"DNS Server Not Responding" and "Network Not Responding"
Like the title says, I keep getting those errors, be it in browsers (Chrome and Microsoft Edge) or video games. I don't usually get an error when streaming shows/movies on my TV, but the same 'not-loading' issue happens across all my devices. I've had this problem on other households networks (also Xfinity) as well, on multiple devices. At first I thought it was just my computer, but turns out it's everything I connect to my network, both Wi-Fi and ethernet alike.
Aside from having a tech coming out today to check things, I've tried everything I can think of. I never actually lose connection because I can still play my online games, but at some point while playing, I get kicked from squads that I was hosting. Two game examples off the top of my head are World of Warcraft (which disconnects me entirely from the servers and forces me to log back in, launcher included) and Warframe (Network Not Responding error, followed by disconnection from my teammates and forced to finish soloing). I know I'm not losing internet connection because games like Warframe would outright log me out if I were, it wouldn't let me finish playing a mission. Also, me and my fiancé both are still in group together in-game, it just won't let us 'keep' connected to other players for some reason.
This all happens easily every half hour or less, for 2-3 minutes at a time. I've contacted tech support over the phone but they always just give me the same scripted routine of "Nothing's wrong on our end," "I've sent signals to boost your connection/performance," (which they'll never explain when I ask what that entails), and "We can schedule a tech visit if you'd like." Beyond that, I've also checked all connection points and made sure they were all tightened fully and checked wires to make sure animals hadn't chewed them up.
I did find online someone had a lot of "noise" in their home though, which apparently their tech guy had to remove a lot of old wiring from the house and they were forced to move their router to the opposite side of the house. I don't know how much of an issue that can cause, but I do know I have an overly extreme amount of old wiring ran underneath my house. But at my parent's house, they don't have all that wiring laying around and we have the same issue there as we do in our own house.
I've honestly tried a lot of different things in my modem's gateway and on the various devices themselves. Simply put, I don't seem to ever lose connection at all, but every half hour or so I get those errors and can't host games/load browsers/stream anything. I'm at a complete loss at this point.
