Additionally, a fresh router isn't going to help. The truth is, your ISP permitted that data to reach you.
A router can assist to some extent, but it will reach its limits when the connection becomes overwhelmed. Creating a custom x86 router using tools like pfSense could provide robust performance against various challenges.
It varies a lot, but many tiny links can quickly overwhelm most home routers before your connection is fully used up. Being ready helps a lot. If it gets this bad, the link will be saturated, so the ISP should be blocking it—I’d expect that. Luckily I haven’t faced this problem before.
Yeah, but most internet connections are shared among many users. This means other customers might experience issues at the same time. In my ISP's network, there are roughly 130 people connected to each node. That’s a significant number who could call or complain. Also, it would require a large botnet; based on what I read, my ISP handles about 10 Gbps per node. If one node goes down, Comcast would likely notice.
A Cisco ASA with strong capabilities can serve as an excellent firewall, though it comes with a challenging learning curve. As mentioned before, having a firewall on your connection won’t fully resolve the problem because its impact extends beyond your local network once the traffic leaves your ISP. Switching your IP address is likely the most effective temporary fix until you face another targeted attack. Consider updating your IP and then explore using a VPN for added security.
