Internet traffic enters the network via the T-Mobile supplied hardware and is routed into the ASUS Routers which provide the Luna Household network.
The Inseego modem (FX3100-1) requires an Android application (Inseego Mobile) to administer and requires you to be on the open network to log in to the UI; further information may be found in the LunaHouseholdCluster>Networking>LunaHouseOpenNetwork item within Bitwarden. This is configured to simply pass through traffic at the moment.
The two ASUS routers (both Wireless AC3000 - CT8, HW version A1) can be configured with the ASUS Router Android application or in the web application at router.asus.com. These routers are used to configure the Luna Household network.
