Re: Host AP mode with STA f/w v1.4.x

I want to upgrade the firmware of two cards with the 1.4.2 secondary firmware but I'm lost.

I'll try the RAM-download you have explained and If it works I prefer to chage the firmware forever.

¿what I need to do it? ¿a flash-download?
¿could you please point me to some web where explain how to do it?
¿Can it be done under linux or i need another S.O.?
¿Is dangerous?
