    I downloaded the latest firmware, I copied it to the /tmp and typed the command, after I got an error message saying, ... failed ... block
    and after, I am unable to connect to the wifi, ...
    any ideas ?
    flushing the firmware, with usb ?
    in any case, I think the WI-FI router is dead :(
    Just to learn from this situation :)
