After installing 3.51 M33, my favorite so far, with the addition of the M33-6 update, homebrew that use wifi can't connect at all.
I thought the M33-6 update would fix it because it has a wifi fix in it.. ..?
For example.. I try AFKIM (latest version) and it says "Connecting to wifi Failed"
It all worked on 3.40 OE. My Wifi also works great in the PSP browser in the XMB..
