On a unmodified wii with a legit copy of Monster Hunter Tri, when online the game would randomly freeze and the speakers would emit a loud "HRRRRRRRRRR" noise. I found out this was caused by an IP confliction (a new computer/device getting on the network and kicking the wii offline). I can confirm this after looking at into the router and replicating the "HRRRR" noise a second time by forcing a confliction (you know, for the lulz). I am not saying this is the only reason people are getting this type of freeze (probably not for people using USB Loader GX). I'm just putting this out there because it's possible it is someone else's problem too. Solutions are to filter the mac address on the router, so the wii (and other computers) never conflict. I will atleast make the wii statically set. Other solution is to get a router that actually does its job (IP conflictions should not happen... I hate this netgear I have).
