough traffic to cause damage. Most people have way too much download bandwidth to be over utilize.

What these more are is a automated program maybe a virus looking for machines that are unprotected. Just having a router protects you from almost everything since the router does not know which of your internal machines to send the traffic to so it just discards it. Your router seems to have some basic firewall that detect unusual traffic. It is being blocked anyway but if it wasn't already I guess the router would block it when it produces these messages.

It all doesn't matter. There is nothing you can do about it. Nothing is getting to your internal machines and even if it was using up all your bandwidth you can do nothing to prevent it.
