no, you want a failover.  Load balancing is trickier and is
not what you describe.

Sounds like it would be better to run your wireless router
in simple WAP mode instead of having it do NAT, to simplify
things, and install dnscache and squid or apache proxy on
the router, all the time.  And ntpd, and so  on.  Essentially you
become your own ISP providing service to the rest of your own
equipment, abstracting the details.  DHCP can still
live on the wireless router even in WAP mode, at least it can
on my old netgear muffin.
