never heard about a 590 from dlink? in case you mean 580TX, please check kernel log... (in case you really mean 590, please post /etc/modules.conf [:)] )
It seems the product is discontinued (message on website from DLINK)
But I had red some good stuff about this card on this message board so it seems a little strange. I replaced the card with 2x 3c905 (reinstalled astaro V4) and now everything is fast again.
I found a problem with a new revision of this D-Link 580TX and the sundance module used in V4... I think this will be replaced (after some more testing) in an up2date...
YES please, DO some more testing and replace the driver, i just bought several for new customer installations ... and i thought to be clever to get some before they are totally sold out [:(]
