Hi,  my motherboard is an Asus p5q with the built in Atheros lan chipset l1e.  I'm running Snow leopard with the Attansicl1e kext.  If i use my 100mbps switch the lan speeds are fast as they should be, around 10 to 12 megabytes a second transfers, but when i use my gigabit switch it really struggles to achieve anything near half of that.

The switch light for my lan port is green ( gigabit enabled ) so it auto negotiated fine but the speeds are really sluggish, i would say something like 2 to 5 megabytes a sec.

This is the thing though, when i boot into windows, the card runs great at gigabit full speed ( 40 to 60 megabytes a sec ).

All tests are done with a large iso file from my linux server over samba.  I've ordered a realtek 8169 based card to try instead of this onboard Atheros so i'll give that a go, but i would like to get the onboard working at full gigabit speeds if possible.
