hmm thanks for the insight goldeye. How would I go about fixing this or are there any further tests I can do to figure out what exactly is the problem and hence how to fix it?

Weve seen someting very similar with other Belkin routers - can you please check that your router has the most recent firmware.

Apologies if this is the wrong place. I have just got hold of a DN60 but no power supply. The connector has a very small diameter and I am struggling to find a suitable power supply. Can anyone help...
