I actually WOULD prefer my Netgear to be my sole wireless instrument (there would be possibly one or two items connected to it hard-wired, though). However, my Uverse 2Wire would serve as the main modem, into which are connected several items, from a DirecTV receiver to an Ooma telo to my PC and to a multiport switch.
Do your instructions above allow for such a configuration?
So, you would still have devices plugged into your 2Wire correct? If so, then you'll want to use the directions I provided. That allows your 2Wire to continue to act as a router, however, the Netgear is controlling wireless access to your network. The big thing is to turn off the DHCP server on the Netgear first and if the Netgear has a setting to be designated as an Access Point you need to select that option.
