So in order to use Palantine/PBT/Pasta/patched rxTools you need to transfer a CIA Manager over the network. You're supposed to find the IP of your 3DS, edit run.bat with it and then start it. The IP is correct, pinging the 3DS works but after running run.bat the wireless light on the 3DS blinks and I get Failed to Connect every time. I've tried this on two lap tops, formatted the SD card and redid everything, tried using BigBlueMenu instead of DevMenu, turning the firewall off, making the network public without any password protection, setting a manual IP address/gateway, setting up a hotspot with Connectify and possibly some more stuff that I forgot about. I've searched quite a bit and I'm obviously not the only one who's had this problem, some recommended opening the browser after getting into the CFW and visiting a page but opening the browser freezes the 3DS everytime if the wireless is turned on. So my question is, did anyone go through something similar but was able to overcome the error or is it just the case of it works for some straight away without any hassle and doesn't and can't at all for others? Edit: Problem solved! Two of us (so far) solved this error after formatting the 3DS from the System Settings! Big thanks to @RepeatingDigits!
