Network or dhclient troubles on wheezy

["Lars Noodén" <lars.nooden@gmail.com>]

The network is frequently cutting out on a wheezy box I am running.  I
am not sure of where the problem lies, if it is on my box or at the ISP.

When it goes down, I am unable to connect:

	connect: Network is unreachable

/var/log/daemon.log is filled with a great many unfulfilled
DHCPREQUESTs, dozens at a time.

I can manually reconnect by running dhclient only if I release the DHCP
lease first.

Where should I be looking to find the problem and how should I go about
solving it?
