1. That download link (for Atheros) does not work any more.
2. Atheros L1 gigabit completely freezes my windows 7 x64 system (an asus laptop GS1) whenever I try to copy a large file (250 MB) to any network destination (standard windows workgroup using netbios). no bluescreen--just frozen solid.
3. mobrie's suggestion does not solve the problem.
4. I am using the latest windows 7 x64 drivers
available from microsoft (windows update) for the atheros: 18.104.22.168.
5. also sometimes freezes on printing to a networked printer (netbios again).
Thanks for any help.
