About two days ago my home internet slammed to a halt. I looked on my router's (dd-wrt) bandwidth page and saw a full 5.9mbps incoming on WAN, yet only a few kbps going in and out on LAN and WLAN (This is normal the network is only a few PC's). I swapped routers, I get the same issue. I disconnected all my device, same issue. I let the modem handle the routing and wired it directly to my PC. I get almost no traffic on my NIC, but the modem's activity light is flashing like crazy. I decided it's the modem, so I swap it out. Same issue. Now I'm using the same setup, but setting the modem to bridged ethernet and letting my PC handle the PPPoE connection. This way I can monitor all the packets coming and going using wireshark (above picture). For the past two days I've been getting flooded with TCP packets from what I'm pretty sure is an attacker spoofing a google IP address. Tech support is sending me a new modem, while after 4 hours I finally got someone to put a ticket in to change my static IP. Has anyone ever had any problems like this before?

You probably wrote someone a bad letter and they got mad at you.

Get a better ISP, they shouldn't allow a DoS attack happen against a residential address. If that isn't setting tons of red flags off on their end then their letting the ball drop.
