NO/GREY WiFi on 3.1.3 / WORKING WiFi on 1.1.4 / NVRAM / SWIFI OK - PLEASE HELP!

hi,

I have an iphone 2g 16GB here which I restored first thing to a pwned 3.1.3 firmware.

everything worked except wifi and bluetooth.
(no mac address in settings and greyed out switches)

I went back to 1.1.4 and flashed fakeblank 3.9 BL to check if that would be an issue I could solve with swifi.

after restoring to 1.1.4, jailbreaking and unlocking with iliberty+ I noticed working wifi and bluetooth.

wifi and bluetooth mac adresses are shown in settings->about.

ibooter is reporting three different mac addresses and the wifi calibration data.

and swifi command which I executed nontheless tells me that there's nothing to fix.

I lose wifi and bluetooth when I go back to pwned 3.1.3. (I created a different ipsw the other time)

now I am back on 1.1.4 with 3.9FB.

I WOULD REALLY REALLY APPRECIATE SOME HELP TO SOLVE THIS ISSUE! :(:confused::(
THANK YOU VERY MUCH!

update:

I went back to BL 4.6 stock, neuter off and unlock off.
restored to 1.1.4 stock.
then restored to 3.1.3 stock.
redsn0w 0.9.4.
NO WIFI, NO BLUETOOTH.

now - again - back on 1.1.4 with WIFI and BLUETOOTH...
:confused:
