New Internet wifi network reconfiguration
Please help me figure out this mess that needs to be reconfigured. I have been going in circles with Comcast support, Arris TG862G modem/router, Apple airport manuals, and Apple support forum postings for the past week and things are still not working correctly. The goal is to have my Comcast modem/router handle telephone/fax, printer, and internet signal (~105 Mbps) to the house. Then, I want to set up wireless throughout using Apple base stations. This house is 1700 sq ft with a concrete basement, 1st and 2nd floors. Every floor has desktops and needs wireless and/or ethernet for iphones, ipads, mac laptops, apple tv, directv, and audio receiver. All devices are apple except a gaming desktop PC in the basement and an old non-wireless PC on the 2nd floor. I have a brand new Airport Extreme (802.11ac model = A1521) , Time Capsule (802.11n model = A1409), and Airport Express (802.11n model = A1392) to configure a wireless network plus lots of ethernet too. All of my equipment is once again disconnected as it kept taking down my modem/router which is on 1st floor. I'm going to factory reset all of the base stations, relocate them (suggestions?) and start from scratch as multiple attempts have made a complete mess of things. Here are my present concerns and issues:
1) After I put the Arris TG862G modem/router into bridge mode and run the ethernet to the wan port on the first base station, should I set up the base stations in 'DHCP only' or 'DHCP and NAT' using airport utility?
2) If I set up the base stations (connected using ethernet) in this order Extreme, TimeCapsule, Express should configuration be the following?
- Extreme -> create a new network
- TimeCapsule -> extend a new network
- Express -> extend a new network
3) Is a base station password the same as the network password? I was confused about this and used the same password for both on every base station device. This seems to have confused the base stations. When I bring up airport utility, each base station appears like 'myGivenName(2)' rather than 'myGivenName'. Even prior resets are not wiping this out.
4) If I select 'off' rather than 'create a new network' or 'extend a new network' does this simply make the base station a fancy ethernet hub?
I appreciate any help since this very simple process has turned into a nightmare (picture family demanding action) :-(
