I have connected my DG45ID based computer to the AVM FRITZ!Box 7390.
Sometimes (often?) when I switch my computer back on it takes one or two minutes for Windows 7, 64 Bit, to recognize that it's connected to a network:
After Windows 7 has booted up, the NIC icon displays a red cross and network connection is down. Windows 7 then retries to establish a network connection every -say- 20 seconds, displaying the NIC icon with a green circle. This fails one or two times. Then, finally, after the second or third try, it can establish a network connection.
AVM support suggested me to post my problem to this forum and to ask whether the NIC's drivers could have problems dealing with an energy-saving switch. I told them that I have disabled energy saving mode at the FRITZ!Box already. Still they urge me to ask this question here.
Can someone enlighten me on what may be the problem here?
