DoS attack (alien.top)

Hi everyone, my family have an outdated modem from 2019 but have never encountered any DoS attacks or issues until today.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

Shutdown your router for 30 minutes. It will probably get assigned a new IP after reconnecting to the internet.

I'll try that out, thank you

You can also try calling your IP and having them reset your IP.

Just pointing out you answered your own quesiton. If you know you're on an old / unpatched / vulnerable router I would suggest getting one that is patched. There will always be things crawling the internet for exploits. Some just look but others may attempt stuff on home users.

Just my $0.02

Yes I'll definitely get a new router, this attack just took me by surprise but as you said, there are always risks

A teardrop attack likely won't "breach" the firewall, it's just a denial of derive meant to kick your network offline. Turn your modem off for an hour, check it works once it's back on and otherwise call your ISP to get a new IP.

Makes sense, there's no risk information leaking or anything, it's just meant to overwhelm the modem. I'll try that and hope it works
