Hey guys, I'm having some trouble with
error 51420 on my vWii when trying to connect through a LAN adapter for online games launched in USB Loader GX(r1281). Apparently, this is normally an error you get when using an incompatible LAN adapter with your console, but the thing is my LAN adapter works completely fine outside of USB loaders. The Wiimmfi disc patcher in The Homebrew Channel lets me connect my physical discs to Wiimmfi without issue when I use my LAN adapter, so it's definitely not a matter of the adapter being incompatible with my Wii U at the hardware level. The games also connect fine to Wiimmfi through USBLGX when I use a wi-fi connection, but I really would prefer to use ethernet. I also tried everything again in WiiFlow and it was the same: wouldn't connect on ethernet, but worked on wi-fi.
If you guys have any insights into any settings that could fix this, I'd really appreciate it.
