Help with internet connections

[Orangespark24]

Hey guys, so i have been trying to connect to the internet via dolphin to access in-game dlc shops in some games, but it doesn't seem to work. I have tried using the .pem files method that i found on Youtube tutorial, but Error Code 23400 (Either nintendo wifi connection is experiencing high traffic volumes or the service itself) pops up. If i try to access it from Wii Menu settings, I go to Connection Settings. If i use a wired connection it makes me do a connection test and tell me it was succesful but then fails at updating the Wii, and the same thing happens if i use a wireless one. What do i need to do to get a connection that works? Is there any way for me to fix this? If you know of any way to get the emulated wii to connect, please tell me about it.
