Very weird situation
We have a couple cameras setup in our house for security and they're connected with an ethernet cable to the router so they can be accessed through the internet from the mobile app. After upgrading our internet speed the ISP provided a new 1gbps router (much better than the older one) but for some reason when I run any program/online game that requires internet on any pc/mobile it acts as if it's prevented by a firewall or that the internet is very slow to the point that it disconnects and connects endlessly even though the internet seems fine from the speed test (over 300mbps). As soon as I disconnect the DVR from the network everything goes back to normal.
Examples of programs/games:
PC
League of legends: The launcher opens and lets me login smoothly but as soon as I am in and press play it gives me that disconnect error as if I don't have internet even though I do (I can surf the web, watch netflix, etc..).
Steam:
Takes minutes to let me login and all the online games they either launch but very laggy with multiple disconnects and reconnects or they don't launch at all. Surprisingly, updating the games themselves from steam is fine.
TeamViewer: I can login into my account without any issues and once I choose a pc to connect to It lets me connect for around a minute then freezes forever.
Mobile:
TFT: Can't login, it acts as if I don't even have internet.
TeamViewer Mobile: After connecting to a remote pc for around a couple minutes it freezes and says that I don't have internet.
All of these issues are literally solved as soon as I unplug the DVR's ethernet cable from the router.
I tried checking if really it was a firewall issue but everything checks out. I also reset the DVR's software but it did nothing.
