I changed a few things with my netgear MR814v2 router (set channel to 11, open DMZ for the IP of my wii), and then it worked. However, I am still having a weird problem. Almost every 24 hours wii lost its internet connection -- when I powered on wii again, it just got error code 52330, and then I have to go to the MR814v2 router web page to unset and set DMZ again for wii, then it will work again connecting to the internet.
This is troublesome and annoying. Has anyone else had the same issue and know how to solve this problem? Thanks in advance.
