I'm using a D-Link usb -> WiFi Adater with success since 3 weeks

Yesterday evening, the link fall down and now i'm not more able to esabilish a wifi connection from WDTV and LAN.

I reflashed with a clean pen with the latest ext3 boot release, and the latest (0.03) version of wireless-mod.app.bin. The mount.config is unchanged (but i'm on dhcp on lan)

After tons of reboot, no results.

I tried my WiFi Pen with my pc and it works great... help ... What's going so wrong?
