I have been having problems lately using my Wii and it's wireless internet connections through my Buffalo router. I have been able to "successfully" connect, however, when I go to download either the latest firmware, Nintendo channels or games that are available. I receive error messages and can not download. I am able to play games online, but just not download anything. I contacted Nintendo and ran through a series of different settings and was still unable. I took my Wii to a friends house and connected it to their wireless router with no problems. I was able to download and install the latest firmware. When I brought it back home and reconnected it; I received the same error messages. I do not believe it is a Nintendo issue, but an issue with my network. I am using Verizon DSL modem and connecting to internet using Buffalo router and PPPOE. Any help would be appreciated.
