I need to use tablet to remote desktop control a laptop (XP) without using a wireless router. Modifying wpa_supplicant.conf fails to obtain address. Replacing wpa_supplicant (with everyone I can find on the net) gives an error. There is no tiwan.ini because this model uses Qualcom Atheros wifi chip instead of Texas Instruments. Need a developer who can modify and compile a wpa_supplicant binary file specificlly for this unit. If you can or know of someone that can, please reply.
