hi all. first, sorry because am french and my english is poor I got this small nas a few days ago after having upgrad the unslug firmware I then wanted downgrad and to reconsider the firmware of origin, the nslu2 did not validate the order and remain injoignable on the network, with the twinkling led red/green. Not average to either join the nslu2 with the utility of cd's installation provided with the nas. in short, impossible to join it on the network, does somebody have a solution? thank you in advance.
