Multiple DDoS Attacks + Internet Freezing Every 30 Seconds

[ningattes]

I am getting anywhere from 3-10 ddos attacks per day, multiple of them coming from the same IP, and it's happening every day, and it's really annoying. I've tried installing some free VPNs and DDoS protection programs, none of which are helping. These 3-15 attacks I have to deal with each day are stored in my Netgear router logs, and here's one I had a few days ago.

Not only that, but whenever I'm playing CSGO or Minecraft, my internet freezes (including voices stopping in teamspeak, skype, mumble, etc), and it happens every 20-90 seconds for about 2-6 seconds, and sometimes there's a tiny 1-2 second freeze following that.
I'm not sure how many of you play competitive Minecraft and CSGO, but if you do, you know how much a ping spike or huge internet freeze can cost you your game sometimes, and this has really been pissing me off.

More info:
My internet is Time Warner Cable (live in the middle of nowhere), my router is a Netgear WNDR4500v2 which I got before all this happened. Originally when I got the router, I had no lagspikes, or at least none that was like this. Then I got another modem, and then there was some lag every few minutes or so for like 2 seconds which wasn't that big of a deal, I really only noticed it in CSGO, but a week or so ago, I got a new modem, and it was fine for a few days, until it was like 4 or so days ago I started getting the issue I described above.

Any help would be nice, I've tried factory restoring my computer, and I've made sure no games or software is updating in the background, but no luck.If needed, I can give more info on the issue, and my software/internet, etc.

You can't be attacked unless someone knows your IP address. Changing your router's external MAC address and restarting your modem typically gives you a new IP. Just make sure you're not using any P2P programs that give away your IP address to those connected, like Skype.

I am using skype and I really can't go without it, but I've removed tons of contacts and basically cleared my skype a lot, so that might've helped. I also use Teamspeak, but usually not as much as Skype, and rarely Mumble.
I'll fiddle around with the MAC address tomorrow, and I'll update you then.
Thanks

No luck. Still the same issue, and it doesn't seem like it has gotten any better or worse.

You are going to have to give up skype if someone is really attacking you. All they need is your skype id and it does not matter who you block. You pretty much would have to have a skype that you told nobody.

You can change you IP over and over and skype will send it out as soon as it comes up. All they have to do is look up your skype id and see what ip is associated to it.

Even VPN does not work well. Skype tends to come up before the vpn so it will expose your real ip for a short time until the vpn becomes stable.

I didn't mean to select this as the best solution.
I'm not going to give up skype, and many people have skype, but they don't get DDoSed all the time, even when they have many more contacts than I do, and they also don't get ping spikes every 30 seconds.
This seems to be a problem only I am getting, or at least I can't find anyone else with this issue online. I'm still dealing with these lag spikes.

It may not be a actual DoS attack then. You have not looked far if you have not found all the discussion of skype. Streamers get DoS all the time and most no longer use skype.

It has nothing at all to do with your contacts. All someone needs to know is your skype name, it doesn't matter how they get it you could write it on paper and once they have it they can DoS your.

It could be as simple as you are now getting errors on your line coming to your house and you just happened to see those messages. Unless they happen every time you have a problem it is not a DoS attack.

Oops again...

Anyways, I know that every ping spike I get isn't a DDoS attack unless someone's sending me packets every 30 seconds every hour of every day which would be pretty ridiculous. I'm just really confused why it's happening more on minecraft than on csgo or other games, and why/how it's even happening in the first place.
