R6400 and DM200 setup

Hi All,

Thank you for your assistance.

You were all helpful. The theme was set the modem into bridge (Modem) mode and configure the settings in the router with ISP username passowrd etc...

This would have been correct but I have not accepted any solution becuase of one thing that blocked it and the whole community needs to know. AC1750 does not have PPPoA. Even with latest firmware update. Confirmed by Netgear. What ????? Anyway no matter all your posts my ISP must have PPPoA so it never did work.

It is possible to leave the modem in modem+router mode, log in on the modem, say to the AC1750 that my ISP does not require a login, and then the modem will pass data to the AC1750. The problem here is you have double NAT double DHCP etc...

Fine, turn off the DHCP on one of them for example.... I tried that a lot but there were a lot of error mesages saying the IP on the router has been reset to 192.168.1.1 to avoid a clash with the ISP. In this case the ISP 'it' saw was the modem. The modem was passing a private IP to the router and that was stuck on 192.168.1.1, my whole network with many fixed IP's is on 192.168.2.x so I didn't really want to fiddle with that.

So long story short is that it didn't work terribly well at all. the root cause of all of the pain was no PPPoA in the AC1750 (R6400) - really poor netgear, considering it's quite highly priced.

Thanks all.
