I myself have no Wi-Fi problems on my build with TI WPA _SUPPLICANT. I think it might depend on the user's router/modem/security.
However, webdroidmt uses my build and have Wi-Fi problem. He replaced the wpa_supplicant.conf from the TI WPA_SUPPLICANT with non TI WPA_SUPPLICANT and it fixes it for him. Maybe someone here should test it out to see if it fixes the Wi-Fi problem for them.
All they have to do is edit the content inside /system/etc/wpa_supplicant.conf
