@Italens  I would really like to see them fix this so you could use your cellphones strive as a backup link.  This doesn't seem like it would be that hard to put into there system.

After a lengthy chat with support, the xxx-5G models (with internet back up) aren't available in the US.

I have the perfect solution for you! I’m actually using this exact setup while waiting for my new house to be connected to fiber.

You’ll need a Travel Router (like the TL-WR902AC or the TL-WR802N, which is what I use) configured in 'Client Mode'. This allows the device to pick up your phone's hotspot and pass the internet connection through its Ethernet port. Simply connect an Ethernet cable from the Travel Router to your Deco, and you’re all set!

Once your permanent internet line is installed, just swap the Travel Router for your ONT or modem.

Key Tips:

• Use 'Client Mode': This prevents the device from creating an unnecessary second Wi-Fi network.

• Set Deco to 'Router Mode': Ensure your Deco is set as a Router, not an Access Point.

• Bypass Hotspot Limits: This setup allows the Deco to handle all your devices. Since your phone only 'sees' the one connection from the Travel Router, you can bypass the typical device limits found on mobile hotspots.

I can guarantee this works from personal experience, though there is a trade-off in speed. Currently, I’m getting about 70 Mbps through the Travel Router, compared to the 600 Mbps I get when connected directly to my phone’s hotspot. I guess it depends on the 10/100 Mbps LAN port of the TL-WR802N. However, for a temporary setup, it is incredibly stable and handles all my smart home devices perfectly.

Hope this helps!
