dswifi 0.3.3 also includes a fix to DHCP, but doesn't include your non-blocking fix. With dswifi 0.3.3, DHCP works for me now (and it didn't previously work before - I have a Netgear DG834Gv2 router). If you download the latest dswifi from sourceforge does it work for you? or is your nonblocking fix also required to get DHCP working for you? If so it would be worth contacting the dswifi developers (on irc on #dswifi) to get your patch tested/included!

Try using a more recent dswifi version! 0.3d came out a while back and 0.3.2 is now out too (0.3.2 is part of devkitpro so if you just use the regular devkitpro updater you should already have 0.3.2). I fixed a bug in 0.3.2 (so if 0.3.2 doesn't work with your router either, then wait for 0.3.3 to come out!). Email me privately if you would like me to mail you a test build of 0.3.3

I found and fixed a bug in the DHCP messages in dswifi (at least present in dswifi 0.3.2 and most likely in earlier versions). I did this by running a packet sniffer on my laptop to see the DHCP packets between my ds and my router. The client address field was not being padded/initialized with zero bytes before filling in the nintendo ds mac address. If the router looks at the entire field (all 16 bytes, i.e. the mac address and the next ten bytes too), then two subsequent DHCP messages would look like they come from different clients - my guess is that the router would reject/ignore them. The dswifi developers have already committed my patch to cvs so this will be fixed in dswifi 0.3.3 when it comes out! So we just wait for dswifi 0.3.3 now ..
