Right ok,

How long after renewing your dhcp lease can you connect for. Ie when it
says expire 3 2006/9/6 18:35:22 is that when your connection drops? Or
is this totally unrelated, i wonder if the router is trying to be too
clever for its own good.

I don't understand why switching the router on and off helps in this
instant. What happens if you just unplug the cable? do you get the same
effect

If you have the correct deamons installed when you switch off or unplug
the router it will automaticly run ifdown eth0 and when the power/cable
is reconnected it will run ifup eth0, which in turn causes a new dhcp
lease to be obtained. This might be what is happening.

Can you confirm that when you loose connection issuing a dhclient as
root fixes the problem.

Also can you do a "ps -aux | grep dhclient" and see if dhclient has
backgrounded properly and if you have a load of them running or
something. dhclient should sit in the background after getting the first
lease then release at the required interval.

You may want to do a killall dhclient (if you have a load) which should
kill all instances then run just one and see how long you remain
connected. If you don't have killall just do "kill pid" (where pid is
the value(s) obtained (for process id) by doing the "ps -aux | grep
dhclient"

Richard Brown's "Oops internet problems" looks very similar in nature to
this one and the both your routing and dns entries are the same. Do you
both have the same router?
