Hey can u help me?, I just got a second flood attack, 

In the first only my ether net went down but now everything is down... After last time i found that i could find the source with wireshark. 

And i dont know how to fix this, other than getting the power off for 30 minutes. I dont have a screenshot from the first but it was on count 800 from 1000 or something from same ip.

I think its from someone within my network, i live at a student house with shared internet. Different routers
