I can't seem to get connected. I have a Linksys WRT54G ver 6 router in mixed mode, no WEP, and have various PCs, Xbox 360, and other devices connected successfully. The Wii can see the broadcast network SSID (when I broadcast it, but I usually don't), so it can get that far, to the router. But when I set up all the networking settings, it immediately (in a fraction of a second) fails the connection test with error code 50100. I have tried channels 1 and 11 (rather than 6), to no effect. I am entering all the settings manually, not using DHCP or broadcast SSID (normally, other than the test mentioned above). I have checked and triple checked these entries and all seems correct. The Wii sits near the Xbox 360, which is successfully connected (with all the same settings except for IP) with good signal. Any ideas? Any help or suggestions much appreciated!
