Namie,
Try osprey4 suggestions or go to Netgears website and search. I know that Fa311 nic card had issues last year when they mistakenly mixed FA311 and Fa312 during production.
I bought a couple for $5 after rebates and worked great by reapplying the correct firmware to the FA311 (i think

)
On any case, that must be your problem, card is marked FA311 with a FA312 firmware, thus it thinks it is a FA312 nic card. Hope this help.
BTW, the cards are still wotking great.
