I've bought WVC54G three days ago in Bulgaria (Europe). The camera powers off after 20-40 minutes. Then i have to wait 3-5 minutes and reconect the power supply to restart the device. I saw a thread about this problem, but it was rather old. Since this camera is new (3 days old) I expected that this was solved by Linksys. Can someone who had that problem tell me a solution. Or is there an entire series of deffective cameras?
