High packet loss, extremely slow speeds, and modem errors

Hello!


As of a few days ago after I have recently purchased an aftermarket modem (Netgear cm600) I have noticed that at during certain times of the day the connection of the internet will just drop incredibly low and will pertain for quite a few hours. I have always had high ping on one game abnormally named League of Legends, where I usually sit at 78-85 ping which instead should be 50-55 ping. That's not really the issue as of right now though, as I end up having about 92 ping on the game whenever this happens but on top of that I end up dealing with 15-25% packet loss which is extremely detrimental and makes the game feel like I'm playing on 300 ping. From just general research on the internet of where people have had similar problems, I've seen that sometimes the registration processes just haven't been fully done which would be generally possible since this router has just been registered recently. There is also the possibility that the line near my house is faulty and needs to be updated, but other than that I guess that would be up to you guys to figure out.

If I could nip this in the butt and to also possibly figure out why I am not getting the ping I should be getting in my video games I would greatly appreciate that. I'd like to for sure figure out why I am dealing with this packet loss though as this is extremely detrimental. I can't surf the internet without pages taking a long time to load and my games feel torturous.

Here are my modem logs ever since I have received it.
