I have two stores in two different sides of the same street, Each one has an ADSL connection with a wireless router and a different IP address.
So I have two different wireless networks connected to the Internet separately.
I want to share these networks so that when one ADSL router is disconnected from the Internet it will connect to the other network wirelessly to keep the connection.
I want the networks to be connected 24/7 in both the stores, and in case of ADSL problems in one of the networks, the other network will back it up.
I can't connect a cable between the stores, because there is a road between them.
How can I configure the routers to share my networks?
EDIT: The reason I'm asking this question:
I have two CCTV systems with DVRs, one in each store. Each is connected to its own router, and I want them both to be online even when one internet connection is lost.
This way I can always connect to the CCTV of both stores using my phone or home computer and know that everything is OK...
The solution of creating one wireless network seems good, but I need the DVRs to work on both networks, so I need the routers to connect to each other wirelessly (is that a word?).
I would also accept a solution involved with changing my hardware.
