WNDR3700v2 router slow to connect to AT&T's modem's internet connection, after the modem has booted
Sorry I don't understand the header requested information, I tried to fill it out but it would not take what I typed.
I have a Netgear Router WNDR3700v2 that is slow to connect to my ATT Uverse modem's internet connection once the ATT modem has booted. The router and modem are powered up at the same time. The router always finds the internet connection but takes several minutes, as much as 5, after the ATT modem has fully booted. If I power down and re-power Netgear router it takes less than a minute to make the connection.
Leaves me thinking the router looks once for a connection and only again much later. Not that's correct but switching off the power and re-powering the router only, it makes the connection in less than a minute
Thanks for reading and any thoughts would be appreciated.

They're both routers and it causes a double nat.
A double nat happens when you cascade more than 1 router.

Fixes? There’s 3 options but only use 1.
1. Put the modem/gateway in modem only/pass through mode. This disables its routing functions.
2. Leave the modem/gateway in router mode but put the Netgears IP address into its DMZ. This forwards the data to the netgear. You can either leave the modem/gateway’s wireless enabled or disabled. Just make sure its using a different wifi channel to prevent interference
3. Put the Netgear into access point mode. This disables its routing functions. Wifi/ethernet still works but it does disable some features.

Thanks to the both of you for the quick replies

I am now aware of the 2 NAT problem thanks to your reply. I was searching since your reply the last 2 afternoons to refresh my memory & increase my knowledge. I certainly now have a better understanding now.
Option 3 -- Disables the Netgear router’s guest portion I use so that’s not OK.
Option 2 -- Seems like a reasonable choice from your advice but left wondering from my additional research. Which router will still be providing the firewall function and exactly how to option the BGW210-700.
Now thinking the BGW210-700 has an IPforwarding option but no DMZ option which I now believe turns off the firewall on the BGW210 and cures the double NAT problem?
1. Is this correct, Option 2 will also disable the BGW210-700’s Firewall which the WNDR3700v2 will then be doing?
2. Should I be looking at the IPforwarding option in the BGW210-700 to implement Option 2?

My old router, time for a new one is something I have also been wondering about.
3. Do the new routers provide significantly more security over my existing WNDR3700v2 router & BGW210-700 modem/router?
4. Do one or the both of you have any new router suggestions?
a. I noted looking, maybe a year ago, some routers came with lifetime updates too.
Thanks & Sure appreciate your assistance

Anything will be more secure than your 13-year old WNDR3700v2.
As to recommendations, try plugging your needs into the filters on the product pages:

Then check back here for reports on the things you are considering, but remember that people turn up in this community with problems, not compliments. So look at reviews on Amazon, for example.
plemans has explained the likely cause of your problem. I chip in only to warn you that the WNDR3700v2 dates back to 2010 and is seriously out of date on the wifi front.
Even when you do get it to work, don't expect too much.

That is not the way to go about it. You need to get the timing right.
- Turn off and unplug modem.
- Turn off router and computers.
- Plug in and turn on modem. Wait 2 minutes for it to connect.
- Turn on the router and wait 2 minutes for it to connect.
- Turn on computers and rest of network.
