Hi everyone, my family have an outdated modem from 2019 but have never encountered any DoS attacks or issues until today. Someone tried to breach the firewall using a teardrop attack, I’m not sure if the firewall was able to stop it because the connection has been horrible today, extremely slow and earlier we couldn’t even connect to the internet. How can I prevent this from happening again and is there a way to know if the teardrop attack went through, obviously the packets sent would overwhelm the modem but I can still access the internet. I changed the passwords and ssids of my WLANS, I have 2, 2.4 and 5 GHz. Would that be enough? I’m also not sure what the other errors are and if they’re related to the attack, they happened a few hours after the attack
