Fast Gateway Network IP

@Al_Idaho to your original question - "Is there anyway to get the wireless network IP on the same network as the wan ports. As it is, the wireless is at 192.168.*.* however the wan ports are 172.27.*.*"

…I would say no. In general, T-Mobile Home Internet is designed for simple plug-n-play for the average consumer. Once you go into NAT and matching WAN and LAN IPs, you are out of their realm. 

That said, if I were you I would start from scratch.

1. Reset my Sagemcom and redo the setup (I have the same gateway and it works great)
2. Reset your Wi-Fi router and plug it into the Sagemcom for internet access
3. Set up the Wi-Fi router and have it spool addresses to your LAN devices
4. Touch each device and ensure a) they are set up for DHCP and b) pointing to your Wi-Fi router [for example my Sagemcom is 192.168.12.1 (they all are) and my Wi-Fi mesh router is 192.168.1.1
5. Once this is done you should have internet access to all your Wi-Fi connected devices, and  if your Wi-Fi router has Ethernet ports those can be getting internet access from your Wi-Fi router

Forget the idea of matching your LAN and WAN IP schema.

Let us know how it works.
