WiFi really slow after nvidia gamestream

[abster]

i was using nvidia gamestream with the app, moonlight but after a while my internet connection became really poor, sometimes it wouldn't work at all and i had to turn the router off and on again, but it still is really slow

check your connections with curports

if that doesnt show anything suspisious the try wireshark. its a forensic network analyzer.
set it to your ethernet port you want to monitor. hit start.

if you see a lot of arp requests (say 100 in the first second) then get onto your isp as you may be suffering a ddos attack or they have badly configured 1 of there nodes serverside.
