Topic: Did Nintendo break my DS settings?

OK. So way back in Feb I sent my 3DS in to get repaired due to a bad circle pad that loved to stay down even though it was centered. Came back fine. Now last week I was playing pokemon white to get prepared for Black 2, and it wouldn't connect me to the dream world no matter what I did. Later I found out that my nintendo DS profile got completely reset, so after redoing that, It worked fine.

Today I went to DSI transfer Uno to my 3DS, and for some reason, my DSI wouldn't connect to the internet during the transfer, yet it can connect to the store and do all of those other things. It gave me the error code 52001, but looking it up didn't help much.

So I Fixed the problem with DS games wi-fi, but what's the deal with my DSI not wanting to transfer uno without bringing the error message right as the transfer starts? Does it have anything to do with my 3DS, or what?

Already imported before, because I'm pretty sure you can only do it once?

You fixed the problem with the 'DS games wi-fi' setting on your 3DS, but that doesn't have anything to do with your DSi... if your DSi can connect to the DSi Shop and use the Internet Browser with no problem but has trouble playing DS games using WFC functionality, chances are your internet settings haven't been set properly on your DSi. Remember that DS games require a WEP connection, they can't do anything with WPA.

I'm talking about the system transfer to 3DS part... It won't transfer as the DSI drops right as it starts.

ah, i see what you're talking about now — for some reason i thought 'Uno' was the name of a pokemon you were trying to transfer from game to game between systems, lol. that particular error code seems to have to do with IP addresses on your network, perhaps your 3DS and DSi are grabbing for the same address at the same time. Have you ever had a problem transferring DSiWare between your systems before? if it worked before and isn't working now for some reason, the error code page at Nintendo recommends power cycling your router as a potential fix.
