My grandson just got a Wii and I shipped him Mario Kart. When we play online in the friends mode he continually gets disconnected. He can go play online in regional or worldwide and doesn't have any problems. They updated their Wii and have the latest firmware. They are using Verizon FIOS for Internet and have the WIFI modem from them, but I'm not sure of a model number if that may make a difference. Any help with settings, etc., would be greatly appreciated. Thanks.
