I'm trying to connect my wii to my D-Link WBR-1310 wifi router. Im using a 128-bit SHARED key to encrypt my connection. Im unable to connect my wii. i get an error of 52030
I spent two hours yesterday trying to connect with 128 bit WEP and couldn't get anywhere.
Eventually, I had to *downgrade* my router firmware (!), switch to WPA Pre-Shared Key (which I am told is more secure than WEP anyhow), and switch from short preamble to long preamble.
You may also want to follow the usual advice too - choose channel 1 or 11, and set to "mixed/both" mode (different routers call it different things).
