Help Please provide me with original 2.1 all wpa_supplicant files

[mari133]

Hi,
can anyone provide me with the all original "wpa_supplicant" file in the 2.1 firmware (GT540).
I replaced it with other wpa_supplicant for enabling wifi ad-hoc network.
Sometimes I have error with switching on wifi, we succeed in turn can not find the network ;/

Thanks for helping me
