Since all the working from home started - I've noticed sporadic interruptions while using Video conferencing and while gaming. I will get ping spikes for about 3-5 mins and then it's pretty much back to normal. I researched a bit and found that some of this is just scans that happen normally, but some of the ports I'm seeing are not what people reference as "common ports", 443 and 80 being the most common. I attached the logs in a spreadsheet. Wondering if someone could let me know if I should be concerned or what I should do about it? I really don't want to deal with the interruptions in service and I don't know what else could be causing the interruptions. Any help would be greatly appreciated!
as for the IPs they are all varying and I'm not positive how to determine if they're from an external address - of the 256 lines I pulled from the log, 125 of them are DoS related. An actual attack doesn't make sense to me, but if not this, what would be causing my newly minted spikes and disconnects while gaming?

You can use a whois lookup service online to see what those IP addresses are coming from.
You should have your ISP change the IP address that is coming in from the modem as well to see if anything changes.
Some IPs maybe from services to devcies on your network. You may want to turn OFF all devices accept for 1 wired PC to see if the entries disapate any.
Have the ISP check the signal and line quality UP to the modem. Be sure there are not coax cable line splitters in the between the modem and ISP service box. Be sure your using good quality RG6 coax cable up to the modem.
I have been collecting the logs from two Orbi's (one for over a year, one for 8 months). These logs record these "DoS Attacks" every day, and this is entirely normal. Orbi contains a firewall for a purpose. It rejects attempts to connect and has an option to record "interesting things" in the Orbi log. People have posted comments indicating that Orbi is to "liberal" at classifying random connection attempts as "attacks".
The user can "Disable Port Scan and DoS Protection" on the Orbi web interface, Setup, WAN Setup page. I believe this will stop the system from spending processing time recording and classifying things and writing them to the log. I am not confident that there will be a noticable improvement in performance.
Orbi's have a "public IP address", just as we have "public" street addresses and phone numbers. It is almost trivial to create a program which will "scan" IP addresses looking for systems that respond. This has been happening since the internet was created. It's like RoboCalls that just dial every possible phone number hoping that some of them will answer. I can set my phone to ignore certain calls and not ring, but that doesn't make the calls go away.
Since the service problems are serious, I would certainly try checking that box first.
Did you test pings with a wired PC connected directly connected to the modem? Not with the RBR connected.
Have the ISP check the signal and line quality UP to the modem. Be sure there are not coax cable line splitters in the between the modem and ISP service box. Be sure your using good quality RG6 coax cable up to the modem.
Unfortunately, I don't have a way to connect a PC to the modem directly, I use a Surface book pro, which doesn't have an ethernet port. Does it look like the ISP is causing the issue?
I had XFINITY refresh the gateway signal - I will try to get them to look at this more in depth. No coax splitters - direct from the wall into the modem. Everything was working fine until last week when this started happening. I've never had these issues before.
Does your Surface have a USB port? If so, you might check into getting a USB to LAN adapter. Then you can connect it to the ISP Modem and test again. Need to rule out the RBR or modem.
If this was not a problem up to that point, then possible something on the ISP side.
I connected my dock to the Orbi satellite and pinged 8.8.8.8, got flawless results - removed that and right back to ping spikes - could that be an indicator of issues? still would not explain the ping spikes i'm seeing on console because it's connected to the satellite as well. I also pinged my WAN IP and got similar results.
