Would you mind correcting this, it gets really annoying. devkitPro is a vendor of toolchains, you don’t use devkitPro for DS development, you use devkitARM – one of the products created by devkitPro.

Indeed, when I finish the series I will post the NDS client code as well as the PC host code. It should be pretty good. As far as the WEP stuff, there weren't any good examples out there, so I had to take a stab in the dark with my code and just hope it worked. My knife sank deep in some valid WEP authentication with DSWifi. The jist of it is that when you call Wifi_ConnectAP(...) the 4th parameter is the WEP key _bytes_, not the string representation of the bytes. Each character in a WEP key is a hex value that spans 4 bits, so you need to take two successive characters, convert each from character to bit representaton, and pack these two into a unsigned byte. Continue this until the terminating null of the string represenation of the WEP key is hit. You can then tell by the number of characters converted what type of WEP key it is. If it is 10 characters, it is a 40-bit key, if it is 26 characters, it is a 104-bit key. Strangely and quite confusingly, DSWifi defines WEPMODE_40BIT and WEPMODE_128BIT. One defined as the length excluding the initialization vector, and one defined as the length including the initialization vector. Very odd. Regardless, 10 char = WEPMODE_40BIT and 26 char = WEPMODE_128BIT. Hope this helps in the interim. I got a bit derailed on the project... you'll see why.

Trying to figure out the WEP stuff. Glad you caught that bug though! Is part 2 going to have examples on how to do this? I'm having trouble finding good documentation for the DSwifi library and all of its functions. I’m writing a telnet client w/ keyboard pretty much like how you have set up.
