Home network woes - AT&T 3800HGV-B Uverse and Netgear WPN824

Up until an unfortunate power outage, my home network has been operating acceptably.  Using AT&T, the DNS addresses are locked down.  Since I want to use OpenDNS, I connected my handy Netgear WPN824 to the router, fiddled for a while and it worked.

Today it stopped working.

What I want to do is have all of the computers in my home obtain internet access via the netgear router.  The router is connected to the AT&T modem.  The AT&T network is running 192.168.1.x while the netgear is at 192.168.2.x.  I've confirmed this with a hard connection.

I want to verify cable connections at this point.  Coming into the AT&T router, the wall connects to the phone line connection - this is the standard output.  The netgear cable is connected into one of the hub ports.

Q1: where does the connection from the AT&T to the Netgear go?  One of the netgear's hub ports or the internet connection?  I've tried this port and one of the hub ports, with and without powering off.  No joy.

Q2: Previously, I have had this working flawlessly with minimal configuration changes.  Searching around, I find numerous "tutorials" that don't quite get to me the solution.  This router is old, perhaps a newer router would make this simpler?

At wits end....

Jonah - yes, previously the network was set up with multiple routers in play - why is a family matter.  In any event, I have had this working, but it does appear to be fragile.  I will try to change the configuration such that I'll turn off the routing in the AT&T (not sure if this is possible - many features are locked down), and see how far I get.

Plug into the internet connection: finally a clear answer :).

Last night before posting this, the AT&T router complained that there was another router behind it, and would I like to let the 2nd router do it's thing? Got my hopes up, but not working yet.

--------

Dave - yes, AT&T provides my internet connection, runs into the ATT router then over to the netgear.  I've got another system here, so I should be able to connect my laptop to one, the system to the other, and see what I can do with a direct connection.  My experience has been that this issue is below the wireless connection issue - in this case, even the physically connected networks don't route properly.

Appreciate the suggestions -

I appreciate all the feedback, and I split the points.  The sad part about this situation is that there is nothing AT&T will do to help you... in any event... after I posted this question the AT&T router notified me that it had detected another router.  I simply said, yes, let it happen.

I have learned when we go into the monkey mode, to connect with an ethernet cable :)

So, after answering yes, still no joy.  I went to bed.  The next morning, it was all working again.  So, perhaps there is a time lag while AT&T, routers, etc. figure out how to handle things.
