Hello people. I have some problems. I have 2 different 3DS 1- Old 3DS XL 2- New 2DSXL I was playing online games with my old 3ds with Sky3ds card. After that i made CFW for it. But now i cannot connect to the internet. There is an error code 003-2101. Another New 2DSXL is connecting still. There is no error with it. I can play online games and can do everything. I test two of them with same wireless modem. I tried 3 different place with 3 different modem. But still same error with my old 3ds. But new 2DS is connecting. No problem. I tried to change proxy , dns. And i tried to make it static ip. I try everything what is writing on the forums. But Still nothing. What should i do do you think ? Is it about the CFW ? If yes can i uninstall it. If i uninstall the CFW the version will be 11.5. Can i made it CFW again ? I have my nanddump from 11.3 version.
