Logging in on my pc in the morning, there was no network at all!
Checked the sweex hub and the green light is shinning fine, not noticing its blinking. Reconfiguring the clarkconnect box and trying again, still no ip address for my pc. Well, it came to mind later that probably this blinking port is the problem. Changing my network cable to another port on the same hub does the trick... network available :o)
A rude morning memory jog especially on the weekend..
