Loosing active DHCP client

Hi

I set up my edimax router and it appeared to be working correctly. In
the last week or so the connection drops and i cannot ping any site on
the internet.It seems the router is dropping the DHCP client, as when
there is no connection the Active DHCP Client box on the routers admin
page is blank, see below for some of the logs
