It's customary to say
"Thank You" when someone helps you. Who knows? It might even be in your
own interests to do so. It might motivate people to help you again.
If you don't know what I'm talking about, or claim that you don't,
allow me to refresh your memory.

Your new post indicates that you now know to use ifup.
You're welcome.
As for your new problem, it looks like your DHCP server is set up to
hand out 1 hour leases. If the DHCP server is built in to the router,
as is often the case, that comes down to reconfiguring your router.
You want a fairly long lease time. You also want a fair amount of
time between when a lease is released (or when connectivity is lost)
and when that IP address is made available for reuse.
