Okay, this is bugging me. I've been getting random lag spikes since a few days ago. It started up randomly for no reason at all. I haven't touched anything, it just happened, and makes little sense to me. I tried quite a few things to make the internet work up again. All computers in the house are getting the lag spike problem regardless of what on the internet they do. Whether it's browsing sites, watching videos, or playing online games, there's random lag spikes every few seconds. I'm confused as to what made this happen in the first place.

Some things I have tried are:
Repairing the connection
Flushing the DNS through CMD
Leaving the modem and router unplugged for a whole night and plugging it back in, in the morning
uninstalling the modem and router and having windows relocate it after restarting

Anything else, I'm open to. I ran a few tracerts to two sites I commonly use and these were the results:
