I have a question. For 2 days my internet is always very slow after 9 a.m. Every few minutes and I always have a lot of lags in my game (Fortnite) that goes away after a few seconds but it still annoys my family even after 9 o'clock. Do you have any idea what the reason could be. Ps: And yes I have connected a Lan cable to my PC. Looking forward to your advice!
Maybe it's because of the modem, try some speed tests. I can recommend Ookla and wieistmeinip.de. But it could also be that it is up to the provider, since the servers are currently very busy. And after 9 a.m. Almost everyone is at home and this places a heavy load on the network. Maybe you should wait until everything is back to normal. You could also call a technician to see if everything is correct.
