Networking :: D-Link DWL-G650 is not working

x-ray

Open the DSL Panel - select Iwconfig - your device would be "ath0". This utility should make the connection and creates the file "/opt/myiwconfig.sh". You can then easily connect later with the command "sudo /opt/myiwconfig.sh" As for automating searching for WLAN accesspoints when you reboot, edit the file "/opt/bootlocal.sh" (need to be root), and add "pump -i ath0" and "/opt/myiwconfig.sh"
