With my router between my modem and my PC:

With my modem connected directly to my PC:
![\"622648146[1]\"](\"http://www.sonictempest.net/wp-content/uploads/2009/11/62264814611.png\" "\\"622648146[1]\\"")
Thee words: What the fuck?
EDIT: Apparently something in the router settings was messed up – I reset it to factory settings and suddenly I can watch 720p streams without buffering. o_o
