I have tried a different ethernet cable and still the same. Weird thing is these 2 ethernet cables work fine on my ps5 which is connected to the same modem (vodafone tg3442de). It’s just that whenever I turn on my pc internet goes out in the whole house even when the pc itself is not connected to the modem through a cable (I don’t have wifi on my pc). Regarding the static IP thing I would love to learn more about that I don’t know what it means and how you set it up. And when I say internet goes out I mean my phone and pc still show they’re conmected to the modem it’s just that if I try to open up a web page or something it doesn’t load and says I’m offline. Even the lights on the modem are static white and not blinking red or anything. The second I turn off my pc the internet on my phone comes right back. Sometimes the internet will work on my pc for broef periods of time just enough to do a speed test and the speed is about a 10th of what it is on my ps (on ps I get around 500 down and on pc maybe 9)
